no hot water in ensuite

[apcdave]

Hi chaps,

How easy is it to fit a booster pump to a hot water supply? No flow from hot tap in en suite - situated some distance from the hot water cylinder. The cylinder is supplied by a cold water storage tank in the loft but the hot flow then goes back up into the loft and has to travel full length of bungalow to reach the en suite. Where would a pump need to be situated?

cheers fellas

In hot press and unless that en suite is piped separeted from the rest it will have to be a hole house pump

People just don't seem to have any basic knowledge of how to fit pipework anymore. They seem to think everything should work as mains pressure.
The pipe needs graded properly. It won't work as it is. Get a decent plumber.

You are getting airlocks in the loft as air settles at the highest point. You could push the air out by putting mains pressure up the tal and it would push the air up into the vent. I have found that this is only a temporary fix and the best way is to go back to basics and put the pipework under the floor to the en suite and the air will vent itself out in the normal way. Alternatively get an unvented cylinder installed.

The cwsc is the main factor here this is called the head and this is what is forcing water to your hot water outlets, you should not need a pump, the pipework run to the en-suite is poor it should not ideally go back up into the loft, sounds like you have a long horizontal run as well, but it should still work, size of tank matters to, and it needs to be raised up in loft, higher the better, pumps are last resort they are noisy, it should not need one.

Another option is to cap off existing hot pipe in loft to en-suite, go into loft and put a tee into expansion of cylinder and run a pipe in loft slowly falling all the way towards new en-suite, and pick up the hot pipe were you have dropped into the en-suite, it should work a treat.
