Comprehensive air-to-water cold climate heat pump solution

WPL A2W Climate Heat Pump can provide space heating, cooling, and DHW

The WPL 15 A2W Premium and WPL 25 A2W Premium cold climate air-source heat pumps use outdoor air to produce hot water for central heating, cooling and domestic hot water production. The compact monobloc design uses output-dependent control and efficient inverter technology, ideally matching heating and cooling output through the variable speed compressor. Improved room climate during summer is accomplished with active cooling using circuit reversal.

Flow temperatures of up to 149°F/65°C are achieved even at low outside air temperatures due to a combined enhanced vapor injection/enhanced saturated vapor injection that cools the scroll compressor. The high flow temperature makes the WPL capable of use in modernization projects that may need a high flow temperature, as well as in construction, new or old, designed for lower flow temperatures.

The waste heat from the inverter is used to raise the return temperature. In addition, demand-dependent defrosting by means of circuit reversal and the heating of the condensate pan by the refrigerant circuit increase the overall efficiency of the system. A hydrophilic coating on the fan nozzle prevents ice from forming, meaning that no electric defrost heating is required. High efficiency and low operating costs are realized all year round, thanks to optimally matched components.

The hermetically sealed refrigerant circuit uses R410A and is rigorously tested for leaks at the factory. The encapsulated refrigerant circuit and acoustically isolated compressor, plus modulating fans and wide gaps between the evaporator fins that reduce air resistance, make for extremely quiet operation. An emergency/auxiliary electric resistance heater is incorporated for efficient operation when necessary.

The integral anti-vibration mount enables the heat pump to be connected directly to the heating system, with a pivoting electrical connection panel for easier installation. The condensate pan is easily reached through a cleaning aperture on the back of the casing. The enamelled, corrosion-protected metal casing in alpine white is made from hot-dip galvanized, powder coated sheet steel. Fan grill, recessed grips and top cover are made from weatherproof, UV-resistant plastic in aluminum white.

HSBC 300 Integral

WPL pairs with HSBC Integral to create a complete system

The HSBC 300 Integral comprises a DHW tank plus buffer tank in a single appliance. Almost halving the space required for separate tanks side-by-side, this frees up valuable floor space. The connection between the WPL and the HSBC is hydraulic, not refrigerant. This comprehensive solution makes installation easy, affordable, and suitable for both new construction or existing system modernization.

The HSBC also houses the WPM heat manager controller for the system. The WPM is highly programmable but comes pre-programmed with factory-set default parameters for a quick initial start-up.
