Rinnai delivers hot water to award winning Lakeland Holiday Park refurb

Rinnai’s continuous flow gas fired water heating units have been installed at the award winning Hillcroft Park which is set in the beautiful Ullswater Valley and offers year-round holiday accommodation to suit every taste and pocket. Hillcroft Park sits at the head of Ullswater above the pretty lakeside village of Pooley Bridge and offers traditional camping, camping pods, luxury lodges and holiday homes.

Recently the site, owned operated by the Heath family, added a new visitor pavilion and shower block to add to the existing facilities. Five Rinnai 1200i continuous flow units were installed as a cascade design so that any peak demand can be easily met – the 1200i delivers up to 35 litres of useable hot water per minute. The whole system is powered by LPG. All Rinnai units used in sites which are ‘off grid’ of the mains gas supply are supplied to site LPG ready enabled.

The hot water delivery system at Hillcroft Park incorporates a secondary return utilising Rinnai pure controls and common flue headers on the units to streamline the flue configuration. The site is based on sustainability and energy savings so electronic sequencing is employed on the system. These smart sequencing controls will optimise system performance by only firing additional units when more outlets are opened meaning the site only uses energy when it is needed.

Hillcroft Park has won many awards – notably the David Bellamy Conservation Award – several years running. This honour is awarded to those sites which met and exceed a variety of criteria – Managing their land as a haven for wildlife; Reduce their use of energy, water and other resources; Reduce, reuse and recycle the waste they produce and support their local communities.

The site is also no strange to celebrities – earlier this year the much-loved comedian, Johnny Vegas returned to Hillcroft Park to open the impressive, new facilities block.   Hillcroft Park became Johnny’s Lakeland ‘Home from Home’ for six weeks in 2017 during filming for the BBC series ‘Home from Home’ which appeared on BBC1.

Johnny opened the brand-new facilities building including a shower block that must be one of the most impressive in the UK when it comes to camping bathing facilities. Many of the fixtures and fittings would not be amiss in a luxury bathroom. Not content with high quality showers, basins, taps and tiles – campers also enjoy panoramic Lakeland scenes thoughtfully installed within the facilities themselves as well as a custom-made Lakeland soundscape of dawn chorus, sheep and, of course, water.

At Hillcroft Park, life takes on a slower pace – a throwback to those carefree, childhood holidays. While you can connect to the world wide web while you’re with us, we’d encourage you to ditch the digital, disconnect and discover simpler pleasures like a walk up the fell, a dip in the lake followed by a family feast or a quiet pint and a breath-taking sunset to the sound of birdsong.

The Rinnai HDC 1200i water heater unit uses heat exchanger technology to allow high capacity from mains pressure, thereby guaranteeing all the hot water needed, when it is needed on demand. As well as high capacities, the Rinnai unit has lower greenhouse emissions because of the new reduced NOx burner technology.

Available in both internal and external versions, HDC1200i gives end users 7% net efficiency* because the condensing process delivers up to 97% thermal efficiency, translating to significant energy savings when compared to standard tankless water heaters.

All of which makes the HDC1200i continuous flow hot water system by far the best option for all types of sites.

“The only time you are using energy is when there is a demand, in other words it is only burning gas when a tap or shower is being run and, design improvements by Rinnai have increased heat efficiency of its hot-water appliances from 80% to 95%, while decreasing gas consumption by around 14%,” says Gerard Gulliver for Rinnai.

The HDC1200i is also renewables-ready (suitable for use as a temperature booster for solar thermal and heat-pump) and can be easily configured in a manifold arrangement, ensuring they will never run out of hot water whatever the demand. As long as electricity, water, and gas supplies are connected, hot water is available when the hot water taps are open.

A DIP switch enables pin-point temperature setting and for safety, the over-temperature protection will switch off the heater should the water temperature exceed by 3°C above its set-point.

In real terms, swapping from a hot water storage system to a continuous flow hot water system can save a site several kW a day which equates to a lot of money a year at current prices.

Rinnai hot water flows with freedom at Maidstone fitness centre

Rinnai gas fired continuous flow hot water and heating systems have been specified for use at a leading fitness centre in Maidstone, Kent, replacing an old thermal store configuration. The site houses gyms, class studios, swimming pool, bar and café plus changing and showering facilities.

The site, one of the busiest gym and sports complex in the South East, had been served by an old stored hot water heating system housed in a plant room accessible only via a gantry.

Rinnai proposed 3 x 1500e continuous flow hot water heating units cascaded to cope with the high demands. But the most important point for the site was that the Rinnai units could be installed externally to the space starved plant room, resulting in a freeing up of space and heavily reducing additional expenditure for the additional remedial works that would have been required if the site chose to replace ‘like for like’. This would have required the hiring of cranes and demolition work.

The installation was characterised as being ‘straightforward’ and in a matter of days fully operational. The three Rinnai 1500e units deliver almost 3,000 litres of hot water per hour – that is about 40% more than the previous system and, uses around 42% less fuel – mains gas in this case. Because the Rinnai configuration modulates to demand, the site needed about 2,700 litres per hour at the three peak times during the working day – which it did with room to spare.

The Rinnai offering to the site included a proven electrolytic limescale inhibitor – this maximises system efficiency in hard water areas. Limescale is said to decrease the efficiency of a hot water heating system over a very short period if left untreated. *

Rinnai offers a uniquely-powered electrolytic scale inhibitor kit for commercial hot water systems. This is independently tested, and it is a low-maintenance way of protecting a property against the damaging and expensive impact of limescale.

It gives long lasting protection against the formation of hard limescale and ensures that bacteria have fewer places to hide because of cleaner surfaces. This means that there is protection to the capital investment. It is WRAS Approved and used and specified in all market sectors such as manufacturing, hotels, retail and supermarkets, healthcare and education as well as public authorities.

Contractors to the site Scott Combustion chose the Rinnai 1500e units for a whole variety of reasons – reliable & continuous flow of useable hot water, safe temperature water distribution at all tap and shower points, overall energy efficiency and ease of installation plus minimal ongoing maintenance costs. Hot water is vital to the wellbeing of all gym customers.

Scott Combustion is a premium commercial and industrial building services maintenance and installation company. Operating throughout the world, it is equipped with specialist divisions for gas and oil boiler servicing, general gas works, air conditioning/refrigeration and electrical installation and testing

Since its establishment in 1980, Scott Combustion has been providing expert services and has expanded to operate all over the world, having completed contracts in China, Nigeria, Georgia, Armenia, Japan, Latvia, Sierra Leone, Cameroon, Senegal, Azerbaijan, Venezuela and many other countries.

Says Darren Morse for the company, “We aims to alleviate the stresses and strains generated by building service concerns and to ensure our clients can operate their companies or organisations without additional complication.

“We offer a full range of building services – from the servicing of a gas/oil boiler, the chlorination of a water system to air conditioning and refrigeration services. We provide our clients with an exclusive service to manage every potential issue in the building operations sphere.”

On this and all sites Rinnai 1500e units have the water temperature pre-set through easy-to-use, built in digital controls, eliminating the risk of scalding and potentially eradicating the need for thermostatic mixing valves. Water can be used simultaneously at several points of delivery with no loss of heat.

The Rinnai units are designed for use directly off the mains, with no need for large, ungainly and energy inefficient storage vessels – and they deliver up to 37 litres per minute on demand.

An important feature that demonstrates efficiencies is the fact that Rinnai, manufacturer of the industry’s widest range of continuous flow gas fired water heaters, has ‘A’ rated Eco-labels on all of its units.

Eco-labelling of products offers transparency to specifiers and end users in a clear and simple guide when sourcing the most energy efficient hot water heating units. Rinnai products also meet and exceed the requirements of the Building Regulations Part L (fuel and power) and with these bespoke system arrangements they can offer G3 and ACOP L8 best practice. The possibility of Legionella breeding is minimised as Rinnai units have no storage and therefore limit the environment for bacteria production.

Energy is only used on a Rinnai unit when there is demand – simple as that. There is a big potential of annualised fuel saving costs with a HDC1500ei low NoX unit – these costs can be minimised next to any comparable type of storage water heater, such as gas direct fired storage water heater or indirect cylinder system connected to the heating boiler.

Rinnai Infinity HDC1500i Low NOx can boast the modulation 14:1, 56.6kW to 4.0kW, on both Natural gas and LPG gas and operate at a flow rate of as low as 1.5l/min. Thanks to this high modulation range, the Rinnai units ensure that the optimum amount of energy is used to heat the water, minimising waste and maximising system efficiencies.

The HDC1500e low NoX is extremely lightweight and easy to handle at just 31 kg.

By developing this holistic condensing technology initiative, Rinnai offers a simple, viable, cost effective, and energy efficient solution to consumer on-demand needs for hot water.

*The UK Carbon Trust considers that for each 1mm of limescale on the heat transfer surface there will be a 7% increase in energy input to the boiler to meet the same heat demand. (Low temperature hot water boilers – CTV051, Carbon Trust 2012).

Rinnai welcomes advent of ‘transparent’ energy labelling directive

Rinnai, designer and manufacturer of the Infinity range of continuous flow gas fired water heaters, welcomes the implementation of the Energy Labelling Directive on 26 September as it scores ‘A’ ratings on all its water heaters.

“Energy labelling of product offers transparency to specifiers and end users who will now have a clear guide for choosing the most efficient units available,” said Chris Goggin, Associate Director of Rinnai UK.

“Rinnai brings to market the most extensive range of ‘A’ rated appliances with load profiles ranging from small domestic models to XXL sized industrial units,” said Goggin.

“The ‘A’ rating applies to when a unit is in use – i.e. when fuel is being used, and as an ‘A’ rated Rinnai unit only uses fuel when water is being drawn the energy label crystallises our reputation for efficiency, as continuous flow water heaters suffer no standing losses with storage counterparts”.

When Rinnai water heaters are paired with solar thermal and the latest intelligent controls are used for ultimate heat recovery, even higher efficiencies can be achieved, he added.

Rinnai is also set up to offer installers expert help with system labelling. Installers will be responsible for creating the labels for those installations that combine a water heater with renewables, for example.

On 26 September 2015 The Energy Related Products (ERP) Directive, incorporating Ecodesign and Energy Labelling Directives for water heaters (Lot 2) come into force, meaning that water-heating products sold in the UK will need to meet minimum energy performance criteria in order to be legally placed on the market, and will require an energy label.
