Rinnai Goes Electric On Water Heating Products


Now available from Rinnai are electric additions to the comprehensive range of heating and hot water heating systems and units. UK energy strategists believe that clean and sustainable electrification is presently one of the best modes of reducing carbon emissions, maximising efficiencies and lowering end-user customer costs​​.

Rinnai has, therefore, adapted its extensive product range to include electric versions and to develop modern technologies in offering continuous flows of product innovation. More new launches are expected in the first part of this year.

Rinnai’s Infinit-E range is an optional three-phase all-electric water storage heater for commercial hot water applications. All electric storage water heaters are designed with flexibility in mind. All units are fitted with between one and six titanium elements. The KW rating within the Infinit-E range is scalable from 12kw to 72kw ensuring that our appliances are suitable for a wide variety of applications.

Each cylinder is manufactured with stainless steel adding durability and enabling extensive warranties. The use of stainless steel also makes the Infinit-E range lightweight and easily manoeuvrable when compared to glass-lined variants. The empty weight of the Infinit-E is 54kg maximum. All electrical elements can be fitted to a single-phase supply, should site limitations dictate. Each element within the appliance range has its own controllable thermostat with a temperature range of between 49 and 90 degrees Celsius. All elements are fuse protected and there is no need for expensive sacrificial anodes due to a tough stainless-steel build. 

All-electric systems can benefit from our modulating smart electric cylinder range - ensuring that the only direct electricity used is to fill the performance gap from the renewable heat source. Rinnai’s electrical hybrid solar heating and hot water systems deliver identical performance when compared to traditional options. 

Rinnai’s range of electric products include monobloc air source heat pumps that are available in an assortment of variants, from 4kW to 110kW. Rinnai’s heat pump technology ensures 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 commercial applications.

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 commercial heat pumps use LOW-GWP including R32 and R290, renowned for reducing electricity consumption by up to 10% and for holding a lower global warming potential (GWP). Rinnai’s HPI heat pump range is ratified with an ERP rating of A +++ and includes an operational ability to switch between settings of heating, hot water, and cooling. 

Rinnai’s HPI air source 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 by offering practical, affordable, and feasible solutions to all UK customers.

Rinnai is determined to offer UK customers assorted options of carbon reducing technology that ensures an improved healthy lifestyle. Rinnai is also keen on informing all UK customers in major changes and developments concerning the international energy market that may affect purchase or power options in the near and far future.
