Wessex Modumax offers stacks of benefits at Teresa Gavin House
Hamworthy Heating has supplied an efficient and space-saving heating solution to Teresa Gavin House – the head office for construction and refurbishment contractor Mulalley & Co in Essex. The premises is home to over 400 professional, administrative and operative staff
The system upgrade
the floor area available, the new installation, which has reduced the area needed by nearly half, now means the best use of space has been achieved in the plant room. Available in 5 modules with outputs (@80/60°C) of
97, 116, 147, 196 and 254kW. Wessex Modumax can be specified as individual boiler modules or can be stacked two or three high in 15 combinations up to 762kW output. Featuring a compact and lightweight design, they offer simplified access when it comes to accessing rooftop, basement, or packaged plantrooms.
2 x Hamworthy Wessex ModuMax mk3 116/232 boilers T
o meet the heating needs of such a large and busy building, Teresa Gavin House needed an effective system to replace its seven existing
NGR floor-standing cast iron sectional Hamworthy boilers, which were coming to the end of their operational life, after over 30 years in service.
Solution
Keen to stick to a brand they could trust, Mullaley turned to Hamworthy, who proposed a system using two Wessex ModuMax mk3 floor standing, vertically stacked units, a new plate heat exchanger and a Chesil pressurisation unit. In line with updates to the building regulations Part L, it was also necessary to replace the existing boiler flue, as part of the new installation.
20 September 2024 As the main scope of the project was to reduce
space without compromising on power output, the chosen model consists of two Wessex ModuMax modules, stacked on top of each other, with a total out of 464kW. With the previous system using up most of
Modumax is a fully modulating boiler that offers the benefits of high turndown ratios and load matching for improved efficiencies. This means that the system delivers the right amount of heat at the right time, with little or no wastage. With efficiency and reliability at the heart of this project, ModuMax was the perfect choice for Teresa Gavin House. The stainless-steel aspect of the heat exchanger
was also a huge selling point for this project. Offering considerable resistance to corrosion which can help to maximise service life, Teresa Gavin House can now also expect to achieve valuable cost savings from reduced service and maintenance intervals. For further peace of mind, a 10-year stainless steel heat exchanger warranty offers added protection against any future issues.
Going forward The old system
Following a successful upgrade, Teresa Gavin House now benefits from improved efficiencies and increased space within its plant room, making it easier to access equipment. Completed in two months, building occupants are now benefitting from an efficient and reliable heating system.
