Gravity Hot Water System Diagram

Some systems also feed cold water to bathroom cold taps and the toilet cistern so the only mains water is going to the cold tap in the kitchen.

Gravity hot water system diagram.

Water may be too hot. As the water cools at the end of the loop where the last part of the loop is not insulated it is thermo siphoned back into the hot water heater dear tim. Hot water takes a long time to replenish. I am not a big fan of cold showers.

This is a diagram of the obsolete one pipe pumped system. Gravity hot water recirculating system a gravity hot water system works because the heated water which is lighter rises through the loop. One of the most basic ways to build a running water system is the gravity fed system. Hot water systems on the other hand were open to the atmosphere and relatively safe because the old timers usually limited them to a high temperature of 180 degrees f.

This allows gravity to do all the work of moving the water through the system eliminating the need for a water pump whether mechanical or electric. In those days you could liken the difference between a gravity how water system and a steam system to that of an open simmering pot of water and a pressure cooker gone berserk. The hot water taps will be fed from the tank in the loft which flows by gravity down to the hot water cylinder and forces hot water out to the hot water taps. A gravity system is easily identified there will be four pipes connected to the boiler.

A guide to the different ways of heating domestic hot water so you can identify problems and faults with the hot water tank or central heating system and carry out any maintenance needed. Old unmodified gravity systems are usually direct which means the water from the hot taps and hot water cylinder is the same water that is circulating through the radiators. It consists of a cistern or holding tank at a higher elevation than the point of use. Frequent boiler firing as water thermocycles.

Tuscan boilers by hounsfield can be used in gravity hot water systems.
