Whether building a new home, remodeling an older home planning your current and future needs can help you pick the right size electric water heater so you don’t have to suffer cold showers.
An electric water heater is basically a storage tank into which cold water flows. There is a switch, which shuts off the flow of water when it gets full. Most electric water heaters have two electric elements, which heat the water and keep it hot until it’s used and replaced by colder water. Each element is controlled by thermostats.
While an electric water heater can be as small as six gallons or as large as 120 gallons, the average family can generally be served with a 52-gallon electric water heater. However, the larger the family, the more capacity will be needed. When planning your needs you should also plan for potential growth of your family as well as the frequency of visitors, which may increase your need for additional hot water.
An electric water heater offers several advantages over gas, for example, as not having to be vented and it can be installed closer to walls and they do not have a pilot light which requires a small open flame or a thermocouple to keep the pilot light burning, which generally needs replaced every year or so. There is also less chance of overheating.
Adjust Temperature To Your Choosing
Another feature of an electric water heater, like most others, is the ability to adjust the temperature of the water through the use of a thermostat. By raising, or lowering, the water’s temperature, it can be adjusted to the family’s liking.
Electric water heaters also have built-in protection for pressure build-up in the form of a pressure relief valve. Occasionally pressure may build up and if it reaches a point higher than the check valve on the water line, it could push the hot water back into the feed line. This pressure release valve will harmlessly release any over pressure. However, having a leak from the pressure valve may be an indication of some other problem, which needs attention.
While maintenance on an electric water heater is minimal, problems can arise and unless the homeowner is experienced in plumbing and electrical repairs, it may be best to leave any repair or replacement to professionals. This could lessen the time needed to male repairs, or replace the unit, ensuring you have the hot water when it’s needed.
