Temperatures are falling rapidly, and some regions of the country have already seen snow. With winter settling in, renters and homeowners are cranking up their thermostats to stay warm and cozy while bracing themselves for a big bump in utility bills due to heating costs. Savvy consumers looking for a way to save money without sacrificing comfort might ask: Can I cut down on my winter heating budget if I lower the thermostat and make up the difference with an electric space heater?

Fuel Matters

Savings are possible, though, no matter what kind of central heat you have. According to Grist magazine, if you are using a space heater for less than one half to one third of your living space, and you lower the temperature on your thermostat for the rest of it, you can save money even if your main heater is an efficient gas model. So if your family spends most of its winter indoor time in just a few rooms of the house, go ahead and experiment with a portable heater and see if you can reduce your bills.

For even more savings, don't forget to take other steps to winterize your home, like sealing any drafty areas and hanging heavy curtains. Wear a sweater, too, so you can minimize the amount of time you need the extra boost in warmth from your heater.

Finally, avoid kerosene heaters if at all possible. They pose a greater fire hazard than electric models and can affect your indoor air quality. If they are your only option, take extra care to comply with the safety instructions. Only refuel outside and be sure the indoor space where it is used is properly ventilated. Some kerosene heaters are even illegal in certain areas, so be sure to check your local laws before you buy.

The federal Energy Star program does not rate portable heaters, but the Energy Department does provide more information about specific types of space heaters.

The list of rules to be followed when installing new electrical systems into a building are related to the specific rules of the state, as well as certain minimum requirements laid down by Federal law. So in some senses the United States does not have a unified Electrical Building Code, because often there are variations between different states.

It was to address exactly this issue that the National Fire Protection Association, a panel of nineteen different bodies, began publishing the National Electrical Code (NEC) in 1897, and now every three years, in order to arrive at a single source of rules that should govern electrical installations. The current version was published in August 2010 and runs to over 1000 pages.

Whilst the NEC is not law as such, in practice it has been adopted by most states as their set of rules for electrical installations and wiring in buildings (with a few changes here and their depending on the state you are in), and so is now in practice the Electrical Building Code for the United States.

This is the book that all Journeyman Electricians will consume when undertaking their training, as it is pretty much the standard version across the country.

Though there are some differences between the states, and you can see the individual requirements for your state here: State Regulations

If you are planning on installing electrical wiring then you should refer to the NEC and your local Electrical Building Code for specifics and to the link above for any state specific requirements that you need to know.
