Weather compensation can make your heating system far more efficient, but only when it is set up correctly. Many homeowners in places such as Bordon, Whitehill, Liphook, Alton and Farnham find that winter comfort improves dramatically once the boiler’s weather compensation curve and thermostat schedules are properly aligned. This guide explains how to manage a boiler weather compensation reset and fine‑tune your settings for consistent warmth through UK winters.
Quick checks you can do now
- Confirm your thermostat is set to the correct mode (heat, auto, schedule).
- Ensure the outside temperature sensor is not obstructed.
- Check that radiators are warming evenly.
- Look for any recent changes to schedules or temperature set points.
What weather compensation actually does
Weather compensation automatically adjusts your boiler’s flow temperature depending on the outside temperature. When it’s mild, your boiler runs at a lower flow temperature; when it gets colder, the temperature increases. This improves efficiency and reduces gas usage for homes across GU35, GU34 and GU9 areas.
If your home feels too warm, too cool, or slow to heat, your compensation curve or connected thermostat schedules may need attention.
When you might need a boiler weather compensation reset
A reset helps recalibrate the system when settings have drifted or become mismatched. Common situations include:
- Recent thermostat or controls update.
- Outside sensor replacements.
- Boiler servicing or power interruption.
- Sudden changes in indoor comfort, especially during early winter.
Before adjusting curves, ensure your thermostat schedule is reasonable—many comfort issues come from mismatched timing rather than boiler faults.
Step-by-step: Carrying out a boiler weather compensation reset
The exact steps vary by boiler model, but the principles are broadly the same.
- 1. Locate the weather compensation settings. This may be on the boiler menu or within an attached controller.
- 2. Note your current curve. Write it down so you can revert if needed.
- 3. Select reset or default curve. Most systems have a factory baseline that provides a good starting point.
- 4. Restart the heating. Allow at least one full heat cycle to evaluate behaviour.
After the reset, your system should respond more predictably to drops in outside temperature.
Optimising the heating curve after a reset
Once the reset is complete, you can optimise comfort by fine‑tuning the curve. This involves adjusting the boiler’s flow temperature response. A lower curve saves energy but may heat the home more slowly. A higher curve increases comfort but may reduce efficiency.
- If the house is warm enough but slow to recover from temperature drops, increase the curve slightly.
- If the boiler cycles frequently or the house overheats, reduce the curve.
- Make only small adjustments—one change per day is usually enough.
Homes in Bordon and surrounding areas often benefit from a mid‑range curve due to typical local winter temperatures, but every property is different.
Setting and syncing connected thermostat schedules
A boiler weather compensation reset is only fully effective when paired with sensible thermostat scheduling. Your connected thermostat should avoid dramatic temperature swings. Aim for steady adjustments that allow the boiler to work efficiently.
- Set daytime temperature at a comfortable level, typically around 19–20°C.
- Use a mild night setback—usually no more than 2–3°C.
- Avoid frequent on/off cycles; use gradual temperature changes instead.
- Ensure holiday or away modes are disabled when you return home.
Make sure your thermostat app matches the settings on the physical device; mismatches are a common cause of heating issues.
Troubleshooting common winter heating issues
- Radiators slow to heat: Curve may be too low or schedule too restricted.
- Home feels stuffy or too warm: Curve may be too high.
- Boiler cycling frequently: Check both compensation settings and thermostat setback levels.
- Unexpected temperature drops: Review schedule segments for gaps or incorrect temperature targets.
Simple checklist before calling an engineer
- Has the boiler weather compensation reset been completed correctly?
- Are thermostat schedules aligned with actual household routines?
- Is the outside sensor exposed and functioning normally?
- Have you allowed the system one full heating cycle after adjustments?
When to seek professional help
If your boiler continues struggling after curve adjustments and schedule checks, a Gas Safe engineer can review sensor placement, boiler operation and system balancing. Properties in Bordon, Whitehill and nearby towns sometimes experience unique heat‑loss patterns due to local building styles, so a professional assessment can be useful.
