Air Source Heat Pump
GREENSEED® Pioneering Intelligent Water Heating Solutions Since 2012
The GreenSeed® DELTAlite is an air source heat pump water heater that extracts free heat from the surrounding air and moves it into your water. Properly installed, it delivers three to five times more heat energy than the electricity it consumes, which cuts running costs and CO₂ emissions compared with electric, gas, diesel or coal heating. DELTAlite comes in two sizes, 4–10 kW and 10–20 kW, with a COP of 4 to 4.5, water temperatures up to 70 °C, and an operating range of −7 to 43 °C. Built with a German-designed internal structure, a GMCC compressor and a digital colour touch screen, it runs ultra-quietly in homes and commercial buildings alike.
Why choose the GreenSeed® DELTAlite
- 3–5× more heat than the electricity it uses: heat is taken from the air, not generated
- High COP: 4 to 4.5 across the range, higher than first-class energy rating levels
- Low operating cost: far cheaper to run than conventional electric, gas, diesel or coal heating
- Ultra-quiet operation: an improved evaporator air-flow design keeps noise down in commercial buildings
- Wide application: works in ambient temperatures from −7 to 43 °C
- German design: a renewed, optimised internal structure
- Smart control: multi-function controller with a digital colour touch screen
Benefits of a heat pump
- Lower energy bills, especially when replacing conventional electric heating
- Lower running costs and CO₂ emissions
- No fuel deliveries needed
- Minimal maintenance required
- Helps achieve renewable energy targets
- Fully scalable: works on its own or with other systems
- Potential government incentives

FAQ
Frequently asked questions
DELTAlite is an air source heat pump water heater from GreenSeed®. It extracts heat from the surrounding air to heat water, with 4–20 kW hot water capacity, a COP of 4 to 4.5 and water temperatures up to 70 °C.
It uses a refrigerant cycle to absorb heat from the outdoor air and transfer it into your water. Because it moves heat instead of generating it, it delivers three to five times more heat energy than the electricity it uses.
COP (coefficient of performance) is the heat delivered divided by the electricity used. With a COP of 4 to 4.5, DELTAlite produces about 4 to 4.5 kW of heat for every 1 kW of electricity.
Because it delivers 3–5 times more heat per unit of electricity, a heat pump can cut water heating energy use substantially compared with a conventional electric heater. Actual savings depend on usage and site conditions.
Two: the AHP4–10 (4–10 kW, single fan, 220–240 V) and the AHP10–20 (10–20 kW, two fans, 380–415 V three-phase).
Up to 60 °C with R410A refrigerant, or 70 °C with R134A.
No. An improved evaporator air-flow design gives ultra-quiet operation, suitable for commercial buildings.
Yes. It has an IPX4 waterproof rating, an eco-friendly galvanized metal cabinet and an optional G Shield anti-rust coating, and it operates in ambient temperatures from −7 to 43 °C.
