Am I going mad on this?

[cr0ft]

Hi all,

I've just had a gas fitter round tonight who is going to be fitting the boiler for us on this property renovation job. The cylinder which is going to remain is a new open vented indirect cylinder. I want to fit a system boiler in the loft which will obviously remove the need for the F/E cistern. This will heat the water in the cylinder. The heating circuit will obviously be pressurised and we will run completely new pipework throughout the house for it.

The gas fitter didn't seem sure that a system boiler can be run on an open vented cylinder. My response was 'of course it can, the coils are built to withstand the pressure'. Is he right or am I? I am sure I have seen this setup before with just a CWSC in the loft feeding the hot water cylinder.

Am I going mad? He's got me doubting myself.

Dont understand why eeediots think just because the boiler is pressurised your hot water tank has to be aswell,,, if i were you i wouldnt be allowing someone who didnt understand something as simple as that to work on any of my installs,, fair enough if its a simple brain fart he had as we all get one from time to time ,,




thats ment to be a brain fart lol

your gas man is wrong,or stupid but definitely both ,you can even connect a combi to a cylinder provided you know what your doing,most combis are cheaper to buy than system boilers you just need one hot tap off the combi
