pipe work for new boiler help choice of boiler

[chris 600]

Hello everyone

I am thinking of purchasing a baisi boiler (condensing 30kw)
firstly are these any good
secondly the house i am buying has a back boiler which i intend to change with this (new one is going in kitchen the old one will be capped the only reason is i think it would be a pain i think. any advice on the location )
the problem i have is some of the pipe work to the rads is 8mm and some is 10mm. i am no 100% on what the flow and return is, i think its 22mm. i read something on restrcitions on pipe size when going over a certian kw boiler. could anyone tell me what they are? i am only doing the water gas will be done by a pro, obviously. any advice would greatly appreciated
cheers chris

First of all forget using a biasi (they are just cheap & unreliable) if i were you i would change complete system using a vaillant ecomax or a worcester bosch unless you intend doing house up & moving within 2 years

Cheers for your advice weareleeds
do you think i would be better off putting new boiler in the kitchen?
i dont know how much of a pain it would to put in where the other one is or up stairs where the tank is?
cheers .

Good advice from weareleeds, buy yourself a decent mid range boiler.

Putting the boiler in the kitchen is preferable as it eliminates the dead leg for your hot water to the kitchen sink.

Cheap, yes, but unreliable? Not in my limited experience. I think they represent good value for money. A much more expensive boiler won't necessarily give you better reliability.

As for 8mm and 10mm tube, don't worry about this, it's probably fine.
