Although tankless water heaters and solar water heaters are gaining traction in the US, the conventional water heater in Walnut Creek remains the most popular methods to heat water for the home. This article will tell you a bit about how they work, what to look for when selecting one and a few tips on safety.

How they work:

conventional water heater Walnut Creek is available in different capacities. Depending on the number of people in the home and the number of appliances that uses hot water, a system with a tank between 20 gallons and 80 gallons can be purchased and installed. Regardless of the tank capacity they all work the same, cold water goes in the tank from the bottom, it is heated and hot water is taken from the tank top when there is a call for it. As the hot water is drawn off, cold water once again enters the tank at the bottom, making sure the tank is always full.

Conventional tank type water heaters use multiple fuel sources; electricity, natural gas, propane and fuel oil are the most common.

As water is kept hot in the tank at all times, the conventional system is not energy efficient. Even though there is no demand for hot water, as it cools naturally in the tank, the thermostat senses this, and engages the heating element to bring the temperature back to the setting the homeowner wants. This is referred to as standby heat loss and can add up to a significant energy penalty over a year. The only water heaters that do not have this problem are the tankless heaters where the water is not pre-heated but is heated on the spot, on demand. Although the tank on the conventional water heater in Walnut Creek is well insulated, standby heat loss still occurs.

Selecting the storage water heater:

Purchasing the least expensive model will usually turn out to be most expensive in the long run, however, purchasing one which is obviously oversized can result in excessive heat loss and it too will be a poor investment. Prior to purchasing your water heater take into account the capacity and first hour rating, the fuel type and its availability and the energy efficiency of the unit.
