ThermoSphere Reviews 

I've always received excellent service from everyone at ThermoSphere. Friendly and professional. Their attention to detail is fantastic, and are always approachable. I would definitely recommend.

Excellent experience with Alaska at ThermoSphere. She talked me through the settings and was incredibly polite and helpful. Thank you so much Alaska. I highly recommend if you have any issues giving them a call.

We've had Thermosphere underfloor heating before and were very pleased with it, so when we moved house we decided to have the same system again. Last time we installed the whole system ourselves which was surprisingly easy, but we're not good with technology and needed help setting up the WiFi controllers. This time the system was installed for us but we had put off linking the thermostats to our WiFi. Today we remembered how helpful the Thermosphere technical people were last time and decided to tackle it. We spoke to the wonderfully patient Jodie who talked us through linking each of our thermostats. She gave us really clear instructions and, in spite of our incompetence, got us up and running on our phones so it's now super easy to control our heating wherever we are. We are more than pleased with Thermosphere and would definitely recommend it, and would particularly like to thank Jodie for her calm, friendly and knowledgeable help.

I am not young and could not fathom how to set my thermostats. I was talked through the whole process which took a lot of patience on their part. It was done with kindness and respect without being in the least bit patronising. Thank you Alaska

I had a good experience with Thermosphere. The boiler works well and was installed efficiently. The staff were friendly, professional, and took the time to explain everything clearly. Overall, I felt well looked after and would recommend their service.

well what can i say apart from absolutly amazing service from Rebecca Piggott.
I work on various luxury high end projects that require some tricky specs for underfloor heating.
I reached out to Rebecca to see what was needed and how i could create such a large room combining two seperate heating systems to work Separately within the bathroom and powder room.
I had no idea but after a couple of emails and working drawings submitted, Boom it was on my email within minutes.
Rebecca is brilliant and very knowledgeable with her products.
Rebecca is now my only point of contact for future projects and will only speak with her.
The project went ahead and we have a very happy client.
Thanks Rebecca ☺

I had a thermosphere boiler installed and had a few teething problems with knowing how to program it/efficiency. I contacted thermosphere and they promptly sent someone to look over the boiler to check installation and see if he could get it running as efficiently as possible. Darby took time to explain the system to me and gave me multiple tweaks to ensure the system ran as intended.

Brilliant Company- Big shout out Darby & Becky, always so helpful!

Fantastic, helpful and speedy response from Travis!

Travis Bell is brilliant , always quotes on time and achieves excellence in customer service.

Thermometer offer fantastic customer service with real people to support you. Not the usual barrier of chat bots, submit your problem on line etc.

Alaska returned my call quickly, very patiently went through every step to programe all 7 days with the same steps on my Touch Programmable Thermostat. Very clear, Alaska had a unit with her as she went through the process.
Brilliant service 👏 !

Really helpful and knowledgeable assistance. Problem identified so that we can go back to the installer.

I called and spoke to a helpful person who then transferred me to Travis in sales. He was knowledgeable and guided me in the right direction on my electric underfloor heating. He went the extra mile and referred me to my local stockist for a quote.

I recently had an issue with reconnecting my ThermoSphere system to the app and reached out for support. Alaska Bell got back to me straight away and was incredibly helpful throughout the entire process. Her communication was clear, professional, and genuinely friendly — she quickly understood the issue and guided me through getting everything sorted.

It’s rare to experience this level of efficiency and care in customer service these days, and I really appreciate the prompt attention and reassurance she provided. Everything is now working perfectly again!

Thank you, Alaska, for your swift and helpful response — outstanding service from ThermoSphere!

ThermoSphere make electric heating so easy.
Brilliant service, from technical info to buying to setting up the system.

A quick response to a technical query which was handled efficiently and in a most courteous manner by Travis.

If I could give zero stars I would. Thermosphere products were selected by my underfloor heating installer with no input from me. they are supposed to be Wifi controllable but in fact they can only be turned up and down via app remotely and they cannot be reprogrammed to a schedule. They come with an arbitrary default schedule which can supposedly be changed on the thermostat itself through a fiddly process but even that doesn't work. I am therefore unable to schedule to take advantage of lower cost electricity tariffs. Five 'smart' thermostats were bought and installed in 2021 but very quickly were left unsupported (thermostats and app) as the company released new products. The company say that I should buy new thermostats to replace them. It beggars belief that they think it acceptable to supply equipment with only short term support and no backwards compatibility in their new app. Surely, heating systems should offer decades of support, not 3 years. Do not buy from Thermosphere if you have long term expectations of a working product and support.

Had our thermosphere thermostat now for more than a year. First one installed broke after 6 months. Replaced quickly but new one just is hopeless as initiates a boiler turn on randomly in the middle if the night when the house is empty and without a timed turn on
Most of our gas use at present is due to erroneous firings initiated by the thermostat as above. Is anyone else having these issues? Have reset the device numerous times- which works for a few days then it’s back to random turns ons for our GCH
It’s costing us a fortune!
