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 Glasgow 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 Glasgow'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 Glasgow compares.
Glasgow's west-of-Scotland climate is wet rather than cold - January averages sit around 2.5°C but rainfall is over 1,200mm a year across more than 200 wet days. That kind of persistent damp drives mould in the older tenement housing, and the cure is warming wall surfaces directly rather than just heating air, which is the mechanism radiant infrared uses.
The dominant Glasgow property type is the red-sandstone tenement - typically four storeys, eight flats, shared close. The West End, Govanhill, Dennistoun and Pollokshields hold the largest concentrations, and Glasgow City Council estimates close to a quarter of all city housing sits at EPC D or below. Many of these tenements are common-good or co-operative owned, which slows any retrofit involving shared building services.
Mains gas reaches the bulk of Glasgow housing, but the upper floors of older tenements often have no practical gas route and rely on storage heaters. The Scottish Government's Energy Efficient Scotland programme runs alongside ECO4 and is the main route to grant-funded retrofit; PoweRad installs sit within the relevant approved-installer frameworks.
