Water tanks located in the middle of first floor, I'd like to remove them, what are my options?

[RFw3Duwrd7Yu]

I'm renovating an 1880s semi-terraced 5BR house. Much of it is still original, with some rooms lacking power outlets. One thing which has been "updated" has been the installation of radiators, and a combi-boiler (located in a back stairwell on the ground floor, see photo).

However, there are still a hot water tank and cold water basin which are in a cabinet in the corner of one of the bedrooms and happen to be taking up quite a lot of real estate on the first floor (roughly in the middle of the house).

Ideally, I'd like to remove these two tanks and demo the structure so I can use the whole room they're in, but this is new territory for me, so I'm a bit unsure about what my goal should be here in terms of renovation. Is there an option to replace the boiler so that hot water can be "tankless" and relocate the cold water basin to the attic? Should I try to relocate both? Am I stuck with this configuration? Usage will not be terribly high - we will have 4-5 taps in the house and two toilets but only one bath/shower combo, so potentially will not be using that much water at a time. All tips welcome!

The tanks remain because you don’t have a combi boiler. Looks like a Worcester ri. If you want rid, then you’d have to upgrade to a combi/conversion.

Ah, ok! So new combi-boiler means that I can ditch that hot water tank. That seems sensible. But what about the cold water cistern above?

Sorry, what about it? If you converted to a combi (mains water pressure and flow rates permitting) you’d get rid of all tanks, hot and cold, and small feed and expansion/header tank.

Fab - that's what I was wondering. Obviously a newbie @ plumbing here. Seems like it's time to go get some quotes on combi boilers...

Careful, have you ever used a combi boiler before? You can really only use one hot water outlet at a time.

That and your system seems to be open vented, going to a combi will usually mean converting your low pressure system to a sealed system (boiler make dependent) with the possible complications/cost that could entail.

It's rarely as simple as just slotting in a combi and hauling the cold and F&E cisterns out.
