How it works
Not the storage heater you remember
If the last electric heating you used was a night storage heater, this will feel like a different technology entirely, because it is. radTherm radiators heat up in minutes rather than hours, hold their warmth in a patented heat-retention core, and let you set every room independently instead of heating the whole house on a fixed overnight tariff.
The real question
Is it actually cheaper than what you have now?
Here’s how radTherm electric radiators compare with the two things most South West homeowners are switching away from.
| Compared on | radTherm electric radiators | Old night storage heaters | Portable oil-filled or panel heaters |
|---|---|---|---|
| How it heats | Heats the room you’re in, when you need it | Charges overnight, releases heat all day whether you’re home or not | Heats a room while switched on; no scheduling |
| Running cost | You only pay for the heat you actually use | Typically higher: you pay for a full day’s heat on a fixed tariff, used or not | Cheap to buy, expensive to run for whole-home heating |
| Control | Room by room, from your phone or the radiator | Whole house, fixed schedule, hard to adjust | Single room, manual only |
| Heat-up time | Minutes | Hours, and can’t be sped up once the charge is used | Minutes, but the heat fades fast once switched off |
| Lifespan | 30-year manufacturer’s guarantee | Often 20+ years old already, with parts increasingly hard to find | 2–5 years; not built for whole-home daily use |
| Installation | Fitted in a day, no pipework or boiler | Already installed (that’s the problem) | Plug in, no fitting, but not a real whole-home solution |

Built for our climate
Engineered for salty, humid South West conditions
The South West has a unique climate. High humidity, salt air and frequent damp mean a cheap radiator bought elsewhere simply won’t last.
- A patented heat-retention core with the heating conductors sealed inside it
- Hard-wearing powder coating to resist salt air
- A 30-year manufacturer’s guarantee on the key components
Still on night storage heating?
This is the switch we make most often
If you’re heating your home on an old economy tariff and dreading every winter bill, you’re exactly who radTherm radiators were designed for. See how the running costs compare, how long the switch takes, and what to expect from survey to switch-on.

Common questions
Electric radiators: what people ask us
The questions we’re asked most often by people researching electric heating across the South West.
Are electric radiators expensive to run?
Not compared with what they usually replace. Because radTherm radiators heat individual rooms on demand rather than the whole house on a fixed schedule, most customers use less electricity overall than they did with night storage heaters. Electric heating’s reputation for being expensive comes from storage heaters, not from the technology itself.
How energy efficient are radTherm electric radiators?
Every unit of electricity a radTherm radiator uses becomes heat in the room: there’s no flue, no combustion loss and no heat wasted warming a room you’re not in. The patented heat-retention core keeps releasing warmth after the element switches off, so the radiator needs less power to hold your set temperature.
Are electric radiators cheaper to run than storage heaters?
In most cases, yes. Storage heaters charge overnight on a fixed tariff and release that heat over the following day whether you’re home or not, so you pay for heat you might not use. radTherm radiators only heat when you tell them to, room by room, which is why most customers switching from storage heaters see their usage drop.
Is electric heating cheaper than gas?
It depends on your current gas system’s age and efficiency, and on your electricity tariff. Where electric heating tends to win is the total cost of ownership: no boiler servicing, no gas safety checks, no boiler to replace every 10 to 15 years, and a 30-year guarantee on the radiator itself. Our free survey includes an honest comparison for your home.
What size electric radiator do I need for my room?
It depends on the room’s size, ceiling height, insulation and how exposed it is. That’s exactly what the free survey is for: Neil measures up and recommends the right size and output for each room, rather than guessing from a rule of thumb.
Do I need an electrician to fit an electric radiator?
No. Our engineers handle the whole installation, including any electrical work, so you don’t need to arrange anything separately. We don’t use subcontractors.
How long do radTherm radiators last?
Every radTherm radiator comes with a 30-year manufacturer’s guarantee, with 5 years on the electronic components. Properly fitted and used, they’re designed to be the last radiators you’ll need to buy.
Can I control radTherm radiators from my phone?
Yes. Every radiator can be set on its own digital thermostat, or from the app if you’d like to adjust rooms and schedules from your phone. Smart control and the app
What’s the difference between a radTherm radiator and a night storage heater?
A storage heater charges overnight on cheap-rate electricity and releases that heat slowly over the next day, and you can’t easily control when or how much comes out. A radTherm radiator heats on demand, room by room, whenever you switch it on. It’s a genuinely different technology, not a modern-looking version of the same thing.
