Heating the house or providing domestic hot water? Most water heaters are not "listed" for space heating and many local jurisdictions specifically restrict domestic water heaters from being used as boilers in space heating installations.

To the point of your question; the "reset" is in actuality a "manual reset high temperature shut down switch" and is a safety device. I don't off hand remember the setting (non-adjustable) where they trip (shutting off all power to the heater elements) but they should not be tripping under any kind of "normal" condition. When they do it indicates that either one of the element thermostats is not functioning properly or sometimes the element itself is "grounded" (defective) and constantly using power to heat the water regardless of the thermostat operation.

Do you want to troubleshoot this yourself? You will need a simple multimeter to do so.
