I purchased a new static caravan in December 2006 which came with central heating - a Worcester 24i Junior RSF boiler. This model boiler was then discontinued in August 2007. The central heating in the caravan does not include a room thermostat and I would very much like to add a Mech RF Stat (a MT10RF as recommended by Worcester for this particular model). I do not know if it is because the boiler has been discontinued but I am having great difficulty in sourcing the MT10RF - surely it should not be difficult to source parts for a boiler that is only 12 months old? I have "googled" high and low without any success - the part number is 7-716-192-035. Any ideas?
