I'd wasted a lot of time looking for my electric heating solution until I found Darby at Thermosphere. Not only was he very prompt in responding to my query but he also gave me good advice and put me in touch with an engineer who would be able to supply and fit an electric combi boiler and radiators. Excellent service.
We use Thermosphere smart heaters as standard in every garden room we build. Not only do the heater look fantastic with their glass front, but they perform perfectly. Our clients love the fact they can control the heating from their phone or Alexa device. Highly recommend Thermosphere heaters.
Have had one of their products for a few years and it has worked effortlessly. Recently contacted their customer services through an error on my part and wow, absolutely wonderful they really went above and beyond to help me out.
Our company has used Thermosphere for several years for the purchase of electric heating mats & thermostats.We always receive excellent customer service from their experienced telephone sales team backed up with an efficient next day delivery service .Highly recommend ..... a definite 5 stars !!!
We’ve had ThermoSphere underfloor heating and thermostats fitted for over a year. Top quality products with excellent service & support. Overall a great value package.

Without a doubt my choice in electric underfloor heating supplier. Great product which i use in as many of my tiling jobs as I can.
