Combi with highest DHW flow rate?

[Masood]

What's the highest DHW flow rate combi that you know of? I have 25l/min mains and I want to take advantage of that.


Was thinking of going unvented but not really worth it in my flat..

 

[lame plumber]

intergas are rather good, fm experience the output is better than they advertise

 

[stevetheplumber]

i think intergas as well

 

[Masood]

Well, I'm a big Intergas fan already but even the 36/40 has an advertised flow rate of 13l/min @ 35 delta...

I really want to install a Eco RF 36, but 13l/min seems a bit low..

just remember the 36 is the combi max the 40 is the heating max, never got my head around that particular model. your flat won't be needing a 40kw input to warm a few rads!!!!!!!!!!!!!!!!!!!!

Wall hung or floor standing?

Ha! That's the opposite to the others, the higher rate is DHW on all the other HREs. No, definitely don't need 40KW for CH LOL. Was thinking 40KW for water and rate the CH side right down..

nope first figure is hw and second heating, same as the rest.

 

[stevetheplumber]

rapid 32 gives 15l at 40 degrees acording to the paper work ive got

Yes, and the first figure is higher on all except this one. Should have put 2 and 2 together, durr!

So 36/30 is my best bet. Can set CH power down to 25% from memory, so about 7KW for CH side. Haven't done the heat loss calcs yet but should be about right...

At least they have engineers to cover warranty

 

[stussy]

You get 17.2 litres a min at 35deg on a worcester 42cdi combi. Or more on their highflows

 

[dazsl]

vaillant 938 does 15.3

Don't forget the water meter £££

 

[thompsonbrown]

Worcester do the green star combi with 22pm might be a bit big if you only getting 25 at the mains.

Highflow 440

 

[mfgs]

The Worcester Highflow does give amazing hot water performance. I have only fitted one, the 550, but you could run a bath and have a shower at the same time comfortably.

GW energy 35 store combi 21 l/m twin tank
I was going to instal one for someone last year but it never happened due to price they went for Logic + instead.
Seemed quite good from what I remember bit bulky though, it was going to go in the garage.
I've fitted Atag A325EC in my house in loft space (chalet bungalow) you probably wouldn't want that in your kitchen as also big, water flow nothing special think about 13L but very economical due to built in pre heat been in approx year now so far no probs.

Glow worm ultra com 35 store nearly 20 lpm

 

[harrygashull]

Go for a highflow... and then get a crane to lift it into your loft haha
