Oventrop valves specified for replacement of church heating system
The replacement of the heating system in a church in Cockfosters, north London, includes the use of a range of Oventrop valves specified by Pasion Star, consulting engineers of Worthing. As well as the church area itself, heating is needed for a large hall, which has offices above, and other small halls. There is also a reception block with five bedrooms for retreat visitors and a Benedictine Centre for Spirituality.
The existing system in Christ the King Church had been in operation for many years and was a mix of cast-iron and steel replacement radiators. The condition was such that it could take 20 minutes to vent one of the steel radiators. Temperature control was not reliable, either.
The new system comprises gas-fired condensing heaters and modern controls. There are separate circuits for the ground floor and the first floor, each with their own mini plant room.
There are 60 radiators in all, with Oventrop AV6 TRVs and Combi 4 lockshield valves and 12 fan convectors.
These TRVs have a settable insert that permits the water flow rate to be adjusted to suit heat demand. Hydronic balance is provided by Hydrocontrol double-regulating and commissioning valves. Ball and butterfly isolation valves have also been installed.
The contract stipulated that M&E contractor Staward Engineering should stop work when a service was scheduled for that area or nearby; on some days there are several services.
