Mrs.B here.
New home owner, had to get my water heater checked out and thermastat replaced. Rinnai company gave me this company info, because they knew about this product. I had an exceptioanl experience with this company. Lennard had come out to my home order my parts explained everything to me. He left me with no question. He was a sweet guy and so was his staff. I strongly recommend this company. 100% great experience.
