Understanding the Challenges of Heating Older Period Homes
Older period properties around Odiham often charm us with character features like sash windows, high ceilings and solid walls. Yet these same elements can present real heating challenges. Many thermal improvements applied to modern houses aren’t straightforward in period homes. Thick masonry walls, original joinery and heritage restrictions mean poor insulation, draughts and uneven heat distribution are common issues.
Whether you live in Odiham or nearby Bordon (GU35), Alton (GU32), Liphook (GU30) or Farnham, a tailored approach is key. Here’s how to optimise energy efficiency and warmth without compromising period integrity.
1. Fabric and Insulation Upgrades
Roof and Loft Insulation
The roof is the biggest source of heat loss in any home. In period properties, loft spaces may have basic insulation or none at all. Adding at least 270mm of mineral wool or rigid boards can cut heat loss by up to 25%. Ensure any ventilation runs remain clear to avoid damp.
Floor Insulation
Solid or suspended timber floors in older homes can be draughty and cold underfoot. Options include:
- Rigid or PIR boards laid over the floor structure
- Loft-style insulation between suspended joists with breathable membranes
- Underfloor heating panels suitable for period floors (low-profile systems)
Wall Insulation Options
Solid brick or stone walls can’t accept cavity fill. Consider:
- Internal wall insulation (IWI): insulated plasterboard and vapour control layers
- External wall insulation (EWI): renders or cladding systems that respect the aesthetic
- Injection foam for hidden voids, though often less effective on heritage walls
2. Draught-Proofing Windows and Doors
Sash and casement windows add period charm but are notorious for draughts. Before replacing with double glazing, try more sympathetic measures:
- Secondary glazing panels that sit behind original frames
- Brush or rubber draught excluders along sashes
- Thick thermal curtains hung close to the window reveals
- Weatherstripping and letterbox brushes on external doors
3. Upgrading Your Heating System
Modern Boiler Solutions
Older boilers struggle to heat large period rooms efficiently. Consider replacing any pre-2005 model with a modern condensing combi or system boiler. Benefits include:
- Higher efficiency ratings (up to 94% ErP)
- Instant hot water on demand with a combi boiler
- Smaller footprint and quieter operation

Improved Controls and Zoning
Control upgrades are often the most cost-effective way to reduce fuel bills and improve comfort:
- Programmable thermostats: set different temperatures for day and night
- Smart controls: remote app access, weather compensation and learning algorithms
- Zoning valves: separate upstairs and downstairs circuits to heat only occupied areas
Renewables and Heat Pumps
For environmentally minded homeowners in Alton, Liphook or Farnham, air source heat pumps can work well in well-insulated buildings. Hybrid systems pair a heat pump with a gas boiler for flexibility in very cold weather.
4. Maintaining Your Heating System
Even the best boilers and controls need regular attention. Annual maintenance helps prevent breakdowns and maintains efficiency:
- Annual boiler servicing by a Gas Safe engineer to check flue, pressure, safety devices and heat exchanger
- Powerflushing radiators and pipework to remove sludge and restore flow
- Installing magnetic filters to protect new boilers and extend system life
- Considering boiler cover for peace of mind and reduced repair costs
5. Practical Day-to-Day Tips
- Bleed radiators regularly: cold spots can indicate trapped air
- Fit thermostatic radiator valves (TRVs) to control temperatures in each room
- Use timers and thermostats to avoid heating an empty house
- Keep doors closed to retain heat in inhabited spaces
- Make the most of daylight: open curtains on sunny walls and close them at dusk
Frequently Asked Questions
How often should I service my boiler in a period property?
We recommend an annual service to keep your boiler running safely and efficiently. This also maintains warranty and coverage under most boiler cover plans.
Can I install insulation without affecting the look of my period home?
Yes. Internal wall insulation and secondary glazing can be designed to preserve original features. Always consult a heritage specialist where required.
Are heat pumps suitable for older houses?
Heat pumps work best in well-insulated properties. If you’ve upgraded loft, floor and wall insulation, an air source heat pump can significantly cut your carbon footprint.
