Energy Efficiency Auditing FAQs, answered by experts

The answer is a resounding yes, as dishwashers save significant water and energy compared to washing dishes by hand. The difference is so drastic in fact that those who use energy-efficient dishwashers can expect savings of over $450 per year. This is because dishwashers use less water, they wash at a higher temperature than a hand rinse, and you don’t need to rinse them after washing. New dishwashers use around 4 gallons per load, whereas washing by hand can use up to 2 gallons per minute.

If you want a new boiler that’s going to help lower your fuel bills, you should buy one that has a high energy-efficiency rating. For example, a boiler that is rated “A” uses at least 90% of the energy created by the boiler. And in order to enjoy the best performance, it’s important to have it installed properly by a highly-rated tech.

Some types of electric fireplaces use more electricity than others. Models that produce 1,500 watts will have more of an effect on your heating bill than 750-watt models. 

Electric fireplaces use an average of $1.85 of electricity every eight hours. These minimal operational costs aren’t likely to make a big difference in your electric bill—unless you’re using it as a primary heating source for your home and it’s running most of the time.

To find a reputable home energy auditor, start by researching local companies that offer the service and check their reviews, methods, and certifications. The most reputable professionals are often Home Energy Professional (HEP)-certified by the Building Performance Institute (BPI). You can also consult the Department of Energy’s certified list of energy auditors or use a state licensing tool to review local guidelines and ensure you are hiring a certified professional for your area.
