Coefficient of Performance

The Coefficient of Performance (COP) is a measure of the effectiveness of a boiler in converting the fuel it uses into heat. It is a simple ratio of energy in, to energy out. In all conventional boilers the COP is less than 1 i.e. they consume more kW h of electricity, oil or gas than they produce in heat. The most efficient combi boilers can approach a COP of 0.9 or 90% efficiency.

The Eco Air Boiler heat pump produces a COP of up to 4 or 400%, thus as much as 4 kW h of heat can be produced from 1 kW h of electricity, this is high performance, renewable micro generation.

The COP of a heat pump varies with the outside temperature. During the no obligation initial consultancy Global Energy Systems will assess the energy efficiency of your property, the heat delivery methods that you have or propose, and the size of your property, to design a system suitable for your requirements in even the most extreme weather. Eco Air Boilers delivered renewable heat energy effectively throughout the winter of 2009/10.

To demonstrate the seasonal variation that temperatures can have the following chart shows the COPs attainable with Global Energy Systems' Eco Air Boilers.

This assumes a steady flow temperature of 35°C, sufficient to hold a room temperature of 21°C in a reasonably insulated property, and are based on independent testing.

Not all heat pumps are created equal. Many start life as air conditioning units designed to work in the summer months. Many are also designed for office buildings where noise is not an issue. Many are designed to rely on expensive to run, electric immersion heaters on a day to day basis.

Global Energy Systems' Eco Air Boilers are not designed that way.

Designed from the outset as a complete central heating and domestic hot water system, in the UK and for UK, the Eco Air Boiler is a robust, 365 day a year high performance system. The compressor, evaporator, heat exchanger and even the refrigerant are engineered to offer year round performance in a UK climate.

Designed to offer domestic hot water up to 70°c down to air temperatures as low at -25°c the Eco Air Boiler has no need for immersion heaters to supply year round hot water. It can work with power showers and standard radiators through the deepest of winters.

As an MCS accredited manufacturer and installer of our own heat pumps, Global Energy Systems can provide a full assessment, specification and installation service, ensuring that your renewable energy solution is tailored to your needs.
