Hamworthy replaces boilers in Langham Hotel
Replacement boilers for the Langham Hotel in London’s Regent Street were chosen for their ability to be broken down into modules and carried up stairs to the rooftop plantroom. Hamworthy Heating supplied 27 ModuMax modules, each rated at 250 kW, to replace two large shell-and-tube boilers.
The previous boilers were installed in the late 1980s and were considered unlikely to last for another heating season. The hotel needed a reliable product that could match the heat demand.
Steve Collins of Kontrax Management, who specified the boilers, explains, ‘The modular solution enables this, and using multiple boilers increases system security — a crucial factor for a hotel which can’t be without heating or hot water. With access difficult and space in the plantroom tight, the modular, vertically stacking design meant Wessex ModuMax boilers were best suited to this project.’
The new boilers were installed in stacks of three and can be turned down to less than 1%, compared to 50% for the previous boilers.
The new boilers provide heat for the 380-room hotel and are the heat source for calorifiers for DHW.
The new boilers were installed alongside the existing boiler for a smooth changeover with no loss of supply.
