Heating system equipment to suit your building and needs

The energy-efficiency of natural gas heating can be further improved by new condensing boiler technology. The improved efficiency is based on the recovery of flue gas heat and its utilisation as heating energy. The energy savings obtained can be more than 30% in comparison with traditional boilers. As well as being highly practical, Oertli condensing boilers offered by Gasum are superior in terms of their overall economic value.

A condensing boiler is able to utilise flue gas energy for heat production. The flue gas temperature is only around 5°C higher than the temperature of water returning to the boiler from the heat emitters. Therefore the system's energy efficiency is at its highest in low-temperature solutions. The use of a water boiler is recommended for household hot water production so that the boiler temperature in heating use can be kept as low as possible.

Household hot water can also be produced using a heat exchanger, which is when the boiler is set to operate at a higher temperature.

Oertli's latest heating technology combines natural gas and solar energy. Solar power is nature's most essential and purest energy. It is sustainable, always renewable and emission-free.
