What is the cheapest way for me to replace my boiler. I want to replace only the boiler with a similar one at minimal costs.

Basically taking out the existing and replacing with a similar one. My existing boiler is an Ariston Euro Combi Boiler (model: SX20 MFFICE)?

I have kept the filling loop open slightly, cause if i close it fully then the pressure goes down to below 1.5bar and the entire system stop working. The pressure has to be above the red marker which is at 1.5 bar for it to work.

if it keeps going back up your filling loop isn't letting water by is it.

The leak is now coming from behind the pump. Probarbly need to tighten the bolt. I have reduced the pressure to 1.5 bar, but it goes back up..
Can this leak be due to the radiators not heating proparly? That would explain why, whenever i fix one leak, another evolves.

which any descent rgi won't do . commission other peoples work.

Fit the new boiler yourself then get a heating engineer to come and run the gas pipe and comission the boiler for you?

have they sorted this leak out ? if your pressure is kept 1 / 1.5 bar theres not a prob. i can't see why they can't balance it for you. ( mind you there is some thick so called plumbers out there, don't no how they get by.......)

Well, there is now another leak coming from the boiler. I have fixed the previous 2. I am worried that eventually the pipes will burst.
I am still convice that it's a matter of re-balancing the pressure in the system, but i just cannot do it, and the 3rd supposedly engineers have come out, and i know more about the boiler than they do. So not much help there, cannot keep paying for service charge whenever they come out. I have already spent £250/-.

I still believe that my boiler can be fixed. But need someone who genuinely know what they are doing.
