Microwave vs. Stove - which one is more energy efficient?

energy efficient microwaveYour microwave is a much more efficient way to heat or reheat than your stove top, mainly because your stovetop wastes quite a fair amount of heat. Your microwave uses about 80 percent less energy than your stove for heating up relatively small amounts of food. 

Even though your microwave uses a lot of electricity, it’s a small burst of power vs. the long, delayed energy used to heat up your stove. Of course, you can save some of the energy you’re using on your stove by using pots that are size appropriate to the burner. The EPA warns that using a six inch pot on an eight inch burner can waste the majority of the burner’s heat.

You can heat up a cup of ice cold water to boiling in an 800-watt microwave in 2.5 minutes. To find out how much energy that would take, you calculate the amount of electricity used in kilowatt hours (kWh) by taking the device’s wattage and multiplying it by the time. So 2.5 minutes = 0.042 hours, and 800 watts is .8 kW. Multiplying kWh capacity by time, we get .8(0.042) = .034 kWh to heat the cup of water.

So, when you want a great reason to do dinner the easy way and need some scientific numbers to back it up, refer back to this blog and pop that plate in the microwave - to save money of course.

What is GFCI protection and how is it maintained?

Monday, May 6, 2019

Ground Fault Circuit Interrupter (GFCI) devices are required in specific areas of our homes by law.  We must all have GFCI protection in certain parts of our house such as our kitchens, bathrooms, unfinished basements, outside our homes as well as our garages. GFCI devices monitor the electricity between the ungrounded (hot) and grounded (neutral) conductors. If there is an improper imbalance between the two conductors the GFCI will stop the power from exiting the receptacle, so no one gets an electrical shock.

Service was above and beyond excellent. Stuck with us and the power company until the true root of the problem was found. Worked around our schedule and budget restraints. Left things clean and was very respectful. Would definitely recommend him and use him again.
