We have a Siemens RDJ10 thermostat controlling the times when our Glowworm boiler is switched on/off for the central heating.
As we've just started putting our central heating on, we've noticed that the boiler no longer switches on or off at the programmed times. We need to switch it off/on using the dial on the thermostat. The boiler and thermostat worked correctly all of last autumn/winter.
Earlier this summer we had a different problem with the boiler, whereby the water from the shower would suddenly go cold, and then heat up again after a minute or so. We called a plumber out, and he fitted a new heat exchanger. However, this did not solve the problem, so we called him back and he changed another part (not sure which) and that solved the problem. Now we have this new problem.
Could this have been caused by the plumber not fitting a part properly or not putting the system back together properly? We have just got a £400 bill from him for fitting the two parts Should we call him back and get him to sort this new problem out or get a different plumber?
We've also noticed, that since starting to put the heating on that the boiler occasionally drips from somewhere inside, and it keeps losing the pressure - it should be set at 1.0 bar, but it keeps dropping below that and I have to re-pressurize it.
