Questions & Answers

if the power goes out, will the tank still produce hot water

if the power goes out, will the tank still produce hot water
Asked by: Pez
My heater is fired by natural gas. There is no connection to the electrical power. Hence, the answer to your question is "yes" it will produce hot water during a loss of electrical power.
Answered by: Ozzie
Date published: 2019-07-15

is the drain metal or plastic?

Asked by: len
I'm not where the heater is, but memory says it was metal. I bought it in early 2017, so it would be best to ask the manufacturer what the current situation is. 866-279-4566. These valves usually screw into the tanks, so you could change it if necessary. My heater was made in Mexico.

Can I replace a 40 gal 40000 BTU gas water heater with a 50 gal 34000 - 38000 gas water heater?

Asked by: Marv
It should. make sure you replace it with the same height and you have a little space left to right to fit it in, They are sold as Short or Tall, so the same height makes it much easier. but as far as the gas hook up, they are all a standard height off the ground and swap off is simple. gas load is less

Performance Platinum 40 Gal. Short 12 Year 38,000 BTU Natural Gas Tank Water Heater is rated 4.6 out of 5 by 666.
Rated 5 out of 5 by from Rheem Performance Platinum 40-gal Short Water Heater This water heater came fully assembled in the box, and was less than a week from manufacture date. With the higher efficiency, the unit is about 2 inches taller than the circa 2000 versions. Unfortunately, that meant a re-design of the copper tube inlet and outlet runs. I know that lead solder is banned to reduce net exposure, but the alternate solder materials are way more finicky to get a good seal. I now have the situation such that the next unit can grow another 2 inches (about max before it bumps attic rafters in the above laundry room install location). I used flex copper fittings (15", 18", 24") to connect to cold, thermal overflow, and hot tubes. I used flex stainless for the gas connection. The start-up matched to the instructions, as the first time to light does take longer that expected. The unit includes a piezoelectric spark generator (good bye to matches!!) The unit controller also includes a blinking LED to indicate an active pilot. The unit does not require an electrical connection. The heat settings do not match the specs, as they are a couple of degrees cooler. Thus, I had to use the B setting to get water sufficiently hot at the kitchen sink/dishwasher.

The old one was a Rheem as well 10+ years old, when the new one installed, I got warmer water than the previous one. 10+ years was 50 gallons, I changed this with 40 gallons. This is sufficient for 2-3 people family.
