Air source heat pumps are an exceptionally clean and efficient source of producing heating and hot water for domestic properties and commercial sites.
An air source heat pump works by extracting readily available heat in the air and local environment through temperatures between -20oC and +35oC, which helps to reduce the dependency on fossil fuels as well as significantly cutting carbon emissions. Air source heat pumps use electricity to operate and run the heat pump. For every 1kW of electricity used, between 3kW and 4kW of thermal energy is available for heating and hot water is available.
GSM Ltd have installed over 900 Mitsubishi Ecodan heat pumps since 2008. We are diamond quality partners enabling us to offer improved warranties and expert backup in the unlikely event that a system fails.
The key to installing heat pumps of any kind is that the heating emitter circuit is optimised to work with heat pumps and run at lower flow temperatures (around 40oC-50oC) than used with a conventional fossil fuel boiler. This means the compressor will have less work to do to convert the low grade heat extracted from the ground into high grade heat needed for heating. The installation as a whole will therefore use less electricity, increasing efficiency and decreasing running costs.
In a domestic retrofit environment we will undertake a careful assessment of the existing radiators and required heat loss of the room. Often radiators were designed using the Mears formula, which significantly oversized the emitters to ensure that rooms could be brought up to temperature quickly when the boiler fired. This oversizing often matches the heat pumps requirements, so generally only the radiators in rooms that are already cold with the existing heating system need up-sizing whilst the rest will work with a heat pump system.
