We have a glow worm micron 50ff boiler in the kitchen for the water/heating and a hot water tank upstairs. the heating has stopped working but the hot water is fine.
Tried switching off and on, etc.
Is it the pressure? i cant see any pressure gauge anywhere or where to top it up if it is. absolutely nothing next to the boiler or up in the cupboard where the tank is looks like a pressure gauge. there's a few valves but i've no idea if one of them tops up the heating.
i've checked a couple of the radiators for an air lock and dont seem to have one, could it be that and i'll have to check them all?

If boiler fires for water then the pressure should be fine. Possibly the motorised valve not engaging the heating??? Someone who knows more will probably be able to diagnose better.
 
As myself is a plumber, as a matter of fact, there’s no pressure gauge valve on gravity fed system. It sounds like the Zone valve are not working.

I don't know how mechanically/ DIY competent you are? but on some of the older valves you used to be able to move it manually. ie you move it across to heating, but then have to remember to move it back to heat your water.

Disclaimer- if you are useless at such things, don't touch it.
 
Do you have a motorised zone valve like this?

The motor may have given up, they don't last forever, or the valve may have seized. They usually have a manual lever to open the valve if the motor is gone (small level of the front of the image above).

If the valve itself has seized then you're probably going to need a plumber.
 
Easy to replace!

Easy to replace! Screw head off and put wiring in the same as the previous head

look like you can just pop off the motor and turn the actual valve on the pipe manually. might work till i get it fixed

well me heating is on. the lever did push over i was just a bit reticent to force it and its working. doubt it'll push back now seems completely stuck so i'll have to pop the motor off and turn it back with pliers i think to get hot water on.
cheers all.

A while ago mine stuck, take the top off the housing use a Flathead screwdriver to push it across, spray it some Wd40 or similar, eventually it freed itself.
Worth a try.
