RINNAI AND H3 OFF-GRID

Creating a healthier way of living with RINNAI

Rinnai’s innovative new product portfolio of H3 products – hydrogen biofuels, heat pump and hybrid technologies will deliver heating and hot water solutions for off-grid commercial and domestic properties. Operations Director Chris Goggin explains how the range is designed specifically to lower carbon, encourage greater cost efficiencies whilst producing enhanced product performance and system durability.

Personal preference of decarbonising commercial & home heating and hot water options will depend upon location and condition of domicile. It is likely that the proximity and densely packed urban populations will require clean gas dispersal, whereas rural locations not connected to the UK gas grid will necessitate a separate decarbonizing response. Heat pumps are the technically practical and economically feasible solution for home heating and hot water delivery to properties not connected to the UK grid.

Purchasing a heat pump is currently incentivized by the UK government which will provide a £5,000 grant through the national Boiler Upgrade Scheme. Heat pumps offer immediate decarbonisation and provide comfortable property heat as well as hot water. Heat pumps will become a vital part of UK carbon neutral domestic energy options in the near future.

Around 16% of UK properties are off grid and not connected to the national gas supply. Many of these properties are found in rural locations. Rural residences often retain large internal and external spaces that encourage effective heat pump installation.

A heat pump works by extracting heat from air outside and elevating its temperature using a compressor. Compressed heat is then dispersed indoors through radiators and underfloor heating. Residual heat is stored in a hot water cylinder used for showers and baths. Heat pumps ensure that all home heating will be carbon neutral.
Both the compressor and pump mechanism accept electricity. If installed correctly on to an appropriate property a heat pump will prove to be an energy efficient, effective tool of decarbonisation that delivers satisfying levels of comfort to the end-user.

Off-grid properties not connected to the main UK gas grid may also prefer alternative cylinder gasses. Renewable DME (rDME) is a molecule-based fuel that can be produced through a wide range of renewable feedstocks which allows for a quick and long-term sustainable production. rDME contains a similar chemical composition to both Butane and propane. rDME can be mixed with LPG in existing appliances for continuation in product operations.

rDME combusts cleanly and releases no “soot” emissions. Renewable Dimethyl Ether (rDME) has many fuel properties that make it easily used in sites and appliances using diesel as a fuel. It has a very high cetane number, which is a measure of the fuel’s ignitibility in compression ignition engines.

rDME reduces greenhouse gas emissions by up to 85%, better improving local air quality. NOx, SOx and PM readings are all heavily reduced through the implementation of rDME. Clean alternative fuels that can be sourced without problem, such as rDME, will be steadily introduced in the near future.

Future capacity of rDME is set to rise sharply: a demonstration plant is to be opened later this year, whist the first operational commercial site manufacturing rDME will be on-line during 2024 and located in Teesside.
Rinnai hot water heating units and systems which are off-grid can also be powered by BioLPG – a lower carbon intensive alternative source of fuel.

rDME and BioLPG will become increasingly accessible and easy to use making both fuels ideal for off-grid locations. Rinnai continuous flow water heaters are compatible with BioLPG and blended rDME so do not require adapting in order to access or accept either fuel source for off-grid energy demands making Rinnai continuous flow hot water units well suited to off-grid properties regarding high power outlet and designed hot water needs.

Europe and the wider world have entered a new age in terms of energy provision and security. Importation feasibility and morality have become serious issues: BioLPG and other fuels like rDME successfully navigate these ethical issues and deliver all suited power requirements for off-grid properties.

Biofuels such as rDME and BioLPG perform identically to commonly used carbon emitting fuels and end product produced by the UK gas transmission network. All off-grid carbon reducing energy demands can be met by Rinnai’s H3 range, BioLPG, rDME, heat pump, hybrid heat pump or solar power products.

 
Rinnai are also offering free CPD sessions on biofuels and hybrid solutions to all UK property owners.

RINNAI H3 PRODUCT ROADMAP TO LOWER CARBON

AND NET ZERO DE-CARBONISATION

Rinnai’s product and service offering is based on H3- Hydrogen, Heating and Heat Pumps – which allows any site in either residential or commercial sites to maximise the energy efficiency and performance in striving for NetZero and Decarbonisation. Additionally, Rinnai is developing and introducing electrical formats to all existing product ranges within the next few months. Rinnai’s new “H3” range of products includes a wide selection of commercial heat pumps as well as hydrogen blends-ready and hybrid hot water heating systems.

Rinnai is a world leading manufacturer of hot water heaters and produces over two million units a year. The company operates on each of the five continents and the brand has gained an established reputation for high performance, robust cost efficiency and extended working lives.

Rinnai’s commercial and domestic hot water products offer a limitless supply of instantaneous temperature controlled hot water and all units are designed to align with present and future energy sources and accept either natural gas or hydrogen gas blends. Rinnai units are also suited for off-grid customers who require LPG and BioLPG or rDME.

Rinnai units are UKCA certified, A-rated water efficiency, accessed through multiple fuel options and are available for purchase 24/7, 365 days a year. Any unit can be delivered to any UK site within 24 hours. System design services are available if needed and cost comparison services are accessible to all customers who require further cost detail.

Rinnai’s Innovation Manifesto clearly outlines the path to carbon neutrality and maintains a pledge to fully decarbonize company operations by 2050. Rinnai will further support the global clean energy transition by introducing a wide variety of domestic heating options across multiple energy vectors.

Rinnai is committed to decarbonisation. Rinnai’s water heating products are all hydrogen-blends ready NOW including the world’s first 100% hydrogen powered water heater. Rinnai products also accept BioLPG capable of delivering NetZero carbon emissions. Rinnai offer comprehensive training courses and technical support in all aspects of the water heating industry. More information can be found on Rinnai’s website and its “Help Me Choose” webpage.
