About CTC


With over 90 years of experience, we work consciously towards a sustainable and fossil-free society. All of our products are developed and manufactured in the Småland region of Sweden. We offer a wide assortment of products, such as ground source heat pumps, air-to-water heat pumps, pellet boilers, wood boilers and a whole lot more.

We trace our roots back to 1923, when we began to heat Swedish homes. We are best known for our green boilers, which have supplied heating to millions of households all over Europe. We were the first company to offer heating boilers with built-in hot water heating and we were the first to introduce air-to-water heat pumps. It is therefore no exaggeration to say that we have developed the industry.

CTC is one of Europe's leading manufacturers of heating products. We are located in Småland and we are – along with Bentone, Turboflame and Osby Parca – a part of Enertech AB, which sells products across the globe.

We stand for peace of mind, quality and sustainability!

We operate in many countries around the world
