We're about to have an extension built, which will necessitate the installation of a new boiler, (and cylinder). I am considering installing Solar DHW as well, (or at least installing a dual coil cylinder to enable that upgrade in the future.). A couple of quiet nightshifts and an awful lot of googling of this group suggests that I don't want a combi, (please no discussion of this; I see that it's been done to death one hundred times before!), so thought that I need a traditional vented DHW and cylinder system. However, the overwhelming opinion in this group seems to be that that is soooooo yesterday, and what I really need is a heatbank or thermal store.
What I don't understand though is why I need a thermal store in the first place rather than just a 'traditional' vented system. My understanding of the advantages are; mains pressure hot water and.........
Is that all I get for the extra expense of a thermal store?
Of course I know I get the advantage of being 'hip and with it' and not using yesterdays technology, but when the system goes wrong and I need to find a plumber on a bank holiday weekend, (sacralidge to say of course this being a diy group!), is it such a bad thing being a dinosaur?
Hellllllllp
