Four R3604 boilers have been installed at Watermark Place, a fourteen floor, 42,350m2 commercial office development. The building also creates one of the large public realms north of the Thames in the City of London. 

Construction of the landmark city building is still underway. When completed it is expected to notch up an ‘excellent’ BREEAM environmental rating aided by the latest environmentally and energy efficient MHS Ultramax R3600 series condensing boilers.

The energy efficient Ultramax boilers will serve the building’s main fan coil units, underfloor heating, radiators, perimeter heating and air handling units.

Specifier Mark Terndrup of Waterman Building Services commented:  “Their low NOx emissions were vital in the choice of R3604 units for Watermark Place. Low NOx emissions will be an important contributory factor in the building achieving an excellent BREEAM environmental rating.”

Mr Tendrup added: “We have a long standing relationship with ELCO (formerly MHS Boilers) based on the ability of their products to meet both the technical requirements and economic conditions specified in our high value contracts.”

R3600 SB appliances offer important space saving and low weight loading. With output to floor space of around 380kW/m² and power to weight nominally at 0.98kW/kg; compared with a similar output conventional shell and tube boiler which is more than twice the weight and approximately 14 kW lower output per square metre of footprint (not including the space needed for the burner).

Commenting on space saving achieved Gary Edgar, Projects Director N G Bailey said:  “The compact arrangement of the boilers was the best solution due to co-ordination restrictions within the basement boiler house.”
