But, hope it helps.
it usually means the tank is on the same level as your flat rather than the floor above, which would be ideal.
I have this problem but mine is caused by an airlock in the kitchen hot tap, which causes a trickle in the bathroom.
when you get a trickle go to the other hot tap in your flat and turn it on for a few seconds to remove the airlock. (leave other one running) it should then run better if thats the problem
You have two problems here which are interrelated. Firstly your tank will be within the confines of your flat and therefore will not give you alot of 'head' needed to provide a good flow of water. secondly this low head of water combined with hot water will result in occasional air locks occurring. the problem can be solved with a peripheral/regenerative pump being installed on your hot water system. It would need to be a "Negative head"pump if you want to use it to have a shower as the shower head will probably not be 6 inches below the bottom of the tank which is what a stand pump with flow switches requires. Have a look at this pump Vertix PE50 Bronze peripheral pump with Brio on this website: http://www.pumpexpress.co.uk/acatalog/Water_Supply_and_Pressure_Boosting.html
The other thing to look at is whether you have contninental taps as these often need a greater head of water than you currently have. Alot of kitchen taps are rated at 0.5 bar which is the equivalent of raising your coldwater tank 16 feet above the tap!!!
Hope this helps.
