System, apparatus and method for heating homes and other buildings

A sealed heating system for a building, the heating system being under pressure and comprising:

• at least one heat exchanger within a first room of a building;
• a pressurized hot water boiler in a second room of the building, the boiler being configured to heat water;
• a first pipe portion having a first end, an opposing second end, and a longitudinal axis extending therebetween, the first end of the first pipe portion connected to piping that returns water from the at least one heat exchanger to the boiler, the longitudinal axis of the first pipe portion extending vertically;
• a second pipe portion having a first end, an opposing second end, and a longitudinal axis extending therebetween, the first end of the second pipe portion being connected to piping that supplies water to the at least one heat exchanger from the boiler, the second end of the second pipe portion being at least indirectly connected to the second end of the first pipe portion, the longitudinal axis of the second pipe portion extending parallel to the longitudinal axis of the first pipe portion, the second pipe portion being laterally spaced-apart from the first pipe portion;
• a first pump within, attached to, or fluidly connected to the second pipe portion;
• a valve located in or proximate to the second end of the first pipe portion, the valve allowing sediment to be flushed from the first pipe portion;
• and
• a port located proximate the first end of the second pipe portion, the port allowing at least one of (i) gas to be removed from the second pipe portion and (ii) fluid to be added to the second pipe portion,
• wherein the connection of the first pipe portion to the second pipe portion allows the first pipe portion to be adjusted during assembly with respect to the second pipe portion about a vertical axis.

• a first pipe portion having a first end, an opposing second end, and a longitudinal axis extending therebetween, the first end of the first pipe portion being configured to connect to piping that returns water from a heat exchanger in a building to a pressurized hot water boiler in the building, the longitudinal axis of the first pipe portion extending vertically or at least substantially vertically;
• a second pipe portion having a first end, an opposing second end, and a longitudinal axis extending therebetween, the first end of the second pipe portion being connected to piping that supplies water to the heat exchanger, the second end of the second pipe portion being connected to the second end of the first pipe portion, the longitudinal axis of the second pipe portion extending parallel or at least substantially parallel to the longitudinal axis of the first pipe portion, the second pipe portion being laterally spaced-apart from the first pipe portion;
• and
• a valve located in or proximate to the second end of the first pipe portion.
