Heating 7 min read23 February 2026

Installing a complete central heating system is the biggest single job most homeowners commission from a heating company. Knowing the sequence removes most of the stress.
Survey and heat loss calculation
Every radiator is sized from a room-by-room heat loss calculation, not guesswork. Older Glasgow sandstone properties lose far more heat per square metre than a modern Cumbernauld estate house, and the radiator schedule has to reflect that.
The installation sequence
A typical three-bedroom install runs like this:
- Day one: floors lifted where needed, pipework routed, old system drained and stripped
- Day two: radiators hung, boiler mounted, flue and condensate run
- Day three: system filled, cleaned, inhibitor dosed, controls wired and commissioned
- Handover: balancing, thermostat setup, paperwork and warranty registration
Controls and zoning
Scottish building standards push for proper zoning and time control. We fit TRVs throughout, separate heating and hot water control, and offer smart controls that let you heat the rooms you use rather than the whole house.
Need help with this?
We handle this work every week. See Heating & Boiler Services in Glasgow or browse all our services.
Frequently asked questions
How long does a full installation take?
Two to four days for a typical family home, depending on the number of radiators and pipe routes.
Will you lift my flooring?
Only where necessary, and we agree routes with you first. Boards are refitted carefully.
Can I stay in the house?
Yes. Heating and hot water are off for part of the work, and we tell you exactly when.
