Vokerra -hot water only warm??

[jill30]

Hi guys. I need your advice

I have a Vokerra combi. The central heating is working fine. However, its taking the hot water a while to heat up. It reaches temp after about a minute. Been like this for a couple of weeks.

Is the water hot only when the heating is on? Diaphragm needs replacing.

Do the radiators get hot when hot tap is on? Diverter valve stuck and needs replacing or servicing

Thanks gas4you.

In answer -no

Put the C/H on and its fine. Radiators are nice and hot. Turn off C/H and they stay cold.

Run a hot tap and after a few minutes its hot. I have felt the C/H pipes when running hot water and they stay cold (amazing what you can learn on this site)

Could it be a faulty electrical thermastor (thing)-oops

Could be, but unless you are in front of it it is hard to inform you precisely. Can you check resistance values etc. Could also be simple as in gas pressure has dropped due to govenor fault. I would recommend a pro visit you.
