The buffer tank is designed to be incorporated into a space heating circuit, increasing the volume of water in the heating system. This additional water volume is intended to protect the heat pump compressor from short cycling which can lead to higher running costs, damage to the heat pump, a reduction in its working life and lower energy efficiency performance. Additionally, it helps protect the heat pump by assisting defrost cycles and improves the heating system response times.
Suitable for the primary heating circuit of both open vented or sealed system (6 Bar maximum pressure)
Improved comfort levels as heating system can be fully controlled and zoned
Reduces or eliminates short cycling of the heat pump
Prevents water in the system from getting colder during heat pump defrost cycles
Future-proofs the heat pump system for smart electricity meters with flexible energy tariffs
Manufactured from SUS 304/ SUS316L stainless steel for superior corrosion resistance
50mm thickness of environmentally-friendly foam lagging for low standing heat loss
