Fan coil being installed in garden room to replace UFH, which really didn't work well unless at flow temperatures. Which wasn't an option with the ASHP and the main house heating demand. So Christmas eBay search led to me buying a Myson iVector MkII fan coil 1.2m wide. This unit can do heating and cooling and has a variable fan cut in temperature, so should allow me run weather compensation. Unfortunately the unit needs to placed on the opposite side of the summer house to the existing water entry point. So instead of running pipes internal, have decided to run them externally. Some photos of progress Unit wall mounted Cover installed The unit I got is a 4 pipe fan coil. This unit has a dedicated cooling and seperate heating heat exchangers. The heat transfer area of the combined heating and cooling HE's is about 50% larger than a 2 pipe fan coil. Have piped the two HE's as a single unit. I am using a Salus self balancing actuator to balance the flow rate through the fan coil. Have started the external piping using 15mm Hep2O and 25mm wall thickness insulation. The insulation to aluminium tape covered to keep mice away and UV to stop sun damage. The pipes sit on metal brackets 40mm off the ground and are galvanised banded into place.
