How to Heat Your Home for Less: Heat Pumps, Solar Panels & Underfloor Heating Explained
Energy bills have been a painful topic for UK homeowners. But the technology and government support to genuinely fix the problem has never been better. Heat pumps, solar panels, and underfloor heating — combined — give you the most efficient home heating setup available in the UK today.
Why most home heating systems are inefficient by design
Traditional gas boilers burn fuel to produce high-temperature water — typically 70°C — pumped around radiators. Every energy conversion loses heat you paid for. There is a better way.
What is a heat pump and how does it work?
A heat pump moves heat that already exists in outdoor air into your home — like a fridge in reverse. It produces three to four units of heat for every one unit of electricity consumed.
Key facts about heat pumps
- Work effectively down to -15°C outdoor temperature
- Run on electricity — can be powered by solar panels
- Produce heat at 35–45°C, perfectly matched to underfloor heating
- Qualify for the £7,500 Boiler Upgrade Scheme grant
- No gas supply needed — ideal for off-grid properties
Why underfloor heating and heat pumps are the perfect combination
Radiators need 70°C water. Heat pumps produce 35–45°C. That mismatch makes the pump work harder than it should. Underfloor heating runs at exactly the same temperature a heat pump produces naturally — covering the whole floor surface evenly.
Practical benefits of pairing UFH with a heat pump
- Heat pump runs at peak efficiency — lower bills, longer lifespan
- Rooms heat evenly from floor to ceiling
- No radiators on walls — more space, cleaner rooms
- Quieter operation, less maintenance than a boiler
- EPC ratings improve significantly
Where solar panels fit into the picture
Heat pumps run on electricity. Solar panels generate electricity. In spring, summer, and autumn a well-sized solar system can cover a meaningful portion of your heat pump’s running costs — effectively heating your home for free during those months.
What solar panels add to the system
- Reduce or eliminate the electricity cost of running your heat pump
- Generate power for lighting, appliances, EV charging
- Export excess energy back to the grid via the Smart Export Guarantee
- Payback periods of 7–10 years, system lifespan 25+ years
- Improve your property’s EPC rating
The £7,500 grant most homeowners don’t know about
The Boiler Upgrade Scheme pays £7,500 toward an air source heat pump installation. It applies to both new builds and existing properties including conversions, and is deducted from your quote upfront by your installer.
- Homeowners in England or Wales replacing an existing heating system
- Conversions and older homes qualify — not just new builds
- Valid EPC with no outstanding insulation recommendations required
- Grant claimed by your installer — deducted from your quote
- £7,500 per property, combinable with other energy measures
What makes Tritherm’s renewable energy offering different
Tritherm has partnered with the only UK company that manufactures, installs, and maintains its own heat pumps entirely in-house. No subcontractors. No third-party parts. One team, total accountability — from design through to aftercare.
Is this the right move for your home?
It makes strong sense if
- You are replacing an aging boiler and want to future-proof
- You are renovating and can install UFH at the same time
- You have no mains gas and rely on oil or LPG
- You want to improve your EPC rating
- You want to use the BUS grant before it closes
