Am new to this so thank you all in advance for any advice.
Moved into house last year where central heating is zoned (water zone 1, downstairs zone 2, upstairs zone 3). All radiators worked last winter. This winter when turned heating on, bathroom radiator cold but all other 6 radiators hot. Never got round to fixing bathroom radiator because we use the en-suite! This week, turned off 2 bedroom radiators while had heating on a lot upstairs. When turned them back on, one of these is now stone cold. Pipes leading to and from it (and to and from bathroom radiator) are stone cold. All other 5 radiators nice and warm. Any ideas? It's an old style boiler with hot water tank.
