Efficiency upgrade
Weather compensation controls for Somerset heating systems
Weather compensation drops your boiler's flow temperature on milder days so it condenses more efficiently and the house heats more gently. On a modern condensing boiler it's the single cheapest efficiency upgrade you can make.
For: Homeowners with a modern condensing boiler
When it makes sense
Best on a system boiler with well-sized radiators or underfloor. On a combi with tiny old radiators it helps less. We check emitter output before quoting so we don't sell an upgrade that won't deliver.
What we install
- Outdoor sensor sited on a shaded north wall
- Wiring back to the boiler's low-voltage compensation input
- Curve configured to your home's heat-loss profile
- Follow-up review after two cold weeks
- Documented flow-temp/OAT curve in your service file
Frequently asked
- How much does it save?
- Real-world 5–12% on gas, depending on how oversized the boiler was in the first place. Bigger boilers with smaller loads save more.
- Does it work with a smart thermostat too?
- Yes — you can have both. Weather compensation controls the flow temperature; the thermostat controls when it's on.
- Which boilers support it?
- Most modern Vaillant, Worcester Greenstar and Ideal Vogue models. We check the exact model before quoting.
