Precision Engineering from Rinnai Japan: The World’s Biggest Provider of Natural Gas and LPG Water Heaters

The Rinnai range of instantaneous gas water heaters are distributed globally, and are all ISO 9001 and ISO 14001 certified. This ensures the hot water system from Rinnai has a global mark of quality and environmental best practice.

Rinnai instantaneous tankless water heaters, also known more commonly as multipoint water heaters, can be far more energy efficient than storage systems. In hot water production studies, the hot water production from a highly efficient LPG water heater or natural gas multipoint water heater have proven to reduce gas usage by up to 30% when compared to traditional storage tank water heaters.

Rinnai natural gas and LPG water heaters have had NOx emissions independently tested. The results demonstrate that the Rinnai range have some of the lowest NOx values available on the gas fired water heater market.

Rinnai Case Studies: Innovations in Safe and Efficient Water Heating Solutions

Find out more on how the Rinnai range of tankless water heaters have provided energy savings for both domestic and commercial buildings. Our case studies include on-grid natural gas water heater and off-grid LPG water heater success stories that prove time and again that Rinnai is a smart method of heating water for any application.

Typical Applications for Natural and LPG Water Heaters

Restaurants, leisure facilities including shower blocks, commercial kitchens, rugby clubs, caravan sites and industrial process are prime examples of hot water production ideally suited to Rinnai LPG water heaters or natural gas multipoint water heaters. As these applications require high volumes of water intermittently delivered at accurate hot water temperatures to ensure user comfort, safety or hot water heating system compliance.

Rinnai instantaneous water heaters have several in-built functions that make them the perfect choice for a wide array of hot water requirements. Firstly, Rinnai hot water heaters can supply high hot water flow rates of efficiently heated water on demand. The Rinnai commercial hot water appliances can supply over 1500 litres of water per minute of temperature accurate hot water ensuring that multiple hot water outlets can be serviced with energy efficient hot water production.

The Rinnai on demand water heaters can deliver temperature accurate hot water for the smart water heater process. This in-built innovative design feature uses microprocessors within every Rinnai natural gas water heater and LPG water heater to deliver accurate temperature control which is accurate to one degree of the hot water heaters set point.

This ensures that hot water production is compliant to water temperature guidelines like ACOP L8 for legionella prevention. This is a distinct advantage for hot water demands serviced by a Rinnai instantaneous gas water heater as hot water cylinders can struggle to maintain the hot water temperature.

The Rinnai range of tankless water heaters are available in both internal versions and external versions of hot water units, making them versatile and a simple solution for different building installation requirements.

The externally mounted instant water heaters are installed outside making them an ideal solution for limited space locations by freeing up internal plantroom space which is a major advantage when compared to hot water storage systems. The external version has frost protection built-in as standard.

The internal version of the N series gas fired continuous flow water heaters have advanced turbo-fan systems ensuring that the Rinnai range have market leading flue runs of over 45 metres. As a part of the design process, Rinnai can provide advice of common flue kits, from our extensive range of innovative solutions.

Rinnai continuous flow water heaters have a wide range of products ensuring that there will be a large or small capacity water heater for a wide range of building demand scenarios.

Rinnai multipoint gas water heaters are on-demand water heaters, therefore unlike hot water tanks as long as a cold water supply and gas supply are constant the Rinnai water heaters will deliver constant hot water 24/7.

Rinnai Over 100 Years of Natural Gas and LPG Water Heating Design

Rinnai have over one hundred years of manufacturing excellence, with a core competency in combustion system design. This competency enables Rinnai to implement energy efficiency at the core of our hot water solutions.

Rinnai instantaneous gas water heaters boast efficiencies in excess of 95% for both natural gas fired water heaters and LPG water heaters. The Rinnai range are also classed highly efficient water heaters under the ERP labelling scheme certifying Rinnai instantaneous gas water heaters as an energy saving solution.

Rinnai modern water heaters come with market leading warranties because of the precision engineering and robust materials used in our heat exchanger technologies. For more product specification details on our continuous flow gas water heaters, ask us a question today.

Renewable LPG Hot Water Heater Range and Hydrogen Ready Continuous Flow Gas Water Heaters

The wide range of Rinnai gas fired instant water heaters come pre-set as propane gas water heaters or natural gas warm water generators, making the selection of products simple. As standard, Rinnai gas fired continuous flow gas water heaters contain a conversion kit which is available to convert the natural gas water heater to an LPG instant water heater within several easy steps.

Rinnai continuous flow water heaters are also ready for alternative energy as our commercial and domestic water heaters are certified as I2HY20, meaning that they are ready for 20% hydrogen blending. This certification is a UK first for commercial instant water heaters ensuring reliable performance whatever the future energy mix.

Advanced R&D developments with the LPG water heater category means that Rinnai tankless propane water heaters are ready for alternative fuels such as Bio-LPG and renewable liquid fuels. This makes Rinnai modern water heaters an excellent option for cost-conscious off-grid projects.

Rinnai offer design support for a range of system configurations from hot water recirculation systems, high hot water volume systems, indoor water heater systems with cascade configurations, high hot water outlets based systems, mobile LPG propane gas water heater projects, and much more.
