Rinnai Warms Up The Bonny Banks Of Holiday Lodges On Loch Lomond With Off-Grid LPG Continuous Flow Hot Water Heating Units


Rinnai 1600e continuous flow water heaters, powered by LPG, have been installed in accommodation units at an off-grid holiday park on the banks of Scotland’s Loch Lomond, the UK’s biggest body of freshwater at just over 36 kilometres long​.

The Loch Lomond & Trossachs area is also a highly popular National Park - 1,865 sq. km (720 sq. miles) - and has a boundary length of 350km (220miles). Just over 50% of Scotland’s population lives within an hour’s drive of this National Park

The site, towards the southern end of the loch, is popular all-year round, as it is just 40 minutes from Glasgow. The site has a selection of lodges and chalets, many with outdoor hot tubs, accommodating up to 10 people per each unit. There is a leisure centre, swimming pool, restaurants and cafes plus communal areas used for concerts, especially tribute acts.

The Rinnai LPG water heaters are powered by LPG but can work just as efficiently on BioLPG – a lower carbon intensive alternative source of fuel. LPG is one of the lowest carbon emitting sources of fuel for the 15% of UK businesses and domiciles that function off-grid. Bio-LPG could be one of the replacements for LPG in the future meaning that off-grid sites can “drop-in” lower carbon fuels of the future and Rinnai continuous flow water heaters will be ready, thus futureproofing their hot water heating provisions.

BioLPG consists of renewable materials derived from a diverse mix of sustainable biological feedstocks and processes. Supported through cleaner sourced chemical ingredients BioLPG provides huge benefits in carbon reductions and air quality, compared to traditional off-grid fuels such as heating oil.

Further alternative fuel sources such as renewable biofuel Dimethyl ether (DME) can also be employed by Rinnai continuous flow water heaters. Renewable DME is like LPG. It is a molecule-based fuel that can be produced through a wide range of renewable feedstocks which allows for quick and long-term sustainable production.

DME combusts cleanly and releases no “soot” emissions. Dimethyl ether has many fuel properties that make it easily used in sites and appliances using heating oil. It has a remarkably high cetane number, which is a measure of the fuel's ignitibility in compression ignition engines. The energy efficiency and power ratings of DME and heating oil engines are virtually the same. R DME is safe and reduces greenhouse gas emissions by up to 85% better improving local air quality.

Rinnai is pioneering product development to support the green fuels of the future so that LPG water heaters and boilers today are ready for a greener tomorrow. Find out more about renewable liquid fuels by joining our newsletter at
