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 Liverpool 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 Liverpool's 7.5-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 Liverpool compares.
Liverpool's weather is shaped almost entirely by the Irish Sea - winters are mild relative to the rest of the North West (averaging close to 5°C through January) but persistently damp, with around 850mm of rain spread across roughly 200 wet days a year. That combination drives condensation on cold solid-brick walls, particularly in the Victorian terraces of Toxteth and Anfield, where infrared panels' surface-warming effect makes a measurable difference to indoor humidity.
The L-postcodes hold an unusually wide spread - Georgian merchant houses around Canning and Falkner Square, dense Victorian terraces in Toxteth and Wavertree, post-war high-rise stock in Everton, and the new-build apartments along the Pier Head and Baltic Triangle. Liverpool City Council's Healthy Homes programme has identified the Victorian solid-wall terraces as the highest-priority retrofits - most have no cavity to fill, so internal radiant heating is the practical route to EPC C.
Mains-gas coverage across Liverpool is very high, but the city has one of England's highest concentrations of fuel-poverty households - Public Health Liverpool flags it as a major preventable health driver. Replacing an expiring combi with a gas equivalent locks a household into another decade of volatile gas pricing; infrared panels paired with even a modest rooftop solar array meaningfully reduce winter import.
