Boiler installation in Gloucestershire is one of the most impactful home improvements for energy savings. In Avening, we survey your existing system, calculate your hot water demand, and recommend the right boiler type and size — not the most expensive one, the right one for your home.

Combis save space and provide instant hot water, but they can struggle in homes with multiple bathrooms running simultaneously. We assess your usage patterns and recommend accordingly.

the Severn Vale gets damp winters with heavy rainfall. Bathrooms need good ventilation and proper waterproofing — condensation on cold stone walls is a particular issue in older properties. water is moderately hard in most of Gloucestershire (150-250 mg/l calcium carbonate). Limescale builds up on shower heads, taps, and heating elements — thermostatic valves and easy-clean coated shower glass help manage this.
Choosing the right boiler size for your Avening home depends on the number of bathrooms and radiators. A 24kW combi suits a small Gloucestershire flat with one bathroom. A 3-bed semi in Avening with a family bathroom and en-suite needs 30-35kW. We calculate the exact requirement rather than guessing.
