Looking to replace a small old combi boiler

[graumsmith]

Hi there. I have recently moved into a new house. The boiler is in the kitchen in a cupboard and is by all accounts an Ariston Micro Genus 27 MFFI. The boiler, we think was installed when the house was built approximately 10 years ago. It is very noisy and seems to fire up all the time. we have budgeted for replacing it as was strongly recommended by the surveyor. The house is smallish with two bedrooms, living/dinning room a small closet toilet downstairs and small bathroom upstairs. there are 6 radiators in the house the largest of which is a 600x1400 double in the living room.
i'm looking to replace the boiler. the current dimensions are 700hx400wx300d
my plumber friend has had a look and come up with an Ideal Independent C combi.
but rummaging through the other forum posts i'm not getting such a good vibe about Ideal boilers generally. and this model seems to be a bit out of date also.
the most important thing really is reliability and i don't mind spending a little bit more in order to get it. (£600+)
From the other posts, i have noticed that the most recomended small boilers are Remeha Avanta or a Vaillant of some kind although not sure if these will fit...
i understand that the reliability of any boiler is mostly down to installation but it would be good to get something that is well recommended firstly and also in the event of it breaking down that the parts are easily accessible and fittable.
any advice would be really helpful
i hope i have given you all the information i can
thank you all very much in advance for your help
best Graham

The current Ideal combi is the Logic which seems fairly reliable and they are easy to fit.

I always recommend fitting a boiler a size larger as a 24kW is struggling in cold weather.

Best value for money would be a Viessmann; good boiler, good warrantee.
Remeha seems to be ok too, but I doubt you get the same 5 year full warrantee.
Vailant is not a bad boiler, but they have the worst after sales service of any brand you can buy these days.
Ideal is arguably the worst brand on the market, stay well away from it.

A "plumber" who recommends the model like you quoted should be viewed with suspicion. Is he a plumber, or a heating engineer?

Vaillant ecotec pro 24. Vaillants are the best on the market and this one will do you well

Of course it seems reliable, it's only been on the market for about five minutes...

If you want a physically small boiler you won't be looking at an ecotec

intergas hre 28 would be just the ticket, the size is(with out flue, trap and exp vessel):
Height 650
Width 450
Depth 240

with the 24kw intergas being the same size but with a height of 590mm
