Tankless Water Heater Installation & Repair in Vancouver WA

Schedule Service

A tankless water heater heats water only when you turn on the tap, so you don't run out during back-to-back showers. Tri-Tech Heating, Inc. installs, services and repairs tankless water heaters across Vancouver, Camas, Salmon Creek and Clark and Cowlitz Counties — and because we already do the gas piping and the venting, it is one contractor rather than three.

Short answer: Tankless suits homes that run out of hot water or want the floor space back. It costs more to install than a tank, mostly because of the gas supply and venting it needs. Estimates on new installations are free. Call (360) 891-2002.

Is a tankless water heater right for your home?

  • Endless hot water. It heats water on demand instead of storing it, so it doesn't run out.
  • Smaller footprint. The unit mounts on the wall and frees up floor space.
  • Longer life. Rinnai rates its tankless units for up to 20 years of life, about twice a typical tank.
  • Lower running cost. According to ENERGY STAR, a certified gas tankless water heater can save a family of four about $95 a year compared with a standard gas tank.
  • Higher cost to install. Gas models need adequate gas supply and their own venting, which is where the real cost difference usually sits.

We will tell you which option actually suits your house, including when a standard tank is the right answer.

Tankless water heater installation in Vancouver WA

We generally install Rinnai tankless water heaters. A tankless installation is more than swapping one unit for another:

  1. What you have and what you need. Household size, peak demand, fuel available, and where the unit lives.
  2. Gas supply. A tankless unit often needs more gas supply than the old tank did. We do the gas piping.
  3. Venting. Gas tankless models need their own venting, and we handle that too.
  4. Permit where the work requires it.
  5. Test and hand over. Temperature set safely, connections checked, and the old unit taken away.

Tankless water heater repair

Tankless units fail differently from tanks. Most calls come down to scale buildup, a venting fault or an ignition problem, and the unit usually shows an error code. Hot then cold mid-shower is usually a flow or scaling issue. We service Rinnai and other tankless models. See water heater repair for other types.

Yearly flush and maintenance

Tankless units need a yearly flush to clear mineral buildup, and we can take care of that for you.

Warranty and financing

  • 2-year labor warranty on new installations, and 1-year labor warranty on repairs
  • We register your new equipment for the full manufacturer warranty
  • Financing through Synchrony for qualified buyers (apply online)

Tankless water heater questions we get

Is a tankless water heater worth it?

For many homes, yes. A tankless water heater doesn't run out of hot water during back-to-back showers, lasts longer than a tank and takes up less space. ENERGY STAR estimates a certified gas tankless model saves a family of four about $95 a year compared with a standard gas tank. It costs more to install, so we'll compare the options for your home.

How long does a tankless water heater last?

Tankless water heaters can last up to 20 years with a yearly flush. Water quality, usage and maintenance all affect how long yours lasts.

Can I replace a tank water heater with a tankless one?

Usually, yes. Gas models need adequate gas supply and their own venting, which is where the real cost difference usually sits. The site visit establishes what your house needs.

Does a tankless water heater need maintenance?

Yes. Tankless units need a yearly flush to clear mineral buildup, and we can take care of that for you.

Estimates on new equipment and installations are free. A repair on an existing unit is a service call.
