Boiler upgrade options

[Deleted member 120897]

Ok thanks, so sounds like best of both worlds in terms of operation but perhaps more complex and costly as would need new combi boiler and sealed cylinder. Although I don't like electric showers, wonder if having one electric isn't bad idea though in case boiler goes down.

They’re a good idea as a backup. I work in social housing and the vast majority of our properties have an electric shower, I think this may have been the reasoning behind it.

Hot water from the vented cylinder is main issue or lack of it, doesn't get hot enough. Also have large cold water tank in attic feeding cylinder and want rid of it, this is in addition to vented expansion tank in attic.

What’s the cylinder thermostat set to? Has it been checked it’s working correctly? Is it connected to the cylinder correctly? Ha so the motorised valve(s) been checked?

It doesn't have a thermostat and the cylinder heats if the heating is on there is no separation so it's a bit of a mess. And apparently it has 10mm input pipe and been told it's just not been done correctly so it either goes completely in case of combi or swap for new sealed. Another caveat is that we're having a rewire soon so floors will be up making possibility to change all pipes which paves the way for heat pump in future but generally at least 15mm is probably better than 8mm! Which is what we have now
