I don’t blame it, being nearly 20 years old, rusty and neglected. I had been thinking of replacing it with a tank less water heater, but now I had to do the research and get it installed fast. The rest of the family does not care for cold showers.
To install the tank less water heater, the cold water outlet and hot water inlet had to be relocated, gas line rerouted and resized, an electrical outlet installed and a new flue/air vent installed. Monday after work the old water heater was removed, and drywall removed to access the water and gas lines. Tuesday, our neighbor who works for a plumbing company, was able to order all of the necessary parts. I worked thru the plumbing changes on paper and made a parts list, lots of copper fittings, and iron pipe and fittings. Wednesday was spent buying the pipe and fittings. Thursday during lunch I picked up the ordered parts and after work read the installation manuals. Friday was spent preparing for the piping retrofit on Saturday. Saturday the water was turned off, pipes cut, fittings sweat soldered, and outlets temporarily capped for a leak test, no leaks. Then the gas was shut off to reroute and upsize the heater and water heater gas line, again no leaks. A new electrical box was added. Sunday started with the water heater isolation valves being prepared, one successful, one not. Heating the valve the brass housing cracked. Being a specialty valve, none were available locally, so we fabricated a temporary bypass and will replace with a new valve in the near future. Holes were cut thru the stucco wall for the flue/air vent and condensate drain line. Finally, the water heater was mounted on the wall, gas and water connections made, and the control panel connected.
After about 30 minutes double checking the installation and checking all settings, the unit fired up successfully! After a week of cold water we are taking hot showers again!
