We live in a bungalow. It looks like the heating system has been completely replaced within the last 5-6 years. Since we have lived in the house. (2 years) we have had a problem with the hot water pressure which trickles out of our taps and needs regular bleeding every couple of weeks. Even after bleeding the pressue is still poor. The Boiler is situated in the attic and the immersion heater is located in a downstairs cupboard. We have been advised that it may be due to the location of the immersion tank being on the ground floor that it cannot cope with pushing the hot water throught the pipes up into the roof then down again into the taps. Is this likely??
So do we get the immersion tank resited or is it possible to fit some kind of pump to cure the problem??
If you increase the height of the feed and expansion tank, the water pressure should increase. If it is just a trickle though, could it be down to a faulty valve or blockage in pipework. Is it a pressure problem or flow rate problem ?

Hi. Cheers for replying.
The water pressure and flow rate are poor. Spoke to someone yesterday and they thought it might be 'furring' in the pipework!!!
Where should we start to try and narow down the possible causes?
Hopefully your f&e tank is higher than your hot water (immersion) tank, but by how much? It's unlikely that your pipework is 'furred' up enough to stop the hot water so much but it could be some other sort of restriction from scaling in the pipe breaking off in larger pieces (this is also unlikely)

Hi sorry for the late reply, I have only just seen this.
The immersion tank is on the ground floor level and the water tank is about 1 half metres above in the roof.
This problem is becoming very annoying now as you can imagine!
As Htg says, the solution to your problem is to raise the height of the F&E tank as high as possible in the loft. Fitting a pump in the airing cupboard next to the cylinder may just draw more air into the system.
What is happening is, because the tank is so low, air is being drawn down the expansion pipe into the pipework when you turn on a tap. This air gets trapped and stops the flow.
