What is the Deye 8 kW monoblock heat pump used for?
The Deye 8 kW heat pump heats residential and commercial buildings through underfloor heating, radiators or fan coil units, cools in summer, and prepares domestic hot water for showers and baths.
- For heating, the water temperature can be set between 25 and 75 °C
- For cooling, between 5 and 25 °C
- For hot water, between 20 and 70 °C
How does a solar heat pump with AC and DC supply work?
The Deye 8 kW heat pump has a built-in Solar MPPT with 2 MPP trackers, each taking 2 strings of solar panels. When there is not enough solar energy, the unit switches to the AC grid and keeps running. It needs solar panels and a grid connection; compatibility with specific inverters, boilers or batteries is not stated in the manufacturer’s sources.
What heating output and COP does an 8 kW heat pump give?
At 7 °C outdoor air, the Deye 8 kW heat pump reaches 8.4 kW heating output at COP 5.0 with 35 °C flow temperature. At 45 °C water the output is 8.2 kW (COP 3.85), and at 55 °C it is 7.8 kW (COP 3.2). In cooling mode, at 35 °C outdoors and 18 °C water, the unit delivers 8.3 kW (EER 5.15), and at 7 °C water 7.5 kW (EER 3.45).
The power you need is chosen from the heat loss of the building, not from floor area. If one unit is not enough, several can be connected in parallel.
R290 heat pump installation and safety
This heat pump uses natural R290 refrigerant (propane, GWP 3). Because R290 is flammable, separate safety requirements apply to R290 units, so it is worth agreeing the installation location in advance, before you buy. The water connection is G1″ BSP, and the unit has a 0.3 MPa safety valve and a 5 L expansion vessel.
We handle it for you. We select the equipment for your site, deliver anywhere in Lithuania, install and connect it. The consultation before purchase is free.
What to know before buying a heat pump
- Energy efficiency: A+++ applies at 35 °C flow temperature; at 55 °C it is A++.
- Noise: the manufacturer states a sound power level of 59 dB for the monoblock.
- Outdoor air temperature: from −25 to 35 °C in heating mode, from −5 to 48 °C in cooling mode.
- Control: Smart-WiFi via smartphone.
