The 40 gallon and 50 gallon gas and electric water heaters are the most common hot water tanks that we install for residential use.

Our experts can guide you through the manufacturer’s sizing charts to help you select which size will be best for your needs.

There are also a variety of sizes available for commercial use. Each commercial application is different so call our experts to schedule a free estimate, which will determine the commercial tank best suited for your business or multi-unit needs.


The capacity of a hot water heater should be based on the number of occupants and the peak hour water demand, regardless of the size of the house. The water heater should provide enough hot water at the busiest time of the day. Also consider the number of plumbing fixtures you have in the home. The more sinks you have, the greater the demand for hot water. Also consider extraordinary hot water demands, such as hot tubs.

The ability of a water heater to meet peak demands for hot water is indicated by its "first hour rating." Read more on for further information. This rating accounts for the effects of tank size and the speed by which cold water is heated.

1 to 3 (or 4) 40 Gallon
4 - 6 50 gallon or 50 gallon high recovery
6 to 8 50 gallon high recovery or 75 gallon
This is only a guide and does not guarantee that you will not run out of hot water.


The most economical water heater replacement will use the same source of energy for your water heater. If you have an electric water heater, replace it with an electric water heater; if you have a gas-fired water heater, replace it with a gas-fired water heater. Changing energy sources will usually require additional plumbing and/or electrical work. GAS WATER HEATERS – All gas water heaters remove carbon monoxide through a metal flue pipe or plastic pipe. Standard gas water heaters vent into a chimney, double-lined vent, or flue liner. Power vent water heaters vent with a plastic pipe directly to the outside. The power vents house a motor on top of the tank to assist with venting. If you need assistance determining which type of gas water heater you have, our experts at Mr. Waterheater are happy to assist you.

Best Outdoor Natural Gas Tankless Water Heater? | Yahoo Answers

I have installed 10-20 Rinnai tankless heaters and two of them outside. I recommend putting the small electrical circuit on a backup battery or generator so that if you lose power during cold months the small amount of pipes won't freeze outside.
They work very well, and ive never had a problem with any of the ones Ive installed.
