It actually depends on what country you live in and the building codes there. However, most countries allow the flue to go through a wall which is an outside wall (it cannot pass through other rooms to get out). It also requires thatt the boiler manufacture allows for this
The place where water is stored for a house is typically called a water tank or water storage tank.
James Bothwell Water Tank House was created in 1926.
Water flows down from a height. If the water tank was not higher than your house, the water from the tank would not flow to your house without the use of a pump.
The septic tank is full and needs to be pumped out.
Yes, if your house has a septic tank water from the sink and bath will eventually goes to the septic tank. However if your house is equipped with a fully dual grey water/black water sewage system, water from the sink and bath will first go to the grey water storage tank, the toilet will fill its tank from the grey water storage tank then flush through the black water pipes to the septic tank.
If you don't have sewer service to your house, it probably goes into a septic tank, but we have no way of knowing what whichever yahoo built your house did. It might run right back into the water tank for all we know.
There is no filter in a hot water tank. It is very easy and cheap to fit one either side of it.
Because water flows downwards, and by help of which we can get a evenly distributed water supply in the house.
The supply line is blocked, tank is too high, etc
If you are coming from a city or county water main you do not need a water tank or pump system as the main should already be pressurized.
Yes, you will only have as much pressure as you do with the cold side, probably slightly less.
Install on cold water line.
