Help needed please ! Vaillant boiler hot water but no heating

[coldinwales]

Hi,

dont know if I am posting in the right place - but looking for some help if possible please.

Have Vaillant combi boiler approx 4 years old.

Hot water has been a bit slow in the mornings then comes out brown, then works fine.
Electric shower blew at the weekend - think this is the pressure release valve (triton). Went into loft checked lagging on all pipes and turned off shower at stoplock in loft - left slightly dripping to prevent freezing. Checked central heating pipes lagging seemed ok.

Now no heating at all - but still have hot water (not brown).

Have tried to get out both plumber and / or Corgi but not able to come for a few days.
Any advice as to what I can do in the meantime ?

Does it sound like an airlock, frozen pipes, sludge in the system, broken divertor valve in boiler or something else that googleplumber cannot spot ?

Have small kids getting cold - so any advice welcome please.

could it be anything to do with the stoplock you turned off in the loft? turn it back on to see if the heating comes back on (long shot)

Thanks for considering my problem I will give it a try. Only problem that I can forsee is that
I will then have high pressure cold water pouring out of the shower unit. Stoplock tap thing has been turned off for a day or two - heating only stopped today.

Wondered if the brown sludge dirty water has somehow nixed the boilers central heating bit but not the hot water bit. Sorry - you can tell Im not technical !
