The right water heater depends on how your household uses hot water, your fuel, and the install. Weigh these:

UEF (Uniform Energy Factor) is the standard efficiency measure for water heaters, higher is better. For a tank, the first-hour rating tells you how much hot water it can deliver in a busy hour; for a tankless, the gallons-per-minute rating tells you how many fixtures it can supply at once.
Matching these numbers to your real demand is what prevents cold-shower surprises, and it matters more than the logo on the tank.
A storage tank keeps a reserve of hot water ready and costs less to install. A tankless heats water only as you use it, saving energy and space and supplying endless hot water at the right flow rate, with a higher upfront cost.
We install both, plus hot water tank brands and boiler-fired indirect water heater brands.
Water heater performance and safety depend on correct venting, properly sized gas or electrical supply, a working temperature-and-pressure relief valve, an expansion tank where required, and code-compliant connections. Cutting corners here is both inefficient and unsafe.
Our licensed technicians install every unit to code. See our tankless service or request a free estimate.
