Should I Get a Tank or Tankless Water Heater?

A tank is cheaper to put in and simple to replace like for like. A tankless unit takes less space, doesn't run out during long showers and usually lasts longer, but costs more up front and may need gas or electrical upgrades.

How do tanks work?

A tank keeps 40 to 50 gallons or more hot all day. When it's used up, you wait for it to reheat.

How does tankless work?

It heats water only as it flows. The limit is how many showers and appliances can run at once, not how long.

What about gas lines and venting?

Gas tankless units often need a bigger gas line and new venting. Electric tankless units can need a large electrical supply. The plumber will check before quoting.

Where does it go?

Many Tyler homes have the heater in the garage or attic. Tankless units hang on a wall, freeing floor space. Attic units of any kind need a drain pan.

What upkeep does each need?

Tanks benefit from a yearly flush to clear sediment. Tankless units need regular descaling, more often where water is hard.

Which suits my house?

Families who run out of hot water often like tankless. If your tank is failing and you want a quick, simple swap, a new tank is fine. See water heaters.

What about cost over time?

Tankless units use energy only when water runs, which can lower bills for some households. Whether it pays back depends on how much hot water you use and what the install costs. Ask for both options in the quote.
