How bad is a 250 watt heat lamp bulb on electricity??
I have a shed in my yard that houses my water pump. I have a clap on lamp with a 250 watt heat lamp bulb in it to keep it from freezing. How bad is it on electricity?? I mean is it like running the dryer all day?? Or like the refigerator being plugged in and on, Or a lamp plugged in and on all day. Can I use a regular bulb to keep it from freezing also? If so what watt bulb will keep it unfrozen?? I feel like this is a stupid question but I think I am giving Dominion Power enough money right now to heat my house. All info is appreciated. Thank you
Jim N is right on, except that the electricity rate may be somewhat higher than 10¢ per KWH. Where I live, Southern California Edison charges on a graduated scale, much like the IRS taxes on a graduated scale. The more electricity you use, the higher the rate for the incremental usage. The top rate for residential use is around 30¢ per KWH, which would be $1.80 per day for a 250 watt heat lamp. You'd have to look at your electric bill to see what your incremental rate is.
Besides using heat tape or a heat blanket, another alternative is to leave a cold water faucet turned on so that it is running slowly all day and night. This will keep your system at the temperature of your well water, which will prevent freezing. Unfortunately, you'll use electricity to pump the water, so I don't know whether this would be more economical. But it is something to keep in mind in case your heat lamp burns out.
You need to trade off the cost of the heat lamp versus the cost and inconvenience of having to repair a broken water pump. I'm in favor of the heat lamp.
