How Does a Hydronic Boiler Work?

boiler-gaugeHydronic heating is one of the most popular ways to heat up a property in our service area, but many homeowners are not quite sure how it works. We don’t blame them—hydronic heating can be a bit tricky to understand. And besides, you have local heating contractors who know the ins and outs of hydronic heaters, so you don’t have to.

Still, it can be helpful to know about the basics. That way, you’ll have a bit more information when something goes wrong, when selecting a new installation, or when you’re speaking with technicians. Reach out to our team for boiler services and read on to learn what makes hydronic boilers so special.

A Hot Water Tank

The term “hydronic” refers to the fact that the boiler uses hot water to heat the home. This means, of course, that must be a heat source, and with a boiler that almost always means a set of gas burners. A pilot ignites the gas burners, which heat up the boiler throughout the day as needed.

The boiler is, essentially, a large tank of hot water. However, this is a bit of an oversimplification. It is carefully engineered to ensure proper pressure levels and safe temperatures are maintained, or else it has safety checks in place to ensure the system shuts down or drains water as needed.

The Pipes and Circulators

Hot water is one of the best methods of heat transfer, as long as you have some way to move it around the home! The circulating pump is what pushes water from the tank to the pipes that lead throughout your home. The pipes may circulate water underneath the floorboards, or to an endpoint. Often, when there is no heat from a boiler, or when there are hot spots or cold spots around the home, it’s because of a broken circulating pump.

Radiators and More

Many modern boilers use underfloor piping systems to distribute heated water throughout the home efficiently, but this isn’t always the case. Wall-mounted units and baseboard units allow for heat to be distributed to various rooms without the need for major renovations. Older heating systems or steam boilers may have radiators throughout the home, while newer homes rely on modern baseboard heaters that are easy to control.

What Makes Hydronic Heating So Special

The circulation of hot water is a highly efficient way to distribute heat to a home. Most heaters in this country are forced-air heating systems, meaning they heat the air and distribute the heated air out to the rooms of the home. Since heat naturally rises, though, this makes it difficult to hold in the heat, and air cannot directly transfer heat to our bodies with the ease of a boiler.

Hydronic boilers use hot water for heat transfer. Water holds heat more easily than air does, and it uses radiant heat transfer. Heat transfers from the water in the pipes to the floorboards to all of the people or objects in the room, which means you are more comfortable for less!
