A tankless water heater performs quite well during this time, even with some restrictions. These water heaters make great use of a condenser that pre-warms the H2O, so it takes little time to reach the pre-set temperatures for using. Typically, the water reaches temperatures set by the home owner at a rate of 1.5 gallons per minute. When this process begins, the water may flow with little pressure so the heater has time to heat the water, but when it reaches the destination the water is as hot as desired.
Contrary to what people believe, the hot water temperatures created by the tankless water heater are not held back by the temperatures outside. However, it is important to take into consideration that tankless water heaters can freeze if the proper precautions are not taken when the temperature outside drops below a certain degree.
Maintenance Is Key
Most indoor and outdoor tankless water heaters include a built in freeze protection against certain temperature levels ranging from -7 degrees to -21 degrees Fahrenheit. This protection has its limits and cannot resist temperatures below freezing for extended periods of time. To avoid complications with a tankless water heater, there are a few steps that should be taken.
The first step in winterizing a tankless water heater is to turn the unit off and unplug the power source. Next step, turn the water supply off and drain all water from the heater. Disconnect the water pipes from the heater to minimize the water pressure. Place the proper cover over the vent termination for intake to hold the debris out.
After this has been accomplished, when setting up a dual vent system or concentric system face the vents away from the wind to prevent anything from freezing. Locate the areas that are not subject to freezing and set up the drain pipes in that location. Implement plenty combustion air for gas powered parts to prevent negative draft from any freezing water within a tankless unit.
Aside from this, running a small stream of hot water continuously can avoid freezing.
