Units Available
The GreenLine R290 300 is a powerful, high-efficiency monobloc air source heat pump engineered for larger UK homes, multi-dwelling properties and specialist applications. Using natural R290 refrigerant, it extracts renewable heat from the outside air and upgrades it to deliver reliable space heating and domestic hot water — even in the coldest British winters. With flow temperatures up to 75°C, it works with many existing radiator systems, so expensive upgrades are often unnecessary. Quiet, robust and future-ready, the 22 kW GreenLine 300 is the ideal choice for properties that demand higher capacity without compromising on efficiency, comfort or long-term reliability.

FAQs

Got questions?
We've got answers

What size Greenline do I need for my home?
The right size depends on your home's heat loss, which we calculate during the survey. As a rough guide: 6kW for well-insulated 1-2 bed homes, 9kW for 2-3 beds, 12kW for 3-4 beds, and 16kW for larger properties. We'll always size your system correctly to ensure optimal efficiency.
Can Greenline heat my hot water too?
Yes! The Greenline heat pump connects to a hot water cylinder to provide all your domestic hot water. We typically recommend a 200-300 litre cylinder depending on household size. For maximum efficiency, we can also pair it with our Ecocent dedicated hot water system.
How does Greenline perform in very cold weather?
Greenline continues to operate efficiently down to -20°C. At 0°C it still achieves a COP of 3.5+, meaning 350%+ efficiency. Even at -7°C (the UK's design temperature), it delivers 280% efficiency - still far better than any boiler.
Is the Greenline suitable for radiators or just underfloor heating?
Greenline works brilliantly with both! While underfloor heating is ideal due to lower flow temperatures, most existing radiator systems work well - especially if they were originally oversized (as most are). We assess your radiators during the survey and advise if any upgrades would benefit you.
