I had the EcoSmart tankless water heater installed in March 2015 after hearing how much a friend mine saved on his electric bills and what great, professional service he had experienced with Todd. Though it is hard to tell how much money I have really saved, with electricity costs constantly changing, I do know that I am using on average about 50 kWh a month since the tankless heater has been in place. Initially, I was using hundreds of hours as the standing water tank was a real electricity eater. The reduction in electric usage is important to me, and in talking to someone about the heater, I likened having a traditional heater to keeping a pot boiling on the stove all day, which we know is wasteful. I like the concept of the tankless heater and its on demand principle, too. It just makes sense. Todd Sharp is both smart and honest. He fully explained my options for heater replacement on his first visit, and did not try to sell me on anything. I had three estimates from three different companies when I did decide to buy the tankless heater, and Todd's fair pricing, prompt installation scheduling and his genuine pride and enthusiasm in his work persuaded me to work with him. On installation day, he arrived promptly, worked steadily on my challenging installation as the unit is in the hall closet under the stairs, and was attentive to every detail of both safety and care for my home. After the installation, Todd called to be sure the unit worked well and to be sure I was still pleased with it. After a year, I am still a little amazed at how quickly it heats the water and draws it steadily through to the second floor bathrooms. It takes about 10-12 seconds, even in cold weather to get the shower hot, and it keeps the temperature steadily while running. I recommend Todd Sharp and the Eco tankless heater. You can't go wrong with either!
