I probably owe you all a beer, radiators and pipes still stone cold though, but maybe will take a bit longer than they did before since they haven't been warm for a few days
The pilot has not gone out through whole process, I have pulled that grey knob fully up, programmer on, which resulted in a firing up noise. will check radiators again in ten minutes. Thanks for the thoughts so far everyone
Do you think it's worth turning the boiler itself completely off and letting it cool down before messing with everything again? Not sure what order to do things in
I can't find anything else around the boiler or other parts shown in the pictures, the only other parts I can see are another bigger, black water tank next to the one shown, and the room thermostat dial
The whole system looks a bit patchy tbh. I get the general feeling the landlord isn't terribly keen to bust a lot of money on it... definitely some bad design features here. For eg, shower on/off switch seems to be hidden in the walls somewhere, if there is one that is!
Thanks for the tips so far, it's very good to know the make of programmer at last (been hunting online all day for that info). The whole system is still making a lot of noise, which seems curious...
