Nothing on the walls. Heat only the rooms you use. Slim white PowerBoard panels on the ceiling warm people and everything in the room directly, instead of heating the air first. Supplied and installed across the UK.
For a typical UK 3-bedroom home, PowerBoard infrared runs at £562–£1,263 per year (~£47–£105/mo) in real-world zoned use - only heating the rooms you're actually in, with panels cycling instead of running flat-out like a radiator. Pair it with solar PV + battery storage and that drops to £57–£758 per year (~£5–£63/mo). Gas runs £800-£1,400, oil £1,200-£2,000, LPG £1,500-£2,500. Costs vary based on insulation, panel sizing, and energy tariff.
Oil & LPG homeowners save most. Fuel costs 40-60% higher than gas means the running cost saving from switching is larger for rural properties.
Pair with solar PV + battery. Infrared panels respond instantly, so a solar PV + battery setup can cover most heating demand directly. Diverter-only setups can't power panels in the evening - battery storage does.
How these figures are calculated: All PowerBoard figures above come from the same formula used by the calculator below - UK 3-bedroom home at 27p/kWh. We keep this rate fixed, set just above Ofgem's price cap when we chose it (26.32p, October 2026). The "all rooms, full demand" line is a like-for-like worst case where every panel runs as if it were a radiator covering the whole property. "Typical zoned use" applies a 55% real-world utilisation factor to reflect how PowerBoard is actually used: only the rooms in active use are heated and panels cycle once at temperature. The "with solar" line assumes a 4kW solar PV system with battery storage. Run the calculator with your own home's details for a personalised figure.
Annual running cost estimates for typical Belfast properties, based on the comparison-table benchmarks above.
Gas / electric figures are UK 3-bed mid-points scaled by property size. PowerBoard figures come from the calculator's own formula: about 5 heating hours a day at 27p/kWh, with panels actually drawing power only ~38% of that time (thermostats cycle panels off once a room is at temperature, and only the rooms in active use are heated), scaled to Belfast's 8.5-month heating season. The "with solar" column also assumes a 4kW solar PV system with battery storage. Use the calculator above for a personalised figure.

Climate, housing stock and energy mix all shift the headline figure. Here's how Belfast compares.
Belfast's maritime position keeps winters mild - averages around 4.5°C in January - but rainfall is over 950mm annually and the persistent damp is the dominant heating-comfort issue. Spring frosts can reach into April in upper Antrim Road and the western suburbs, keeping the effective heating season at around eight months.
The BT-postcodes mix red-brick terraces in the Holylands and Lower Ormeau, post-war estates in Andersonstown and Ballymurphy, and the new-build apartments at Titanic Quarter and Cathedral Quarter. Around 14% of Northern Irish households still rely on home heating oil - the highest share in the UK - and Belfast follows that pattern, particularly in the suburbs and on the city's edges.
Mains gas reached most of the Belfast urban area only after the Phoenix Natural Gas rollout from 1996 onwards, and many neighbourhoods remain on oil. Electricity prices in Northern Ireland are set under the Single Electricity Market and have historically run higher than GB averages, so panel-by-panel control to avoid heating empty rooms has a faster payback here than in most of England.
