Indirect cold water:
This type of water system comes through the house through the rising main. Then the water gets separated up to a 24 hour storage cylinder, from here is where the water gets sent back down to all of the appliances that require it apart from the kitchen sink. This is because the kitchen sink is fed water by a direct water source due to it being used for food prep. An advantage of using indirect cold water is if the main supply gets cut off you still have the 24 hour storage cylinder to supply your water until it gets fixed. But a disadvantage is that it is more expensive to install and requires a lot more
Direct cold water:
This type of water system is where the water needed for any appliances is directly fed from the cold water mains straight to the appliances that need it; this is good because they only require small cisterns and a lot less pipework leading from the mains to the appliances and they are a lot cheaper to install, when using a direct water system you only need storages for hot water which means that your cold water comes instantly with ease. A disadvantage of direct cold water is that if the pressure is high there is risk of damage and wear to the pipes …show more content…
The hot water then rises up through the convection currents and then gets replaced by the cold water that comes up from the bottom of the cylinder and that’s how the circulation is made. When required the hot water gets drawn off as and when needed for any domestic uses. Once the hot water is drawn off from the top of the cylinder where the water is at its hottest the cold water fills up again from the water that’s stored in the attic cylinder. In direct hot water systems the water that gets heated and then stored in the cylinder is the water that is used for any appliances which is why, if the system is direct, the water isn’t suitable for the use of central
