McDonald Engineers join the Heat Pump Association.

McDonald Engineers manufacture their POWERflow 2000 Unvented Mains Pressure System in Copper. This allows a highly efficient copper coil to be fitted which is ideally suited to take advantage of input from heat pumps. Unlike other materials, Copper transfers the heat extremely efficiently. While this is a general benefit of copper units, it is even more important with the lower flow temperature delivered by heat pumps.
