-
Do I need tankless water heater maintenance?Tankless systems need maintenance just like any other kind. Heating elements can burn out, components can fail and piping or tanks can spring leaks. Routine tankless water heater maintenance will also be key to extending the life of your unit.
-
Why does the water go cold sometimes?Water shouldn’t go cold with a tankless system unless something is wrong with the equipment or there is too much simultaneous demand for hot water for the unit’s output capacity.
-
Does hard water matter?Tankless systems are less vulnerable to the effects of containing hard water because it doesn’t sit in a holding tank. However, the mineral scale can still build up inside any of the plumbing fixtures involved over long periods of time.
