Navien tankless water heaters are famous for being some of the most energy efficient water heaters you can buy, thanks to their condensing technology that uses waste heat to pre-heat incoming water. Navien was one of the first brands to produce condensing water heaters, and they’re still one of the most reliable.


By choosing a tankless water heater, you can enjoy these benefits:

  1. They have a much longer life expectancy than standard hot water tanks: 20 or more years, compared to 10 – 15 years for a tank.

  2. Tankless models are much more energy efficient than water tanks. Model efficiency ratings vary, but on average you can expect to save $100/year on energy. With some condensing models, savings of around $160 per year can be expected.

  3. They provide endless amounts of hot water – that means no more sudden, unintended cold showers!

  4. Because they are small boxes that mount on a wall, tankless water heaters free up a lot of space in your basement or utility area.

  5. Tankless water heaters are flood proof. When conventional hot water tanks fail, the result is often a spectacular flood. Almost all tankless models have emergency features to detect water heater leaks and prevent similar situations.

  6. Tankless water heaters generally qualify for rebates to help offset the cost of installation.

  7. For very high-demand households, installing two units in parallel can ensure there’s enough hot water when everyone turns on the tap at once.

Here are a number of great reasons to pick a Navien for your home. All of the Navien water heaters we carry come with these great benefits (individual specs are shown below):
  1. Ultra efficient. All models are EnergyStar qualified.

  2. Installation is much cheaper than some tankless brands. Naviens use the same gauge gas line (½”) as your old water tank. No need to upgrade your gas line.

  3. Easy installation and servicing. Regular 2” PVC pipe can be used for venting because only a small amount of heat escapes from the unit. Venting pipe runs can be up to 60 feet long.

  4. Almost no waste of heat. Navien is a leader in condensing technology, in which waste heat is captured and used to preheat the incoming water supply.

  5. No “cold water sandwich”. The ComfortFlow recirculator ensures hot water on demand, with no breaks in the supply of hot water.

  6. Works no matter how much hot water you need. For very large hot water demands, two or more units can be used.

  7. Excellent warranty coverage. Up to 15 years on the heat exchanger and 5 years on other parts and components, plus 1 year labour (will depend on other equipment your Navien is connected to).

  8. Built to last. Heat exchangers are made of stainless steel to resist corrosion better than standard copper exchangers. Stainless steel also resists that white scale mineral buildup that results from hard water. Navien was the first manufacturer to use stainless steel.

  9. Qualifies for a number of provincial and other rebates. Ask Husky which rebates are happening now.

  10. Almost zero risk of flooding. Navien uses a special failsafe device to shut off the water in the event of a problem.

  11. Wi-fi remote controllable. The New NaviLink technology allows you to control your water heater and get usage data from your smartphone.

  12. Ultra low emissions. NOx ≤ 20 PPM.

Serving homes and businesses across Vancouver and the Fraser valley , Grove Mechanical can install newer, energy-efficient water heaters that are more compact and easier to maintain. Our team can professionally install a new water heater to ensure it is properly connected and works flawlessly. A thorough assessment of your home and hot water needs helps us determine the best model to install. Having to replace your water heater can be a surprise and financially straining decision, but we’ll assist you every step of the way, from choosing the best model to offering free estimates, competitive pricing, and financing. Installing a new water heater has many benefits, so once we complete the job, you’ll likely benefit from:



Newer hot water heaters consume less energy and heat water more efficiently. Energy Factor ratings, which measure the amount of hot water produced per unit of fuel, are improved as well.

We can install a more compact electric water heater, while tankless water heaters save the most space; they are small enough to mount on a wall and can be tucked away in a closet. This leaves room for additional storage in your home.


Old water heaters lose efficiency and may leave you with a cold shower, not to mention reduced water quality. We can eliminate the need for tanks, so your hot water is continuously refreshed and provided when needed.
