How does a forced hot water boiler work? This type of system has a boiler for a heat source and heats the water inside the boiler. The heated water is sent up pipes throughout the house by either circulator pumps or zone valves. Vents in the baseboard then disperse the heat throughout the house. Provides fairly even heat with little to no drafts.
What are the disadvantages of hot water heating systems? A boiler heats up water, turns it into steam and pushes it throughout the home for heating purposes. The water isn’t necessarily potable, but can be used to heat pipes within the home’s walls, or heat a radiant heat system.
How do water boilers work? Also referred to as “hydronic systems,” FHW heats water in a furnace (or more accurately called “boilers”) fueled by oil or gas, and then it circulates that hot water throughout the home with a loop of baseboard pipes.
What type of heating system is forced hot water? Hydronic hot water systems are much like closed gravity systems, except a hydronic system uses a motor-driven circulating pump to move the water.

Why is ph3 boiling point lower than nh3?
NH3 molecules makes strong intermolecular H bonding b/w themselves. But due to lesser electronegativity of larger PH3 molecules, they cannot form Hydrogen Bonding b/w themselves. In NH3, there is hydrogen bonding whereas in PH3 there is no hydrogen bonding. Therefore, the NH3 has higher boiling point than PH3.
