The three rules of thumb in purchasing a new water heater are: do not rush, size matters, and efficiency matters. Natural gas prices and electricity prices should be factored into the choice of unit. It has been estimated that between 15 percent and 30 percent of the utility budget goes for heating water.Fuel Sources
Several sources of energy are used across north America to operate home appliances, including the water heater. Fuel oil works with conventional storage tank water heaters and combination space-heating and water-heating systems. Natural gas too is readily available in many areas to accommodate various types of water heating systems.
Solar water heaters require a south-facing roof for exposure, and noted to work best in the southwest part of the United States. A back-up water heater using gas or electricity as its fuel source may be necessary during those times when solar energy availability is limited.
Types Of Water Heaters
Sources agree that when selecting a water heater, consider all appliances, size of household, peak water usage and the environment. Water heater types can be classed as flash or on demand, or tank heaters which use a larger surface area and tank storing a reservoir of water. Depending on fuel source, either an electric or gas element periodically ensures the water heating in the tank to stay adequately warm.
Water heaters using electricity are noted to have a greater tendency to break down, wear out, especially if hard water wears the lining of the heater down. In general, insulating a water heater or reducing its temperature to between 120 and 130 degrees Fahrenheit can help save overall wear and tear.
The Right Type
Sizing the water heater to peak demand of the household is part of the ultimate selection process. Compare the FHR, first hour rating, stated on the water heater’s energy label, with a determined water usage amount during peak household time.
Solar water heaters work best in maximum sun exposure areas. On demand heaters are noted to work well in structures where space is small such as a condo or apartment, They require minimal surface area and can be installed underneath a sink.
Noted drawback is limited use to perhaps showering or laundry, compared to the tank unit capacity. Additionally, on-demand water heaters cost substantially more up front, and savings is realized slow and steady over time.
