If the high-limit temperature setting is too high, generally over 200 degrees Fahrenheit, the system pressure will reach an excess condition as well and start leaking.

Considerations - Heat Pump Water Heaters (HPWHs

2 Because the cool air from the HPWH will force your heating system to work harder, paybacks for the HPWHs will be longer in colder climates if installed in conditioned space. In very warm climates, the benefits to the cooling system working less hard will lead to shorter paybacks. 3 These two heating modes is why sometimes HPWHs are referred to as "hybrids".
