Vaillant Heat Pump, Chingford E4
A renovation in Chingford E4 where the survey showed a smaller Vaillant heat pump would do the job properly. So a smaller one is what went in.

A heat pump sized to the house, not rounded up, in Chingford
We replaced an old gas boiler in Chingford E4 with a smaller-capacity Vaillant aroTHERM plus air source heat pump, sized to the home's actual heating and hot water demand, during a wider renovation. Three days on site, with the £7,500 grant taken off. Rounding a heat pump up to be safe is a common mistake. An oversized unit costs more to buy and runs less efficiently.
The heat loss survey showed the house did not need a larger unit, so a smaller one was fitted. It runs in longer, steadier cycles, which is quieter and more efficient than a big unit starting and stopping.
The unit stands on blocks against the house wall, clear of the ground, with a short pipe run inside.
