Cylinder Performance

[steve26]

Can anyone tell me how 'constant flow' works on an indirect unvented hot water cylinder. Many manufacturers have litres per hour figures in their literature and then reheat times in the same table.

This means it can produce so many litres per hour based on a certain boiler input does it?

If you start with the cylinder hot and heat it with a 24 kW boiler for example it will reach an equilibrium whereby you can continue to draw off about 7 litres of water per minute at 55°.

The actual flow rate will depend on a number of factors.
