Repressurising Saunier Duval Thema F23E

[imroberts]

Just moved into an apartment which has one of the above boilers. While it is working fine and I am very happy, the pressure gauge is down at about 0.5bar rather than ~1.0bar as it should be.

Last place I lived in had a Potterton boiler that just had a valve on the front to repressurise it, is it this simple with my new boiler or if not, how is it done?

 

[Dan Robinson]

It is that simple for yours to; but I would put a bucket under it to catch all the water that p1sses out of this piece of Frenchman's feaces.

I'm sure Sauny released this one as a joke on the Brits...

 

[imroberts]

Where is this valve located?

Dunno - my psychic powers only operate 08:30 to 17:00 Monday to Friday.

I hate SD's

Sorry matey but you have a shed of a boiler

Fair enough. But I still want to know how to represurise it

look for a silver hose connected to two taps

or do a search on "filling loops"

as Far as I can remember these heaps dont have an integral filling loops

All the pipes underneath are solid except for one flexible silver hose... would this be the filling loop? I assumed it was the gas connector!

So much for searching then

CM £50; no tah... its £70+VAT.

I read the sticky on filling loops, pretty much matches my boiler except I only have a valve on one end of the flexible hose.

I opened this valve for what seemed like an age, and could hear water flowing, then it seemed to stop and the boiler started 'gurgling' so I turned the valve off again. This barely moved the pressure though operated the heating for a few minutes but it still didn't really increase hugely. How long should I expect for the pressure to increase from ~0.5 bar to 1.0-1.5 bar?

Any suggestions before I call out a pro?

Depending on the size of the system and the accuracy of the guage, quite a while.

Check that the safety pipe is not discharging outside.

By quite a while are we talking minutes?

I checked the boiler just now and the pressure seems to have dropped to 0.5 bar again... gauge is in exactly the same position as yesterday before I tried to refill it

I also hate these boilers!

They are the only model I really hate and thats partly as a result of the attitude of the company in charging installers 50p per minute for bad advice after a five minute wait ( costing £2.50 ) !

Having said that I do understand them pretty well.

It might take several minutes depending on the water supply pressure and the size of the system and the amount of air in the rads.

Hmm, might give it another shot before I call someone out I certainly didn't leave it for several minutes and having bled the radiators since then there was an awful lot of air came out, so it might just have been me being impatient
