Key features

Purpose-built for buildings that can't run out.

Copeland / Panasonic scroll

Brand-name scroll compressors — one on 14–25 kW, two on 37–100 kW, four on 140–180 kW. Parts and service available across India.

Tube-in-shell condenser

Robust water-side heat exchange with a blue-finned evaporator coil and electronic expansion valve.

Built-in voltage protection

Standard across the Tempratech range — protection against the power fluctuations Indian sites actually see.

Hot & Cold, 8 °C to 60 °C

Heating and cooling from one system where the building needs both — chilled water and DHW off the same plant.

COP around 4.2

Roughly 350–450% operating efficiency against 95% for electric — the reason running cost falls so far.

Spec sheets for tenders

Installation

What the site needs to allow for.

Installation: Outdoor — terrace or ground level
Power supply: 380–415 V / 3-ph
Water temperature: 55 °C rated · 60 °C max
Unit weight: 140–1,300 kg by model
Service clearances: Per installation manual

Units need a level plinth able to carry the model weight, free air across the evaporator, and space to open the service panel. Pair with Glass Blu Magic storage so the unit runs in long, efficient cycles rather than short-cycling on every draw-off — our engineers size the tank with the unit at survey.

Running cost

A quarter of the cost of an electric system.

Because a heat pump moves heat instead of generating it, operating efficiency runs 350–450% against 95% for electric and about 90% for LPG or PNG.
