Frequently asked questions

How long does a water heater installation take in Delaware?

A like-for-like tank swap takes 2–3 hours. A tankless conversion in Delaware usually takes most of a day because we run new venting and often upsize the gas line.

Is a tankless water heater worth it?

For most Delaware families of three or more, yes: endless hot water and 20+ year lifespan. For a small household, a high-efficiency tank is often the better value. We give you both prices.

Do you install the brand I already have?

We install and warranty all major brands: Rheem, Bradford White, A.O. Smith, Navien, Rinnai and Noritz.
