Rinnai’s Installer SHOW is packed with new products and services coupled with a welcoming site & stand – packed with refreshments, entertainment such as darts, golf putting and table football competitions.

The stand will also feature the H3 Rinnai heating & hot water system initiative that consists of:

  • H1– Natural Gas, Hydrogen and BioLPG-ready hot water heating units and systems & Boilers.
  • H2 – Hybrid systems featuring a mix of appliances and renewables such as solar.
  • H3 – heat pumps, instantaneous hot water heaters electrically powered and electric cylinders.

All technological options focus on creating decarbonization pathways that are technically, practically, and economically feasible and have been designed specifically to reduce carbon emissions and lower capital and operational expenditure. The H3 range is supported by in-house design support along with carbon, OPEX and CAPEX cost modelling.  

Rinnai’s H1/H2/H3 offers multiple avenues of cost reducing decarbonization across various energy vectors. To create a healthier way of living, Rinnai is expanding customer choices in hot water provision as well as heating domestic and commercial buildings through a wide range of renewable energy systems.

Rinnai’s solar thermal water heating systems are a market leading solution that saves up to 3.5x more carbon per m2 compared to conventional solar technology.

Once Rinnai’s solar technology is combined with the condensing hot water heater system, savings in carbon and cost can be made as the units will modulate from 58kW – 4.4kW dependent on the solar input. Therefore, gas will only be used to boost the temperature when needed. Rinnai’s solar hybrid technology harnesses renewable gains whilst maintaining robust and efficient operational performance.

Rinnai intelligent condensing continuous flow hot water heaters can save more than 30% in operational running costs when compared to gas fired storage systems, helping to reduce fuel costs and exposure to ever-increasing energy and climate change legislation.

All solar thermal products are precisely aligned with the hot water heating systems & units which are hydrogen blends-ready 20% and renewable liquid fuel (BioLPG and rDME) ready combustion technologies.

Rinnai’s H3 range of decarbonizing products includes commercial and domestic Low-GWP R290 heat pumps that contain a variety of features: the HPIH range of commercial heat pumps is suited towards schools, restaurants, and small retail outlets.

Rinnai’s HPIH Monobloc Air Source Heat Pumps – 21, 26, 28 & 32kW range can allow for up to seven units to be cascaded together or operate alone as one unit. Once joined together Rinnai’s HPIH Monobloc Air Source heat pump can serve increased demand for heating and hot water.

Rinnai’s HPHP series of LOW GWP heat pumps range from 48kW – 70kW. State-of-the-art technology added in the injection process outperforms gas compression technology and ensures that even with outside temperatures of –25 Celsius, heating, and hot water of up to 60+ Celsius can still be delivered.

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 the 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.

Rinnai is also showing the new and innovative KCM series of continuous flow water heaters into the UK market. The KCM series is designed to specifically increase customer savings in energy, capital, and carbon with the inclusion of internally refined technological advancements.

The KCM unit possesses micro-processors that ensures hot water is delivered at the exact pre-set temperature. The advanced micro-processors will measure incoming water temperatures and modulate gas input. This guarantees the system will only use the required amount of energy to increase water temperature whilst supplying limitless volumes of clean hot water.

The inclusion of micro-processors enables the customer to pre-set water temperature supporting the minimization of legionella and eliminating the risk of safety issues such as scalding.

The KCM series leads the UK market in gross energy savings and operational costs at 93% and are compact design reducing the requirement for installation wall and floor space (unit dimensions length 670x 470x 257). System set up, monitoring and error codes are all made easily available via inbuilt status monitors located at the front of the panel.

An all-electric ignition system has been added to ensure no energy wastage – as no additional energy is required to maintain unused water temperature. Hot water temperature is internally monitored, if any fluctuations that rise above 3 degrees of the maximum set temperature, operation of the system will immediately stop ensuring customer safety and low operational costs.

Rinnai’s H3 range is supported by free training courses, CPDs, FREE design services and extensive warranty options – simply visit for further details.

Rinnai’s staff will look forward to meeting you at the up-and-coming Installer event at the Birmingham NEC between the 25th-27th June where additional information on Rinnai’s low carbon product offering is freely available to anyone of interest.
