Vertical Stack
Hybrid Heat Pumps

Model UVHP : Sizes 02-12 / 0.5 - 3.0 tons

Our Hybrid Vertical Stack Heat Pump combines the cooling power of a heat pump with the heating efficiency of a fan coil. Cooling is achieved through a refrigerant compressor and DX coil that distribute air throughout the suite with the help of a fan. Heating is provided by an efficient hot water coil connected to a building-wide hot water riser and boiler system. The air passes through the coil and is circulated throughout the suite by another fan. Compared to using a compressor, hydronic heating is much more energy-efficient and requires less mechanical maintenance, providing greater reliability.

Integrated ERV

Equipping your heat pump with our patented integrated Energy Recovery Ventilation (ERV) technology introduces fresh air into the suite while minimizing energy loss through an advanced heat transfer core. This not only enhances the efficiency of heating and cooling but also facilitates the transfer of moisture between the exhaust and fresh air, ensuring precise control over humidity levels for heightened resident comfort.

Standard Features

Cabinet

Manufactured with 20-gauge satin steel. Configured with front, back, left, right or top supply air openings. Cabinet is fully insulated with 1″ fibreglass with a thermosetting resin. It is coated on the air stream side with an acrylic facing without the use of flammable adhesives. Insulation inside the unit has a flame-spread rating no more than 25 and a smoke-developed rating no more than 50.

Drain Pan and Overflow Sensor

Stainless-steel drain pan with neoprene insulation. A flex hose connects the drain pan with the condensate riser to form P-trap and is easily accessible for cleaning. The pan includes an overflow sensor to detect rising water levels and turn off the unit to prevent flooding.

Risers

Supply and return risers are type ‘L’ copper and condensate risers are type ‘DWV’. All have 75mm (3″) deep expanded ends to facilitate field installation. Supply and return risers are insulated with 1″ fibreglass covered with a vapour barrier jacket, which complies with ASTM 84 for flame-spread and smoke-developed ratings. The insulation is continuous over the riser length within the height of the cabinet.

Supply Air Grilles & Registers

Double-deflection supply air grilles have adjustable vertical and horizontal louvers. They are constructed with light gauge, powder-coated metal.

Fan & Motor Assembly

A thermally-protected, multi-speed ECM motor is resiliently mounted to a centrifugal fan which has a galvanized steel forward-curved DWDI wheel in a galvanized housing.

Refrigeration Chassis

A completely removable, floating design chassis minimizes vibration and allows easy access for service. The chassis is complete with a rotary or scroll compressor enclosed in a sound dampening and isolated box, coax heat exchanger, TX valve, 4-way reversing valve, balancing valve, 2-way valve and motorized actuator, DX coil and R410a refrigerant piping.
