Ideal Heating Commercial has supplied four Evomax 2 100kW wall-mounted boilers operating in cascade on a standard height frame and header kit as the energy centre at Ash View Extra Care, providing heat to 50 POD HIUs with first fix kits and factory fitted hard wired Mbus heat meters.

Ash View Extra Care facility is a new development for Kirklees Council of 50 one and two bedroom flats located in Huddersfield.
Extra Care housing is a type of specialist housing designed to maintain the independence of older people who have care and/or support needs. The housing consists of self-contained flats with adapted design features, and care and onsite support services – including 24 hour access to emergency support if needed – to enable independent living.
Tried, tested and efficient heating
Evomax 2 is the UK’s number 1 selling wall hung commercial boiler, proven in thousands of applications across the UK. Highly efficient, it has up to 99.6% full load efficiency and up to 110% part load efficiency, can operate at up to 30° Δ T, and boasts a high turndown of 5:1. The four Evomax 2 boilers at Ash View Extra Care are running in cascade for an energy efficient solution as the cascade can turn down to accurately match any load from 400 - 20kW (20:1). This method also increases the proportion of time where the boilers are modulating at part load, instead of cycling on and off, to satisfy the changing demands of the network over a day.
The PODs installed in each of the self-contained flats at Ash View Extra Care are indirect i305 HIUs, meaning they contain two highly efficient stainless steel brazed plate heat exchangers to provide complete separation between the heat network for both heating and hot water. For users, the POD HIU is reassuring in its familiarity, looking just like a domestic combi boiler from the outside and with similar controls, but instead of burning gas it uses heat exchangers to transfer thermal energy from the distribution network. Its small footprint and compact overall envelope mean it can readily fit in a kitchen or airing cupboard or existing utility area.
As well as being energy efficient, a key benefit of employing a heat network at a facility such as Ash View Extra Care is safety as there are no flue routes or gas connections to accommodate within the premises.
Taking the first step into heat networks
Heat networks aren’t new – many apartment blocks were fitted with them in the 1970s – but only in recent years has the installation of them taken off thanks, in part, to the government setting a target to supply heat to 20% of homes through heat networks by 2050.
V&T (Plumbing & Heating Services) Ltd. were contracted to install the heating system at Ash View Extra Care. “Our past experience of working with Ideal boilers had an impact on selection, especially with the aftercare service provided” comments Tom Crawford, Design Engineer at V&T. “When we were looking at which HIUs / boilers to propose for the scheme, we looked at the commercial range offered by Ideal and decided to go with both the POD and Evomax 2 as they both met our criteria. It also made sense to stick with one manufacturer.”
Easy to install POD HIUs
POD HIUs have been specifically designed for hassle-free installation, with a first fix kit available which can be delivered and installed ahead of the POD unit so all services can be piped up, filled, flushed, and tested in advance. Tom has been pleased with the outcome: “The engineers also found installing the Evomax 2s, mounting frames and header arrangement easy; these were fitted in a matter of hours.”
V&T benefited from Ideal Heating Commercial’s free commissioning service on the Evomax 2. Using this service, there are not only time and cost savings to be had but commissioning carried out by an Ideal Heating engineer ensures that the boiler is operating correctly before it is put into service. Furthermore, when commissioned by Ideal Heating Commercial within three months of the installation date, a five-year warranty is automatically applied to the appliance at no extra cost.
