The boiler process
- Your home’s thermostat senses a drop in your home’s temperature and calls for the boiler to turn on.
- Your boiler powers on and uses either oil, gas or electricity to create heat.
- The heat from the fuel source is used to heat up water inside the boiler.
How does a residential boiler actually work?
Jul 22, 2019 · The boilers work through heating the water. They can produce steam as well, which can help to heat the house. You may use the boiler when there is a change in the home’s temperature. The thermostat present at your house can easily sense a difference in the temperature so you can use the boiler in that case.
How efficient is your boiler?
Boilers use hot water or steam to warm your house. The water or steam travels through pipes or radiators and warms the objects in your home. Furnaces blow hot air through a duct system, which warms the air in your home.
How does a boiler work step by step explanation?
How does a residential boiler system work? The boileris the most important part of a central heating system. A valve opens, gas enters a sealed combustion chamber in the boilerthrough lots of small jets, and an electric ignition systemsets them alight. The gas jets play onto a heat exchanger connected to a pipe carrying cold water.
How do you install a boiler?
Your boiler powers on and uses either oil, gas or electricity to create heat. The heat from the fuel source is used to heat up water inside the boiler. The heated water or steam is sent throughout your home (via radiators or radiant floor systems) where it gives off its heat to warm the air.

How does a boiler work?
But the primary purpose of all boilers is to transfer heat to water. Basically, boilers work by heating water or producing steam that is then used to heat a home. But, of course, that’s a barebones explanation of how boilers work. The inner workings of a boiler gets more complicated ...
How does water travel back to the boiler?
As the water cools (or the steam condenses), it travels back to your boiler where it’s reheated and sent back out to continue heating your home. This process continues until your home reaches the set temperature and your thermostat calls for the boiler to turn off.
How does water get sent to the boiler?
As the water cools (or the steam condenses), it travels back to your boiler where it’s reheated and sent back out to continue heating your home.
What is a gas boiler?
Gas boilers. When it receives the call for heat from your thermostat, a gas boiler uses either a pilot light or an electric start to ignite gas and oxygen inside a “combustion chamber”. The combustion chamber is a safe, secured chamber where the gas is burned to produce heat.
What is the combustion chamber?
The combustion chamber is a safe, secured chamber where the gas is burned to produce heat. That burning gas heats up the “heat exchanger”—a web of copper piping that transfers its heat to water. Gas boilers are the most common form of boilers and are usually cheaper to install and operate than oil boilers.
What is the difference between oil and gas boilers?
However, the main difference between oil and gas boilers is that an oil boiler requires an oil storage tank. The oil must be delivered to the home and stored in the tank until it’s needed. Oil boilers aren’t as eco-friendly as gas burners but they can sometimes be more efficient, depending on the model.
Is oil boiler more efficient than gas?
While oil and gas prices fluctuate, oil boilers are generally more expensive to operate than gas boilers.
How does a boiler work?
In a steam heating system, the boiler heats the water until it becomes steam. The steam then travels through the radiators to transfer heat before condensing back into water and returning to the boiler for reuse. (Pictured above: A residential radiator) Another common boiler terminal is a baseboard register.
What happens if a boiler is exposed to water?
Water Damage. Water damage can be disastrous to a boiler; it’s therefore critical that a full evaluation is performed when a boiler is exposed to water for any period of time. Following a water loss, the boiler’s electrical components, the burner, and even the combustion or heat chamber can have a myriad of damages.
What type of fuel is used in a boiler?
Two main types of fuel are used in residential boilers: natural gas and oil. Natural gas burns cleanly and has been cheaper than oil in recent years. Gas is supplied from the utility company through service lines into the home. To identify if a boiler is using natural gas, look for a gas supply line with a shut-off valve near the boiler.
How to tell if a boiler is using natural gas?
To identify if a boiler is using natural gas, look for a gas supply line with a shut-off valve near the boiler. (Pictured: A residential gas boiler) Oil boilers, on the other hand, require a large on-site tank that stores anywhere from 200 to 1,000 gallons. Oil is often used in areas where natural gas is not available.
Is oil used in a boiler?
Oil is often used in areas where natural gas is not available. Additionally, the initial pricing for a standard oil boiler often costs two to three times more than its gas counterpart. Delivering Heat Through Different Types of Terminals.
Can a boiler burst in winter?
During the winter months, freezing temperatures can burst pipes and valves on all types of boilers. This can occur in a single zone or throughout a home’s system, and the resulting water damage can be catastrophic if it’s not handled quickly. Additionally, the scope of damage may vary significantly.
What happens when a boiler doesn't ignite?
When it does eventually ignite, the excess fuel can cause anything from a small amount of smoke to a minor explosion, which is then released into the area surrounding the boiler.
How does a boiler work?
While there are several different types of boiler available for residential homes, the way they work is similar. A boiler has a heating component — either gas flame or oil — that creates the heat. Water pipes run through the boiler and a heat exchanger. The heat exchanger component allows the heat source to warm up the water without direct contact.
What is the heating component of a boiler?
A boiler has a heating component — either gas flame or oil — that creates the heat. Water pipes run through the boiler and a heat exchanger. The heat exchanger component allows the heat source to warm up the water without direct contact. Circulator pumps then push water from the boiler into the central heating system, to a water storage tank, ...
Is oil efficient in a boiler?
Newer oil-fired boilers are incredibly energy efficient and can heat water on-demand. As you buy the fuel by the tank, you’re also able to budget more easily and have the freedom to switch residential oil supplier whenever you want.
Is a back boiler reliable?
However, back boilers are known to be very reliable which is why they’re still going strong decades after they’ve been installed. They’re not as efficient as modern conventional or combi boilers. If yours needs replacing, it’s likely you’ll need to upgrade to a combi boiler to comply with building regulations.
How does gravity work in a boiler?
The gravity action draws water down and it then enters the pipes in your central heating system. As water expands when it’s heated, the excess will flow back into the upper storage tank. Conventional boilers are excellent for large families as you can run a shower and several hot taps at the same time.
Can a boiler run a shower?
Conventional boilers are excellent for large families as you can run a shower and several hot taps at the same time. They’re also very efficient — but do require a lot of space for the water tank (as well as an attic for the gravity-fed system).
What is a gas boiler?
A gas-fired combination — or combi — boiler heats both your central heating system and your hot water from one unit. It saves you space, is incredibly efficient, and will be reliable and cheap to run.
How do apartment building boilers work?
Before we move on, let’s see what is a boiler. Simply put, a boiler is a contained vessel where water is heated or boiled and then transported via ducts as hot water or steam to heat up spaces.
How much does a boiler cost for an apartment?
A standard boiler costs $3,500 on average for a large home or apartment. Installation or labor charges bring the cost around $5,000.
How to install a boiler heating system?
The location you choose to put your boiler should be at a safe distance from windows, rain, hail or direct sunlight. You should ideally employ plumbers or professionals who are Gas Safe Registered to install boilers as they will adhere to building codes and follow safety guidelines.

A quality boiler that is properly installed and maintained would go on to serve you for a long time. Your boiler will take care of all your heating needs and let you enjoy a cozy winter.
How does a steam boiler work?
At the heart of a steam boiler is a cast-iron tank filled about halfway with water. A burner below the tank heats the water until it turns to steam. The steam rises up through a system of supply pipes to each radiator in the home.
What is steam boiler?
The steam boiler is an old convection heating technology dating back over 200 years and is most commonly found in old homes. Because steam boilers operate at a higher temperature than hot-water boilers, they are inherently less efficient than their hot-water cousins and are more finicky to operate. Like a hot-water heating system, ...
What is a two pipe boiler?
Most steam boiler systems in homes are either one-pipe or two-pipe systems. One-pipe (or single-pipe) systems use the same pipes to deliver steam to the radiators and to return water to the boiler. The steam rises up and the water falls down through the same pipes. A two-pipe system is relatively more modern and uses separate piping for ...
How long does a steam boiler last?
Steam boilers are generally reliable and can run for 15 to 30 years or more, but they need more maintenance and regular checkups than a gas furnace, for example. Many steam boilers should be checked weekly to make sure the water is at the right level.
How to tell if radiator is one pipe or two?
If there’s only one pipe connected to it, you have a one-pipe system. Two pipes—usually on opposite ends of the radiator—indicate a two-pipe system.
What is a one pipe system?
If there’s only one pipe connected to it, you have a one-pipe system. Two pipes—usually on opposite ends of the radiator—indicate a two-pipe system. Another clue is that one-pipe systems have no temperature control at the radiators; they must be all the way on or all the way off.
How does a one pipe radiator work?
Air is forced out through vents to allow the steam to enter the radiators. One-pipe systems have an air vent or valve on each radiator.
What is the thermostat on a boiler?
On a typical oil fired heating boiler in the U.S. the wall thermostat is controlling the hot water circulator, turning it on or off. It is the temperature of the water circulating through the system (sensed at the primary control on the heating boiler) that actually turns the oil burner on or off to re-heat the water.
What does a room thermostat sense?
Room thermostat senses the heat increase as hot water from the boiler passes through and radiates heat from heating devices nearby. See THERMOSTATS. Hot water continues passing through more distribution piping as it returns to heating boiler, flowing past.
Do you have to add cold water to a hydronic system?
That water is heated and circulates through the radiating devices. You don't normally have to add cold water to the system.
What is understading in heating?
An understading of the sequence of steps in the operation of a heating system, from the moment that a thermostat calls for heat until the moment that the thermostat stops calling for heat can help us diagnos and fix many heating system problems.
How does a boiler work?
How Boiler Systems Work. Many older boiler heating systems are gravity systems and rely on the fact that steam naturally rises to the highest point in the system. Contemporary systems, on the other hand, circulate hot water through the pipes at a temperature between 180 and 190 degrees Fahrenheit, which reduces the amount ...
What is a boiler system?
Whether it's old or new, boiler systems are closed systems in which water or steam continuously cycles through the heating elements and back to the boiler, and they are more energy efficient and easier to maintain than forced-air systems. The heart of the system is the boiler, a name from the days when most boilers actually boiled water.
Is a boiler a whole house?
Image Credit: didecs/iStock/GettyImages. Bo iler systems for whole-house heating are more common in older homes than they are in modern ones — mostly because central heating systems that include cooling and ventilation have largely replaced them. However, boiler heating systems, also known as hydronic heating systems, ...
What temperature does a boiler circulate water?
Contemporary systems, on the other hand, circulate hot water through the pipes at a temperature between 180 and 190 degrees Fahrenheit, which reduces the amount of energy needed to heat the water but requires the addition of a circulation pump. Whether it's old or new, boiler systems are closed systems in which water or steam continuously cycles ...
What is the heart of a boiler?
The heart of the system is the boiler, a name from the days when most boilers actually boiled water. Like the steam tanks of yore, many modern boilers are made of cast iron (though many aren't), but even though they circulate water instead of air, they operate almost exactly like furnaces.
How does a fuel heater work?
A fuel — which can be natural gas, propane, oil or electricity — produces heat, which is transferred to the water by a heat exchanger, and a pump circulates the heated water throughout the system. The water transfers heat to the elements in each of the individual heaters placed throughout the house and returns to the boiler to be reheated. ...
Why do boilers need expansion tanks?
Because water expands when it's heated, a boiler system needs an expansion tank, usually located near the boiler, to act as a reservoir and to prevent overpressurization of the system. If the boiler burns a fuel, it also needs a flue to exhaust combustion gases. To increase energy efficiency, boiler systems can be fitted with zone valves ...
