Types of Boilers​

Do you have a boiler that isn't working? Are you in the market for a new one? Moving into a new home with a type of unit you're not familiar with? Guaranteed Service can help with any of these situations and make sure that you know exactly what you have and what kind of system would work best for you and your family.

Boilers come in many different varieties, each having specific characteristics for different purposes, such as:

Steam Boiler
Steam boilers use a heat exchanger to heat water and distribute it to a piped system connected to radiators around your home. They work by using both pressure and gravity to deliver steam to radiators and cycle the cooled condensation back into the boiler to be reheated.

The steps of steam boiler operation include:
  • The system is partially filled with water
  • The water is heated, in turn producing steam
  • The system's pressure increases
  • Steam travels up through the pipes and into the radiators
  • The air vent on the radiator opens
  • The vent closes once steam reaches it
  • The radiator emits heat
  • Steam then cools and condenses into water
  • The cooled water travels back to the boiler to then be reheated

Water Boiler
Water boiler heating systems use pressure, volume, and temperature to provide safe and efficient heat to the radiators or baseboards throughout your home. They use one or more pumps to circulate heated water throughout your home.

The steps of water boiler operation include:
  • Your thermostat calls for heat
  • The burner (oil or gas) is activated, in turn heating the water in the boiler
  • The pumps then either begin pumping the water throughout the system or wait for the water to heat to the desired temperature before pumping
  • The heated water expands, and the extra volume is stored in an expansion tank
  • The water goes to the radiator or baseboard, making heat radiate from it
  • The water cools
  • The cooled water returns to the boiler via gravity or a separate pump
  • The cooled water flows back to the boiler to be reheated

It should be noted that water boilers are not the same as water heaters. Water heaters heat the water for your shower, dishwasher, or tap water. Water boilers can be used to heat tap water in a separate tank, but the water for heating the radiators and tap water are kept separate.

Natural Gas Boiler
Gas boilers are fueled by natural gas that is sent through a line that runs from the street to your home. They also sometimes use propane gas from a large tank placed outside the home when there is no mainline for natural gas.

Natural gas is regulated by a temperature gauge and a thermocouple to minimize fuel usage. The gas is used to maintain a pilot light, which heats the coils in the boiler, passing the heat to the water in the tank.

Electric Boiler
Electric boilers do not use any fossil fuels, such as gas or oil, to bring heat to your home. They are popular because they are very efficient and environmentally friendly. There are no exhaust fumes and no need for a main gas line or fuel supply. They also tend to be quieter and take up less space.

Electric boilers seem like an easy choice, but along with them come the following disadvantages:
  • Electricity is fueled by coal, gas, and oil power plants which negates the "green" appeal
  • The cost of electricity is higher than natural gas or oil
  • They may not be able to heat a larger property as well
  • When there is a power outage, you have no heat

Oil Boiler
Oil boilers are water-based heating systems that are fueled by oil. These are more common in areas of the state with more limited access to natural gas. A separate oil tank, often containing heating oil blended with domestic biodiesel, pumps the mixture into your oil boiler to heat the water inside it and then sends hot air or water through the piping in your home.

Oil boilers can be very inefficient. If your unit has a natural draft, continuous pilot light, or a heavy heat exchanger, it's probably not environmentally friendly. With the number of options available today, most customers choose to replace their oil boiler with something easier to maintain and cheaper to fuel while also being better for the environment.

Condensing Boiler
Condensing boilers utilize two separate heat exchangers: one to heat the water before it goes out to the radiators or baseboards, and a second one to reheat the water returning to the system. Condensing boilers use the energy potential in exhaust gases to preheat the return water to the boiler. The result is a significantly increased efficiency.

Condensing boilers work by using natural gas to heat the water inside your home's boiler system. A pump then pushes the heated water through your pipes before heating the radiators or baseboards, which in turn heats the rest of your home or building. When the water circuits its way through the pipes, it begins to lose its heat, which is when the cooled water reaches the boiler again. The water goes through the heat exchanger, warms up once more, and the process begins again.

Condensing boilers are considered to be much more energy-efficient than regular gas ones. The carbon-based fuel used by gas boilers produces a chemical reaction of carbon dioxide and steam, which then escapes into the air through a chimney called a flue. This causes heat to escape, wasting energy and costing you more money to use. Condensing boilers have the flue gases pass through a heat exchanger, which subsequently heats the excess water while reducing the amount of energy expended by the boiler.

Pros & Cons of Boiler Heating Systems

All boilers work by heating water, not air. The water then goes through copper or PEX tubing throughout your home and is connected to your radiators or baseboards. Heat then radiates through your home, ensuring a consistently comfortable temperature.

Boilers present several advantages for efficient heating during the cold winter months, but they can also present issues that you would not have with a gas or electric furnace. Before you decide on which one to install or if you're considering changing to a different system, call the New Jersey boiler specialists at Guaranteed Service to help you make the best decision for your family and home.

The Benefits of a Boiler

Forced air furnaces do a great job of heating your home when it's cold out, but there are also advantages to choosing a boiler for your home instead.

Unlike a furnace, boilers don't make any noise when running properly. New furnaces have drastically cut down on noise, but a boiler will always guarantee silence.

In addition to much quieter operation, boilers are also known for better indoor air quality. Because they don't blow air, this means dust and other allergens that are normally blown around and released into the air by a forced-air furnace will be significantly reduced. You will save money on duct cleaning while enjoying cleaner air.

The Downfalls of a Boiler

While boilers are quieter and provide better air quality, they do not provide a way of cooling your home during the summer months. An entirely new and separate cooling system must be installed for cool air circulation.

Indications of trouble with your boiler may be gurgling or bubbling noises in your pipes, causing it to stop producing heat or even begin to leak. Since there are more parts in a boiler than a furnace, it can be time-consuming and more difficult to repair.

Some of the most common boiler problems include:
  • Loss of pressure
  • Dripping and leaking
  • Radiator or baseboard not getting hot
  • Pilot lights going out
  • Freezing pipes
Be sure to perform regular boiler system maintenance to ensure you don't find yourself in an emergency and stuck in a freezing house in the middle of winter.

No matter which type of boiler you have in your home, Guaranteed Service is here to get you through the winter.

When is it Time to Replace my Boiler?

Here's a question we see homeowners asking a lot, "When should I replace my boiler? It's a tough question for a homeowner to answer objectively because it's so darn expensive to replace a boiler. But you know you need to say goodbye at some point.

So, when is the best time to do that? Here are 3 signs that it's time to replace your boiler:

Your Boiler has Reached "Retirement Age":
Boilers live an average of 20-25 years, depending on if you had it professionally maintained or not. Age isn't everything, though. The cost to keep the boiler running will give you more concrete reasons to replace or not.

Increased Cost and Frequency of Boiler Repairs:
Like an old car, an old boiler that starts to have costly breakdowns is signaling that it's near the end of its usable life and needs to be replaced soon. The question then becomes, "How expensive does a boiler repair need to be before it's not worth it?" It depends on how old your boiler is and the cost to get a new boiler. A good rule of thumb is, no matter the age of the boiler, if the cost to repair is 50% of the cost of a new boiler, you should replace it. But for less expensive repairs, you should be less resistant to replacing the boiler the older it is.

So, if your boiler is 20 years old, and the cost to repair the boiler is only 10% of the cost of a new boiler, you should probably replace it (because it's more likely to break down again soon).

Your Heating Bills Have Risen Dramatically Over the Years:
Even if your boiler has a few years left in it, it may not be cost efficient to keep it if your energy bills during the heating season are high due to the boilers' horrible efficiency. With that in mind, you need to assess how much it's costing you just to keep the current boiler you have versus how much you'll save with a new boiler.

Weigh the Factors Together
As you can see, none of these factors (age, cost to repair, energy efficiency) alone can tell you if you need to replace your boiler. They should be weighed together.
