My family recently moved into a new home and knew that the existing water heater was quite old and was running on borrowed time. I had to be proactive and thwart any impending disaster. However, I wasn't sure if a tankless water heater was the right solution for us considering the substantial upfront costs versus a traditional tank water heater. After discussing the pros and cons with Sal from DRF, I understood that going with a tankless would potentially save me the hassle of installing another tank water heater in another 10-12 years. Also, after doing some number crunching I realized that in the long run I would be paying for a tankless no matter which option I decided on. It was a no brainer. The two key benefits of going with a tankless for me is the savings from not constantly boiling water (whether I used it or not) and the potential of a disastrous flood in my basement. Andrea R. from DRF was also extremely helpful in answering any questions. At no point did I feel any pressure from them. I decided to go with the Rheem ECO200. Mike P. and Donovan arrived and assessed the basement space and quickly figured out a plan of attack to install the tankless. They clearly explained everything that needed to be done and got to work immediately. The installation was quite involved with water pipes, gas lines, venting, etc. so it took all day basically. At the time of writing this review, it had been a couple of weeks of using the new water heater and it has worked flawlessly since. It was obvious that Mike and Donovan installed the unit correctly the first time. DRF is a great company to work with and would use them for future projects. I was treated professionally and courteously and it's apparent that customer service and quality is very important to them.
