CARRY ON CARAVANNING WITH RINNAI HOT WATER INSTANT, CONTINUOUS, LIMITLESS AND SENSIBLY ECONOMIC FOR EVERY TYPE OF COMMERCIAL SITE Rinnai, the UK leader in hot water heating units and systems for all commercial and residential sites, has recently completed yet another installation at a caravan park and holiday multi-activity centre. Rinnai HDC 1500e external unit, fuelled by LPG, was installed at a site in rural Herefordshire as part of regular upgrades on the complex. The hot water was for a very specific function - the Disabled, Laundry and Dog Wash rooms providing, and it needed to supply more than 940lt/hr at times of high demand. The unit has a maximum output of 54kW and weighs just 31kG. Due to space and configuration constraints the Rinnai 1500e unit was selected and installed neatly on an external façade and accessorized with a pipe cover box to deter any vandalism and provide weather protection. As this is a pre-manufactured unit, no additional flue or ancillaries required, aside from standard pipe and electrical connections. The installation was easily completed in less than a single day. LPG is increasingly popular for caravan sites as it gives extra flexibility on fuel and very good cost savings for the owners and operators. LPG is one of the cleanest off grid energy sources and as such is the ideal fuel for water heating applications in rural areas that are off-grid. According to Chris Goggin, Rinnai’s Operations Director, Rinnai Infinity continuous flow water heaters combined with LPG gives end users, such as caravan site owners, for example, an unrivalled energy efficient and environmentally friendly solution. And our units are delivered to site LPG-enabled.” Rinnai, the UK’s leading manufacturer of the ErP A-rated Infinity range of continuous flow condensing gas-fired water heaters, supplies the best energy efficient range of low-NoX water heating units currently on the market. Advanced condensing heat exchangers combined with innovative down firing pre-mix burner technology ensures that every cubic metre of LPG is used to the maximum on HDC 1500e. One of the site concerns was Legionella proliferation, therefore a ‘SMART’ controls for the secondary return DHW systems in the form of an advanced temperature control system which allows for safe running of water at 42°C core temperature during the
