A reliable supply of hot water is an essential part of modern homes. An average household may need hot water multiple times a day for cooking, cleaning, and bathing. The most recent models of water heaters have features that improve energy efficiency and convenience. Here is a breakdown of components you’ll find in a water heater.
The Common Types of Water Heaters
The tank-type water heater has traditionally been more common in households than the more recent on-demand systems. They usually have a storage tank with 2 or 3 inches of insulation to prevent heat losses. Typically, they can hold between 30 and 50 gallons of water at a time.
The advantage of tank systems is that they are less expensive to acquire and are easy to install. They have a less complex mechanism, which reduces repair and maintenance costs. On the other hand, you have to wait for the system to heat water. They consume more energy per unit of work and take up a larger space in your interior.
The benefit of an on-demand heater is that it can provide water whenever you need it. For homes that require less than 41 gallons of hot water a day, on-demand systems can yield between 24% and 34% in energy savings. Tankless systems have a compact design that allows them to fit in tight spaces.
The drawbacks of an on-demand water heater include a higher cost of installation. They can also fail to produce sufficient hot water when multiple fixtures are running. Therefore, it is critical to assess your home’s hot water needs before you decide to install a tankless system.
