CALEFFI iSTOP 1" heat pump protection kit

The iStop® heat pump protection kit for monoblock type is a convenient package of devices essential for heat pump installation:

• Filling valve - maintains pressure in the heating system at a constant required level by automatically replenishing water losses in the system,
• Dirt separator - captures mechanical impurities, including fine ferromagnetic particles, which, when deposited in the system, reduce heating efficiency, block flow in heat exchangers, pumps, and control valves.
• Anti-freeze valves are an innovative solution developed by Caleffi, which is the "last resort" protecting the heat pump from damage in case of power failure during freezing.
