The Tempra 24 electric tankless water heater will be able to run an average shower head in most climates. This electric tankless water heater could supply all of your domestic hot water if you have relatively low demand (i.e. 1 bathroom, 2 or less residents). This heater will not be able to run more than a shower head at one time, though it should be able to run two sinks (bathroom or kitchen) at the same time.

Provides up to 4.10 gallons per minute(40 degree temp rise) for water usage at 105° F: 2 sinks or 1 shower. The Tempra™ has several advantages over a gas-type tankless water heater. Compared to many similar gas tankless models the Tempra™ is less expensive to purchase. Installation is also much simpler and cheaper since it is not necessary to vent a Tempra™ to the outside. The venting that a gas unit requires causes anywhere from a 10 20% efficiency reduction from heat escaping out the exhaust pipe.

Furthermore, for every cubic foot of gas burned, two cubic feet of air have to be mixed in to create ideal combustion. In a cold climate, this hurts efficiency further. When a gas unit fires, it draws in air around it, heats the water, and then expels warm exhaust outside. Since no house is airtight, this suction action causes a drafting condition where cold air from the outside seeps back in through door cracks and other parts of the house that may not be airtight. By nature of the design, the Tempra™ is nearly 100% efficient; converting 100% of the electrical energy it consumes into heat. All that heat is then transferred to the water none is lost to the outdoors.
