:359 Cold Surface Condensation

Take the 1:5:10:365 challenge: Do one thing – for 5 to 10 minutes – 365 days a year to make our home and planet environment better.

1:5:10:359 EcoTip: The dew point occurs when temperatures on a surface are cold enough to cause condensation to form. If this happens on the outside of a can of soda – its not such a big deal – but if it happens on or inside wall or building cavities – the condensed water can result in damage and mold growth.

 Additional Information:

The blue area in the thermal image shown above is missing insulation. If the indoor temperature is 68 degrees F, and the humidity is 50% condensation will develop if the surface temperature hits approximately 50 degrees or less. The condensed moisture can result in water damage and mold growth.

:328 Check Supply Registers

Take the 1:5:10:365 challenge: Do one thing – for 5 to 10 minutes – 365 days a year to make our home and planet environment better.

1:5:10:328 EcoTip: The vanes on supply registers (the registers that blow the air into the room) should be installed to blow the air toward the middle of the room – not at cold exterior walls. In winter cold spots on walls may result in condensation forming when warm air is directed at them. The warm air hits a cold surface that’s temperature is below the dew point – condensation will form. Walls with condensation are more likely to grow mold. By blowing the air away from walls it can mix with the room air making condensation on the wall where the air hits it less likely.

:315 Defrosting Frozen Pipes

Take the 1:5:10:365 challenge: Do one thing – for 5 to 10 minutes – 365 days a year to make our home and planet environment better.

1:5:10:314 EcoTip:  If your plumbing does freeze – open the spigot anyway, it may relieve enough pressure to prevent the bursting of the pipe. Monitor the situation carefully so that if the pipe has burst, you will catch it quickly after the pipe defrosts. To melt the frozen plug use a blow dryer (not an open flame) and begin heating the pipe at the spigot working backwards towards the frozen point. If it starts to run from the spigot (even slowly) that will usually be enough to help melt the blockage.

:314 Emergency Pipe Protection

Take the 1:5:10:365 challenge: Do one thing – for 5 to 10 minutes – 365 days a year to make our home and planet environment better.

1:5:10:314 EcoTip:  If you believe your plumbing is at risk of freezing and bursting, you may be able to prevent that from happening by opening the spigot at the furthest faucet along the plumbing line and let it drip. Of course this wastes water, but it is likely to waste far less than if the plumbing were to burst. If you decide to catch the water in a bucket for later use, let it run directly into the bucket. Never leave hoses connected to spigots in the winter. The hose is more likely to freeze all the way back to the spigot causing a rupture.

:313 Winter Thermal Imaging

Take the 1:5:10:365 challenge: Do one thing – for 5 to 10 minutes – 365 days a year to make our home and planet environment better.

1:5:10:312 EcoTip: Winter thermal imaging can be effectively performed anytime the temperature difference between the inside and outside 20 degrees F or greater. The temperature difference is necessary so that cold spots such as missing insulation and air infiltration can be observed. This is a good way for checking to see if insulation in wall cavities or attics with plumbing are adequately insulated to prevent freezing of pipes.

The missing insulation shown in this Fluke thermal image shows up as being cold. If there were plumbing in the area where the insulation is missing – there would be a risk of it freezing in a cold snap.

A thermographer qualified to perform energy audits should be able to take the information gathered during a thermal imaging scan of exterior walls with plumbing and calculate the outdoor temperature that would be cold enough to cause plumbing pipes to freeze. By having this information you can monitor weather reports and take additional precautions during cold snaps when your plumbing is at risk.
