Adding a booster pump to a secondary system

Somethings not right. Bits of info & patently not plumber nor idea so I'm out.

Your problem now is stored hot water

What's the cylinder size

And are you heating via top immersion?

No, heating via boiler. Immersion is on at minute but has just been turned off when taking pics.

I think the butler did it!

What extra info do you want Dave?

I think the point is this doesn’t add up. The cylinder that we’ve seen the top of will not have the capacity to feed three bathrooms I can’t believe this has ever worked

 

[Riley]

Are you a plumber?

 

[SmithO]

Are you a plumber?

No, and have never pretended to be on here. I have a building contract company and have a plumber that is away over Xmas. Needed to see if I can get hot water pressure in short term before putting in an invented system.

Will the cyclinder not work due to the capacity?

 

[SmithO]

Have answered every question that has been asked. Just looking for some advice.

Many thanks.

Should be fine if you run one bathroom at a time but won't last with all 3 going at the same time less than 5 mins on full load

 

[Riley]

My advice would be get G3 qualified engineer in after the festive period as this isn’t fixed just with a pump in fact you are exacerbating the problem and using up hot water even quicker. There’s much more to it

 

[SmithO]

That is the plan inevitably Riley. Just needed to see if can get pressure for bathrooms in the short term. (Showers etc.)

 

[Riley]

I would advise them that there is no quick fix

This is the comment I made earlier. Sometimes the only option is an expensive one. What is the pressure both static and dynamic? you need this info before you know if unvented is viable and recorded at different times of day and especially at times of high usage in the area. You may need an accumulator too. The answer can be quite complex and there are lots of things to take into consideration that may not be obvious to none plumbers. The hot water has been under gravity for years and then you are pressurising it and this can lead to problems not caused by but exposing issues that have been there for ages.

Thanks JV
