How to Improve Heat Retention in Your Home

Keeping your home warm and energy-efficient during the colder months not only enhances comfort but also reduces energy bills and carbon footprints. Here’s a comprehensive guide to improving heat retention in your home.

1. Upgrade Your Insulation

Proper insulation is the foundation of heat retention. Focus on key areas:

- Loft Insulation: Warm air rises, so insulating your loft or attic is essential. Adding 270mm of insulation material like fibreglass or wool can make a big difference.

- Wall Insulation: Solid walls or cavity walls can lose significant heat. Installing cavity wall insulation or internal solid wall insulation can dramatically reduce this.

2. Seal Draughts

Cold air sneaking into your home undermines heating efforts. Seal gaps around:

- Doors and Windows: Use weatherstripping, draught excluders, or sealant.

- Floors and Skirting Boards: Fill gaps with flexible fillers or insulating tape.

- Chimneys: Install a chimney balloon or draught excluder to prevent cold air from entering.

3. Upgrade Windows and Doors

- Double or Triple Glazing: Modern glazing reduces heat loss and improves soundproofing.

- Thermal Curtains or Blinds: These add an extra layer of insulation. Keep them closed at night to retain heat.

4. Invest in Smart Heating

Smart thermostats and zoned heating systems optimise energy usage:

- Programmable Thermostats: Heat rooms only when needed.

- Zoned Heating: Focus heat on frequently used areas while keeping others at lower temperatures.

5. Improve Boiler Efficiency

An old or inefficient boiler could waste energy. Consider:

- Servicing: Annual servicing ensures your boiler runs efficiently.

- Upgrading: Replace outdated systems with a modern condensing boiler. For expert advice and installation, we can offer reliable solutions, including gas, oil, and LPG boiler installations.

6. Reflect Heat Back into the Room

- Radiator Reflectors: Place foil or specialised panels behind radiators to reflect heat into the room rather than letting it escape through walls.


---


7. Use Rugs on Hard Floors

Uninsulated floors can account for up to 10% of heat loss. Add thick rugs to prevent heat escaping through bare floors and to keep feet warm.


---


8. Ventilation Matters

Good ventilation prevents dampness without significant heat loss:

- Trickle Vents: Let air circulate without opening windows fully.

- Extractor Fans: Use in kitchens and bathrooms to avoid condensation without losing too much heat.


---


9. Harness the Sun

Maximise natural heat from the sun:

- Open curtains during the day on south-facing windows.

- Remove obstructions like trees or large bushes blocking sunlight (if feasible).


---


10. Install Renewable Energy Solutions

Long-term investments in renewable energy reduce costs and improve heat retention:

- Solar Panels: Use the sun’s energy for heating or electricity.

- Heat Pumps: Extract warmth from the air or ground, even in winter, to heat your home efficiently.

Final Thoughts

Improving heat retention is an investment in comfort and sustainability. Whether you’re insulating, upgrading your heating system, or simply sealing draughts, each step contributes to a warmer, more energy-efficient home.



Stay warm this winter while saving energy!
