Heat pumps are now included in the H3 product list of solutions that further expand on Rinnai’s array of present and future low carbon products. Rinnai are also introducing a unique carbon calculation service which enables customers to identify a low carbon, high efficiency system suitable for their needs.

Rinnai’s carbon calculation service considers design from a holistic perspective of capital expenditure, operational expenditure, and carbon savings. Rinnai’s carbon calculation service will compare a customer’s current heating system to Rinnai’s product list of low carbon, high performance, heating systems that are all proven to reduce cost. This feature will enable customers to view proven benefits when investing in a Rinnai system.

Rinnai’s H3 line of products further build upon its high efficiency hydrogen blend ready and BioLPG ready molecule powered systems. Rinnai’s range of Monobloc air source heat pumps is available in an assortment of variants, from 4 to 110kW.

Rinnai’s heat pump technology means that up to and including seven units can be cascaded together. A cascaded system means that multiple heat pumps can work in conjunction allowing for a level of functioning synchronicity that produces greater operational performance for larger applications.

Designed to Satisfy Domestic Through to Large Commercial Hot Water and Heating Requirements

Rinnai’s heat pump range is designed to satisfy domestic through to large commercial hot water and heating requirements. Rinnai’s innovative heat pumps systems include an ability to switch between settings of heating, hot water and cooling.

The HPI models omit minimum acoustics via an installed ultra-low sound capability making Rinnai heat pumps suitable for any area with prohibitive sound legislation. Rinnai’s HPI range operates within compliance of all stringent sound standards ensuring low-sound functionality.

All Rinnai heat pumps use R32 refrigerant, renowned for reducing electricity consumption by up to 10% and for holding a lower global warming potential (GWP). R32 has a GWP one-third lower than other refrigerants. Rinnai’s HPI heat pump range is ratified with an ERP rating of A +++.

Rinnai’s HPI heat pumps, hybrid formations, electrical formats and hydrogen gas mix powered water heaters are part of the H3 range of products. All new models are designed to embolden decarbonisation, energy efficiency and reduce customer costs.
