In this episode we commission 2 air source heat pump installations and link up the Solar PV Diverters to generate some of the hot water as opposed o sending energy back to the grid.
We also show you how to install the Mixergy PV Switch.
We have installed Mixergy Smart Hot Water cylinders along side Mitsubishi Ecodan. We also ask the question 'Do you need to treat the system with Glycol/Antifreeze?'
No not necessarily if you install the Caleffi Anti Freeze Valve. The valve will release the water in the primaries in the event of a system failure in very cold winters. If the water temperature reaches 3 degrees or below, the valve activate, releasing the water to prevent damage to the pipework and more importantly the heat pumps Plate Heat Exchanger.
