Tankless water heaters in Salt Lake City, UT

A tankless water heater heats water as it flows, so it doesn't run out, but it needs a larger gas line, its own venting and a unit rated for your elevation. Installed correctly and descaled regularly, it can outlast a tank heater.

Tankless water heaters for Salt Lake City homes

Tankless is popular in remodels because it frees floor space and ends the 'last shower is cold' problem. The catch is the install: most homes need a gas line upgrade, and in mountain states high-altitude derating means a unit has to be sized with your elevation in mind.

Tankless water heaters in Salt Lake City: what's different

Hard water builds scale in tankless heat exchangers in Salt Lake City, so annual descaling is recommended. Hardness varies by neighborhood because water comes from different canyon sources.

Gas tankless units must be set up for the city's elevation, and switching from a tank may need a larger gas line and new venting.

Many Salt Lake homes have finished basements around the utility room, so tankless units are popular because they free up space. Cold winter water means the unit has to be sized for a larger temperature rise than in summer.

Tankless water heaters questions in Salt Lake City

Do tankless heaters need altitude setup in Salt Lake City?

Yes. Gas appliances must be configured for the city's elevation of about 4,200 feet.

Do tankless water heaters work at high altitude?

Yes, if the unit is rated for your elevation or set up for it. Output drops as elevation rises, so a unit sized at sea level may fall short in high-elevation cities such as Denver, Salt Lake City or Albuquerque.

How often should a tankless heater be descaled?

Many manufacturers suggest yearly, more often with harder water. Water hardness varies widely by region (it's high across much of the Southwest, Texas and Florida), so ask your plumber what they see on your water.

Will a tankless heater work with my existing gas line?

Often not. Many tankless units need more gas than the line serving a tank heater can deliver. The plumber checks pipe size, length and the gas meter capacity.
