Vaillant System Boiler and Megaflow Installation

[Tiara]

Hello,
I have open vent old Ideal boiler (in the kitchen)with open vent hot water cylinder.(on first floor cabinet)
We would like to change the boiler to Vaillant Ecotec Plus 624 system boiler and 210i unvented indirect Megaflow cyclinder.
How much it will cost the labour? How long it will take to install them?
Anyone has unvented cylinder ticket and possibly approved Vaillant installer.
Thanks

Best to get some quotes and I would say 4-5 days depending on what you want

Is this someth you’ve just decide, or have you had some investigation work carried out already? For example incoming cold mains pressure or the flow rate of your cold water? These are generally necessary for swapping to an unvented cylinder.
