There many options to choose from when it comes to selecting a new water heater. Economic purchase price, efficiency, and performance, are some of the most prioritized factors when it comes to water heaters. There are still many other unique factors that could make a particular water heater right for you. Below are the points you should consider and the questions you need to ask when choosing the best water heater for your home.
What Are Your Priorities?
The first thing to think about when purchasing a water heater is identifying what is important to you. Do you want your water heater to be efficient and environmentally friendly? Is your family’s comfort and availability of hot water the most important priority? Are lower initial costs or lower running/maintenance costs most important to you? How long do you want your water heater to last? All of these questions help you find your priorities in your choice of a new water heater.
How Much Hot Water Do You Use Each Day?
Choosing the right size and type of water heater relies on evaluating how much hot water you use each day. By taking note of the output of a hot water outlet or appliance, and the time that it is used for each day, you can calculate the approximate volume of hot water used in your home in a day. This number can be useful to inform your hot water needs and also your tank size requirements if you have a solar water heater.
How Much Hot Water Do You Use at the Busiest Time?
The peak hot water usage in your home is important for both choosing the right water heater type, as well as its capacity. Tankless or on-demand water heaters are most recommended nowadays for their greater efficiency, lower running costs, and long lifespan.
However, if you need to use a large volume of hot water at once through several outlets during the peak time of the day, a single tankless system may not be the best choice for you. You will need to choose more than one tankless system installed in parallel, or choose a different water heater such as a conventional tank.
What Energy Sources Are Available to You?
Natural gas is an inexpensive and efficient source of fuel for water heaters, but not every home has a gas supply.
Electricity is widely available, but electric water heaters are less efficient unless you choose a heat pump water heater. You may be limited to just one choice of fuel based on your home or location.
On the other hand, if you already have a heat pump system at home, using this for your hot water supply could make sense. If you live in a cold climate and frequently use your furnace or boiler, it might be most efficient to have a tankless coil or indirect water heater installed.
What Is Your Local Climate Like?
The efficiency and operation of some water heaters depend on the climate. Solar water heaters are best suited to warmer climates that receive plenty of sunlight. Heat pump water heaters work most efficiently in climates between 40-90 degrees Fahrenheit. On the other hand, tankless coil and indirect water heaters are not efficient choices for a warmer climate.
By weighing up your priorities and the needs of your household with the opportunities and resources you have available, you can choose the best water heater for your home.
