How we work out heating

How we design a heating system.

  1. Step 01

    Survey the house

    We measure each room and record the walls, windows, loft and floor insulation and ventilation, along with your existing radiators and pipework.

  2. Step 02

    Work out the heat loss

    Each room gets its own heat loss figure. Added together, they tell us what the system has to deliver on the coldest days.

  3. Step 03

    Design the system

    We do the heating design ourselves: flow temperature, radiators, pipe sizes, hot water cylinder and controls. If a radiator needs to change, we'll show you which one and why before you decide.

  4. Step 04

    Install and hand over

    The system is set up to the design, and we take you through the controls before we leave.

What the survey covers

  • Every room measured
  • Walls, windows and insulation recorded
  • Ventilation checked
  • Existing radiators and pipework assessed
  • How you use your heating and hot water

What you get at handover

  • A system sized to your house's heat loss
  • Radiators checked against the design and changed only where needed
  • The system set up to the design
  • A walk through the controls
  • A tidy house, with dust sheets down throughout the job

Reviews

What our customers say

  • High quality work for a highly competitive price.

    Kenneth
  • Allan & Gary installed our heat pump in April and I could not be happier with their work and knowledge. The workmanship was excellent, they kept all work areas clean and tidy. Changing from a Gas Boiler to Heat Pump can seem daunting but they would answer any question or queries I had on the system to ensure I knew how to operate it going forward and gave me confidence I was doing the right thing. Highly recommended company.
