Replacing a Keston K130 boiler need recommendations

[John99]

I'm replacing a Keston K130 boiler (max output 42.3 kw) and I could do with some recommended condensing boilers for a sealed system. Looking for reliability and quietness of operation given the obvious and well-known shortcomings of the current appliance. Serves a 2 storey, 5 bed property of 4000 square feet.

cheers,

John

Atag Q38 would cope unless you really need 42kw and then you could then go to Q51. Alternative would be Viessmann, but don't have experience of their bigger rated boilers.

Both have weather compensation controllers and 5 year warranty and 10 years on the main heat exchanger. I think Keston give a 2 paltry years on their heat exchangers!

Worcester Bosch 40 CDI.

Five year warranty and 4 years WB servicing if install done by a WB AI

Viessmann 200 46Kw. Sit one next to a Worcester 40 and weep.

How about a vaillant ecotec 46?

Any good to replace a k130?

intergas hre 40 or if you want a bit of back up 2 intergas 24kw boilers.

I'm tempted to try a viessman 200 are they really good?

I'd stick a valiant in there.

Kestons are normally used when its difficult to run the flue, how is your boiler located ie in a basement or middle of the house ?

The ecotec 46 is a commercial boiler and so the installer also has to be suitably qualified.

Atag Q38 all the way. Far better than the Worcester.

You should use the Whole House Boiler Size Calculator to find out what size boiler you really need.

PS 4000 sq ft is very large - approx 50ft x 40ft footprint - are you sure you worked it out correctly?

Fair enough, would just be clearer if you had your own thread with all the details as it can get confusing
