Conventional Storage Water Heaters
Storage water heaters are the large, familiar white tall, cylindrical tanks. There are natural gas, electricity, propane heaters for you to choose from and they store from 20 to 120 gallons of water, depending on the size of the tank.
If you are looking for a conventional water heater, your first decision will be whether to buy an electric or a gas hot water heater.
Electric hot water heaters tend to have higher EF than gas units one. But though electric units may use their fuel more efficiently, electricity is a much more expensive water-heating fuel than gas in most regions.
Alternatively, you can combine an indirect water heater with a higher efficiency boiler. For an indirect water heater, you will need a separate storage tank. This combination will give you the cheapest way of heating water and help you save money, especially during the winter months. Portable water heaters are good choices for adding hot water to outbuildings, shops, or garages.
