Jason R. was awesome! He came out to service our tankless water heater and was super friendly, knowledgeable, and professional. He explained everything clearly and got the job done quickly.
Tankless Water Heater Installation in Vancouver, WA
Endless hot water and a mechanical closet you get back. We size it right, upgrade the gas and venting properly, and tell you honestly when tankless is not the right call.

Done right, tankless is a 20-year decision
A tankless unit heats water on demand instead of keeping 50 gallons hot around the clock, which is why the running costs drop and the hot water never runs out. The part most installers skim past: a gas tankless unit usually draws far more gas at full fire than the tank it replaces, so the existing gas line and venting often need to be upsized to do the job safely. We check that before quoting, not after opening the wall, and we handle the permit and inspection that Washington requires.
We install and service the major brands, and we service what we install. Our techs handle tankless maintenance calls across Clark County every week, including periodic descaling that keeps the heat exchanger efficient. If your household or your gas service makes a high-recovery tank the smarter buy, we will say so plainly. Free estimates either way, and $125 off a water heater installation when you mention the offer on this page.

Rated 4.9 stars by 690 customers
With a 20 year old, 80 gallon water heater on its last leg and leaking, I had many questions but little time. Jesse S. walked me through it on two separate occasions before the install.
Jason squeezed me in near the end of the day on a Friday and stayed late to get my water heater fixed. Prompt, communicated well, and saved my weekend.
