Why is a boiler better than a furnace?

This is efficient because water holds 3500 times more heat than air. This makes a boiler more efficient than the so called “high efficient furnace”. Here is how: when the thermostat tells the boiler its cold, the boiler turns on and heats the water up to a set temperature and then turns off. The hot water is then circulated through out the house, heating the home as it flows. Since the water holds 3500 times more heat than air, it doesn’t cool down as fast as air. Therefore heating the house for a longer period of time, the boiler is off while the water is heating the house. When a furnace turns off the air immediately cools causing the furnace to turn off and on constantly. While a boiler is OFF most of the time saving you money, a furnace is ON most of the time costing you money.
