Ideal Commercial Evomax boilers get full marks at Adams’ Grammar School

Thirteen Evomax wall-hung condensing boilers from Ideal Commercial Boilers have been specified and installed to provide high-efficiency heating and hot water at Adams’ Grammar School, a selective state boarding school in Newport, Shropshire.

Established in 1656 and expanded over the years, Adams’ Grammar School now comprises a variety of buildings including a Georgian mansion and modern state-of-the-art science laboratories, all of which required a flexible, low-cost heating solution.

HMM Mechanical director Rob Mountford specified the very first Evomax at the school in August 2014 to replace an old, inefficient floor-standing boiler situated in the admin block plant room. The school was so impressed with the reliability, ease of use and quick installation of the Evomax – not to mention the subsequent reduction in running costs – that a programme was launched to replace all the school’s old boilers with Evomax models. To date, thirteen Evomax boilers have been installed in five plant rooms across the site.

“Because of the variety of ages, layouts and uses of the buildings at Adams’ Grammar School, the versatility of the Evomax has been extremely beneficial in meeting the different specifications. The basement plant room in the Library block, for instance, had limited accessibility, so the compact size of the Evomax was an essential factor to allow ease of transportation and fitting,” Mr Mountford said.

 “We are extremely confident specifying Evomax boilers as they are very easy to fit and wire up, plus we have never experienced a fault or a complaint from a customer. We are also using Ideal Commercial’s Evomax accessories for each installation, such as the insulated Frame & Header kit and the Common Flue Header, as they made the installation much easier and reduced fitting time by a good few days.”

The Evomax boilers are providing heating and/or hot water for five buildings including the admin block, the outdoor swimming pool, the brand new sixth-form building, the canteen and a Georgian mansion called Longford Hall that provides accommodation for 50 pupils. A further five plant rooms will be upgraded with Evomax boilers over the coming months to complete the school’s boiler replacement programme.

The most recent installation, which took place in the Longford Hall, required the boilers to run on LPG as connection to the mains gas was not an option because of the building’s more remote location. The hall’s previous boilers were antiquated oil-fired models situated in a basement plant room, so Mr Mountford’s team adapted an existing building on ground level to house the Evomax boilers.

This allowed the new boilers to be fully installed ready for the changeover, which minimised downtime to a single day so as not to affect comfort levels for the building’s inhabitants. The gas management system within each Evomax appliance is specially designed by Ideal Commercial Boilers so it can be modified for use with LP gas while ensuring the boiler offers the same advantages as those fuelled by mains gas, including compatibility with accessories like the Frame & Header kits and Ideal Commercial’s modulating sequencers.

The Evomax’s extremely high efficiency of up to 110% part load was an important factor for all buildings to minimise energy use – particularly for the outdoor swimming pool, where the boilers are running 24/7. Bearing in mind the previous boilers were inefficient, oil-fired appliances, the school is enjoying substantial fuel savings and environmental benefits as a result of this installation alone.

Site manager Graham Hook said: “We are extremely happy with the Evomax boilers. All appliances have been running without any issues at all and they are very easy to operate and program. We had a power cut at one stage and I was very pleased when the boilers automatically reignited the moment power was reinstated. We have noticed a significant reduction in running costs, and we are looking forward to calculating our total energy and cost savings after the final appliances are installed.”

Mr Hook is also keen to take advantage of the Evomax’s new five-year warranty: “We are now employing Ideal Commercial Boilers to commission all new boilers scheduled for installation, as this means that we can benefit from the five-year warranty offered on the range for even more peace of mind.”

Mr Mountford said: “The technical service provided by Ideal Commercial was excellent. They provided a one-day training course on the Evomax FOC, which was invaluable, and on the one occasion we had a query about the installation that couldn’t be solved over the phone, an Ideal Commercial engineer was on site straight away and the solution was quickly identified.”

Looking to the future, Mr Mountford said: “The next Evomax installation at Adams’ Grammar School looks set to be challenging, as the building in question dates back to 1928 and the boiler room is currently housing two huge cast iron boilers, buffer tanks and 2,500l of stored water. However, knowing that we’re installing the Evomax and that Ideal Commercial experts will be available if needed, I know the installation will be as straightforward as possible.”

With efficiencies of up to 110% part load and a wide output modulation of 5:1, Ideal Commercial Boilers’ Evomax range delivers impressive energy savings, exceeding the requirements outlined in the Energy-related Products Directive (ErPD). This market-leading performance combines with low NOx emissions of less than 40mg/kWh to offer a boiler solution that also qualifies for maximum BREEAM points. In addition, the high efficiency of the Evomax qualifies it for inclusion on the Government’s Energy Technology List, making the range eligible for the Enhanced Capital Allowance scheme.

Enhancing the efficiency of the Evomax range further is a comprehensive system of control options, which enable numerous operating parameters to be pre-set for both individual boiler and cascade installations. These include a modulating sequencer, room sensor, programmable room thermostat, outside sensor, tank sensor, safety interlock and pump kits. It is also easy to integrate each boiler with an existing BMS system via a 0-10V boiler control input.
