Our take on the Eccotemp SH22-NG

The Eccotemp SH22-NG is a natural gas tankless water heater built for whole-home or multi-fixture use. It fires up to 6.8 GPM and modulates its burner to hold a steady temperature, with a digital display for setting and monitoring output. It is a step up from Eccotemp's smaller portable and mid-size units, and it competes with other gas tankless heaters on flow rate and venting flexibility rather than on extras. Reviewers like the output for the size and the simple wall mount, but some owners report ignition and temperature-fluctuation issues and want clearer installation guidance.

Questions and answers

Is the SH22-NG big enough for a whole house?
It is rated for whole-home use and can run two showers plus a sink at once in most homes. Very large houses with simultaneous heavy demand may need a higher-capacity model.
Does it work with propane?
No. This is the natural gas version. Eccotemp sells separate propane models, so check the fuel type before buying.
What venting does it need?
It is a condensing unit that vents through PVC, which is simpler than stainless steel venting. Follow the manual for vent length and termination, and check local code.
Can I install it myself?
Only if you are comfortable with gas line sizing, venting and condensate drainage. Most owners hire a licensed plumber or gas fitter for the install.
Does it need electricity?
Yes. It uses a standard household power connection for the controls, display and ignition, so plan an outlet near the unit.
How does it compare with Eccotemp's smaller units?
It delivers more flow and whole-home capacity than the portable and mid-size models. The trade-off is a harder install and a need for proper venting.
Where is the Eccotemp SH22-NG cheapest?
At The Home Depot, for $499.00, 35% under what the other stores charge, as of our latest check.
