Part of the Oilon and Lämpöässä ground source heat pump range, ESi is a flexible solution that has been awarded the best A+++ energy classification and the EHPA QL quality label. ESi heat pumps are typically used for heating in single-family homes, terraced houses, industrial locations, and farms. The heat pump’s ÄssäControl system even allows the system to utilize waste heat from different active cooling and refrigeration solutions used in agriculture and other fields. The heat pumps in the ESi range are especially suited for locations with limited installation space available or where an existing heating system will be used with the heat pump or as a backup system.
ESi heat pumps connect to an external storage tank. This makes them a good fit for locations with exceptionally heavy domestic hot water usage. If more capacity is required, you can connect several ESi heat pumps in parallel. An ESi heat pump works equally well in buildings with very low domestic hot water consumption as well as locations that already have a compatible, well-maintained single-section domestic hot water tank. ESi units can be connected to an ÄssäCooling system or to separate solar collectors.
Applications: buildings up to 500 m²
The ÄssäControl system used in ESi heat pumps has a clear touch screen with versatile function shortcuts, making it easy to control your heat pump. If required, you can even monitor and control your heat pump with a mobile device. Remote control for the geothermal heating system is provided as an option.

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.
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.
ESi can also be connected to your building’s system without the desuperheating circuit. This option is used when very little or no domestic hot water is used, or the building has an existing single-section storage tank that can be used with the heat pump. Even in this case, the heat pump will provide heating and produce domestic hot water with the same A+++ energy efficiency.
