A live trial of a Mitsubishi Ecodan air source heat pump feeding nine Jaga Strada DBE radiators at a 1950’s, 4-bedroomed house in Berkhamsted in Hertfordshire has demonstrated that the system was still achieving over 300 percent efficiency levels (a COP of 3.0 – Coefficient of Performance) ) throughout December 2010, when the country faced long periods of sub-zero temperatures not seen for decades.
Strada DBE radiators offer maximum efficiency at low water temperatures and also contain around 15 percent of the water normally held in a traditional radiator. This means that there is less water in the entire system that needs to be heated before the effects are felt within the room and allows the Strada DBE to deliver the heat needed more quickly.
According to Mitsubishi Electric's Jason Tinsley who is Technical Manager for Ecodan: “Intelligent radiators like these use microprocessors to monitor the surrounding conditions in ways that traditional ones simply can’t and they will react to outdoor temperatures much more quickly, reducing the heat output if necessary or raising or lowering the flow temperature as required. This gives the homeowner much better control of the overall energy use."
