When sizing an unvented cylinder firstly determine the type ie direct or indirect. As an average a 3 bed house with 2 baths/showers allow 180 - 210 litre a 4 bed house with 2 baths/showers allow 210 - 250 litre Any thing larger 300 litre + BoilerOne recommend you consult a heating engineer with an unvented qualification to install your cylinder.

When selecting the size of your hot water cylinder there is a simple rule of thumb it is for a typical domestic household, you should allow between 35 and 45 liters for every occupant. that said a mains pressure system can use about 18 liters of water per minute at 40 degrees Celsius if a decent quality shower head is used.
