Tip & How-To about Heating & Cooling
If you have a water heating system where you use hot water to heat your home, you may have to bleed your baseboard radiation or cast iron radiators which ever you happen to have installed in your home.
Any time you let the pressure out of your system you can get air into it. For the system to work properly and quietly you need to release the air out of the system.
To properly bleed air out of your system you will have to make sure that the pressure reducing valve is working correctly and is keeping your system pressurized properly.
This tip will tell you about that and shows you a picture of what it might look like.
The next thing is to find the bleeder valve or valves on your system. Some systems will have many bleeders. Cast iron radiators will have one on each radiator near the top and baseboard heating systems will have one per loop at the highest point of each loop. When you open the bleeder you will get a foul smelling air out of the bleeder valve. Leave the valve open as long as air is coming out of it. If it is spitting and puttering, leave it open and catch the water till it comes as water only. This process can take a long time for some systems.
To open the valves sometimes you may need to use a special tool. Some valves have a four sided stem and others may have different configurations. Some you can get too with a needle nose pliers and others will accept a screwdriver. Many of the special tools can be found at stores like Lowes or Home Depot. HVAC supply houses often have them also.
The bottom line here is that air in your system is not good it will decrease the heat output of your system and you will hear the water running through the system when it should be very quiet. Releasing the air from your system will ensure top efficiency and performance of your heating system.
