Ecodan Domestic Heating - Case Study
A four bedroom house in Bedfordshire is the first home in the UK to benefit from the new revolutionary Ecodan heat pump. As a result the CO2 emissions from the home's heating system were reduced by 47% and the overall carbon emissions from the property by an impressive 34%.
The homeowner sought to reduce his carbon footprint and by installing Ecodan was able to do so, whilst at the same time, providing an ideal case study for the advanced heating system in operation.
Built in 2000, the four bedroom detached house has double glazed windows as well as loft and wall insulation. The existing heating system was previously run by an 80% efficient gas boiler providing 23.2kW of heat output from an input of 29kW. Based on the existing radiators it was calculated that the total heat output of the radiators was 13.4kW under standard boiler conditions with a flow temperature of 70°C and the hot water demand of the home totals 140 litres per day.
Using the Ecodan heat pump, the heat load of the house was calculated to be 8kW. Operating at a flow temperature of 55°C the heat output of the radiators will be 8.4kW, confirming that Ecodan is fully capable of meeting the heating demand of the house, using the existing radiators. In addition, one area of the house was changed to under floor heating.
The heat load of a house varies with ambient temperature. Traditional systems would vary the output from the radiators by turning them on and off frequently with Thermostatic Radiator Valves (TRV'S), in order to meet the fluctuating demand.
As the ambient temperature increases, the heat load of the house decreases. The highly efficient Ecodan varies radiator heat output by changing the flow temperature, ensuring the highest level of COP possible. With average UK winter temperatures ranging between 2°C and 7°C, Ecodan operates at average flow temperatures between 35°C and 45°C providing the highest levels of energy available.
