Header tank above cylinder

[pauliepie]

Is it right that the higher the cold water storage tank is above

standard vented cylinder the better pressure is available out of th hot water taps???

Is there a minimum height the tank has to be above the cylinder

No. It is the height of the tank above the *tap* that matters.

No; some combination tanks have the cold tank immediately above the hot, in the same assembly.

Also if the tap is a bath mixer with shower say 1.5m long hose,this will reduce your head of pressure at outlet

For good pressure at shower head you need a minium of 1m from bottom of cold tank to the shower head,and preferably balanced pipework.

So if you have a standard airing cupboard with a 36x18 cylinder and a 3

gal cold water storage tank above it and the shower head on the opposit wall in the bathroom mounted the same height as the tank...It is best t move the tank in the loft!!!!

What if there is no room to put a tank in the loft, there will be 1 above the taps but not above the shower head?

I guess its the same for a heating header tank, does this have to be certain height above the top radiator/pipework.

Is there a rule to say that the htg hdr tank has to be higher than th cold water tank or vice versa?

Many thanks guy

Best remove the cylinder and tank and fit a thermal store. Then high pressure hot water all around. Cheap enough from:

look at: (make square stirage vessels) (make heat banks and storage vessels to size) (make thermal stores and stioarge vessels) (make cylindrical heat banks and storage vessels. Will make to order) (make heat banks and storage vessels) (make cylindrical thermal stores and storage vessels. (They are quite cheap and will make to order) make cylindrical thermal stores and storage vessels (make cylindrical thermal stores) _________________________________________ Usenet Zone Free Binaries Usenet Server More than 120,000 groups Unlimited download to open account

low pressure cylinder that has a dedicated shower only coil running though it at the top. The cold mains runs into the coil and is instantly heated giving a high pressure shower. You can fit a blending valve on the hot water draw-off set to 50C and have the stored water at 60, 70, 80C or whatever. A superior alternative to a power shower pump.

They are also available in combination cylinders with the cold water tank and hot water cylinder combined, eliminating tanks in the loft.

That is if you have a loft... The htg hdr tank can be above or below or on a level with the cold storage cistern. However see my SealedCH FAQ below.
