“Have been successfully using Chaves my Buderus Gas Heating System for over 10 years. Chaves technicians have bee experienced, professionals and very prompt. Recently have been having a lost of hot water in shower issues with my Rinnai Tankless Hot Water Heater. Problem usually triggers a Rinnai code 10 air supply or exhaust blockage. Over the past 5-10 years I have had numerous non Chaves vendor service calls to solve the problem with limited success. What usually happens is fix provides shower hot water but any attempt for taking a grandchildren baths constantly results in lost of hot water with tub 1/2 full. Based on long success with Chaves I called to see if they could solve by Rinnai lost of top water issue. Chaves sent (think Dwayne) 14 year experienced technician professional, knowledgeable, an efficient have noticed improvement both in hot water flow and retention.”
