Suggest gas combi boiler

[Depo]

You need the the Ferroli Lamborghini boiler... If there no longer making that you need a Ravenheat...

Lambo not being made any more. Just checked Ferroli top boiler - Modena HE. Not impressed. 27kw uses 100w when burning. No w specified when idle. Also just 11.1L/min@35 isnt anything impressive. Noise level not specified at all. Doesn`t mention if heat exchanger is stainless steel or aluminum.

Ravenheat uses aluminum heat exchanger, not option for me, I only want best 🙂 Worcester also uses aluminum only, every model.

ecotec plus and pro use the same internal components plastic to metal wise.

Vaillant tech rep told me this over the phone - Pro is cheaper because it uses more plastic parts rather than brass/copper.

The boiler you want doesn't exist, you'll have to compromise.

I want a car that seats 7, gives 90 mpg, does 0-60 in 4 secs, has 4WD, 25,000 mile service intervals, costs under £8k and offers a 7 yr unlimited mileage warranty.

All of those features are available. You just can't have them all in the same car.

My personal view is that you are misunderstanding the various claimed features of boilers. BOILERS don't have set efficiencies, except on a test rig. Its the INSTALLED SYSTEM that has an efficiency, and that depends on design, installation, commissioning, controls (both in terms of capability, but more importants user understanding) as well as a host of other issues - apart from the system.

If you will forgive me for saying so, this is a classic case of a little bit of knowledge being a dangerous thing.

You want this stainless steel heat exchanger too

You want this View attachment 22059 stainless steel heat exchanger too

Do they do them in Red??

If you feel very rich, then you can always buy Worcester with aluminum which will corode in few years time. I prefer to make smart purchase to avoid such issues.

you wont have more than 10 - 12 years out of your boiler these days (combi) realistically

 

[Depo]

You can predict future?

Still - why would you buy inferior boiler if you have choice of other better ones?

nope just going on current models and there not inferior main brand boilers

 

[Depo]

Worcester has aluminum heat exchanger, consumes more electricity, noisier. You don`t call it inferior?

They are hugely popular because installers can make more money on them +they invest ton of money in marketing. It doesn`t make boiler itselft any better.

 

[Dotty]

Why are you arguing the toss with guys who fit and work on these things day in, day out?

 

[Depo]

This is not an argument, but discussion - whole idea of such forum. Facts are facts, I have compared boiler specs.

And why installers fit Worcester? Because parts are widely available, better profit margins compared to other makes, better tech support maybe. But again - it doesn`t actually mean its best boiler out there. I can understand its not easy to accept this fact, because you might be fitting 10 Worcesters a week.

😀 there not nosier,alu conducts heat better and doesnt matter if alu or ss both do the same and work in the same principle, and i bet if you ran each make of main man boiler you wont find much difference in elec cost

i can get parts for any boiler within a couple of days so that doesnt come into context to that, viessmann commercial i have found have the best tech support so far, and not greater profit margins as there getting other quotes from people installer other boilers eg ferroli, Vokera, and Aristons just to name a few

Just going to bat this away sharply Worcester have an awful profit margin for the installer.

I haven't read the whole thread nor do I intend to but personally Worcester are far from the best boiler out there.

But within few years you will have to replace it.

How 45 against 38 dB is not noisier? You might think some 25w is not a big deal. But how much in terms of money is that let`s say over 5 year period? A lot.

HE +extra consumption = not the best deal. If Worcester would cost something like 20% less compared to others - yes it would make sense, but it doesn`t.

 

[IDCHAPPY]

Worcester and profit in the same sentence is non compatible. Have you checked the price of them?

how do you know them figures are right/ same conditions unless there in the same room test is invalid

 

[Depo]

Yes I have checked everything - specs and prices. They all cost pretty much the same, but specs do vary.

have a look at ideal logic then and you will see what i mean

Hamworthy Modumax. That's my boiler of the moment.

Good luck!

I'll be watching this thread with interest.

big house? and have you check ip addy its not a modd winding us up??????

Fit a 32kw Vogue FFS 😀

 

[wattsie1987]

No.



I`ve read quite opposite. Because UFH requires much lower water temp, boiler works in condensing mode, which is very efficient.

You've missed the point there UFH works on consistent constant heat not cutting out every time a hot tap is touched.

 

[wattsie1987]

Vaillant tech rep told me this over the phone - Pro is cheaper because it uses more plastic parts rather than brass/copper.

Nothing to do with the size of heat exchanger built in filling loop, user interface or the aesthetics then? I've only been fitting 3 a week for the last 5 years so what would I know !

 

[Depo]

have a look at ideal logic then and you will see what i mean

Ideal VOGUE COMBI(their top of the range)

Up to 1:7 modulation(but Baxi Platinum Combi has a massive 1:10 modulation ratio)
Stainless steel HE
89.1%
10.6L/min@35

So far decent spec. But I cannot see dB level +power consumption when idle/burning at max on their spec sheet. Therefore cannot be compared to other boilers.

That is not domestic, unless you need that 100kw boiler for your zillion bedroom mansion.

I could not find either, so emailed Worcester. Their reply:

....our models are rated at 50-55 dB
