Water heating
Maintain a heat-pump water heater
Heat-pump water heaters add an air filter, fan, coil and condensate system to the tank. Clear airflow and drainage are essential.
Recommended timingFilter by manual; inspect yearly
What to do
- Clean the air filter on the schedule in the owner manual and whenever the unit displays a filter alert; DOE notes this filter needs regular cleaning.
- Keep required air clearances open and do not crowd the unit with storage or corrosive products.
- Confirm the condensate line and drain remain clear and look for water around both the tank and condensate system.
- Follow the tank manufacturer's anode and sediment guidance, recognizing that some models use different corrosion-protection designs.
- Have refrigeration, electrical, fan, coil, condensate or persistent error-code concerns serviced by a qualified technician.
Do not open refrigeration or electrical compartments. Follow the exact manual before cleaning near the coil, fan or energized equipment.
