A heat pump with the indoor kit in the loft, in Hornsey

We replaced an ageing gas boiler in Hornsey N8 with a Vaillant aroTHERM plus air source heat pump running the underfloor heating and hot water, with the indoor equipment in the loft so none of it takes up living space. Three days on site, with the £7,500 grant taken off. Where the indoor kit goes is a choice, not a fixed rule. A loft works when it is boarded, reachable and protected from frost.

The owner did not want a cylinder cupboard in the house, so the indoor equipment went into the loft. The layout was planned at the survey so the pipe routes up to it are short and hidden. The outdoor unit has its own base in the garden, level and clear of the ground, with the pipework taken to the house in one run.

Underfloor heating runs at lower water temperatures than radiators, which is exactly where a heat pump is at its most efficient.
