Reflections on 10 years in the commercial-boiler market — John Bailey.

10 years in wall-hung boilers

Boilers and the technology associated with them seem to change very slowly, and even quite an old boiler could, until quite recently, quite easily be replaced with like for like. One of the most significant changes has been the move towards wall-hung boilers and their use in cascade configurations, as highlighted by John Bailey, Vaillant’s sales director for commercial and renewable systems, reflecting on 10 years of Vaillant being involved with commercial systems in the UK.

space heating, Micronics, flowmeters

Micronics flowmeters help survey heating system at Heathrow

Micronic flowmeters have been used at Heathrow Airport’s Terminal 4 to survey energy usage in the heating system. The facilities staff at the terminal have a 5-year plan running to 2019, entitled Quinquennium 6, which includes the redesign of the medium-temperature hot-water system, which previously ran at 120°C. The requirement was to run the system at a lower temperature to be more cost effective, more environmentally friend and — crucially — safer.

Jaga, trench heating, space heating

Trench heating is an effective solution for cottage in Cheltenham

Trench heating has provided an effective alternative to radiators for heating a living room in Kenilworth Cottage in Cheltenham, owned by Richard Wheatley. He explains, ‘The room previously had a great big radiator on the back wall. It limited what we could do with the room. If we were to put a sofa in front of it, it would block the heat from circulating around the room and potentially damage the furniture over the course of time. The room also features large French windows.’
