How do I maintain my Thermor heat pump water heater?

Thermor recommends three essential maintenance steps: operate the pressure relief valve monthly to prevent jamming from scale deposits, drain the tank at least every two years in hard water areas to remove mineral buildup from the heating element, and inspect electrical connections and thermostats for proper functioning.

What is Thermor's ACI Hybrid anti-corrosion protection?

ACI Hybrid (Anti-Corrosion Integrated) is Thermor's patented system combining an indestructible titanium anode with magnesium particles. An electronic control board produces a low-intensity electrical current that uses naturally present minerals to protect the tank's enamelled walls from corrosion.

What is Frost Protection mode and when should I use it?

Frost Protection (also called HG or Hors Gel) maintains the room temperature at approximately 7°C to prevent freezing. Use this mode when you are away from your home for more than 48 hours during cold weather.

What is Eco+ technology on Thermor smart water heaters?

Eco+ is Thermor's intelligent learning system that analyses your domestic hot water usage habits and consumption patterns. It automatically adjusts water heater operation based on detected routines, delivering up to 10% energy savings without sacrificing comfort.

What should I do with my heat pump water heater during an extended absence?

For absences of less than two months, close the water inlet valve at the safety group. For absences longer than two months, close the water inlet, drain the tank completely, and ideally allow it to dry out. This prevents stagnant water issues and protects the system during extended periods without use.
