5 1kW Electrical energy input 3.2kW Heat energy output 2.2kW Low temperature renewable heat energy taken from the environment 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. For every 1kW of electrical input energy, Ecodan absorbs freely available heat energy from the outdoor air to provide the home with an average of 3.2kW*3 of heat output. 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. “Now you can enjoy hot water responsibly all year round!” *3 A s independently tested by BSRIA based upon BSEN14511 Part 3 standard rating conditions. Due to the method of operation, the performance of heat pumps will vary based upon the temperature of the heat source and the requirements of the heat delivered. The BSEN14511 testing relates to the heat pump performance only and not the entire heating system. *4 Based on manufacturer information for gas instant hot water heater (non-condensing).
