ideal logic plus or ideal vogue

[Jimbob]

You really can't go wrong with the logic +. I'm a big fan. Really easy to install and commission and it's a really smart looking boiler. Haven't had chance to fit the vogue, but would like to.

The new baxis are ment to be good ( now problems are solved) but can't comment personally.

Stay away from glow worm, Baxi duo tec isn't a bad boiler for the price and comes with 7 years. I would go with the logic though.

Ash, here's my concern.

You need your installer to PROPERLY SIZE the boiler to suit your hot water requirements. It's pointless saying your committing to a logic 30kw boiler if you need a boiler to provide 16l/m. The fact your installer seems to have offered you 3 different boiler sizes OR he's letting you decide, says to me he doesn't know/care about what he's doing.

I would say logic and duo are on level pegging. Logic is smarter looking and more compact yet still nice to service / repair . From what u have said 30 logic + or 28 duotec DO NOT GET A DUO TEC GA or NETATEC GA !!!!! B

I understand where you are coming from, the plumber suggested 3 sizes on the basis of the following

ideal logic 24 would be suitable for a shower, occasional use for baths
ideal logic 30 would be suitable for baths
ideal vogue slightly better flow rate than the logic 24, but again occasional use for bath too

i am also thinkng whether the ideal logic 30 would be oversized for my requirements? and would "cycle" due to it being oversized?

Hmmm

I would always offer different sizes as price varies loads. When doing so I educate them on the difference, which is DHW flow rate. And more is better in nearly every case when it comes to combis, but it comes at a cost. It's not like sizing an unvented system where your sizing storage

So am i good to purchase the logic 30 plus? and not have issues with cycling due to modulation?

Yes. However, I would recommend letting your installer buy it and supply it, even if he marks it up a little. Then there is absolutely no question about who is responsible if there are any issues.

If you buy it (saving yourself a couple of quid perhaps) and something later goes wrong - he has the option of saying - "oh, its a warranty matter - call the manufacturer".

Cheers, the plumber does not mind whether i purchase or if he purchases the boiler

The concern i had was whether the logic 30 would be too big for my requirements, as you have assured me i shall not have any issues with cycling/modulation, i shall go ahead and purchase the 30 logic plus and the logic 30 would be fine in future even if we stop using the bath as we will have a shower instead

Although ideally i would want the vogue 😛 looks like a great boiler! but cannot afford to push to a 32, i can afford the 26, and is a relatively new boiler on the market

I'd never offer a 24 if I knew it to be inadequate for the incoming supply, same with a 30! Nobody wants 14l/m of 25 degree water lol. Besides, the price diff between the 2 is pretty minimal.

 

[Jimbob]

No I think more between the difference between the 24 and 35. As 35 usually entails upsizing gas pipework etc.

You will always get cycling with a combi. They are way over kill for most heating systems they are connected too, even the 24kws. On the viessmann you can turn down the max heating output, not sure if the ideals let you

this is what the manual says...

ideal vogue 26

Central heating (CH) output is fully modulating with a range of:
26 3.7 to 18.0kW (12,800 to 61,400 Btu/h)

Instantaneous domestic hot water (DHW) output is also fully
modulating with a maximum of :
26 26kW (88,700 Btu/h)

ideal logic 24 and 30

Central heating (CH) output is fully modulating with a range of:
24 4.8 to 24.2kW (16,500 to 82,600 Btu/h)
30 6.1 to 24.2kW (20,700 to 82,600 Btu/h)

Instantaneous domestic hot water (DHW) output is also fully
modulating with a maximum of :
24 24.2kW (82,600 Btu/h)
30 30.3kW (103,300 Btu/h)

which boiler do you think i should go for?

 

[Jimbob]

Id go for the logic 30 just for the extra flow rate. The vogue modulation is great but not worth the cost of downsizing from 30-26. A decent room stat and properly balanced heating will help prevent cycling to a certain extent

Thank you! the logic 30 it is then! :stooge_curly:

 

[Ermintrude]

If u get logic 30 buy one of their inbuilt remote control timer stats as although I wouldn't normally advocate built in the ldeal ones come with same warranty as boiler!

What he prefers wasn't really the point of my post.

Its what you prefer, and what is in your best interest.

If you buy the boiler, and he fits it, if the worst happens and there are problems, the you have two different contracts.

Non-plumbing people tend to think about a boiler as if it was a stand-alone item, like a fridge or a washing machine, and that it's warranty can be enforced as a stand-alone thing.

However, your boiler is just one component in the larger system that is your heating and hot water. This creates quite a lot of potential uncertainty if there are problems. Is it a boiler problem? Is it a system problem? Is it a combination of the two?

If your plumber has supplied and fitted, you only have one contract, and it becomes his problem. If you supply and he fits, then you have created a whole new grey area that didn't exist before.

I understand your point, I shall discuss this with the installer, cheers

We shall be purchasing the honeywell cm927 thermostat

 

[ash121]

Forgot to mention, Not sure if it is relevant or will cause problems with the boiler..

the kitchen, bathroom and bedrooms have microbore pipework for the CH and the 2 living rooms are 15mm pipework

Will this be an issue for the boiler in any way?

the plan in the future is to upgrade the pipework to 15mm

I would buy two as the first one will be broken in 3 - 5 years!
