5 *3 Based on PUZ-SHW80VAA model under nominal heating conditions at outdoor temp: 7°CDB / 6°CWB, outlet water temp 35°C, inlet water temp 30°C as tested to EN14511. *4 Based on manufacturer information for gas instant hot water heater (non-condensing). Electric element heating assumed 1 to 1 efficiency. How Efficient is a Hot Water Heat Pump? The efficiency of a heat pump is known as the Coefficient of Performance or COP. This is a ratio of the heat delivered to power consumed. As an example, in winter conditions the PUZ-SHWM80VAA Ecodan can consume 1.19kW of electrical energy and deliver up to 6kW*3 of heat energy by absorbing freely available heat energy from the air, heating your home and hot water with an environmentally friendly option compared to gas and diesel boilers. Compared to typical gas and direct electric heating systems that can have higher running costs with inefficient COPs as low as 0.80*4, Ecodan Hot Water Heat Pumps provide a real energy efficient alternative. Ecodan’s COP of 5.05*3 means for every 1.19kW of electricity input, you can get up to 6kW of heat output by absorbing free heat energy from the outdoor air. 0.80 1.00 5.05 4.81kW Low temperature renewable heat energy taken from the environment 1.19kW Electrical energy output Up to 6.00kW heat energy output Gas Heating (Non-Condensing)*4 Electric Heating Ecodan COP Comparison Chart “Eco-friendly heating for your home, helping to reduce carbon emissions.”
