Hi all

A colleague of mine has bought a property to do up and sell on.
It is a 3 bed terraced place with no ch.

He has been quoted a seriously cheap price £804 to fit ch. I think
this was for an 18kw noname boiler.

Indeed it does seem rather too cheap...

As this is just for flipping, it is likely the question is
immaterial, but I was wondering what is the minimum boiler rating
that is likely to be able to provide decent flow for a
shower?

I'm thinking this place would only have space for a single
bath/shower room.

The short answer is a qualified "yes".

Flow rates against power are shown in the table he

With 18kW (if you assume that is the output power to the water), you
would be limited to around 7.3 lpm in the depths of winter, and perhaps
10.3 lpm in the summer. Probably acceptable by most people's standards,
especially as it will be at a decent pressure. Certainly better than the
most powerful electric shower.

A 24kW combi is perhaps a better minimum spec - especially if there is a
bath. However if he is just selling it on, then all that really matters
one might argue is that it "works".
