Rinnai H3 – Air Source Heat Pump Technology
The low-GWP heat pump array supplied by Rinnai ranges from 4kW to 110kW heating power. The wide range of air source heat pumps from Rinnai ensures that we can provide central heating and DHW solutions for commercial applications through to domestic projects such as underfloor heating. 
At Rinnai, we provide the complete solution including hybrid heating systems inclusive of R290 liquid refrigerant low-GWP air source heat pumps, hot water tanks, gas boilers and water heaters and electric heating solutions that support lowering the overall carbon footprint.
We are driving the narrative on SPF for air source heat pump projects. Highlighting wider system efficiencies and minimising carbon from the entire system. We do not just focus on COP (coefficient of performance) and SCOP, instead we consider the heat pump installation as a whole.
Rinnai Monobloc air source heat pump technology allows up to 7 units to be cascaded together, making the Rinnai heat pump range an ideal choice for any heating or hot water demand. The innovative ability of the system to switch between heating mode, hot water, and cooling mode ensures that the Rinnai range has flexibility and durability as standard.
The SL product category creates the ideal blend of efficiency and low sound levels ensuring compliance with the most stringent sound standards. The Rinnai range utilises low global warming potential refrigerants like R290 and R32. The range of low-carbon heating heat pumps has an ERP rating of A+++ making this range of heat pumps an environmentally sound choice for future refurbishment projects.
Low noise levels and consistent heating with R290 heat pump models
These models have the ultra-low sound capability making them suitable for areas with prohibitive sound legislation or low ambient noise requirements.

R290 heat pump technology for space heating and DHW
The R290 heat pump technology will satisfy the central heating and hot water demand of a wide range of applications from domestic to light commercial. The innovative ability of the R290 high-temperature heat pumps to supply hot water up to 75 degrees Celsius even in colder months with lower air temperatures ensures system and design flexibility.
These commercial air source heat pumps are highly energy efficient with a SCOP of A+++ due to the increased efficiency delivered with the use of R290 refrigerant.
The air source heat pumps use R290 natural refrigerant gas which has a GWP (global warming potential) of 3, making the Rinnai R290 high-temperature heat pump range a sustainable and future proof heating and DHW solution.
