If you’re like me you’ve long heard how keeping your home at a constant temperature will save money in the long run rather than programming it to be lower overnight and when you are not home. Well, now it turns out that they say homeowners may be able to save as much as 20% on heating bills by using a programmable thermostat that allows the temperature setting to fluctuate as much as 5-10 degrees. I might just be able to save enough to start seriously looking at copper sinks yet! This is just in time for we folks in the northern hemisphere to start thinking about making a change to a programmable thermostat before autumn starts in another 6 weeks or so.
