Why when installing a Hot Water Cylinder would you ensure the plywood board the HWC is mounted on has a hole in the centre?
To ensure expansion of the plywood
To stop the plywood from warping
To ensure any condensation on the underside of the cylinder can escape
To enable inspection of the underside of the cylinder with an inspection camera
Answer explanation
It is important that condensation is not allowed to build up on the underside of the HWC. If it does it will drip onto the wooden base and overtime will rot the base and lead to catastrophic failure of the wooden base. That is the reason a hole must be made before the cylinder is placed on it.

Why is it imperative to ensure the F&E Cylinder is positioned lower than the Cold Water Storage Cistern?
To ensure there is not one pipe circulation
To ensure contaminated water cannot pass from Primary to Secondary
To ensure the F&E cylinder never vents into the cistern
To ensure the CWSC is bigger than the F&E
Answer explanation
In the event of pinholes forming in the Coil. If the F&E was installed above the CWSC there would be greater pressure in the F&E. So 'Dirty' water from the Primary Circuit would force its was into the Secondary Circuit.
By ensuring the pressure is greater in the CWSC the opposite happen so you are less likely to contaminate if pinholes are on the coil.
