keston celsius c25

[ingrid]

Hi. I've noticed a few posts on this site on keston boilers so thought i'd join in the debate!

I'm currently upgrading my central heating system and the plumber I've always used has recommended a keston celsius c25. If its any help to whoever asked, he assures me that it will be reliable and that he has had very few problems with them and that he now instals large numbers of them every year. He also said that, whilst they cost a little more that some others on the market because they are a lot easier to fit, it'll take him less time on the job and so actually cost less in the long run

One thing I wouldn't mind some advice from you guys on, tho. ....

I live in a large 4 bedroom house (with 1 bath and 1 separate WC), and I plan to have a loft conversion added in the next few years, which will take it to 5/6 bedroom, 2 bathroom, 1 WC.

He seemed to think that the Celsius boiler would do the job for any size house.

But he did say that I could go for the next model up (the C40 he called it). He thought this boiler is mainly used for commercial work but that it could be used for larger houses too. So now a little confused

He was pretty clear that the smaller boiler would do the job.

But can this really be the best solution if it's the kind of boiler which he says he regulary installs in small flats? (let alone larger houses).

And won't it be inefficient to be running a 'smaller' boiler at full capacity

Any ideas guys

C25/C40

thanks

tell him no, stick with the more popular models, worcester vaillant potterton baxi etc, if nothing else it will be easier to get parts, ow and no condencing boilrs

I dont trust anything which comes with photocopy instructions and no user information with a reset button hidden "inside" the casing, I agee with shaneo.

25kW could be getting marginal if the house is detached and oldish so not too well insulated, especially if you have a decent hot water system which expects a lot from a boiler. Sure there's a C40, but there are others like the Worcester Bosch 40kW which is cheaper.

There's a 40 too!

Hey, thanks guys

He said it should really be either one of the two he's suggested as they are much easier to fit in awkward areas (I'm going to get him to put it in the basement level). So I'm decided on that already and I trust him to be giving me genuine advice on that front.

Interesting. Firstly, so do you think the C25 may not be powerful enough, and I should go for the C40? House isn't detached unfortunately but it is quite big.

Secondly, he says there's £500 difference in the price between them. Seem about right?

Thanks guys

can your plumber maintain your boiler after warranty period,if not what ever boiler you chose get manufactures service contract for boiler only.
new boilers are like some cars,very specialist,not everyone will work on unusal boilers.good luck.(did you win the lottery)

" so do you think the C25 may not be powerful enough"

well you do need to get it right! He should have added up all the current or prospective rads, and discussed HW needs with you. If you ever get a Megaflo type HW cylinder, they need 25kW by themselves for minimum reheat time, though it was the tradition ot allow only 3 kW in the sums.

Kestons DO have extremely flexible flue systems which may preclude others.

ChrisR - good point. forgot to say earlier but part of the job also includes fitting a great big new mega-flow hot water cylinder to run the hot water for the whole house. Does that effictively take the c25 out of the running? Go for the c40??? Grateful for your views....

Can't help thinking:- will a commercial boiler really be appropriate for a residentail house.

Thanks muchly guys

Guys,

In view of:

25kW could be getting marginal if the house is detached and oldish so not too well insulated, especially if you have a decent hot water system which expects a lot from a boiler.

And the fact that I will also be having a mega-flow fitted to a large-ish house, does anyone else have any views on whether to go for the more powerful C40 over the C25?

Any other disadvantages in going for the C40 (other than the initial outlay)?

Thanks,

ANything up to 60-70kW is still "domestic". I stuck a Keston 55 in a biggish house with a monster Megaflo without real issues. It isn't particularly quiet, but isn't a nuisance to the owner. Should be OK in a basement.

Told you if you want a good boiler click on the MHS link and look up Strata Streamline, as quite as a church mouse.

Not cheap but then you get what you pay for.

Keston Celsius has been around a LOT longer than many of the other condensing boilers mentioned. IMHO, the bugs are out of it and (so far) I've never had one that failed to work as advertised!
The point no-one made yet is that your heating engineer (plumber?!) seems not ot have done a sizing calculation to match boiler to load. He needs to. The fact that the Celsius is fully-modulating and also adjusts pump speed means it will match to quite a range of demand but it's still only 25kW. (Having said that, most of the time and in most weather conditions one of mine (out of 2) handles a bigger load than 4 beds and a Megaflow but 5 / 6 beds would be a stretch.)
