combi v mains pressure system

deejkal

Thoughts and opinions most welcome......

Am wanting to install a central heating/hot water system to my house. House is currently a bungalow with a very big loft soon to become a second floor. Will have a downstairs shower room/toilet and one 4 piece bathroom on second floor.

Problem is, which system to go for - space is tricky but not unsolveable. Have come from a megaflow, pucker kit, but did have exceptional mains pressure 8bar+++. Now have 2 bar, 20l/min. I know megaflow do an eco cylinder which works well (they say) down to 1 bar. But would a combi do the job? Don't want interrupted flow and want decent shower with possibility of having both showers running at the same time. One plumber has suggested that if the showers are plumbed in separately won't get interrupted flow

Also....... another plumber has suggested a horizontal cylinder (mains pressure - not megaflow - cos they don't make one). Can't find much info on them, but a couple of forums have raised an issue with water stratification - understand what that is in principle, but not practically how it manifests as a problem.

Leaving aside the flow problems, I very much doubt if any combi will heat sufficient water for two showers; most have difficulty in providing a decent shower for one in winter when the mains water is cold.

I would always advise that any combi won't be suitable for 2 showers running together and achieving a good shower.

Thanks both, any thoughts on the horizontal cylinder and water stratification thing? When you say "leaving aside the flow issues", do those stats raise problems for either system please?
