High flow Combi experiences!

[Fireboy24]

Hi All,
have got a customer with a 5 bed house (two bathrooms and a shower). They want to replace and open vented Y plan system and ideally want to lose the cylinder as they're very tight for space believe it or not.
Thinking of quoting to put a Worcester highflow combi in and a booster tank on the mains (tws) to give them great pressure and flow coming in. Any fitted the Worcester high flows before?? Do they really handle 2 bathrooms (remember I'll have good mains) with ease as they claim??

thanks

nope keep the cylinder as they have more than one bathroom/shower

Even though the combi gives you 20 litres a minute DHW?

5 bed house with 2 bathrooms + shower room If i had good mains pressure/flow I would want to fit a pressurized cylinder. if I was tight on space I would look into fitting a horizontal 1 in loft.

Just explain that a Highflow is a compromise compared to a cylinder, but if used sensibly (ie not expecting to run 2 baths and a shower at once) then it won,t be much of a problem
Should comfortably run a pair of standard flow rate showers, but also depends on number of people in house
I wouldn't lose a job over it

Not constant though! Will drop off after 5 mins.
Like above point out the pitfalls and benifits of the storage combi, but don't make claims higher than can be produced.

Fit what customer wants from experience they will only use google

I have fitted a high flow 550 in a 2 bathroom property. Both bathrooms had 10-12 inch shower heads and you could easily run both at the same time. I wasn't expecting it to be as good as it was, the only reason I fitted it was a lack of space. I would now happily fit one again.

Floor standing Worcester highflow or vaillant storage combi both offer unvented cylinder performance if the mains is adequate!

I always say I recommend a cylinder but will happily fit you a combi. What's the point in losing a job because you won't do what a customer wants.

Because normally if there not going to listen to you they will pick the cheapest price, or there going to blame you when it doesn't work

My opinion not worth the bother
