We have just moved to new house which has two Vaillant boilers (no indication as to model nos, no instruction manuals, no help from previous owner). One works most of the radiators in the house and is fine, the other works the hot water (no problem there either) and also (we think) the bathroom radiators. The bathroom radiators were working for the first few weeks, then stopped for a few days, then started again for no apparent reason, then stopped, then came on one morning but have now stopped again and have not come on for four days. I have vented them, they had some air in them, but are still completely cold. The boiler is run off an electronic timer, which seems to operate correctly, the heating symbol and the hot water symbol both come on on the boiler. Any ideas?

Radiators work some days and not others...
