New Baxi duotec boiler 28 fitted. Shower less hot and less powerful.

[Barbara]

A new Baxi duotec 28 was fitted in Dec 2017 and the installer has just told me today the old boiler had water heating of 3.1 kW. Is this why my shower is less powerful and less hot since new boiler has been fitted?
I have a 4 bed house with 10 radiators. He recommended Baxi duotec 24 and the only reason I got 28 was because supplier didn't have the 24 on day of fitting.
I feel he perhaps recommended the 24 for ease and speed of fitting.
Any thoughts please?
Thanks

A 28kw boiler may have been installed, as the gas supply may not have been big enough to properly feed a 31kw boiler

Thank you for your reply. He didn't mention that.

28 kw should be ok for a normal shower

You don't have a rain head one do you ?

You will see a improvement as the cold supply temperature of the water coming into your property increases due to warmer weather . Kop

Thank you Kop
If only the installer could have given me a simple reassuring answer like yours. Roll on spring and we'll see. I hope you are right. After he has corrected all his checklist errors I don't want him anywhere near my house again.

Has he check the filters ?

And is the shower hot enough or is it just the pressure?

Would that be filters on boiler or shower.?He has said he can't do anything with shower. He's not interested. I can't honestly say it's bad but just not what I had for many years.. A few degrees make all the difference

They probably should be checked sometime in near future. Confidence in getting right person severely dented at moment so I'll stick with my adequate temp for moment.
When you say turn water temp up do you mean within the workings of the shower?
Thanks Shaun

on the boiler you can adjust the water temp just a thought it may be set low?

any chance you could take a pic of the boiler?

After boiler was first installed I had to get plumber back to increase temp. Couldn't have a hot bath. That he did but flow reduced.
I'm wondering if something as simple as turning stopcock more open if possible might make a difference.

Is that a job for a professional Shaun?

Have turned stop tap on a little more which has improved flow I think.

28kw should be more than good enough the only thing that can effect them is what kop said but as your shower is thermostatic it should compensate
