I have been working on turning down the heat in our house but my suspicions are that what the thermostat says and reality are two very different things. So today I got my nerd on. I walked around the house with a temperature gun zapping everything and recording their temperature readings. You can measure the temperature of anything. Anything.
The results are interesting and confusing. I measured each spot twice, once during the day and once at night. The thermostat was at the same temperature the entire time. In some cases the temperature reading was higher at night than it was during the day. Which honestly, I don't understand so I am going to have to take more readings to rule out any flukes.
I measured walls, floors, ceilings, outlets, doors and windows. The most shocking reading was our master bathroom shower which read 10C/50F. I'm thisclose to taking a sledge hammer to it to find out what is causing it to be so cold.
By far I saw the largest variance with outlets. I don't know what made me think to measure them but I was zap happy and was just recording everything and anything. I had outlets on exterior walls measure at 11.5C/53F, one on an interior wall read 9C/48F and other interior wall outlets were in the 16-18C/61-64F range. Having safety covers in does not seem to make any difference.
Doors and Windows
Our doors and windows are crap, especially considering they are only 8 years old. The doors and windows themselves had very cold readings and so did all the areas around them. Our front door was probably the most interesting. The door itself measured 14.5C/58F, the window panes inside the door were 9.5C/49F and the window pane right beside the door was 9C/48F. The floor in front of each door....freezing.
We cant do a whole lot until the weather changes and the snow melts. At that point we can tackle looking for cracks outside. In the meantime I will be sealing any leaks I can find in the outlets and windows and replacing the weather stripping on the doors and windows that open.
Do you want to detect leaks but don't have a temperature gun? Follow these simple steps from the US Department of Energy:
- Turn off your furnace and shut all doors, windows and fireplace flues.
- Turn on all fans you have that vent outside like your bathroom fans, dryer and kitchen exhaust.
- Use a lighted incense stick to find leaks. The smoke will pull out of the house if you have a leak. If you don't have incense you can use your hand to feel the cold air.
Have you ever taken temperature readings in your house or used other methods to detect leaks?
