Rinnai adds heat pumps to expanding H3 product list

New carbon calculation service allows customers to identify most effective heating system

Rinnai has expanded its range of low-carbon, hydrogen-compatible heating and hot water products to include heat pumps, as well as introducing a carbon calculation service that allows customers to identify the heating system that suits their needs. The Monobloc line of heat pumps is available in an assortment of variants ranging from 4 to 110kW.

Rinnai’s heat pumps are suitable for both domestic and large-scale commercial hot water applications. They use a cascaded system that enables multiple heat pumps to work in conjunction with  one another, which means greater operational performance for large applications. The HPI models omit minimum acoustics via an installed ultra-low sound capability, making them 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 refrigerants, 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 has an ERP rating of A +++ and can switch between settings of heating, hot water and cooling. 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.

Rinnai’s carbon calculation service considers design from a holistic perspective, taking into account capital expenditure, operational expenditure and carbon savings. The service will compare a customer’s current heating system to Rinnai’s product list of low-carbon, high-performance heating systems, allowing the customer to see the benefits for themselves. More information can be found on Rinnai’s website on the ‘Carbon Calculation service’ page.

Rinnai is an international manufacturer of hot-water heaters and heating systems that designs and produces more than two million units a year, with an established reputation for high performance, robust cost efficiency and extended product life cycles.
