Fabulously efficient

Fabulously efficient, super effective boiler. Great value for money. Relatively easy to install - and any issues you might have they’ll get right back to you and resolve it within a day at most. Thanks so much.

Worst company ever took thousands of…

Worst company ever took thousands of dollars from us. Never delivered the units. Just a revolving voicemail. You can’t get in touch with anyone after they take your money. Buyer beware

We aren't the company that you experienced, as we never get pay in Dollar, and we always deliver and answer our customers.

SERVICE SECOND TO NO ONE.

SERVICE SECOND TO NO ONE.
This company has old school service and other companies should take a leaf out of Thermofans book of policies. I purchased a Thermofan TF1800 through one of their distributors and found it was faulty. I rang Thermogroup for advice and found them very helpful, they asked if I could try a few test first and unfortunately this did not resolve the issue. However they quickly responded with sending a replacement within 24 hours attached with a reply package to return the faulty heater. I highly recommend this company.

Great boiler

Great boiler. Compact, quiet, efficient, with adjustable power supply. Ideal for small flats. There is nothing like this on the UK market, according to my heating engineer with 20 years’ experience

Exceptional customer service, quality products

We ordered a central heating boiler from Thermogroup and received it very quickly. Everyone we dealt with was really helpful and kind, especially Cedric. While planning out the installation of our boiler we received loads of help with questions and advice.
Thoroughly recommend - very well priced, quality products and exceptional customer service!

Excellent choice

I just bought and installed this boiler which is being used for under floor heating, a water based system. Customer service is excellent, even before I bought it they explained everything how this works and what to expect. I have communicated with Mr Cedric and Mr Herman who both offered their help without complications and through the chat the phone and also through video calling. They are always ready. The boiler is very small compared to a CV Ketel, and very easy to operate, it makes a little bit of noise but if you get used to it, will not bother you anymore. The first time it took a few hours to warm the house but if you use it regularly then is not a problem at all. The house is warm and comfortable, I can not tell you anything about consumption yet, but I think will be worth it.
Thank you to all of you guys for the work and for the assistance.

Fantastic equipment, service and advice.

I cannot recommend Thermogroup enough. The advice and support has been excellent. The technical team listened carefully to our requirements and helped us specify the most suitable boiler. They also advised on installation and helped us find an excellent professional to do the work. Once ordered, the boiler and accessories arrived the next working day at no extra cost. The system is exactly as described, very robust yet simple to install and has now worked perfectly for over a year. We have a 9Kw boiler that runs 8 cast iron radiators easily. Very impressed.
