Lämpöässä - Model T -Ground Source Heating System
Smaller T models are especially common in pieces of real estate suffering from severe lack of space or where the existing heating system is to remain as a parallel/back-up system to the ground source heat pump. The largest T models are well suitable for pieces of real estate characterised by large heated area and/or especially high hot domestic water consumption. You can get ground source heat for blocks of flats, terraced houses and detached houses with Lämpöässä T. Also industrial real estates, public buildings and farms are possible to heat with Lämpöässä T.
Ground source heat pump that can be connected in parallel
If the need for power increases, T models can be connected in parallel. If necessary, T series geothermal heat pumps can be dimensioned for part-power use. It is possible to connect cooling units and solar collectors to Lämpöässä T.
Technical description
We recommend to install the Lämpöässä geothermal heat pump to a warm space which has a floor drain. The space does not have to be fireproof. The geothermal heat pump has fittings on one of its sides and on top, which are good to take into account in the space where the pump is placed. It is good to leave an empty floor space of about 50 cm on the fittings’ side and about 40 cm of free space above the top of the pump unit. This should be taken into account when placing the unit in a low space, such as a basement. By leaving a sufficient space around the geothermal heat pump the installation is easier.
Control system
The ÄssäControl control system developed and manufactured by Lämpöässä is used in T 40-120 units by default. It allows controlling the operation of the entire geothermal energy system as concerns heating, hot domestic water production, and cooling alike. The control system collects history data and by analyzing this data it is possible to control the enitre system more efficiently and economically. Thanks to touch-screen and function shortcuts it is very easy to use ÄssäControl. There is also remote control available for ÄssäControl (WLAN, GPRS, fixed network) which enables remote monitoring of the system.
In Lämpöässä T10-31 -models a Lämpöässä 200 series controller is used as the control system.

Cooling applications and many other additional accessories available for E-model pumps. A few examples of accessoriesare:
Control system for multiple heating circuits
The standard package of a Lämpöässä geothermal heat pump includes a control system for one heating circuit. A control system for two or three heating circuits is also available, enabling different areas within the household to receive heating water of different temperatures. For instance, one temperature for floor heating and the other for a radiator network, or one temperature for the humid rooms and the other for the rest of the household.
Delivery package for two heating circuits includes in addition to standard delivery also pre-installed control system application, valve actuator, the actuator mounting kit, three-way valve, A-energy class heating circuit pump and flow sensor.
Remote access of ÄssäControl
The heat pump unit’s remote access allows the user to monitor and control the operation of the geothermal heat system via the Internet with e.g. a tablet or a smart phone. Remote access is possible in many different ways: via a wired cable web connection, via a WLAN modem or 3G. In addition, ÄssäControl is available with a remote alarm function in case of possible disturbances.
ÄssäControl DPV room sensor
The room temperature sensor measures the current room temperature, according to which it adjusts the temperature in the direction of the desired set temperature, keeping the room temperature nicely even.
The E -series heat pump units are used with separate water tanks. This makes it possible, if necessary, to place the pump even in small and confined spaces.
A wide range of different sizes of water tanks is available:
- 500 L
- 700 L
- 1000 L
- 1500 L
- 2000 L
- 2500 L
- 3000 L
- 4000 L
(Includes 6-10 kW electrical immersion and 2 x 45 L hot water coils.)
Accessories available for storage tanks:
Additional coil
The additional coil available for the superheaters allows the use of solar energy as a source of additional heat.
Change of coil from 45l-> 60l
Switching the coil to a larger size makes it possible to raise the temperature in the water tank.
Third hatch
Acid resistant coil
Coil made of acid resistant steel for pool water heating
Additional fee for detachable panels
Lowering the water tank
Additional electrical resistance
Complements the heating of hot water.
