Home Heating System: Improve the Heat in a Cold Bedroom
Homeowners know when they are cold and they know where their cold. They might not know how to light an airplane pilot light, or air seal an attic floor, or balance a home heating system, but they know when they're cold. Bedrooms will often be the coldest room inside your home and most often people just live with it. Stick your child in the cool bedroom, throw a few extra blankets for the bed and let them know to finish their homework.
Handling a cool bedroom is frustrating. If you turn up the heat to warm the area, the rest of the house gets too warm. Shut every one of the heating registers except the bedroom and it puts excessive back pressure on the furnace. Too often a household try to adjust the temperature of just one room by closing heating registers in other rooms and very quickly they have half the registers inside your home closed and the heat system working overtime to meet the heating request with the thermostat.
Usually, the home heating system is designed with a professional Heating Contractor that attended HVAC school for a lot of hours a week for assorted years. A Heating contractor must pass a student program before he or she can even take the test because of their journeyman license.
In the educational phase in the heating and cooling training, they are taught how to perform a heating load calculation on a home. They take the heating load and build a designed heating system that includes furnace size, fan capacity, duct size, air flows, and register size. Put simply, heating systems are designed to heat all rooms evenly and also to work as a system with all of registers open.
When you have one bedroom that is cooler than the remaining portion of the house, one of two things has happened:
The home heating was designed by a contractor that barely passed the test, or
the heating system is broken.
Recently, I'd a homeowner complain they got very little air flow out of the heating register in their dining room. The dining-room was cooler than other regions of the house. With a flow hood, I registered a 75% loss of air flow at the register when compared to the register in the family room. I removed the register grill, took a flashlight and mirror and looked along the inside of the heating duct.
With the mirror to see around the initial elbow, I saw that a flow damper valve was placed in the heating duct. Further inspection demonstrated that all the heating ducts in your home had a flow damper installed close to the registers. The damper in the dining room was alone that was closed the majority of the way. The homeowner has not been aware that flow dampers were element of the homes heating system.
Heating Duct Damper
Flow dampers can be a bit unusual inside my neck-of-the-woods, I don't see them often. Flow dampers are put into a heating system to allow manual adjustment from the flow of air to the registers. With dampers, the flow of conditioned air can be balanced so warm and cool areas of the home can be eliminated. To keep from putting increased pressure for the furnace fan motor, when one damper is not open another damper should be opened.
Sometimes, I believe an electric heating contractor may toss in a bunch of flow dampers when he looses his pencil and cannot be sure of how big to really make the heating ducts or how many registers need to be in a room.
6 Approaches to Boost the Heat in the Cold Bedroom.
Repair Heating Duct:
Often there is the possibility that the duct system includes a problem that can be fixed. Ducts can be partially or totally disconnected and versatile ducts can become pinched off or collapsed. Here is the first and most important fix taking into consideration the cold bedroom. This fix doesn't only warm the bedroom, but also increase energy efficiency and energy savings.
The first step is the inspection of the duct leading through the plenum to the register to make certain it is securely connected. Also, look for holes, crimping, or collapsed areas. Heating ducts damaged by animals is a possibility that you should look for.
Disconnected heating ducts could be reconnected, but damaged heating ducts frequently need to be replaced since they are difficult to repair.
Look into the Damper:
The sneaky heating contractor may have placed a damper within the heating duct and kept it an excellent secret. Look and feel inside duct by taking out the register cover. Also, remove insulation externally of the duct, especially near the register and check for the telling signs of a damper. A metal rod with a small handle and some anchor screws indicate a damper inside. Open the damper plus your cool room problems maybe over.
Balance Room Pressure With a Cross Over Duct:
Now we must talk about room pressure and balloons. Crack bed door open about an inch, turn the furnace on and see if the pressure builds up within the room and closes the door.
The heating system can be a circle of air. Air is heated from the furnace, pushed over the heating ducts right into a room and then sucked by the same furnace, out of your room, back over the return air duct on the furnace. If the air space cannot get back to the furnace, the space builds air pressure, being a balloon, which restricts the flow of conditioned air in the room in the first place.
To comprehend pressure in the bedroom, the conditioned air is forced through a different duct and into an adjoining room.
To repair the potential problem, many homes have overlap ducts installed in the ceiling or higher the door that allow the environment in the room to get back into the hallway even when the door is closed. In a few larger, higher priced homes, they may have eliminated the room pressure problem by using a return air register in each and every room.
To balance the area pressure and stop this challenge, the two most used repairs are installing a overlap duct through the wall within the door or simply cutting the bottom of the door off so there is a wider gap relating to the door and the carpet.
Increase the Size of the Duct:
Maybe the Heating Contractor ran beyond 8 inch ducting so he decided 6 inch was close enough. There is a real possibility that this back bedroom is cool as the heating duct system wasn't engineered correctly. During these moments, the best fix is to correct the mistake and replace the duct with a larger one. If your home is fairly new as well as the Contractor is still around, you will get this done like a freebee.
In this way, the cool room will have a larger share from the air coming from the furnace. This repair can nevertheless be a do-it-yourself'er if your willing. Heating duct material, both ridged and flex, are available at your favorite home store. Some zip ties, a couple of sheet metal screws, a clear knife and a pair of tin snips must do the trick.
If the heating duct sizing is simply too small to service the room, besides replacing the duct which has a larger one, the one other fix that might work is installing a booster fan within the duct or adding a whole second duct and register.
Duct Booster Fan
Convey a baffle in the heating plenum:
This adjustment can be extremely effective - particularly in a manufactured home. A bit of the main heating trunk ( the plenum ) has to be opened up so steel baffle or shield may be placed in the main trunk line which will direct more air in the heating duct which goes to the cold room. This can be a very effective way to grab numerous conditioned air that passes on the main heating trunk and direct it inside the direction you want it go. This is an inexpensive and permanent fix that works well very well.
Install a Booster Fan inside the Duct:
This $30 part won't create more heat, but it'll pull more heat on the cool room. The booster fan must be installed as close for the offending room as you possibly can and can be wired directly time for the furnace fan hence the booster fan will run every time the furnace occurs. Installing it can be a pain. An area of round metal duct either must be dropped down or added to the system. Be sure the duct system is air sealed or this added fan will pull unconditioned air in to the system and lower your efforts efficiency.
I know dealing with a cold spot at your residence can be a frustrating ordeal. Hopefully I have provided some answers to the problem that will be right for you and your home. The home heating system was designed to provide the comfort you are expecting and deserve and, after a little T.L.C., can provide years of energy efficient service.
