HEATING , VENTILATION & INSULATION
RINNAI AND H3 OFF-GRID
CREATING A HEALTHIER WAY OF LIVING
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 . 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 .
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 longterm 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 .
