Product information

The powerful Heat pump Silent Mini with inverter technology guarantees efficient and quiet pool heating. With 4.000 W heating capacity, it ensures pleasant temperatures for pools with a maximum water capacity of 20.000 l. The app control (iOS or Android) enables convenient operation. The compact heat pump with the dimensions 52,50 x 37,50 x 45,50 cm (Ø 32/38 mm connections) is suitable for salt water and works in an environmentally friendly way with the refrigerant R290. With a low CO2 equivalent of 0,00075 t and extremely quiet operation (30 dB(A)), it offers optimum comfort.
Thanks to the energy-efficient inverter technology, the heat pump impresses with its low operating costs.  It is the perfect solution for any pool environment, easy to install and with 800 W maximum input power. Look forward to relaxing hours in the heated pool.

The piping or hose material is not included in the delivery.

FAQs from category Heat pumps:

The liquid in the pressure gauge is not water, but a stabilising liquid (similar to glycerine). This liquid causes the pointer to remain stationary even under strong vibrational loads (which occur with heat pumps).

This is condensation water that drips off automatically.

Use the 50 mm / 38 mm adapter supplied. You can attach a 38 mm swimming pool hose using hose clamps and Teflon tape.

All Steinbach air heat pumps are equipped with a titanium heat exchanger and can be used for salt water pools with a salt concentration of up to 0.5 %.

Yes, the air source heat pump is always integrated into the existing filter circuit after the filter system. Note that the filter pump has the required minimum water flow rate.

The most powerful heating is of no use if the following factors are not taken into account: Pools with a cover, e.g. solar cover, have a lower heat loss. Insulated pools have a much lower heat loss than pools without insulation. The filter runtime and thus the operating time of the additional heating must be taken into account. Wait 24 - 48 h until the set temperature is reached. The higher the temperature difference between the pool water and the outside temperature, the higher the energy loss. Take external influences into account. Heat loss can occur due to cold or strong wind. Minimise the flow rate of the heat pump within the minimum water flow rate of (depending on the heat pump model*) , so that the residence time in the heat pump is longer. *4 m³/h-6 m³/h = 049202, 6 m³/h-8 m³/h = 049207

The volume of the heat pumps depends on the type and output. You will find the technical data for each individual product. Heat pumps have become increasingly quieter in recent years and are currently between 30 and 40 dB(A). For example, 30dB(A) corresponds to the sound of your own breathing and 40dB(A) to a living room with closed soundproof windows.

EEb means that the water flow is insufficient. Raise the water flow using a bypass kit that regulates the heat pump.

EEc means that the ambient temperature is below 15°C. Wait until the ambient temperature increases. In the cold seasons autumn/winter, the heat pump must be dismantled.

The water that forms in the heat pump is called condensate. This is the moisture contained in the air that condenses when it comes into contact with certain cold components inside the heat pump. The more humid the outside air, the more condensate the heat pump produces (your unit may produce several litres of water per day). The water collects at the bottom of the heat pump and escapes through the drain provided.
