When a hot water heating system broke, my spouse looked into tankless hot water heaters.
Since he and I were the only ones in the house, he thought the tankless hot water heating system would be more efficient for us. We used our dishwasher which heated the water on it soon. We only use cold water for washing clothes. The main reason for having hot water was for cleaning and bathing! With a tankless hot water heater, we did not need to use a lot of electricity as we did for our 70 gallon hot water heater. The tankless hot water heating system also took up less area than the hot water heater, but my spouse and I sat down and discussed this in length, because the tankless hot water heating system was also more expensive! I read all the information he gave me. I realized that running the tankless hot water heating system was going to cost us 1/3 less in energy than it costs us for the electric hot water heater, even though during the winter season the electric hot water heating system was turned off and we were using our boiler to heat the hot water, we still had a higher energy bill. When we had the tankless hot water heating system installed, I couldn’t guess how suddenly the hot water got to our pipes. With the boiler, we had to let the water run for almost 5 minutes before the hot water reached the tub, but with the tankless hot water heater, it was five seconds. We saved almost $20 a month on our electric bill and realized the tankless hot water heating system was perfect for us.
