In 2015 we were approached by Julia to design and install a new heating system for the renovation project she was undertaking. After our first meeting it was clear that along with a level of ease and convenience a major requirement was for an environmentally friendly solution.
The building itself was quite large although it would be well insulated. After carrying out room by room heat loss calculations, it was clear that a single heat pump would not be able to cope with demand on its own. Therefore it was decided that we would use a hybrid solution utilising a 14kW Mitsubishi air source heat pump and a new condensing Viessmann gas boiler. The air source heat pump would be the primary form of heat. The gas boiler would take over in times of high demand.
For our heat emitters we kept the existing ground floor rooms on the original radiator circuit. Some of the radiators were upgraded with others remaining. The new extension on the ground floor had a standard under floor system installed with a dry screed laid over. On the first floor the master bedroom, walk through dressing area and en-suite again were split into 2 zones. These were constructed from an 18mm cement board overlay system. The remaining bedrooms had a new radiator system installed. There was separate time and temperature control to the ground floor. The towel rails for the bathrooms also having their own separate time and temperature control. Including hot water there is 7 separate zones within the property!
Julia was very keen on solar (both photovoltaic and thermal) and also rain water harvesting. We talked through the available roof spaces and levels of shading and decided that solar thermal would not be suitable for the overall design. However due to the hipped shape of the roof construction, a solar PV array that was triangular shaped would be aesthetically pleasing. We therefore chose the Trienergia range of panels using a mixture of both square and triangular shapes to create the overall effect we were looking for.
A 5,000ltr shallow dig rain water tank was installed into the back garden. All the rain water from the down pipes were rerouted though the tank. All the toilets within the property, washing machine outlet and 4 outside watering points were installed for the rain water system. There is a submersible pump within the tank giving a pressurised supply to each outlet. A manual override is present in case of drought or pump failure.
Additionally we also installed a Charnwood Cove 2 multi-fuel stove. This fitted into a custom built fire place complete with log stores, ornament recesses and a TV recess. There is a pure drinking water filter to all mains cold water outlets within the property and 3 new bathrooms were also fitted.
We would like to say a personal thank you to Julia for tasking energy BY DESIGN with the project. It was such a pleasure to be involved with a large scale transformation of a local property.
