What does a hot water heating system include?
A hot-water heating system burns fuel in a boiler to produce thermal energy. The thermal energy is used to heat water, which is pumped through a system of pipes and radiators. The thermal energy is used to heat air, which is forced through a system of ducts and registers. A thermostat controls a home heating system.
Is the hot water tank connected to the furnace?
In an immersed coil installation, the hot water tank contains a heat exchanger that is connected to a furnace, boiler, or heat pump. However, instead of having a heating mechanism inside the tank, it uses the heat from your furnace or boiler. Your furnace or boiler will have a pipe attached to the water heater.
What is a hot water heating system called?
Hot water systems are often called hydronic systems. Residential boilers generally use natural gas or heating oil for fuel. In steam boilers, which are much less common in homes today, the water is boiled and steam carries heat through the house, condensing to water in the radiators as it cools.
What does a furnace circulator do?
The heating system circulator pump, such as the trio of pumps shown at the top of this page, is used to move hot water from the heating boiler out through one or more loops of piping in a building, through heating devices such as radiators, heating baseboards, or convector units, then through return piping back to the …
Will hot water heater work without furnace?
Indirect. Indirect water heaters can be powered by gas, electric, oil, or propane, and operate like direct water heaters. However, instead of having a heating mechanism inside the tank, it uses the heat from your furnace or boiler.
How does a circulator work in a hydronic heating system?
That is, the pump will work in either location and will move water through the heating piping loop (s). That is because in a hydronic heating system the circulator is pushing water around a closed loop: the boiler and boiler piping are filled with water and there is (or should be) no air in the system.
What’s the difference between a furnace and a hot water system?
While furnaces carry heat in warm air, boiler systems distribute the heat in hot water, which gives up heat as it passes through radiators or other devices in rooms throughout the house. The cooler water then returns to the boiler to be reheated. Hot water systems are often called hydronic systems.
How is a circulator used in a radiant heating system?
Heating circulator pumps or “zone circulators” are used to force hot water from the heating boiler through radianting devices such as hot water baseboards or radiators. The circulator is switched on as needed or in some designs may be wired to run continuously.
Where does the circulator pump in a boiler come from?
Hot water boiler systems need a little help pushing the hot water through the piping to heat your home. This help comes from small pumps called circulator pumps that are soldered into the pipes, and thus are part of the piping. Without the help of these pumps, the hot water would never reach your heating outlet.

That is because in a hydronic heating system the circulator is pushing water around a closed loop: the boiler and boiler piping are filled with water and there is (or should be) no air in the system.
What are the different types of hot water heaters?
There are three basic types of hot water heating systems: gravity flow, pumped and baseboard convection systems. A gravity hot water heating system is the oldest and simplest system to heat homes.
Where does a circulator pump go in a water heater?
(Usually leaks go the other way – from the higher pressure water heater water into the lower pressure heating system water).
How does a Hunker home heating system work?
Hunker may earn compensation through affiliate links in this story. Hot water heating systems are built around the premise of radiant heat. Water is heated by a boiler and circulated throughout a building–usually homes (older homes, especially)–through a series of pipes that heat radiators that give off heat.
