Gas-Fired Boilers and Furnaces Department of Energy

An aquastat controls the temperature of the hot water in a boiler, typically keeping it around 180°F. But when heating needs are lighter in the spring and fall, that's actually higher than needed, and wastes energy. A modulating aquastat, also called an outdoor reset, senses outdoor temperatures and adjusts the hot water temperature accordingly.

Different Types of Radiator/ Boiler Systems Hunker

Next to forced-air heat, a boiler-and-radiator system is the most common type of heating system in cold-winter climates. All boiler systems use hot water to heat the home. There are two main types of boilers—steam and hot water (also known as hydronic)—and many more types of radiators or heating appliances, the units that transmit the heat into the rooms.

In this system the air flows back towards the boiler and is eliminated from the system by an air eliminator. Some vapor system utilize vacuum air vents to rid the system of air. Vacuum air vents permit air to leave the system but when the system cycles off air can not reenter the system through the vacuum air vents.
