new boiler, which system?

[hotncold]

I am thinking about changing the boiler this year, currently an old Spacesaver 38 (S Plan).
Talked to one company last week and told him that I didn't want a Combi but that as I live in a flat there is virtually no head ref the F& E tank.
He was talking about fitting an expansion vessell into the system instead (but not a system boiler).
Does this make any sense, would it be worth considering?
Any help, thanks.

Go for a combi, they are superb for flats. Get a quality high flowrate model. Atmos, ACV (both v good), Viessmann, Atag. At a push, Worcester, Vaillant, Keston Qudos. Avoid Baxi, Potterton, Ideal.

Indeed they are, but the OP doesn't want a combi.

had a combi before in a previous flat & I agree they are very good but there is more to go wrong and if they do break down you are left with no heating or HW plus other factors as well.

Your concerns are understandable but problems are rare with combis installed and maintained by someone who specialises in a particular brand. You can have a regular boiler with a separate sealed system kit provided the pipework and fittings are in good order.

It clear he doesn't know and is going on old wives tales. Now he knows and what to do and what products. Great eh?

The OP has a concern which is well founded by many people who have a combi installed by a fit it & scarper merchant. This is why the OP is advised that a combi installed and maintained by a specialist is worthwhile.

However he/she does not want a combi, so cannot be forced. To put it in language you might understand, imagine, Drivel, you were on one of your wife-finding trips to Bangkok and were supplied with a woman instead of the ladyboy you'd specified.

Blimey, what a can of worms I've opened

Not at all, it's a simple request for the feasibility of a regular boiler with a sealed system kit in a flat.

Just a metaphor used to illustrate your request to Drivel.

Take no notice he is from Essex. Bald head, tattoos, larger louting, etc. Sad but true.

When they revert to insults you know they are wrong. Sad but true.

im sure a good engineer will be able to design and install a system to suit your requirements. Not everyone is a fan of combi's, they serve a purpose but some prefer stored hot water, with the addition of an immersion to provide back up in case of boiler breakdown.

As Nixt said, a boiler could be installed on a sealed system if required. Using a conventional boiler, expansion vessel, safety valve, pressure gauge etc, the system can be converted to sealed operation. This would negate need for a F+E cistern, thus satisfying your requirements.

Subject to your mains water pressure/flow (dare I say it?) there is the option for unvented hot water, which again would negate your need for a storage cistern or a 'Fortic' type cylinder in the flat, giving better flow at hot taps.

...... I see......

Take no notice, I was wrong......... That picture Agile posted of Drivel bears a resemblance to a disgraced former Glam-Rock idol. So it must have been Vietnam.

Drivel, you say use the high flowrate models Atmos and ACV, which one would these be.
