The most economical cooling solution

All Oilon and Lämpöässä ground source heat pumps can be equipped with ÄssäCooling units, allowing you to cool your home during the summer months at a lower cost than any other system.

Unique superheat technology

Fine-tuned over several decades, our superheat technology enables your heat pump to produce domestic hot water as a side product of heating, making your system exceptionally self-sufficient. Thanks to our advanced superheat technology, domestic hot water is heated up to the required level 100% with geothermal heat. Consequently, if you select the heat pump’s heating capacity based on the coldest winter day, the heat pump’s electric immersion heater will never be used in normal operation. Your heat pump will be able to provide space heating and produce domestic hot water at the same time, meaning that your home’s heating won’t be shut off even if you take a warm bath.
