Hi All,
New here so just like to say Hi.
I have three mixer showers in a property that need some more pressure. The property has an Ideal Classic SE21FF Boiler hooked up to a A/S OSO indirect 20 RI Unvented cylinder (Holds 210Litres). The cold water is supplied on the mains to the showers. My questions are as follows:
1) Can I put shower pumps on the hot water pipe to the showers to increase the pressure?
2) Can I put a pump on the cold water main to increase the pressure?
3) Will the Cylinder be able to cope with the demand?
4) Will the boiler be able to cope with the demand?
5) If yes to all the above can anyone suggest a good pump for this installation?
Thank you in advance for any responses.
Andrew  |

1, No

4, should be ok.

Will post more when I get back from snooker, but you need a break tank.

Hi getafix 1163 
Can you give me a tad more info on the system.
The Classic se21 is 20kw boiler so how well it copes is down to the size of the system etc.
You cannot pump the mains or from an un-vented cylinder, however what you can do, I assume you are having problems with the mains pressure/flow, is install a break tank and pump set, then pump the feed into the cylinder using the existing PRV, stopcock combination valve.
You can then take a balanced cold from the same valve.
