SPRSUN heat pumps are manufactured from high-quality components with 25 years of experience. A durable and economical heating solution. The touch-screen control panel makes operation simple, and Wi‑Fi remote control is included so you can manage the unit remotely via a mobile app.

In the Monoblock series the refrigerant circuit is fully integrated into the outdoor unit. This solution ensures good thermal insulation, space savings and quiet operation. Its compact design also makes installation and maintenance easy. With a Monoblock unit you can also reduce installation costs, because factory‑performed refrigerant work is already completed: the installer only needs to make the water connections and required electrical work on site.

The air‑to‑water heat pump uses an inverter, which saves electricity compared with ON/OFF models. An inverter‑controlled air‑to‑water pump adjusts heating output according to demand. A common issue with ON/OFF pumps is short operating cycles in spring and autumn. Short cycles increase compressor starts; each start consumes considerable electricity and wears the compressor. Properly sized, an inverter allows continuous heating for most of the season without interruptions.

The new updated model has SG Ready functionality, allowing the pump’s consumption to be controlled according to wholesale electricity prices. Using SG Ready requires devices such as Shelly Pro 2 and Shelly Pro 3EM controllers to forward price data to the heat pump. A wiring diagram between the heat pump and Shelly Pro 2 is shown in the product images.

The update also includes an EVU function as standard. EVU enables solar panels to be integrated into the heat pump system. The heat pump increases heating power when solar electricity is available.

Installation summary
The unit is a Monoblock, so supply and return pipes are brought from the heat pump to an internal buffer tank. A separate indoor unit is not required. The manufacturer recommends a 60–100 litre buffer tank. A circulation pump and a dirt strainer must be installed on the pipe to the heat pump. The dirt strainer filters metal and plastic debris and other impurities from the heating system fluid to prevent blocking the heat exchanger. An expansion vessel must also be connected if the system does not already have one.

A touch‑screen display panel is supplied with the heat pump and is installed inside the living area. Cable length over 5 metres.

If you intend to heat domestic hot water with the heat pump, a separate DHW cylinder is required. For sizing the cylinder, use the guideline 50 l per person. The cylinder must have an internal coil. The return pipe from the heat pump is connected to a three‑way valve. The valve is controlled with three wires. The pump opens the valve to the DHW when the cylinder temperature falls below the set hysteresis. Pipes from the valve connect to both the buffer tank and the DHW cylinder. Returns from the DHW cylinder and buffer tank go freely back to the heat pump.
