hi can someone please tell me whats the best kind of combination boiler to get for reliability and most powerful thanks
A bit of a contradiction that one. Must be a joke question
The old Vokera SP was not too bad but unfortunately they have stopped making them. If you wanted to go for a regular boiler then an E Type or a Mexico (not the FF one) but they have stopped making them too.
Joking aside, whatever you choose, every make, you will need deep pockets to fix it over it's short lifetime so as PVM says go for a long guarantee and at least the first 5 years are covered.
Bet your old boiler has given good service with only a few niggles over the years. Don't think for a minute they still make them like that.
Personally i fit Vaillants (2 yrs)or WB (2yrs but up to 5) because i like the Vaillants (easy to fit and fix) and the custs like the WB (the woman next door has one and it looks nice). These boilers sell themselves because of the public's perception of them. If you are skint i recommend a cheap Vokera easy to sell in west of Scotland because of their previous good rep. (Sabre £30 cheaper same blr). Pay your money take your chance!
Boilers can be a bit like cars. Do you go for the Kia at 6K, 5 yr warranty and drive it with a balaklava on or buy the beemer for 30K and polish it every Sunday to impress the neighbours? Which one would be most reliable? At the end of the day they will both get you where you want to go but you buy to suit your budget. Difference is do you really need to impress the neighbours with a boiler?
What is the point of spending an extra 2K on an installation with all the bits to save £100 a year? Thats a 20 year payback and your new boiler will be lucky to last 10 years!
In my own house i have got an Ariston???(dunno, some system one, it's in the attic and i have never been near it for 3 years). Not a personal choice or one that i fit but i knew the rep and got it for £100. It works fine and gives me plenty heat and water and i have never seen it since i put it in. First time it coughs and i can't fix it with what i have in the van (in under 30 minutes) it will be in the skip and i'll stick in whatever else i can pick up cheap.
If it was me i would go for any cheap boiler with the std pipe layout FHGCR then it is easy and cheaply swapped in the future.
You may have noticed i am not trying to sell you on anything. Just giving you an honest opinion.
