“Adam the plumber and Shaun and Steve the electricians were very polite and good fun. They left the place like they hadn’t been in. The bungalow now has warmth when we want it, and my bills have also dropped.”

What we fit
Our electric heating solutions for Cornwall homes

Learn more about our electric radiators
Electric towel rails
Our towel rails keep bathrooms warm and towels dry, with no plumbing work needed. Slimline designs suit smaller bathrooms and cloakrooms.
Sunamp water heaters
Sunamp heat batteries give you hot water on demand from a unit far more compact than a traditional cylinder, freeing up cupboard space. There’s no annual service, and they work with solar panels.

Homes, holiday lets and everything in between
From cob and stone cottages on Dartmoor to holiday lets on both coasts, Devon’s homes ask a lot of their heating.
No mains gas
According to Cornwall Council (February 2025), around 35,000 Cornish homes aren’t connected to mains gas, and 14% of households rely on oil or LPG. Electric radiators need no boiler, flue or fuel tank, so you can heat your home room by room on the electricity you already have.
Granite and stone cottages
Thick granite, cob and stone walls are hard to run pipework through, and they hold on to damp and cold. Our radiators fit straight to the wall with no pipework, and we size each one room by room at the survey.
A damp, coastal climate
Each radiator runs to its own schedule, so slow-to-warm rooms can be held at a steady temperature and spare rooms heated only when you need them. A heat-retention core sealed against damp, and outdoor-grade powder coating, keep salt air out.
Holiday lets and second homes
Control every radiator from the app, wherever you are. Warm the house before guests arrive, and keep it frost-free between lets.

What Cornish customers say
A Cornish customer
“The way it’s transformed this house is amazing…”
Jenny swapped her night storage heaters for radTherm radiators in her home near Land’s End.
Jenny Wakelin Sennen, CornwallWe even heat a coastwatch station
We fitted the electric heating at the National Coastwatch weather station at Nare Point, on the Lizard: about as exposed to salt, wind and damp as a building in Cornwall gets.
Storage heater replacement
Night storage heater replacements in Cornwall
Night storage heaters are still common in Cornish homes, charging overnight and releasing heat through the day. They were a sensible choice when they were fitted, but they leave you with little control when the weather or your routine changes.
Electric radiators are the most common replacement: they heat a room when you want it, with each radiator controlled on its own.
Thinking of replacing your old night storage heaters? Here are some signs it might be time:
- Poor control: heat is released on a fixed schedule, whether you need it or not, and can’t easily be adjusted room by room.
- Rising running costs: your bills are climbing, and storage heaters give you little room to bring them down by heating only the rooms you use.
- Unreliable heat: most of the stored warmth is released early in the day, leaving rooms cold by evening, when you need it most.
