Combi Cylinder

[nogoodatfaultfinding]

Right folks,

Gone to a heating system today total upstairs heating pipework dry and pump making a right row.
I have never came accross this cylinder before but believe the built in header feeds both the CH and HW and is most likely the type with a bubble in it if you know what i mean.

My question is am i better to cap the CH Feed off and add a Header Tank or try and Back Fill the sytem as i am aware this works on the old type with the Cardboard around it.

Please note that the Combined Header Tank still fills the HW no problem.

Thanks

Charles

If you talking about a Primatic cylinder it wouldnt be a pumped system would it?

Aint got a clue mate like i said ive never seen this setup before, i initially thought that it must be some sort of weard sealed system setup but after hunting every room in the house could find no way to fill the system so assumed it was like a primatic, defo no headers or filling loop, seems to be a secondry feed from the built in header to the flow which is not working, tried the old magnet but theres no blockage that i can see (if you get my meaning), im sure when with council that i ripped out loads of primatics on classics with pumped systems but thats the reason im asking you guys.

Thanks for response

You cant pump a primatic on the HW side, only on the CH

Sorry mate when i said the HW was working i mean that the ball valve and combi tank refill the cylinder when a HW tap is opened in the top of this built in header there is also a cylindrical 4" wide seperate thing that goes nearly all the way to the bottom if that helps where the CH feed seems to be

Sounds like a fortic primatic, take it there no other headers anywhere else, drop some ch water from a drain off and see if cylinder fills from same header as hot water does

It took me a minute to figure out what you were talking about

you have an elson tank, they can be very difficult to clear when the ch feed blocks, sometimes your lucky and sometimes you aint, try back feeding it from the mains.

Thats what i thought as my above post, is it possible to cut out the cylinder feed and attach a Header tank, wont be breaking any regs doing that will i?

Nice one picasso never heard of 1, how do they work mate?

I got it wrong mate I seen the mention of the cardboard and jumped to the conclusion you had an elson.

if a primatic wont fill the system its "donald ducked"

fitting a header tank will acheive the grand total of jack

other option is remove it and fill it with DS3

all you will be doing your way is filling a direct cylinder which will scale the lot up

btw tha cardboard covered ones are elsons

sorry if i came across as sharp

Thank you very much but still dont get why a header wont achieve what the combined header was?
Is it not a little early to be drinking if your in the states
