Using Bulbs to Generate Heat
What feasible options remain if you've been using incandescent bulbs as small sources of heat?
 
I use a 100W bulb to heat my small pump house in the winter to keep my pipes from freezing. I know they are changing the light bulbs that are available now, so what kind of light bulb can I buy that will give enough heat to keep my pipes from freezing, but not cost me an arm and a leg? The pump house stays sufficiently warm right now with the 100W.

Wow, my mom’s side of the family is from Alberta, Canada, and they needed to do the very same thing! I believe I have an excellent and economical solution for you. There is a certain class of higher-wattage incandescent bulbs that will not be discontinued. These are called "rough service" bulbs. These have an extremely long life of 4,000 hours, compared to 750 hours for a standard incandescent bulb. These bulbs are also available in shatterproof versions, which is a very nice safety feature. The best thing is they are under a dollar each.
