Mr and Mrs J

Mr and Mrs J from Somerset sought to replace their aging oil‑fired boiler with a low‑carbon, highly efficient heating system. Their goals were:

Following a detailed heat‑loss assessment, a 10 kW Midea M‑Thermal Arctic R290 A+++ air source heat pump paired with a 250‑litre domestic hot water cylinder was selected as the optimal solution.

A room‑by‑room heat‑loss calculation confirmed a peak heat demand of 8.4 kW, making the 10 kW Midea unit ideal, with capacity for extreme cold conditions.
