The first type of boiler is a hot water circulated type of boiler. This has water running from the boiler all the way up to the highest point of the home. The second type is a steam boiler, which sends steam through the radiators that could range up to three or more stories off the ground. In a hot water circulated boiler, there needs to be a certain amount of pressure to get that water a few stories up. For every pound of pressure, water is lifted two feet. That means 20 pounds of pressure would raise the water 40 feet. A common problem is that there is not enough pressure.
