Combi vs Standard Boiler

I recently had a combi installed and put in a mixer shower. I can tell you that compared to an instantaneous electric shower its a million times better! However if you have a pumped shower at the moment I think you'll be a bit dissapointed.

The average pump is approx 1 bar. If your mains pressure is above 1 bar then you get a better shower with a combi.

OK, thanks everyone. I think I will stick with installing a pump and hope that I don't keep running out of hot water. I am not bothered about the bath filling duration. It's the showering experience that is important. The risk of interrupted flow when another tap is run I think is too great and it does seem to be a real problem for a combi.

Get a high flowrate combi and if the main is fine then it will perform very well. Have a dedicated 2mm pipe for the cold cold inlet from the mains stoptap and a full bore stoptap. then all will be fine.
