Hybrid Heat Pump – UVHHP

Unilux vertical stack hybrid heat pump units meet the requirements of UL 1995 / CSA 22.2 #236 – Issue 2011 Standard for safety heating and cooling equipment.

New construction hybrid heat pumps provide cost effective heating and cooling all year round without the need for changeovers. Hybrid heat pumps use a hot water coil to provide efficient in-suite heating. Cooling is supplied to the suite by a refrigerant compressor and DX coil. In both instances, air passes over a coil to be conditioned before being circulated to the suite.

Hybrid heat pumps are available in a variety of capacities and can be configured with many innovative options, including energy recovery ventilators with dynamic balancing. Each hybrid fan coil ships to the job site to specification and is manufactured with the highest-quality materials.

All heat pump units are performance and quality tested before leaving our facility.

20-gauge galvanized steel. Configured with front, back, left, right or top supply air openings. Cabinet is fully insulated with 1″ fiberglass insulation 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: Flame-spread rating no more than 25; Smoke-developed rating no more than 50.

Fan & Motor Assembly

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

Refrigeration Chassis

A completely removeable, floating design features an insulated compressor compartment with vibration isolation.

Hydronic Hot Water Coil Assembly

Coils corrugated aluminum fins mechanically bonded to ½” OD Copper tube. The number of rows and circuiting are selected to suit scheduled capacities. Coils are rated for a minimum working pressure of 450 psig.

Stainless Steel Drain Pan

The drain pan is one-piece stamped stainless steel pan designed to never leak. It’s positively sloped for drainage. The drain hose will form a running trap from the drain to condensate riser. The underside of the drain pan is insulated with ½-inch thick thermal and sound insulation.


Supply and return risers are type ‘L’ copper and condensate risers are type ‘DWV’. All have 75 mm (3”) deep expanded ends to facilitate field installation. Supply and return risers are insulated with 1” fiberglass insulation 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.

Ball Valves

Shut-off ball valves with garden hose thread connection.

Water Hoses

Used to connect chassis to supply and return water connections. Isolates compressor noise from the building’s pipe system.

Universe Thermostat

Digital, touchscreen thermostat is fully programmable with 4 programs per day, 3-speed fan control, temperature setting, time date and humidity level display. Wi-Fi connectivity is included for mobile and web application support, as well as Google Assistant and Amazon Alexa connectivity.


A 1-inch disposable filter is included with the return air grille.

Access Panel

20-gauge steel construction finished in a durable baked enamel powder coat. Includes integrated grille and a hinged door for easy filter exchange.

Grilles & Registers

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

Unit Tagging

Each unit is individually boxed and tagged with factory and customer-supplied information. Units can be tagged with specific room numbers, riser numbers and other unique requirements.

Optional Feature: Integrated energy recovery ventilator with dynamic balancing

Include an integrated energy recovery ventilator (ERV) with Unilux patented dynamic balancing in your heat pump. ERVs bring in fresh air and exhaust stale air and maximize energy savings. ERVs include anti-freeze technology and dynamic balancing to manage air pressure
