Conventional Water Heaters

Conventional tanks come in a few different sizes. Typically, a 40 (151 litres) gallon is recommended for a 1-3 person household and a 50 gallon (189 litres) for 4+ people. In some instances, a 60 gallon may be necessary for larger households.

There are two types of venting for gas water heaters, natural draft and power vented. A natural (direct) draft system uses outside air for combustion. A power vented system uses the internal air for combustion.

On average the life span of a conventional water heater is 10 years. These units do not require maintenance.
