Types of water heaters
and which fits your home.

Tank, tankless or heat pump? Compare how each one fits your current setup, how much hot water you use and your budget.

Gas tank

The usual choice if you already have gas. The new tank has to work with your existing vent.

Electric tank

The simplest swap if your heater is electric now. Also get a price on a heat pump model, which costs less to run.

Heat-pump tank

Uses much less electricity. Needs room for airflow and a drain, makes a low hum and can reheat more slowly.

Tankless

Heats water as you use it. Size it for how many taps run at once and how cold your water comes in.

What to ask about each type of water heater
Type	Ask the installer about	Also check
Gas tank	Your current gas line and vent	The right model for your vent, and enough air for the burner
Electric tank	Tank size, and how much hot water it delivers in the first hour	How its running cost compares with a heat pump
Heat pump tank	Room size, location and which mode to run it in	A drain for the water it makes, noise, and changes to the space
Gas / electric tankless	How much hot water it delivers when your incoming water is cold	Whether your gas line or electrical panel can handle it, and regular descaling

Each linked guide lists its manufacturer and ENERGY STAR sources. These questions help you choose. They don’t replace an installer’s plan for your home.
