About Us


The history of SWELL SYSTEM goes back a long way, to 1970, when the first cast iron boiler under the GAS CEM brand was produced in our Sassuolo (MO) plant. Later, in addition to the production of boilers, our company began to deal with the marketing of the first solar thermal panels and heating stoves. In the 1980s, water treatment systems were added to our range of products.

At the end of the 1990s our company started to produce a small range of plastic accessories for underfloor heating. At the beginning of the 2000s there was another change in our production process: we started to produce radiant systems and created the brand SWELL SYSTEM.

Today we offer 28 systems for space heating and cooling. Our products are innovative, functional, energy-efficient and comply with all relevant standards. They provide uniform climate control in buildings and ensure maximum indoor comfort.


SWELL SYSTEM designs and manufactures radiant heating and cooling systems suitable for residential, commercial, industrial and public administration contexts. Our systems are designed to be fully integrated into the floor, wall or ceiling and to offer many advantages, from savings to energy efficiency.

In addition to radiant systems for room air conditioning, we produce radiant systems for air treatment and dehumidification. We also offer thermoregulation systems, integrated relaunch mixing systems and fan coil distribution systems.

Our work is based on constant research, which leads us to create unique, cutting-edge designs. The design phase is carried out carefully, taking into account all the latest technological advances in the sector. After the design we move on to the realisation of the systems, using the best materials and the most valid techniques and instruments. We then carry out testing and quality control to ensure safety and efficiency for both the installer and the end customer.

We manufacture radiant floor, wall and ceiling heating and cooling systems that comply with UNI EN 1264 and guarantee high standards of efficiency and functionality. Year after year we improve our products, offering our customers systems that are always up-to-date and optimised from a performance point of view.


SWELL SYSTEM values the environment in which we live. That is why our systems are designed to ensure optimum performance even at low temperatures and run on renewable energy. This allows us to contribute significantly to the reduction of greenhouse gas emissions. We produce sustainable radiant heating and cooling systems that guarantee an improvement in the energy efficiency of the building in which they are implemented of at least 32.5 %.

Our vision leads us to constantly invest our resources in research and development, with the aim of improving and innovating. We also invest in the training of all our collaborators, designers and installers. In this way we can look to the future with the certainty of continuing to offer cutting-edge, eco-friendly products and impeccable technical assistance.
