The boiler is going to be one of the most important units in your home. This is what you will use when you are trying to get the most hot water pressure from your shower or you are cold during the winter months. That is why it helps to know how to fix certain problems and perform regular maintenance on it.
One thing that you might need to do every few months is to bleed out the hot water boiler that is in your home. This works by using the water that runs through it and turning it into steam. This steam is forced throughout the home to heat it up. When it cools it will turn back into water. During this process water will become trapped inside certain parts and cause it to stop functioning properly.
Before you begin you need to turn the power to the system off and allow it to cool off. Attach a garden hose to the spigot that is on the return line of the boiler system and have the water supply connected and running to it. Make sure to place a bucket at the end of the hose so that it can catch the water.
Turn the zone valves from the boiler system and open them all that are on the radiator. Make sure to open the closed zones to bleed out first. Slowly move the feeding valve to where the water goes into the system and release the handle of the spigot at the same time. Turn it slowly each time the water pressure is higher than 25.
When there are no more bubble coming from the water than turn off the spigot on the hot water boiler systems. Close the zone valve and open the next one. Move your way through them all until they have all been bled.
