Why should there be any difference?

Theres no difference in terms of gas use. I think one of them just provides hot water quicker as its stored within and the other doesnt.

Let's see, keep firing up once in while to keep 15 litres on the boil, or not. Hmm?

heyyy thanks for the reply i have tried cant find a specific answer! i rang vaillant today and was speakin to a sales staff she said the ecotec plus 937 system boiler will automatically store hot water i said but cant it be turned off she said no so i said not exactly energy efficent then is it than she said u can purchase a timeswitch 140 which will allow u to programme when u wnt the hot water to be stored! the programme itself cost £50 wonder is thats worth it what do u think?

In the mornin theres a rush hour for the bathroom as we all get ready to go for work with 2 bathrooms in the house we have to quickly off the water so the person upstairs can get it hence why i thought of getin the 937.

You have two bathrooms? You need a HE system boiler and retain your hot water cylinder.

You would need a system/regular boiler for 2 bathrooms as a combi can only provide hot water at one tap at a time with the others getting a small flow of hot water

You mean a hot water cylinder, which can be heated by any kind of boiler, including combi. A system/regular boiler only does central heaing, strictly speaking.
