MHS achieves excellence

The latest specification MHS Ultramax R3600SB boilers have been installed at a major central London office development in high and low temperature circuits which meet the 260,000sq ft building’s heating and energy management system needs.
Constructed by Skanska, the ultra modern office development at One Kingdom Street is the latest addition to the Paddington Central scheme, a new mixed use area that has become established as one of London’s premier business, residential, healthcare and leisure destinations.
Five Ultramax R3600SB stainless steel premix gas fired condensing boilers, with a total output of nearly 4.5MW, have been installed at One Kingdom Street which has achieved outstanding green credentials with an Excellent BREEAM environmental rating.
The down-firing water cooled pre-mix burner arrangement of the boilers not only ensures maximum combustion efficiency; the NOx emissions of both the 3400 and  3600SB boiler series are Class five with the R3600SB models emitting just 11.5mg/kWh, easily exceeding the requirements for the best BREEAM NOx emission rating. 
Installation space saving has also been achieved in a bespoke prefabricated boiler room thanks to the small footprint of the boilers which combine low weight, compact dimensions and low emissions. Up to 1895kW is obtainable from a single unit. 
Three R3605 SB units have been installed to serve the building’s low water temperature circuit that includes air handling plant, main fan coil units and warm air heating for the floor space. Two smaller Ultramax R3600SB units serve a circuit operating at a flow temperature of 80°C serving hot water calorifiers and radiators.
Specifying consultant, Martin McLaughlin of Faber Maunsell said: “The low NOx emissions of Ultramax boilers were essential in achieving the building’s excellent BREEAM rating. Space saving efficiencies in the plant room were also achieved through the compact size of the units.”
