Gravity Hot Water Heating System

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.

Gravity hot water heating system. In a hot water gravity heating system the circulation of water is a result of the density difference between hot water in the supply lines and cold water in the return lines. The elevation of the supply and return lines are therefore important for proper functionality. In fact gravity hot water heat is the mirror image of forced hot water heat. It is also the least efficient.

Gravity hot water heating began quietly in the united states between 1875 and 1885. Hot water heating systems need a little maintenance like venting the radiators and draining the boiler to keep things running efficiently. In gravity hot water systems heating of domestic hot water relies on convective action to circulate hot water from the boiler to the cylinder. In a gravity system the circulation of water is due primarily to thermal and density differences between hot and cold water.

A gravity hot water heating system is the oldest and simplest system to heat homes. Hot water takes a long time to replenish. When you use a circulator in any system the path of least resistance will always be the shortest lowest pressure drop loop because that s the path with the least resistance to flow. When you use a circulator in any system the path of least resistance will always be the shortest lowest pressure drop loop because that s the path with the least resistance to flow.

Gravity hot water recirculating system a gravity hot water system works because the heated water which is lighter rises through the loop. I am not a big fan of cold showers. I have to. The hot water tends to flow upwards and cold water tends to flow downwards.

A gravity system takes longer to heat a home because it lacks a fan to force the warm air into the rooms. Gravity circulating heating system. It was a canadian import a safe substitute for steam heat which had been earning a notorious reputation throughout the world as being a pretty dangerous way to heat a building. An efficient modern forced hot air system uses 95 percent of the heated air to warm a home notes the national association of certified home inspectors.

In fact gravity hot water heat is the mirror image of forced hot water heat.
