Ground Sun installed the Ochsner GMLW 14 Plus Air Source Heat Pump for this retrofit project in Woodford Green Essex
The Ochsner GMLW series are highly efficient horizontal-split heat pumps comprising an outdoor air heat exchanger unit connected to the heat pump which is located inside the property. It is extremely quiet and boasts a coefficient of performance (COP) of 4.4 at air 2C and 5 at air 7C….where most other companies cant get close to these certified efficencies
Ground Sun rennovated the entire house with a helical screw pile foundation and Structural Insulated Panel (SIP) extension side and rear, improved insulation throughout the property, high performance double glazing and underfloor heating with polished concrete flooring. We were origionally contacted for the piles, structure and heat pump only, we get asked all the time if we would do the whole build and finish …. and normally/ always say no. But the job was local and the client was great so we agreed to proceed with the extra work internal finishes, loft conversions,plumbing,electrical and overall main contractor duties on this project. The end result is a happy client with a property that was extended circa 40% whilst its EPC was improved from a D to a B (and not far off a A) for this solid wall older type property.
