Four Ideal Commercial Evomax 80kW wall hung condensing boilers, Frame & Header Kits and brand new Plume Kits have delivered time, space and cost savings for New Forest District Council after being installed at Marryat Court Older Persons Living Accommodation in New Milton, Hampshire. As well as delivering reliable, efficient heating and hot water to thirty-four individual flats, the council has estimated that this refurbishment project will save them up to 25% per year in fuel costs.
Marryat Court is one of New Forest District Council’s sixteen Older Persons Living Accommodation buildings. The plant room retrofit was arranged as the existing floor standing boilers had become very costly to run, operating at around 80% efficiency, and the council did not wish to risk the health or comfort of the residents should an emergency boiler retrofit project be required during the cold winter months.
The new Evomax boiler system was designed and installed by Rob Sowden, Commercial Gas Engineer for New Forest District Council. Rob worked with Ideal Commercial Boilers technical specialists at the design stage and throughout the project. He commented, “As usual the technical backup from Ideal Commercial was exceptional, especially with the specification of the new Plume Kits to ensure their termination over the first floor flat roof complied with the Clean Air Act.”
Ideal Commercial’s new Plume Kits are specially designed for use with Evomax boilers that need to be installed in awkward locations, as they allow the flue terminal to be easily relocated up to 10m from the boiler. Compatible with Evomax models up to 120kW, each kit includes a standard appliance connector, horizontal flue kit, special rain collar, external plume kit 1m and terminal.
Marryat Court’s previous plant room was situated below ground and consequently ground water had caused issues with corrosion over ten years. As a result, Rob decided to relocate the boiler house by making use of a room that had once been the warden’s office, now disused, and the adjacent bin store. The uninhabited office also had the advantage of housing the rising pipe work from the existing basement boiler room. As well as eradicating the risk of ground water issues, the creation of the new boiler room meant that 95% of the boilers, equipment, pipe work and controls could be installed without disruption to the existing heating and hot water, keeping downtime to a minimum and preventing discomfort to the residents.
Rob explained, “Due to the compact size and awkward layout of the new boiler room, a stainless steel flue system would have been expensive and difficult to install, as well as being visually unappealing. The flexibility of Ideal Commercial’s Plume Kits and their neat appearance, all at a vastly lower cost, provided the ideal solution. In terms of the boilers themselves, we have installed the Evomax, Frame and Header Kits and Low Loss Headers at many of our sites and have always found the ease of installation, high efficiency readings and the general appearance to be of a very high standard. Their compact size always makes for a more straightforward installation, too.”
Due to the Evomax’s installer-friendly features, Rob installed the majority of the boilers, headers, plate heat exchangers and pipework as a single-man project. He commissioned a Controls Engineer to install the new control panel and to relocate the Ideal Universal Controller, which had been installed a year previously. Once all the appliances were in place, the changeover from the old water heaters to the plate heat exchangers took less than one hour, preventing any inconvenience to residents.
Evomax is Ideal Commercial Boilers’ most efficient boiler to date with seasonal efficiencies of up to 97.2%, and Rob has calculated that the new system will deliver savings of approximately 25%, or the equivalent of £3,000 per year in running costs.
He explained, “If this project had gone out to contractors, a design consultant would have drawn up a tender document, the successful contractor would have put a percentage on the material trade cost and the hourly rate would have been higher. There would also have been disruption to the tenants because it would not have been cost-effective to work around the existing boilers and pipe work. As it was, we completed the project at around £30k less than the original estimate with no disruption to the heating or hot water systems.”
Ideal Commercial’s Evomax offers one of the widest output ranges of any commercial wall hung condensing boiler on the market, and now comes with a 5 year warranty (terms & conditions apply) as testament to its reliability. The new Plume Kit, as well as other accessories such as the Multiline Flue Cascade, build on the Evomax’s strong reputation for being easy to install by allowing even more siting options.
