New boiler - electric shower question

[Chuckles1066]

We're about to replace our ten year old Vaillant EcoTech Pro 28 boiler with a Worcester Bosch 32CDI.

Sorry Vaillant, you aren't fit to lick the boots of our old 40 year old Baxi Bermuda back boiler (which didn't miss a beat and we only replaced because we were told modern boilers are so much more efficient). Yeah, I've got a bridge to sell any of you who bought into that rubbish.

At least the Worcester Bosch comes with a ten year warranty so I can suckle on their golden teat until 2034.......

The guy who quoted us said if we had the 32CDI as opposed to the 28CDI then we could have a power shower installed when our electric shower finally dies (due to the increase flow rate?).

The shower runs directly off of the mains supply so surely the boiler size/power is irrelevant?

I don't think you can have a power shower installed with a combi boiler (if this is what you have?). You could just have a mixer shower that fed from the mains hot and cold.

You're fitting a WB for a Vaillant and think that the WB is going to do a better job, lol good luck with that

If you have a Hot Water cylinder then you can install a power shower, if not and it's a combi going in then you'll have mains hot water and a power shower would not be an option, if the mains water supply is good enough of course.

It depends on what one's definition of a power shower is. I thought a flowrate of anything over say 10LPM is considered a power shower. If so then a 28kw combi boiler will give a flowrate of 13.38LPM to give a showering temp of 40C from mains at 10C, a 32kw will give 15.29 for the same conditions, both power showers?.
A 10kw electric shower will give a flowrate of 4.78LPM for the same conditions so the boiler size/power is very relevant regarding the mains ability to supply those flowrates.

10 years is nowt when it comes to the life of a boiler. Does it really need replacing?

I define a power shower as one fed from separate, gravity fed H&C supplies, the unit contains its own pump which provides the desired flow.

 

[Johntheo5]

Thats fine then. So why do you require a 28/32kw boiler?, are the CH requirements dictating it?

+1 - I've always known a power shower to be something that looks like an electric shower and, as suggested, is gravity fed and has an integral pump. Can't be used with a mains supply.
