Boilers & Heating
Boiler replacement, controls and zoned heating upgrades.
The boiler is the heart of the heating system. Replacing an aged or inefficient boiler with a modern condensing combi or system unit cuts bills, improves reliability and unlocks zoned controls, smart thermostats and underfloor heating integration.
Common Damage
1. No Heating or Hot Water
- Failed pump, diverter valve or PCB
- Low system pressure or air locks
- Pilot or ignition faults on older units
2. Inefficiency
- Older non-condensing boilers waste energy
- Higher bills than necessary for the property size
- Frequent cycling on and off
3. Leaks & Corrosion
- Drips around the boiler casing
- Sludge in radiators reducing output
- Internal corrosion shortening lifespan
Repairs
minor Repairs
- Re-pressurise system and bleed radiators
- Replace thermostats and timers
- Service annually for safety and efficiency
moderate Repairs
- Replace failed pumps, valves or expansion vessels
- Power-flush system to remove sludge
- Add magnetic system filter

- Integrate underfloor heating with new manifolds
New Installation
When Replacement Is Needed
