As this is a high rise building there is a lot of  gravity which means the water flow will be better throughout the building.

While less useful in smaller residential locations in a large area such as an office block or somewhere else there greater capacity means that there is going to be a directly proportional relation into  that of use which means that there is going to be higher use. Because of this it is going to be essential that more hot water is delivered which can be achieved by the indirect system due to inverse square law of gravity allowing for a greater distribution.

The second advantage is that the indirect system is able to hold a certain capacity of water. In time when an emergency has occurred, having a certain capacity of water can be useful as it may be time before the system can be repaired allowing for a limited amount of time of people still being able to reside within the area. Also it means should there be a fault in the direct supply, the remaining capacity can still be used until it has ran out.]]> 2020-10-23 08:53:50 UTC https://padlet.com/kieran_barry/ps9u1k687e7p/wish/855261509 https://padlet.com/kieran_barry/ps9u1k687e7p/wish/855262626 you can cut of the water from certain areas insted of shutting the whole thing down ]]> 2020-10-23 08:54:51 UTC https://padlet.com/kieran_barry/ps9u1k687e7p/wish/855262626 https://padlet.com/kieran_barry/ps9u1k687e7p/wish/855262883 if the mains is damaged then you still have a water tank for back-up

Added to this the chance of the structure being flooded if there is a fault with the water storage tank  which can lead to a  massive cost in order to repair it.  Added to this is that the size of the house means that more money has to be spent simply accruing such a structure that is even capable of holding the indirect system in the first place. 

The other disadvantage is that there is a serious risk of contamination and risk to health as water has a high risk of being unsatisfactory for human use, due to animals which will use such water for their use which will lead to not only contamination. There is also the risk of building materials falling in the water storage tank such as insulation but especially the risk of Asbestos if the house is of an older make which is more likely due to the fact that 70% of UK households have a direct system  which means in correlation due to the time it was introduced that the older a house is, the more likely it is to have asbestos within it's construction which is also more likely to coincide with a building having an indirect system]]> 2020-10-23 09:02:57 UTC https://padlet.com/kieran_barry/ps9u1k687e7p/wish/855271203 https://padlet.com/kieran_barry/ps9u1k687e7p/wish/855271249 2020-10-23 09:03:00 UTC https://padlet.com/kieran_barry/ps9u1k687e7p/wish/855271249 https://padlet.com/kieran_barry/ps9u1k687e7p/wish/855271341 Some cons are:

This is because they rely on gravity. They also need to have space to store the water tank at the top of the building. Therefore it wouldn't be used in a building such as a bungalow.
You would use a direct water system where the mains pressure of 1.7 bar is enough, for example a bungalow where there is only one floor so there wouldn't be enough height for the gravity. You would also use a direct system where space is limited, as there is not enough space to store the water tank and cylinder.

Tank can be left exposed to rats and bats, for example, if lid has been left off.

Pro and Con:
Uses gravity which is good as no pressure is needed, but is bad if you have a small building such as a bungalow as there is no height for the gravity.]]> 2020-10-23 13:26:18 UTC https://padlet.com/kieran_barry/ps9u1k687e7p/wish/855708977 https://padlet.com/kieran_barry/ps9u1k687e7p/wish/855709952 pros:
- if a leak happens then you could shut it all of easily 
- even if the water supply to the property is cut off, there's still a reserve of water.
cons:
- water pressure is weak 
- useless in small buildings ]]> 2020-10-23 13:26:33 UTC https://padlet.com/kieran_barry/ps9u1k687e7p/wish/855709952 https://padlet.com/kieran_barry/ps9u1k687e7p/wish/855720172 There is an Increased chance of water contamination due to the storage of water]]> 2020-10-23 13:28:58 UTC https://padlet.com/kieran_barry/ps9u1k687e7p/wish/855720172 https://padlet.com/kieran_barry/ps9u1k687e7p/wish/855735422 Con:

If your pipes are not secured properly the crash of the water stopping in the pipes and shake and loosen them ]]> 2020-10-23 17:01:28 UTC https://padlet.com/kieran_barry/ps9u1k687e7p/wish/856590281 https://padlet.com/kieran_barry/ps9u1k687e7p/wish/957084416 2020-11-24 17:15:21 UTC https://padlet.com/kieran_barry/ps9u1k687e7p/wish/957084416 https://padlet.com/kieran_barry/ps9u1k687e7p/wish/971596084 2020-11-30 15:08:31 UTC https://padlet.com/kieran_barry/ps9u1k687e7p/wish/971596084
