But our shower has a venturi meter within it, not sure if this makes any difference, i know it does something with the pressure.


Your cylinder is fed from a big cold water storage Cistern in your case probably in the loft, the result is all the water in the cistern, pushing down into the cylinder, thats where your hot water pressure comes from , thats why the water will run above the cylinder, it will never run higher than the tank in the loft

Nah mattk has answered it via U2U, should really have posted an end to it all in here. My shower is basically a kettle, and it just doesnt have a high enough kWh rating to heat the water at the desired pressure so either need to put up and shut up or buy a new, more powerful unit

she may just have an immersion heater, which is likely if the heating in the house is all electric

you can run a power shower off a combi boiler or a multipoint,

you can only have a boosted shower on systems that have equilibrum ( equal pressures) such as unvented hot water or tank and cylinder systems

do you have a combi boiler? and is the shower an actual power shower or just an electric mains fed shower?

Power showers take a feed from a hot source as well as cold. If the hot supply is no good, then it wont run good pressure on hot. Although, the internal pump should draw it through.
She might need an electric shower which takes a cold source and heats it up if she has no hot water storage.

Ive been to have a look but she doesnt have a conventional boiler (or even a boiler at all :boggle: ) All she has is a tank that heats up water for washing plates and that is set on a timer for an hour every night. She has night storage heaters and fan heaters, no central heating, so there isnt anywhere to check pressure?

Check the pressure settings on your boiler.

I'll need to see pics of your GF in the shower in order to diagnose the problem and provide a solution tbh

My GF has a cubicle shower but the pressure is appalling. If you have cold water its fine but I dont want a cold shower. Turning the water round to anything resembling warm it almost becomes a dribble and it takes 15 minutes to get all the soap off. Anyone know how I can boost pressure to it? Its rented accomodation btw so something that doesnt change the whole system would be good :)
