Boilers are an essential part of any heating system. They transfer energy from one source to another using heat. Boiler furnaces heat water, which then flows through copper piping and radiator valves to warm the air in the building.
There are many types of boilers, gas, electric, natural gas, combination, and system. Depending on the kind you use, they are powered by electricity, oil, or natural gas. The cold water enters the system and passes over the heating coil. It heats up until it boils, then flows through a closed system, building up pressure.
As winter comes, it’s important to make sure that your boiler is running smoothly. Issues such as leaks or fractures can be caused by improper installation. High-temperature winds can cause corrosion, making it harder to use fire when needed.
It’s also important to monitor the water levels and use hydronic controls to control the heating in each room. Professionals may be called to help manage the HVAC system and prevent damage from high pressure or low heating capabilities.
