7 Best Hydronic Hanging Heaters

Whether you are an everyday homeowner living in extremely cold temperatures, trying to keep your basement warm, or maintaining a warm temperature for a professional workshop during the winter months… an affordable and hanging hydronic heater is a must-have. 

Finding the best hydronic system can help you save on energy costs as well as provide consistent heat within basements with concrete floors and block walls. Furthermore, the best hydronic hanging heaters are quiet, more durable, and cost-effective. Generally, you would want to size a hydronic garage heater based on the square footage of the area you want to heat. 

How Does a Hydronic unit heater work?

Hydronic heating works by using water to move heat through a variety of sources like boilers or heat pumps. This heat is then moved through pipes to each room. In effect, the heat is moved throughout a home or building using a sealed pipe network. While heated liquid must travel through the entire system, often it takes slightly longer to heat a space. Hydronic heating systems can be powered using several types of different energy sources. 

Difference between Hydronic Heater and Regular Heating?

Generally, when people refer to a “regular heater” what they are talking about is a duct heater. Which works by collecting cold air, warming it to a temperature set by a thermostat, and pushing it by fans through ducts. The Best Hydronic heating heater systems utilize hot water, outdoor wood boilers, or some kind of heat exchanger and then transfer heat through a series of pipes, that effectively heat through a home, basement, or commercial space. They essentially heat surfaces within a structure rather than heating the air.
