Consider flushing the system at least once a month during the heating season to keep things quietly moving. If you have a service contract through your utility company then it may be covered. If you are a hands on gal or guy then here’s
How to flush a heating system
1. Keep the service manual that came with the furnace handy
2. Open the air vents on all radiators located on the highest level of the house
3. Turn off the furnace’s power switch.
4. Shut off the furnace’s water supply
5. Let the furnace cool down
6. Attach a garden hose to the drain cock (faucet)at the lowest part of the boiler (usually at the rear) and lead the other end of the hose into a drain or bucket
7. Open the faucet. Let the line drain through the hose. (The water will be heavy and brown with rust and sediment)
8. When the flow slows, turn the water supply back on. Flush the boiler with fresh water. Do a few times.
9. When the water from the boiler runs clear, turn off the drain faucet.
10. Refill the boiler by opening the water supply until the furnace reaches its proper water level. The glass water-level indicator should be slightly more than half full
11. Turn boiler on
12. When you hear water filling the pipes, return to the top floor radiators and close the air vents. Open and close vents on all other radiators in the house to release any trapped air
Caution: You can crack the furnace by running cold water into a hot chamber so follow directions and take your time.
A home radiator that is cold at the top and warm at the bottom usually is a sign of trapped air. The radiator needs to be bled. Sounds like an episode of Dr. G, Medical Examiner. Here’s how to bleed a radiator for a steam and hot water system.
1. Turn radiator off. Give it time to cool down if it is not already cold.
2. Unscrew radiator air vent (looks like a mini-silo with numbers on its head). Shake out any trapped water and replace it.
3. Place a small pan and rags on floor where radiator is connected to the steam pipe.
4. Use pipe wrench to loosen connector. Disconnect radiator from the steam pipe.
4. Tilt the radiator (You’ll need help. The radiator is heavy cast iron) and drain any trapped water into the pan.
6. Slide a shim under the radiator so it tilts toward the connection pipe. This allows proper drainage for the steam return.
Hot water system
1. Turn the furnace off
2. Look for the bleed valve at the top end of one side of the radiator
3. Using a “bleed key” turn the valve counter clockwise slowly about a half a turn
4. You’ll hear the hissing sound of air escaping as your turn the valve. When water begins to come out close the valve.
FIRE HAZARD: This extension cord is overloaded and laying right on a carpet.
Every time I see an extension cord I am reminded of a friend whose first home office was a TV snack table and a desktop computer with a power cord tautly stretched across the bedroom to the electrical outlet. I know he had to step high or do the limbo to keep from tripping over the cord. When the desktop became a laptop after the snack table collapsed under the weight, he repurposed the hall closet into now-you-see-it-now-you-don’t office space.
There being no electrical outlet in that closet and the nearest one about 15 feet away in the bedroom, he linked three of the shortest extension cords I’ve ever seen and stretched them across the room to power the computer, monitor, printer and desk lamp. Only two plugs would fit easily into the extension cords at one time so he went out and bought a really long fourth extension cord for the last available socket and plugged in the two remaining pieces of equipment.
The longer cord had reach but only two openings so he just went ahead and force fed the three-prong cord for the monitor into the two-prong extension cord. How he is not being remembered today in the past tense or at all is thanks to the blessings God bestows upon babies and fools.
Those jerry rigged hookups could have triggered a fire and nearly did if the hot to the touch cord with its burn marks and disfigured casing at the plug end of his cords were any indication.
I bring the subject up because extension cords are big this time of year. Many are being used by single mom home-based catering services that are plugging in extra cooking appliances to meet the demand for baked goods and full meals. Then there are the Christmas trees, holiday lights and ornaments twinkling away in and outside our homes. Carelessness with extension cords will produce a fire somewhere.
Not every extension cord is the right one for every job. There are heavy duty and light duty cords and those made for interior use and those for outdoor use. Interior cords are generally not insulated for use in wet weather. Plugging one extension cord into another also is risky since that reduces the current carrying capacity of the cord which could make it overheat, cause a fire and or damage the appliance that is plugged in. To find out what extension cord you need read and match the UL ratings and usage labels attached to the cord and the appliance it is powering.
“Electrical fires in our homes claim the lives of 485 Americans each year and injure 2,305 more. Some of these fires are caused by electrical system failures and appliance defects, but many more are caused by the misuse and poor maintenance of electrical appliances, incorrectly installed wiring, and overloaded circuits and extension cords.” That language comes straight from the Department of Homeland Security's Federal Emergency Management Agency’s Fire Administration. Words to the wise.
Quick safety tips for extension cords
- Don’t force a three prong plug into a two prong cord.
- Don't overload outlets with multiple plug-ins and adapters.
- Safeguard equipment from sudden power spikes and outages with a surge protector power strip.
- Avoid piggy backing by plugging in multiple extension cords.
- Choose the right extension cord. Length should not be the only criteria. Read the cord’s UL label for gauge, capacity, use and wattage rating.
- Use a rubber strip to cover any cords strung across a walk area to avoid tripping or damaging the cord.
- Got small, crawling, curious children around? Invest in safety power strip covers.
- When plugging in Christmas trees, raise up the connection between tree lights and the extension cord to keep it from resting on carpet, tree skirt or any potentially flammable surface.
- Make sure outlets are grounded. One with three holes suggests it is grounded but have an electrician check for certain.

Savvy sisters, Nycole Pederson, Julie Tibbles and Tammy Nelson of St Paul, Minnesota heard the cry for help from design challenged yard signs. They put their heads together and gave the neighbors something sassy to talk about with their Sassy Signs and DeZine-A-Sign lines. From house sales to baby births, Sassy Signs will design it for you or let you do it yourself with their kit. When the sisters got great reaction from friends and neighbors for their sassy yard signs, they figured they were onto something. They combined their workplace talents to build their own enterprise. Nycole has a background in operations and IT. Julie is a whiz in business and finance and Tammy worked as director of retail development for Tommy Hilfiger USA. All three are married moms with 11 children between them. Their signs are available at selected Lowe’s stores and through their website.
Lisa Mears, 46, is a self-described neat nick who got tired of her family’s assortment of toothbrushes scattered on the bathroom sink. There wasn’t an existing sanitary central storage solution on the market to accommodate the range of brush sizes from slender to bulky - you know those superhero handles and battery pack ones. So, the Baltimore resident designed one. “I can’t even draw stick figures,” Lisa laughed amazed at the product she invented. With help from her then fiance, James Morris, and investments from family and friends Lisa raised $40,000 to get started. The resulting Cloverholder Toothbrush caddy, manufactured in Maryland, took 3rd place in the bath accessories category at the National Hardware Show in 2006. The invention also won Lisa recognition in June 2007 as "Woman Inventor of the Year" by the New Products Exposition (NPEX) organization in Pennsylvania.
Folks who have petite bathrooms and no shelf space will appreciate the wall mount version. The Cloverholder is available in colors too! And kids, parents and grandparents can easily customize it as a home project using craft paints in favorite colors and image decals. Here come the Smurfs. The Cloverholder toothbrush holder is growing in its availability and can be found at select retail stores. But Lisa advises, "It is available right now on the web at the Cloverholder website.
On the personal front, realizing what great business partners they were and that, coincidentally they were in love, the couple married one steamy August day 2007. The next month the busy couple headed to Florida where they shot commercials for their product that were scheduled to air in November and December in 100 major cities, 100 times, on Bravo, WE and WGN stations. Ah, the inventor's life.
If you’ve ever tried to plug in the charger cords for your cell phone and your ipod or power up your hair dryer and curling iron in the same outlet at the same time then you've felt Kim Gerard's pain. I know I cheered when she recalled how ticked off she was when she pitched her cellphone charger across the hotel room. The space hog chargers she traveled with for business would not play together in the one available electrical wall outlet. Rather than stay mad too long she decided to fix the problem and just go ahead and invent an outlet that worked with our modern day toys. "I sketched the idea out on a napkin," she said. The "idea" is an electrical outlet with plugs that rotate 360 degrees. Don't you love it? It helped that Kim has a background in civil and environmental engineering. In 2001, she received the patent and put the device through its safety and market paces. Now the 360 electrical outlet is available at a hardware store near you. If it ain't there, ask why not.
