This guide is designed specifically for homeowners in Kelowna, Vernon, and Penticton, breaking down the costs and process. We’ll cover everything you need to know to confidently get a quote for tankless water heater installation from a team that knows our community.

Key Takeaways

Understand What Drives the Cost: Your final quote reflects more than just the unit; it includes necessary gas, venting, and electrical upgrades specific to your home. A professional on-site assessment is the only way to get an accurate price, which typically ranges from $3,000 to $8,000.
Vet Your Contractor Carefully: The quality of your installation is just as important as the unit itself. Always choose a licensed and insured professional with proven experience, positive reviews, and transparent, upfront pricing to protect your home and your warranty.
Plan for Long-Term Performance: A successful installation starts with preparing your home and ends with consistent care. Simple annual maintenance, like descaling, is essential to ensure your tankless system delivers efficient, on-demand hot water for its full 15-20 year lifespan.

What is a tankless water heater?

If you’re tired of running out of hot water or paying to heat a big tank of it 24/7, a tankless water heater might be the perfect fit for your home. Unlike traditional water heaters that keep a large volume of water hot in a storage tank, a tankless system is an on-demand water heating system. It heats water instantly, precisely when you need it, which means you get a continuous supply for as long as you need it. This is a game-changer for large households or anyone who enjoys a long, hot shower without the water turning cold.

These systems are also incredibly space-efficient. Because there’s no bulky tank, they are compact, wall-mounted units that can free up valuable floor space in your utility room or closet. They work by passing cold water through a powerful heating element—either gas or electric—the moment you turn on a hot water tap. The result is an endless supply of hot water and significant energy savings, since the unit isn't constantly working to maintain the temperature of stored water. This process eliminates what’s known as standby heat loss, a common issue with traditional tanks.

How on-demand heating works

The magic of a tankless water heater is its simplicity. When you turn on a hot water faucet, a flow sensor inside the unit detects the moving water and activates a high-powered burner or electric element. This heating component quickly raises the water to your preset temperature as it passes through. When you turn the tap off, the unit shuts down completely. This direct approach to heating means you aren't wasting energy keeping dozens of gallons of water hot around the clock, which is exactly what your old tank-style heater does. It’s a smarter, more efficient way to manage your home’s hot water needs.

Save space and lower your energy bills

One of the most immediate benefits you'll notice after switching to a tankless system is the extra space. These compact units mount directly to a wall, freeing up an entire closet or corner of your basement. Beyond the extra room, the real advantage is the impact on your utility bills. By heating water only when needed, tankless water heaters can be 24% to 34% more energy-efficient than conventional models. This efficiency translates directly into monthly savings, helping the system pay for itself over time. You can find even more ways to save by checking out available rebates and offers on new installations.

Enjoy a longer lifespan and better performance

A tankless water heater is a long-term investment in your home’s comfort and value. These units are built to last, with a typical lifespan of 15 to 20 years—nearly double that of a traditional tank heater. This durability means fewer worries about leaks, replacements, and unexpected cold showers. The performance is also a major upgrade. With a properly sized unit, you get an endless supply of hot water, so you can run the dishwasher, do a load of laundry, and have someone shower simultaneously without running out. To get the most out of your system, regular maintenance is key, which is easy to manage with a membership plan.

What affects the cost of a tankless water heater installation?

When you ask for a quote to install a tankless water heater, you’re getting more than just the price of the unit. The final cost is a complete picture of the equipment, the skilled labor required, and what it takes to integrate the new system safely and efficiently into your home. Because every home in the Okanagan is unique, a one-size-fits-all price doesn't exist. Factors like your home’s existing plumbing, the type of unit you choose, and necessary upgrades all play a role.

Understanding these variables helps you see exactly what you’re paying for. A trustworthy quote should be transparent, breaking down the costs so you can make an informed decision about your investment. At TruFinity, our goal is to provide a clear and detailed estimate that reflects the specific needs of your home and family. We believe in upfront pricing to eliminate surprises, ensuring you feel confident in the value you’re receiving. Our process starts with understanding your home to provide a quote that is tailored to you.

The type and size of your unit

The biggest factor in your quote is the tankless water heater itself. You’ll choose between natural gas and electric models, with gas units typically having a higher upfront cost but lower long-term operating expenses. The unit's size, measured in gallons per minute (GPM), is also critical. A small condo for one person has very different hot water needs than a large house with multiple bathrooms and a family of five. Our team performs expert flow rate calculations to match you with a unit that can handle your peak demand, so you never have to worry about a cold shower. A larger, more powerful unit will naturally cost more than a smaller one.

Your home's current setup

Switching from a traditional storage tank to a tankless system isn't always a simple swap. The location of your old tank might not be ideal for the new, wall-mounted unit, which could require rerouting water lines. The condition of your existing plumbing also matters. If your pipes are old or not up to code, they may need to be updated to support the new system. Our Red Seal Plumbers will assess your current setup during our on-site consultation to identify any necessary modifications. This ensures the new heater integrates seamlessly with your home’s plumbing system for reliable, long-term performance.

Necessary upgrades for gas, electric, and venting

A tankless water heater often requires more power than a traditional tank, which can mean making some important upgrades. Gas models, for instance, might need a larger gas line to provide enough fuel, along with new, specialized venting to the outside. Our technicians have their Class B Gasfitter Certification, ensuring this work is done safely. Electric models can draw a lot of power and may require a new, dedicated circuit or even an upgrade to your home’s main electrical panel. These upgrades are essential for safe operation and are a standard part of a professional heating installation.

Local permits and code compliance

A professional installation always follows local building codes, and in many cases, this requires pulling a permit. While it might seem like an extra step, permits are there for your protection. They ensure the work is done to a safe and professional standard, which is crucial when dealing with gas lines and high-powered electrical systems. The cost of the permit is typically included in your overall quote. A reputable contractor will handle the entire permitting process for you, giving you peace of mind that your new tankless water heater is installed correctly and legally, protecting your home and your family.

How much does it cost to install a tankless water heater in the Okanagan?

Let's talk numbers. We know that budget is a big factor when you’re considering a major home upgrade like a new water heater. While a tankless unit is a smart investment that pays off in energy savings and convenience, the upfront cost is higher than a traditional tank. The final price tag depends on the unit you choose, your home’s existing plumbing and gas lines, and any necessary venting modifications.

At TruFinity Home Services, we believe in complete transparency. While every installation is unique, we can give you a clear picture of what to expect and show you how to make this valuable upgrade more affordable.

What Okanagan homeowners can expect to pay

This covers the new unit, professional installation by our certified technicians, and any required modifications. The wide range accounts for variables like the size of the unit needed for your family, the complexity of the venting, and whether your gas line needs to be upgraded to meet the new heater's demands. For a precise, no-surprise price tailored to your home, the best first step is to schedule a service consultation with one of our experts.

What are some common myths about tankless installation?

Switching to a new technology like a tankless water heater can feel like a big step, and it’s easy to get tangled up in misinformation. You’ve probably heard a few things about these systems that gave you pause. Are they really as good as people say? Do they come with hidden drawbacks? It’s completely normal to have questions.

Let's clear the air and look at some of the most common myths surrounding tankless water heaters. Understanding the facts will help you see why so many homeowners in the Okanagan are making the switch. We'll separate the fiction from the reality so you can feel confident about your decision. From energy use to the complexity of the installation itself, here’s what you really need to know.

Myth: They use more energy

This is one of the biggest misconceptions out there. The reality is the exact opposite: tankless water heaters are celebrated for their energy efficiency. A traditional tank-style heater has to work around the clock, constantly burning fuel to keep a large volume of water hot, just in case you need it. This process, known as standby heat loss, is a major source of wasted energy in many homes.

A tankless system, on the other hand, only heats water when you turn on the tap. It provides hot water on demand, which means it eliminates standby heat loss entirely. You only pay to heat the water you actually use, leading to significant savings on your utility bills over time.

Myth: You'll run out of hot water

This myth likely comes from a misunderstanding of how the technology works. With a traditional tank, you absolutely can run out of hot water. Once that 40- or 50-gallon reserve is gone, you’re stuck waiting for it to refill and reheat. A tankless water heater solves this problem by providing a continuous, endless supply of hot water.

Because it heats water in real-time as it passes through the unit, it never runs dry. As long as you have water and a power source, you have hot water. This is a game-changer for families, especially when you need to run the dishwasher, a load of laundry, and a shower at the same time. The key is ensuring the unit is properly sized for your household’s needs, which is a core part of our professional heating services.

Myth: Installation is always complicated

While installing a tankless water heater is more involved than a simple tank swap, "complicated" isn't the right word when you have an experienced team on the job. The process often requires upgrading gas lines to meet the unit's demands, as well as installing new venting. This isn't a DIY project—it requires certified professionals to ensure everything is safe and up to code.

For our team of Red Seal Plumbers with Class B Gasfitter Certification, these tasks are routine. We handle the entire process, from assessing your home’s needs to making the necessary upgrades for a seamless and secure installation. For a professional, it’s a straightforward job that ensures your new system runs safely and efficiently for years to come.

What information do you need to get an accurate quote?

Getting a quote for a new tankless water heater shouldn't feel like a pop quiz. The goal is to get a clear, accurate number so you can budget properly and make the right choice for your home. While any professional technician will perform a thorough on-site assessment, you can speed up the process and ensure total accuracy by gathering a few key pieces of information beforehand. Think of it as doing a little homework to make the final exam—the installation—go perfectly.

Having these details ready helps our team understand your specific needs right from the start. It allows us to prepare for the consultation and avoids any surprises down the line. This preparation ensures the quote we provide is tailored precisely to your home, your family, and your hot water demands. It’s a key part of our commitment to upfront pricing and transparency, making sure you feel confident and informed every step of the way. When you know what to expect, you can focus on the exciting part: enjoying endless, on-demand hot water.

Your current water heater and home specs

First, let's talk about what you have now. Knowing the details of your current water heater gives us a starting point. Is it a gas or electric model? How old is it, and where is it located? This information helps us plan for the switch, especially if we're handling a conversion from a traditional tank to a tankless system. We also need to know a bit about your home, like its square footage and the number of bathrooms. These specs are crucial for sizing your new unit correctly, ensuring it can handle all your plumbing demands efficiently. As experts note, installation costs can vary widely based on factors like fuel type, so having this info ready is a big first step.

Your family's hot water habits

Next, consider how your household uses hot water. This isn't about judging your long showers—it's about making sure your new system can keep up! How many people live in your home? Do you frequently run the dishwasher while someone is showering? Do you have a large soaker tub that needs filling? Answering these questions helps our technicians perform the right flow rate calculations to match you with a unit that provides endless hot water exactly when you need it. This ensures you won't experience a drop in performance during peak usage times, which is one of the main benefits of our advanced tankless water heater installation.

Where the new unit will go

Finally, the physical location of the new unit plays a big role in the installation plan and final cost. Tankless water heaters are compact and wall-mounted, which gives you more placement options. However, the chosen spot needs proper access for venting, plumbing, and your home's gas or electrical lines. If the new unit is going into a tight space like a crawlspace or requires rerouting lines, it can add to the labor involved. During our on-site consultation, we’ll assess the potential locations to find the safest and most efficient spot, ensuring everything is up to code and works perfectly for your home's layout.

What should a professional installation quote include?

When you get a quote for a tankless water heater, you’re looking for more than just a final price. A professional quote is a detailed roadmap for your project. It should be clear, comprehensive, and give you total confidence that you’re working with a team that values transparency and quality. A vague or confusing quote can be a red flag, but a detailed one shows that the contractor has done their homework and respects your investment. It’s your best tool for understanding exactly what you’re paying for, from the equipment itself to the skilled labor required for a safe and efficient installation. At TruFinity, we believe in providing upfront pricing and detailed inspections to eliminate any surprises.

A thorough site assessment and sizing

A trustworthy quote always starts with an in-person visit. An experienced technician needs to see your home’s unique layout to provide an accurate price and installation plan. During this assessment, they’ll evaluate your current plumbing, electrical panel, and gas lines to determine what’s needed for a seamless transition. They will also perform crucial flow rate calculations to understand your household’s hot water usage. This ensures the recommended unit is perfectly sized to meet your family’s needs without wasting energy. This step is non-negotiable for a proper installation that complies with all local codes and regulations.

A clear breakdown of costs

Your quote should break down every expense so you can see exactly where your money is going. A single lump-sum price isn’t enough. Look for an itemized list that includes the cost of the tankless unit, labor, materials like piping and venting, and any necessary upgrades to your gas or electrical systems. It should also account for permit fees. While a typical tankless water heater replacement can range from $3,000 to $8,000, the exact cost depends on your home's specific needs. The precise cost for permits or specific parts is not available in the knowledge base, as it can only be determined after a site visit. We also offer flexible financing options to help make the investment more manageable.

Details on warranties and guarantees

Your new tankless water heater is a significant upgrade, and your quote should clearly state how it’s protected. There are two key warranties to look for. First is the manufacturer’s warranty, which covers the unit itself. A professional installation by certified technicians is essential, as improper work can void this coverage. Second is the labor warranty, which covers the workmanship of the installation. This is a promise from your contractor that the job was done right. We stand behind our work and offer a two-year labor warranty to members of our TruLoyalty+ plan, giving you lasting peace of mind.

What should you look for in an installation contractor?

Choosing the right tankless water heater is only half the battle. The quality of the installation is just as important as the quality of the unit itself. A poor installation can lead to performance issues, safety hazards, and even void your manufacturer's warranty. You need a contractor who not only knows the equipment but also understands the unique plumbing, gas, and electrical systems in Okanagan homes.

When you're vetting potential installers, focus on three key areas: their qualifications, their reputation, and their business practices. A great contractor will be fully licensed and insured, have a long list of happy customers, and be completely transparent about their pricing and guarantees. Taking the time to find a qualified professional ensures your new system will provide endless hot water safely and efficiently for years to come.

Proper licensing and local expertise

A tankless water heater installation is a complex job that involves your home’s plumbing, electrical, and gas lines. This isn't a DIY project—it requires a licensed professional to ensure everything is done safely and up to code. Hiring a certified technician is the best way to protect your home, your family, and your investment. At TruFinity, our team includes Red Seal Plumbers and technicians with Class B Gasfitter Certification, so you can be confident the work is done right. Proper installation by a certified expert is also essential to keep your new unit’s manufacturer warranty valid.

Proven experience and positive reviews

Look for a contractor with a strong track record of successful tankless water heater installations. An experienced team will know how to properly size your unit and handle any surprises that might come up during the installation process. The best way to gauge a company's experience is by reading what past customers have to say. Checking reviews gives you honest insight into a company’s workmanship and customer service. As one of our customers said, "Julian installed our new tankless water heater and filtration system and we were very happy with both him and the level of service he provided. He did a very good job and you can tell he takes pride in his workmanship."

Upfront pricing and solid guarantees

A trustworthy contractor will always provide a clear, detailed, and upfront quote before any work begins. You should never have to guess what the final bill will be. We believe in "upfront pricing" to eliminate surprise charges and ensure you feel comfortable with the entire process. Beyond the initial cost, ask about the warranties they offer. A solid guarantee shows that a company stands behind its work. Proper installation ensures your equipment’s manufacturer warranty is protected, and we offer an additional two-year labor warranty for our TruLoyalty+ members for extra peace of mind.

How can you make your installation day go smoothly?

A successful installation is a team effort. While our certified technicians handle the technical work, a little preparation on your end can make the entire process faster and more efficient. Knowing what to expect helps ensure there are no surprises, so you can start enjoying your endless hot water even sooner. From clearing a path to understanding the final system test, here’s how you can help make installation day a breeze.

How to prep your home for installation

Your preparation starts before our truck even pulls up. The most helpful thing you can do is ensure our technicians have a clear and safe path to the work area. Please clear any furniture, boxes, or other obstacles from the route between the entrance of your home and your current water heater. It’s also important to create ample space around the unit itself. This allows our team to work safely and efficiently when removing the old tank and installing the new tankless system. If you have pets or young children, arranging for them to be in a separate, secure area of the house helps keep everyone safe and minimizes disruptions.

What to expect on the day of

On your scheduled installation day, one of our professional, certified technicians will arrive ready to get the job done right. They will have your new tankless water heater and all the necessary tools for the installation. We always begin by protecting your home, laying down drop cloths to keep the work area clean. The technician will then disconnect and remove your old water heater before starting the new installation. As part of our commitment to upfront pricing, any complexities, like needing to work in a tight crawlspace or attic, would have been discussed during your initial quote, so there are no surprise fees. Our goal is to make the process seamless and respectful of your home.

The final walkthrough and system test

Once the installation is complete, our job isn't finished. Your technician will thoroughly clean the work area, removing the old unit and any debris. Next, they will perform a complete system test to ensure your new tankless water heater is running perfectly and providing hot water to all your fixtures. This is your opportunity to ask any questions you have. We’ll walk you through the system’s basic functions and any maintenance tips. We’ll also finalize the paperwork and discuss payment, including any financing options you’ve chosen. We won’t leave until you are completely comfortable with your new system and 100% satisfied with our work.

How do you maintain a tankless water heater?

Your new tankless water heater is built to last, with a typical lifespan of 15-20 years. But just like any other major appliance in your home, it needs a little care to perform at its best. Think of it like a regular tune-up for your car—a small investment in maintenance prevents big headaches and costly repairs down the road. Keeping up with simple, annual service ensures your unit runs efficiently, delivers that endless hot water you love, and reaches its full lifespan.

For homeowners in the Okanagan, where mineral content in the water can be a factor, proactive maintenance is especially important. Over time, mineral deposits can build up inside the unit, forcing it to work harder and reducing its efficiency. A straightforward annual service plan is the best way to protect your investment and keep your energy bills in check. It gives you the peace of mind that your system is clean, safe, and ready to handle your family’s needs year-round.

Why annual service is key

Scheduling an annual service for your tankless water heater is one of the smartest things you can do as a homeowner. This proactive check-up is crucial for the unit's longevity and efficiency. A professional technician can spot small issues before they turn into major problems, saving you from the stress and expense of an emergency breakdown. Regular service also ensures your system is operating at peak efficiency, which helps keep your energy costs low. More importantly, many manufacturer warranties require proof of regular maintenance, so staying on top of annual service helps keep your investment fully protected.

Cleaning filters and inspecting the system

The most important part of annual maintenance is descaling the system. This process removes the mineral buildup (limescale) that naturally occurs as water is heated. If left unchecked, this buildup can clog the heat exchanger, reduce water flow, and make your unit work much harder than it should. A professional service call includes a full system flush to clear out these deposits. Our technicians also clean the inline water filters and inspect all components to ensure everything is working correctly. This is also a great time to consider a whole-home water filtration system to protect all your appliances.

Making maintenance easy with a membership plan

We know life gets busy, and it’s easy to forget to schedule annual appointments. That’s why we created our TruLoyalty+ Membership to make maintenance simple and stress-free. This plan includes the annual "Tankless water heater service" and flush your system needs to stay in top condition.

Frequently Asked Questions

Is a tankless water heater really worth the higher initial cost? It’s true that the upfront investment for a tankless system is more than a traditional tank, but it’s an investment that pays you back over time. Think of it in two ways: lower monthly bills and a much longer lifespan. Because the unit only heats water when you need it, you’ll see a noticeable drop in your energy consumption. Plus, these systems last nearly twice as long as a standard tank, meaning you won’t have to worry about a replacement for up to 20 years. When you factor in the energy savings and the cost of buying a second tank heater down the line, the value becomes very clear.

How long does a typical installation take? A standard tankless water heater installation is usually completed within a single day. It’s a more involved process than a simple tank swap because our technicians may need to upgrade your home’s gas lines, venting, or electrical circuits to support the new unit safely. We take the time to do the job right, ensuring every connection is secure and up to code. Our team will give you a more precise timeline during your on-site consultation so you know exactly what to expect.

Will my tankless water heater work if the power goes out? This is a great question, and the answer depends on the type of unit you have. Both gas and electric tankless models require electricity to operate their electronic controls and sensors. This means that during a power outage, neither type will be able to produce hot water without a backup power source like a generator. This is an important consideration for any homeowner when weighing their options.

Can any home be fitted with a tankless water heater? Most homes can be successfully retrofitted with a tankless water heater, but it’s not always a simple swap. The key requirements are having adequate space for the new venting system and ensuring your home’s gas or electrical systems can handle the unit’s power demands. This is why a professional on-site assessment is so important. A certified technician can evaluate your home’s specific layout and infrastructure to confirm compatibility and map out the best installation plan.

How much can I realistically expect to save on my energy bills? The exact amount you save will depend on your family’s hot water usage, but studies show that tankless water heaters can be up to 34% more energy-efficient than traditional storage tanks. By eliminating standby heat loss—the energy wasted keeping a large tank of water hot 24/7—you’ll see consistent monthly savings. Over the 15- to 20-year lifespan of the unit, these savings add up significantly, helping the system pay for itself.
