Tankless Water Heater Installation in Big Bear Lake, CA
Endless Hot Water. No Tank to Freeze.
Tankless water heaters heat water the instant you turn on the faucet — no 40-gallon tank sitting in your garage burning gas 24 hours a day. They last nearly twice as long as tank units, cut water heating costs by 20-30%, and for Big Bear cabin owners, they eliminate one of the biggest freeze risks in an unoccupied home.
We install all major tankless brands: Rinnai, Navien, Noritz, and Rheem. Gas and electric. Indoor and outdoor mount.
Why Tankless Makes Sense in Big Bear
- Freeze protection — No tank of standing water means no 50-gallon ice block in your garage when the cabin sits empty. Modern tankless units have built-in freeze protection that activates automatically.
- Space savings — A tankless unit mounts on the wall and frees up floor space where your old tank sat.
- Energy savings — You only heat water when you’re using it. Full-time residents save $100-200 per year on gas bills.
- Longevity — 20+ year lifespan vs. 8-12 for a tank. That’s one replacement instead of two over the life of your home.
- Unlimited hot water — Fill the tub, run the dishwasher, and take a shower at the same time. No more waiting for the tank to recover.
What the Installation Involves
Converting from a tank to tankless isn’t just a swap. It requires:
- Gas line evaluation — Tankless units often need a larger gas supply. We’ll verify your gas line can handle the BTU demand and upgrade it if needed.
- Venting — Tankless units require Category III stainless steel venting or PVC (for condensing units). We install new venting to code.
- Condensate drain — Condensing tankless units produce acidic condensate that needs proper drainage. We install a drain line and neutralizer.
- Electrical — Even gas tankless units need a 120V outlet for the control board and ignition.
- Mounting and connection — Wall mounting, water supply and return piping, and all connections.
- Testing and calibration — We set the output temperature, test flow rates at every fixture, and verify the unit is operating at peak efficiency.

Is a tankless water heater worth it in Big Bear?
For full-time residents, a tankless unit saves 20-30% on water heating costs and lasts nearly twice as long as a tank unit.
