boiler to choose

[parekr]

I desparately need advice from pros regarding choosing a replacement boiler for my CH system. Hot water is available by indirect heating ( hot water cylinder).
I currently have a Baxi back boiler + fire in chimney breast which I understand is about 25 yrs old.It is working fine apart from the pilot light going out occassionally. But I understand its spares are getting difficult to obtain as time passes.
I have been hearing/reading adverse reports & problems associated with new Combi boilers ( specially with electronics failing). iIwas advised that I need to choose between 2 options:-
1. replace current boiler with new Baxi back boiler but the new regulations require vent from boiler to FE tank to be higher than the height of the boiler. This would mean the new vent pipes to be above the floor boards. Also the efficiency of back boiler is about 78%. But the boilers are less complicated than the Combis.

2. A system boiler and keeping the hot water cylinder.Efficiency is 90% +
Responses from experienced gas gurus would be very appreciated

HI

i recommend system boiler. you can also upgrade your cylinder to
Higher Effeciency.And with gas prices going up it is good to store HW.
and like you said combis are more complicated.

You have to have a condensing boiler so you cant have another back boiler !!!

All new boilers have a lot more in them to go wrong, just like cars these days... A system boiler will have dearer running costs than a combi and if it is fitted correctly and serviced regularl then there is no reason why it shouldnt last .... I personally would look at Viessman or Worcester Bosch !!

Would you care to elaborate the reasoning behind your advice? Or did you just make it up?
