Kermi Indoor Climate

Just feel good.

Creating the perfect indoor climate is what inspires us.

We have been providing warmth and fresh air at home and at work since 1960 – because we know how important warmth is for our health and well-being. With our heating products, heating systems, and ventilation systems, we are making a sustainable contribution towards creating a healthy environment and a comfortable indoor climate for all.

Kermi x-optimised

We want to maximise well-being and thermal comfort with our products and solutions. Room air temperature, surface temperatures, air velocity, and relative humidity of the room air are all factors that need to be considered in this process.

When these variables feel balanced in a room, that’s when we feel comfortable – even when there’s a storm outside, it’s snowing, or the sun is making the mercury rise. Our products allow us to create complete solutions with a direct impact on comfort. This gives people the best possible sense of well-being and maximum energy efficiency within their living spaces. Today, we supply the market with heat pumps, heat storage tanks, controls, radiators, panel heating/cooling systems, and controlled residential ventilation.

The individual components and the integrated systems are environmentally friendly, economical, and highly efficient, in both new builds and renovation projects. For Kermi, it is vital that our products make a sustainable contribution towards reducing carbon emissions from residential buildings.

Optimised for maximum energy efficiency and the very best indoor climate. Optimising all of our products and solutions is what we are passionate about doing every single day. Throughout this process, we never forget that creating a healthy indoor climate is what matters most.

The Kermi x-optimised message visibly gets to the heart of our passion and our promise. This label indicates exceptionally high performance and energy-efficient products in every category. The products can be combined in any way and are fundamentally designed to fit together in every case.

The more products you combine, the greater the benefits. This means significantly lower energy costs, lower carbon emissions plus greater thermal comfort and an optimised indoor climate.

With Kermi x-optimised, we make a binding promise through our system: to provide an integrated heating concept with intelligent solutions. From efficient heat generation to energy-conscious heat transfer and sustainable residential ventilation.

x-optimised products

At a glance

A Kermi x-optimised system is created if two or more products from our range marked with the Kermi x-optimised label are combined.

In this case, the components in the system are so precisely coordinated with each other that their optimised interface management results in verifiable potential for creating energy savings.

The bottom line is significantly lower energy costs, lower carbon emissions, and all this combined with greater thermal comfort and maximum cosiness.
