First, thank you so much everyone who helped me understand about my three port valve; I'm going to have to get a pro in to have a look at it because I now think that my hot water not coming on could be one of two or three things - how about you? It might be the pump (but then the rads wouldn't get hot, or, the cylinder thermostat as if this is broken or perhaps needs cleaning it might not signal to heat the water tank?
Please too can anyone help with what this is!!! (picture below) Hugh said he though it might be an automatic vent or a bleed?
If it is a auto vent do I need to open it periodically or anything, like when I bleed the rads? I'm enjoying finding out about these things. Thank you all
