STIEBEL ELTRON's air source heat pumps and ground source heat pumps provide energy-saving and environmentally friendly heat sources for central heating systems and are an ideal replacement for fossil and natural gas energy.

WPL 130 AC

Air source heat pump WPL AC series, split design, heating output power from 22kW to 65kW, suitable for central heating in the north, while providing cooling and domestic hot water functions. Among them, WPL 130 AC, single unit heating output up to 65.1kW (ambient temperature 2 ° C, water temperature 35 ° C conditions). Combined with a dedicated heat pump controller, the product can be cascaded into 8 modules with a module output power of 520 kW. The energy efficiency ratio (COP) of WPL 130 AC is 4.0 (ambient temperature 7 ° C, effluent temperature 35 ° C) and 3.6 (ambient temperature 2 ° C, effluent temperature 35 ° C)

WPF 66

Ground source heat pump WPF series, with heating output from 21.5kW to 67kW, is suitable for central heating in the north, while providing refrigeration and domestic hot water functions. Among them, WPF 66 has a heating output of up to 67kW (soil temperature 0°C, water temperature 35°C). In conjunction with a dedicated heat pump controller, the product can be cascaded into six modules with a module output power of 403 kW. The energy efficiency ratio (COP) of WPL 130 AC reaches 4.56 (soil temperature 0 ° C, outlet water temperature 35 ° C).
