Valves for a wide range of applications in the new foyer of Colston Hall in Bristol were supplied by Oventrop.

The new foyer of Bristol’s famous music venue, the Colston Hall, provides improved facilities. It incorporates a wide selection of Oventrop valves to control heating and provide hydronic balancing of the various heating and hot-water systems.

As well as general valves, Aquastrom T Plus multi-function valves are incorporated into the DHW system to prevent legionella risks. The Oventrop valves were specified by consulting engineers Arup and installed by MJN Colston of Bristol.

The new glass-fronted building has a spacious 5-storey atrium crossed at upper-floor levels by a series of bridges linking it with the existing main auditorium.

The heating system is based on two gas-fired condensing boilers with secondary circuits for DHW. Indirect calorifiers also receive heat from a solar heating system.

A constant-temperature circuit serves air-handling units, and a variable-temperature circuit is provided for the radiators.

A low-temperature variable circuit serves underfloor heating for the split-level atrium ground floor and two cafes.

Oventrop supplied isolation valves, commissioning sets, differential-pressure and double-regulating valves for hydronic balancing, check valves and strainers. The 60 radiators on the upper floors have presettable TRVs with Combi 4 lockshield valves. Aquastrom T Plus secondary-circulation regulation valves were used on DHW returns to simplify commissioning and the balancing of systems.
