Gas condensing boilers

Modern gas condensing technology utilises the additional heat energy contained in flue gases. Condensing boilers thereby achieve even higher efficiency with lower emissions compared to conventional heaters. Heating with condensing technology is ideally suited to space heating and for water heating.

Heat pumps

Advanced heat pump technology utilises the free warmth of nature in your surroundings, making you independent of fossil energy types as oil and gas. Find out how heat pumps work, what you should consider when installing one and how you can use a heat pump for cooling your home.
