Roof-Mounted Heat Pump, Islington N1
An Islington N1 home with no garden space to spare. The 7kW Vaillant aroTHERM plus went up onto the flat roof instead, with the £7,500 grant taken off the price.

No room in the garden, so the heat pump went on the roof
We installed a 7kW Vaillant aroTHERM plus air source heat pump on the flat roof of a home in Islington N1, because the garden had no space for it. It now provides the house's heating and hot water, with the £7,500 grant taken off the price. Inner London gardens are often too small for a heat pump. A flat roof is frequently the better place, provided the roof is protected and the unit can be reached for servicing.
The garden was too small to give a unit the clear space it needs round it without taking over the garden. The flat roof had the space and the free air a heat pump wants. The unit stands on rubber blocks over a protective mat, so its weight is spread and the roof covering is never pressed by a sharp foot. Nothing is fixed through the roof.
A heat pump is serviced every year, so the position has to be one an engineer can get to safely. That was checked at the survey before the roof was chosen.

Thinking about a heat pump in Islington?
We measure every room, calculate the heat loss, check the radiators and the space for a cylinder, and send a written price with the grant already taken off. No cost and no obligation.
