hi all,
been trawling through the search engines for two days and decided I know less about the options I have than when I started.
The Problem: I currently have an open vented heated system, that is under speced from the boiler point of view and I am trying to suss out what is the best road map to change the system to what I want without ripping it all out in one go as I can not afford it.
Main issues to be sorted are: When the heating system runs the overflow overflows constantly Hot water is at too low pressure I would like to add a radiator in the loft at some point as it is a walk in room
Solutions ?
I am thinking that using a thermal store will give me the mains pressure hot water I want while still using the open vented system Installing an airseperator from what I read on the net should stop the overflow issue, but not found one that I can buy convert the system at a later date to either a closed system or buy a boiler that is already a closed system to get the hot water in the loft. Can you get such boilers that are not combi boilers or do I need to install the parts. If that's the case, do I need to put the expansion vessel near the boiler and hence in the kitchen..
How would others tackle the problem ? useful urls for suppliers like the air vent would be welcome, the ones I have found seem to be targeted at just removing the air
many thanks and cheers
