Lämpöässä Esi, Emi, Eli

A ground source heat pump can extract geothermal heat from soil, water bodies or a bore hole. The Lämpöässä E-series heat pump units are used with separate water tanks which store the heat energy produced by the heat pump. In addition, it is possible to connect multiple water tanks in parallel. Esi models utilise Lämpöässä superheating technology that takes care of heating and final domestic hot water heating simultaneously. Due the technology, immersion heaters are not required upon normal use.

If the need for hot domestic water is low, Lämpöässä can be connected without the superheating feature with separate storage tank. In case the building includes previously installed water tank that is suitable for geothermal heating, it can be connected to Lämpöässä heat pump.

The ÄssäControl control system developed and manufactured by Lämpöässä is used in all E-series heat pump units by default. It allows controlling the operation of the entire geothermal energy system as concerns heating, hot domestic water production, and cooling alike. Thanks to touch screen and function shortcuts it is very easy to use ÄssäControl. The control system collects history data and analysis of this data allows more efficient and economical control over the entire system.

There is also optional remote control available for ÄssäControl (WLAN, 3G, fixed network), which enables remote monitoring of the system.

Cooling applications and many other additional accessories available for E-model pumps. A few examples of accessories are:

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.
