WATERSTAGE™ ATW Systems Is it all right to install an ATW system in a cold region?

Answer
No problem at all. There is no low-temperature operational limit on an ATW system. The heat pump operates at subzero temperatures. When the heat pump alone cannot meet the peak heating requirements of a house, an electrical backup heater kicks in to provide additional heating.
