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 Inverness 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 Inverness's 9-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 Inverness compares.
Inverness is one of the coldest urban areas in the UK - winter lows close to 0°C and a heating season that comfortably exceeds nine months. The Moray Firth keeps maxes a little above the Highland inland average, but ground frost is reliable from October through April.
The IV-postcodes cover an unusually wide geography - the Highland Council area is the largest local-authority area in the UK by land - and housing ranges from Victorian villas in Crown and Drummond, modern bungalows in Smithton and Culloden, riverside apartments and a large rural off-grid stock that depends on oil, LPG or electricity.
A meaningful share of Highland housing sits off the mains gas network and heats with oil, LPG or electric storage heaters. Swapping storage heaters for infrared panels cuts the cost of heating through a season that stretches past nine months, with no fuel deliveries to plan around.
