Hot water heaters are one of the most common appliances found in every household. In the US, an average household spends about $400-$600 every year on water heating. It is the second largest expense that accounts for 14% to 18% of a household’s utility bill. This suggests that investing in energy efficient hot water heaters is the need of the hour.

Keeping the house clean is a never-ending task, and vacuum cleaners greatly help make this job easier. They help get rid of any dust and debris that may be hiding under the couch, behind cupboards, and under carpets. If one has not bought a vacuum cleaner in a while and is thinking of replacing the old one, newer models have great features like handheld and collapsible designs, as well as vacuums for suction and mopping.
