Different Types of Boilers | Steam & Hot Water Boiler

Both hot water and steam boilers use a heat exchanger as a tool to heat water and distribute it to a piped system connected to radiators around the home. Steam boilers work by utilizing pressure and gravity to deliver hot steam to radiators and cycle cooled condensation back into the boiler to be reheated.

How to Recharge an Expansion Tank on a Hot Water Boiler

Note: An expansion tank is not found in steam boiler systems, which create heat by circulating hot vapor rather than hot water through the pipes and radiators. Steam boilers are simpler systems that lack several components found in hot water boiler systems—such as the circulating pump, expansion tank, and regulators for water pressure and temperature.

How to Reduce Boiler Pressure in an Older Boiler

Step 1 - Pressure. Boiler pressure builds up in the system. The way to reduce it is to bleed the system by letting air escape. The boiler feeds a closed circulation system. By expressing air from the system you reduce the pressure in the system. You can then adjust the pressure level later by turning on the feed of cold water to the system.
