Water heaters have been rated some of the most essential, yet highest energy-consuming appliances in many premises. The efficiency of a water heater, consumed fuel, and function should, therefore, comprise key aspects to be considered during any water heater shopping activity. Well-chosen water heaters guarantee a steady flow of hot water, whenever needed, as well as saved energy costs.
Factors to consider when purchasing a water heater
Extent of function
A water heater’s service is a key factor to be considered when water heater shopping as the hot water needs of a person/ people determine the appropriate water heater system to be purchased and installed. Some water heaters can only deliver hot water from particular points/ faucets (Point of Use) whereas others can supply hot water throughout a building, simultaneously. Point of Use water heaters, such as shower heads, are most appropriate for small premises with minimal hot water needs, whereas Whole House water heater systems are appropriate for large facilities with numerous, simultaneous hot water needs.
The cost of various fuels that power water heaters always impact water heater shopping decisions. Aggregate fuel costs usually comprise the cost of purchasing the specific-fuelled water heater, the installation and maintenance cost of that water heater system, as well as the cost-per-unit of the consumed fuel. Natural gas, liquid propane and electricity comprise typical water heater powering fuels. Whereas per-unit-cost of gas and liquid propane are small, the acquisition and installation of their powered water heating systems is advanced due to the required plumbing and safety measures. Whereas electric-powered water heaters have the highest efficiency, per-unit-cost of electricity is much higher than that of gas and liquid propane. The installation and maintenance cost of electric-powered water heaters is, however, lower than that of gas and liquid propane. Water heater shoppers should weigh their short and long term finances in regards to whichever fuel-powered heater they purchase.
Water storage capacity
The capacity of a water heater should be directly proportional to the heating needs of a building. Large-tanked water heaters consume excessive energy to heat water that is not entirely needed whereas small-tanked water heaters must overwork to supply premises with adequate hot water. During water heater shopping, people should consider their hot water needs at any given time, and the regularity of their water heater needs. Conventional tanks that keep hot water heated all the time are appropriate for all-time occupied premises whereas tankless water heaters are suitable for one-off hot water needs.
Water heater shopping should be a strategic and informed process rather than a random, cheapest water heater acquisition spree. Water heater shoppers should consider the hot water needs of their building, as well the consumed fuel and efficiency of a water heater. Follow us for more helpful HVAC information.
