So that it’s pleasantly warm and pleasantly economical

Gas or heat pump? Solar or oil? That’s not a question of ideology anymore. Renewable and classical heating systems can be combined today. For example, condensing boilers achieve a maximum of energy efficiency by returning the exhaust heat back into the system.

Our certified energy consultants find the mix tailored to your demands and wishes, even as far as passive house technology. We’re even the right contact partner for block heat and power plants. Thanks to micro-technology, not only businesses but also homeowners can profit from electricity-heat coupling.

In addition, we’ve been thinking about water technology. Have you ever thought that half of your drinking water can be replaced by rain water? And don’t forget that we’re specialists for ventilation and air-conditioning technology. No small matter. Because a feel-good atmosphere begins with a healthful room climate.
