The Dimplex range of air source heat pumps is popular with specifiers, consultants and developers, with a new range of high efficiency models extending the range to meet the demand for energy efficient heating and hot water in both commercial and residential builds, including multi-dwelling developments.
Air source heat pumps have the most straightforward installation requirements of all the heat pump technologies and the units are able to extract renewable heat from the freely-available outside air, even at low temperatures (down to -25ºC).
The new range of high efficiency models is available in a choice of five outputs from 9 – 40kW, all offering Coefficients of Performance (CoP) comparable with ground source units. The largest in the range, the LA 40 TU, offers a flow temperature up to 58ºC, although optimum performance is achieved at lower flow temperatures; 3.9 at A2/W35 and 4.5 at A7/W35.
The range is ideal for applications including communal systems for apartment developments and commercial buildings. For buildings with higher heating loads, several heat pumps can be used in parallel.
