Project: fitting our concealed heating system throughout the property in Wanstead


We love being able to perfectly match the needs of our customers with the 3thermo system. That was the case for the client in Wanstead, who found it ideal for the property he was refurbishing for several reasons. It’s been quite a big project, working across the entire property, and we’re just about to hand it over.

The talks of the Wanstead project started last year, working with a client who is refurbishing his property. He has a flat and he realized that our concealed wall heating system is not only cost-efficient, but it is also a perfect solution to save space in his property by putting the heating units directly inside the wall.

On top of these qualities, he found another big reason to choose our system. Since his property has a lot of exterior walls, a lot of them are susceptible to damp, and there is a high risk of damp and mould forming in the house. It’s not only a factor that would speed up deterioration of a recently renovated interior, but a serious health hazard. Fortunately, our heating system is designed in a way that reduces damp and mould in the property. Since it heats the walls, it actually prevents the condensation from occurring due to difference in temperature between the walls and the heated air inside, which is what happens with traditional systems. Therefore our system serves a double purpose – not only providing heat, but preventing damp and mould.


The Wanstead project involved almost 30 of our radiators placed throughout the property, with the exception of the bathrooms where the electric underfloor heating was installed. While underfloor heating companies are our main competitor on the heating market, the installation with 3thermo is a much easier and quicker process, which makes us a popular choice. Installation of underfloor heating can get expensive, and it takes a lot of time as well, since first you have for installation to dry, then you have to screed it… there’s many different processes involved which takes time. Our system, on the other hand, goes directly onto the wall, we then put the piping at the bottom, run the necessary tests and at this point our radiators are ready for you to put plaster over the top. The whole process takes no more than a few days, which makes it quick and easy compared to the competitors. And while our materials might be more expensive than those used in underfloor heating, the overall installation works out much cheaper.


At the time of writing, the works in Wanstead are still under way: the radiators have been put up, but the plaster hasn’t gone up yet. At this stage, the next step is running pressure and heat tests, which allow us to ensure that all radiators are heating up correctly after installation. If there are any manufacturer’s faults in any of the units, we are able to notice it immediately and have it replaced before the plaster goes up.

The tool that we use for our heat tests resembles a gun. First you need to run water through the system and let the radiators start working. Then we’ll come around and use the gun to check whether all radiators are heating up properly, reaching the temperature they’re expected to reach. We also check if they heat all the way to the top and that there isn’t a significant difference in temperature between top and bottom of the wall. Once we have run the test, we can either exchange any radiators that don’t meet the expected standard, or, if everything works well, we will give you green light to start plastering. The test itself doesn’t take much time: it’s normally a few hours, depending on size of the property, no longer than a day.

After we finish testing in Wanstead, our job there will be done, as our client is using his own builders team for plastering and finishing off the interior. We are excited to complete another project and hand over the system that perfectly meets the needs of our client. We know that he’s very happy with what our system can do – so much, in fact, that he is already planning to work with 3thermo on two further projects he’s taking on. We believe it’s the greatest recommendation when our customers want to continue our collaboration and we’re looking forward to the future projects!
