Cotswold Heating Solutions

Take Back Control Of Your Heating

RadTherm® radiators are an innovative electric heating system that allows you to control the room temperatures individually. This maximises potential savings on your heating bills whilst not requiring any servicing. The convection feature of RadTherm® radiators ensures efficient heat distribution throughout the room, providing a comfortable and cosy environment.

Reduce Running Costs
  • Instant/rapid warm water
  • RadTherm® electric radiators typically use just 12–15 minutes of power per hour.
  • Mega heat distribution (x6 the surface area of other heaters).
  • Even heat coverage – no cold spots.
The Installation Process
Our team of expert electric central heating installers are all employed directly by us – no subcontractors, which means all are vetted, qualified and highly skilled/trained to install your electric heating system. Above all, they have great personalities!

They will work in a fast, yet methodical and thorough fashion to ensure a no-mess, no-fuss approach to installing your new heating system and/or hot water heating solution. Once installed it is time to commission your new heating/hot water system and our team will explain everything in detail to ensure you get the very best from your new investment.
Class-leading Warranties
Enjoy peace of mind with class-leading warranties:
  • 10-year warranty to heating element and storage core for all Sunamp heat batteries.
  • 10-year warranty on Tepeo Zero Emission Boilers.
  • 30-year manufacturer’s warranty on the RadTherm radiator body.
  • 5-year warranty on electrical components (double the industry standard).
