Boilers are a common way of heating homes, but it is important to know that there are different types of boilers to choose from. Understanding this knowledge will enable you to make the best choice for you.

What all boilers have in common is that they heat water to heat your home. However, in addition to distributing heat to heat your room in two alternative ways, they use different fuels, so different types are available.

We provide detailed information on all types of boilers and their functions and efficiency here, so if your home heating depends on boilers, you can make the best choice.

Let's start with the common ground of all boilers. The boiler is part of the central heating system and is intended to be the main heating system for the home.

All household boilers burn fuel or use electricity to heat water. They provide low-pressure steam or hot water to the room through a series of pipes. The steam is delivered to a steam radiator, and hot water can be supplied to a radiator or a radiant floor system-for example, hydraulic (water) floor heating.

There are three types of boilers: gas-fired boilers, oil-fired boilers and electric boilers. 

The gas boiler can use natural gas or propane. To use natural gas, of course you need to be in an area with a distribution system. If you live outside of these areas, propane will be delivered to your home and stored in storage tanks. Insufficiency? It is more expensive. 

Modern gas boilers are very efficient.

Oil-fired boilers are a common choice for people who live in places with limited natural gas supplies. You need to deliver the oil to your home and store it in a tank. Of course, the cost you pay for oil will be affected by fluctuations in oil prices.

If you like the idea of ​​using renewable fuels, you can get a mixture of biodiesel and heating oil from some companies to fuel your boiler. The US Department of Energy stated that this is a way to reduce dependence on foreign oil and utilize domestic resources. There is an additional benefit. "Compared with pure heating oil, biodiesel blends produce less pollution," the department said.

Electric boilers are the third type of boilers offered. Although these are winners in terms of energy efficiency, they are usually not the best solution for the home because the price of using this fuel is higher compared to other options in your area.

Want to know the difference between a boiler that provides steam and a boiler that produces hot water? Boilers that produce steam usually appear in older homes and must operate at a higher temperature than boilers that produce hot water. The Department of Energy stated that they are "intrinsically less efficient."

Or, boilers provide hot water for radiators (skirts or verticals) to distribute heat. In newer homes, these water heaters are second only to forced ventilation systems in popularity.

If you are considering upgrading to a modern boiler, it is important to note that its efficiency is shown by its AFUE or annual fuel efficiency. All new boilers must show this so that you can compare models.

AFUE is displayed as a percentage and reveals how efficiently the boiler converts its heating fuel into energy in a typical year. For example, an AFUE of 90% means that 90% of the energy in the fuel is converted to heat.

According to data from the Department of Energy, the efficiency of the old system—whether it is a furnace or a boiler—may be as low as 56% to 70%, while the new high-efficiency version can reach 90% to 98.5%. 

Key point: Upgrade your boiler from the old model to the new model, you can save a lot of money and reduce carbon dioxide emissions.

If you want to upgrade the boiler, you need to note that all boilers are condensing or non-condensing. It is called a condensing boiler because the flue gas is condensed in the second heat exchanger. This makes the boiler more efficient. For high-efficiency systems, it is the condensing boiler you need.

It is also important to specify a sealed combustion boiler at the time of purchase. One of them brings outside air into the burner, and at the same time discharges exhaust gas to the outside. Unsealed combustion boilers waste energy and risk bringing dangerous gases into your home.

Combination (combination) boiler is a model that can provide space heating and hot water at the same time, and it is a space-saving option.

Joshua Blackburn, the founder and design and construction director of Evolving Home, said: "The advantage of having a combined boiler is that it has high energy efficiency because it can be used as a domestic heater or as a water heater, and it can be used immediately."

"Combined boilers are very suitable for houses with little space because they are compact in size and are usually wall-mounted, so they can also save space."

Keep in mind that if you have a high hot water demand in your home at the same time, the combined boiler may not be suitable, so you should listen to the advice of a professional heating contractor.

The type of boiler that is best for your home depends on the fuels available in your area. If you want, natural gas may be the lowest cost option.

When it comes to boiler efficiency, the Department of Energy recommends that, “If you live in a cold climate, it usually makes sense to invest in the most efficient system. In a mild climate and low annual heating costs, change the efficiency from The additional investment required to increase from 80% to 90% to 95% may be difficult to justify. However, keep in mind that more efficient equipment will have lower emissions than equipment in the 80% range.

In addition to the importance of its type, it is also important to choose the right size boiler for your home. Boilers that are too small or too large will not operate effectively. Call a professional heating contractor and they can figure out the needs of your home.

The Department of Energy also recommends that you improve the energy efficiency of your house by installing effective house insulation materials before replacing the boiler.
