Boiler advise for loft conversion please

[Neddyis200]

Hi everyone a newbie ere. I'm looking at doing a loft conversion so I want to get rid of my hot water cylinder and cold storage tanks in the loft. I also want to put in a new boiler as the current one is old.

I plan on fitting a shower in the loft as well as have my current shower and bath on the ground floor. It's currently a three bedroom house. Will a combi work two showers? Will I have to put an electric shower in the loft? Current have 15mm pipe feeding cold storage tanks. Static pressure is 2.8bar . Running pressure 1.4bar with a flow rate of around 21 litres a minute.

Any advice would be appreciated .

If you are having two showers and a combi, how about having one as an electric shower. Not ideal, but nice to have a back up in the event of a boiler issue.

Agree with simon, 1 x electric shower and one off a combi would be best compromise.

Brilliant advice Simon, I always recommend this to customers aswell!

In all honesty a combi is unlikely to provide two showers with satisfactory flow rate's at the same time

Thanks for the replies. What kind of flow rate should I get from An electric shower? Also noticed my boiler has a 15mm gas feed. Do all new boilers need 22mm? I have 22mm coming into the house but no idea where it goes!

You need a gsr to advise on that.
