How to Determine the size of my Hot water cylinder tank in house

Hi All

Im looking to replace my Hot water Cylinder tank in house.

(House is a standard bungulow 3 bedroom house)

Reason being, i believe, the internal heating element inside the tank is leaking and water is settling back into my Expansion tank.

For background as my knowledge on heating systems is pretty basic - I have a water tank in loft and this feeds into hot tank. My hot tank is connected to my boiler system (So i think its called an indirect Cylinder like below?)

However, in order to check out prices of tanks, Im trying to determine the size of my tank in litres?

I can find no markings on the tank and am unable to see the back of the tank due to how its mounted in cubard.

Can anyone tell me how to determine the size of my tank so I dont go out and have the wrong one delivered.

Ive tried using calculation for volume in a cylinder => Vol=H(Height)r(Radius)^2(pie) but value i get back seems too big.

Anyother way to figure it out tank size?

Thanks in advance.

Measure the height in inches together with the width of the base.

38 x 18 would be a common size - 120 litres

These figures make allowances for the curve on top and bottom so don't "math out"

Vol=H(Height)r(Radius)^2(pie)

Say you tank is 400 wide and 1000 high, ignoring curves and insulation

so 1m*0.2m*0.2m*3.14=0.125 m3 or 125 litres
