The Standard Tank-Type Hot Water Heater
Hot water heaters have changed a lot recently. The hot water heater we install today is nothing like it was even 10 years ago. Many regulation changes and improvements have taken place. Even though standard water heaters still use steel tanks heated by a burner at at the bottom, they now have better insulation, heat traps, and more efficient burners. While these improvements have had very little impact on price, they have improved standard water heater energy efficiency by 8%. There are many fuel choices for tank-type water heaters: natural gas, propane, fuel oil, and electric models are all available. Tanks come in sizes ranging from 20 to 80 gallons.
As of April 2015, new Federal regulations regarding water heater efficiency went into effect. One way that these regulations affect you is that any new hot water heater that you can buy is now required to have more internal insulation, which increases the overall diameter of the tank. That means that if need to replace your old tank-type water heater you can no longer do so in the same amount of space. If your space is tight, you may want to consider a tankless water heater.
An 8% energy efficiency improvement is not much compared to what you can save with heat pump water heaters or tankless water heaters, but standard tank-type water heaters have been around the longest, have the lowest installation cost, and are the most familiar, which are the main reasons for their continued popularity. If you choose to install a conventional water heater, something you can do to make it more efficient is to insulate the water pipes coming into and out of the tank. Such an easy thing can make a difference in the amount of energy and money you save.
Of course, everyone wants to make their water heater last as long as possible. Since the average life span of a tank-type water heater is only 8-10 years, one of the best things you can do to make your water heater last longer is flush it on a yearly basis. If you are not ready to replace your water heater yet, we offer all types of repairs and maintenance. We can insulate older models to save you money, flush your tank, and check the anode rods and other internal workings to make sure that they will last as long as possible.
