Warm & Cozy but no hot water!

[MissND]

HI,
Hope someone can help.
I have an Ferroli Optima 701, since I bled all the radiators I have found that I have no hot water. The heating is fine, but the water runs warm for about 10 seconds then goes cold.
Should I bleed all the radiators again?
Any suggestions will be much appreciated.......

Thanx

Miss

i am not a plumber or heating engineer, so i am not familaiar with your boiler, but do you have a tamk or two in the loft?

if so go and see are they both full of water, reading these forums, sometimes the ball valve gets stuck in the level position and stops the system being refilled.

good luck

Boiler is combination. No big or small tanks in loft.

You do not need to bleed radiators. As you will already have noticed, no air comes out when you vent the radiators.

You will need to call out a HEATING engineer to look at the boiler. I would suspect HW sensor to be the culprit.
