When you need tankless water heater services, call HEP, Inc. to get it fixed right the first time!

It is believed that tankless water heaters are more efficient than tank water heaters. This is because storage water heaters lose a lot of heat when they are on standby and when they re-heat the water, they increase utility costs. The energy is wasted while maintaining the water temperature at a certain level. Tankless heaters only heat the water when needed, thereby saving energy costs when no one is in the house.


A big difference between tankless water heaters vs. regular water heaters is that a tankless will heat the water directly, while a storage water heater does not. If you turn on the shower upstairs, cold water travels through a pipe to the tankless heater. Then, either a gas burner or an electric element heats the water, delivering a constant supply of hot water for however long that shower occurs. This eliminates concerns about running out of hot water while you wait for the storage tank to refill with hot water.

Smart Tankless Water Heaters

HEP, Inc. also offers tankless water heaters that can connect to your smartphone, and you can control the tankless water heater from the comfort of your couch in seconds. This tankless water heater has a digital screen on it so that you can easily adjust the thermostat to your desired temperature. Our certified technicians can program the tankless water heater for you, so it is as easy as tapping a button!

For homes that use 40 gallons or less of hot water daily, tankless water heaters can be 24%–34% more energy efficient than conventional storage tank water heaters. They can be 8%–14% more energy efficient for homes that use a lot of hot water- around 86 gallons per day. In some cases, you may be able to achieve even greater energy savings if you install a tankless water heater at each hot water outlet. It is also believed that a tankless water heater can increase your home’s value.

The initial cost of a tankless water heater is greater than that of a conventional storage water heater, but tankless water heaters will typically last longer and have lower operating and energy costs, which could offset their higher purchase price. Most tankless water heaters have a life expectancy of more than 20 years. They also have easily replaceable parts that may extend their life by many more years. In contrast, storage water heaters last 10–15 years.
