About Thermaze
Welcome to Thermaze, where comfort begins beneath your feet. Located in London and the surrounding areas, we specialise in underfloor heating solutions that make your home or business warmer and more energy-efficient.
Our Story and Our Commitment to You
When Sergiu Grosu founded Thermaze in 2016, he had a clear vision: to provide homeowners in London, Essex, and Hertfordshire with underfloor heating solutions that truly work. He'd seen too many systems installed poorly, leaving homeowners frustrated and cold. Sergiu knew there had to be a better way.

Many of our team members have been with us for years. Why? Because they care about doing the job right. They take pride in knowing that at the end of each day, they've helped make someone's home a little bit warmer and a lot more comfortable.

Only after we've gathered all this information do we design your system. We use detailed heat loss calculations to ensure your system will provide the right amount of warmth for each room. And we consider practical factors too, like how to minimise disruption during installation.
