High Efficiency Tank Water Heaters
Modern tank water heaters are incredibly reliable and highly efficient water heating systems. They are more economical for smaller homes with less demand. There are two major kinds of tank water heaters: High Efficiency Conventional Tank and Heat Pump Water Heaters (HPWH).
Conventional High Efficiency Water Heaters
Conventional storage water heater fuel sources include natural gas, propane, fuel oil, and electricity. All conventional water heaters store hot water 24 hours per day in a storage tank, typically ranging in volume from 20 to 120 gallons.
To minimize stand-by losses you should consider water heaters that offer higher levels of tank insulations. Often the lowest-priced storage water heater may be the most expensive to operate and maintain over its lifetime.
High efficiency conventional water heaters keep up with demand giving you seemingly endless hot water for bathing, cooking, dishes, laundry, and all the other countless ways hot water enriches our lives. We carry a wide variety of gas tank water heaters. They are often the lowest installed cost choice for replacing an existing system.
Het Pump Water Heaters
Heat pump water heaters (HPWH) can be two to three times more energy efficient than conventional electric resistance water heaters.
HPWH use electricity to move heat from one place to another instead of generating heat directly. To move the heat, heat pumps work like a refrigerator in reverse.
While a refrigerator pulls heat from inside a box and dumps it into the surrounding room, a stand-alone air source water heater pulls heat from the surrounding air and dumps it - at a higher temperature - into a tank to heat water.
We carry stand-alone heat pump water heating systems from several manufacturers. They are all integrated units with a built-in water storage tank and backup resistance heating elements.
Heat pump water heaters should be installed in locations that remain in the 40°-90°F range year-round and provide at least 1,000 cubic feet of air space around the water heater. Cool exhaust air can be exhausted to the room or outdoors.
A great choice is to install them in spaces with excess heat, such as a furnace rooms. HPWH tend to cool the spaces they are in so you can benefit from free air conditioning in the summer as you are heating hot water.
