"I purchased a new Navien NPE-240A2 Tankless Water Heater and had it installed. I'm loving the new water heater. It replaces an old Noritz tankless that died just before this installation. The on-site estimate was what sold me. Ken went through all the details and answered a lot of questions from me. Zachary came out with Austin and performed the installation just like I discussed with Ken. Zachary kept me in the loop throughout the installation to ensure I was in agreement with how it was going. Zachary always had my interest at heart and ensured no corners were cut. The installation is much cleaner, and more correct than the previous tankless company did. Zachary even listened to my concern about the astectics of the exterior exhaust and quickly found an easier and cleaner looking way to address my concern. He also removed an old recirculation pump and replaced a new main house shutoff valve. The entire area was treated respectfully and left cleaner than they found it."

"We had received a quote from a different big name company for $2000 MORE than what Hot Water Heater Company quoted. Hot Water Heater Company sent their technician, Matt. He came out, gave us a price, went and got the equipment, and installed it - all within less than 4 hours. Great price, great service...and we have hot water!!"
