Water Heater FAQ

If you do not understand how your water heater functions or other details about these unique machines, you are not alone. Water heaters are somewhat complex machines that require ongoing maintenance and eventual repair. Let’s take a look at some of the most frequently asked questions pertaining to water heaters.

How long does it really take for water to heat up?

The length of time it takes for your water heater to heat up hinges on several factors ranging from the make and model to the type, size, etc. In general, if you are waiting longer than usual for water to heat, it is a sign your water heater is not working nearly as efficiently as it should. However, if your water heater system is working as it should and you still aren’t happy with the rate at which it warms water, the addition of a recirculation system will help warm your water that much faster.

Why is my hot water rusty or brown?

If the water warmed in your hot water heater is brown or rusty, it is a sign the water lines have rust. An alteration in water pressure just might loosen up the rust, sending it through the water lines. However, there might also be a break within piping, resulting in dirty water. Furthermore, there is a chance the water heater’s glass lining has been compromised, causing the metal jacket to generate rust. If this is the case, a leak will soon follow so be sure to ask for help right away.

When should water heaters be replaced?

The average water heater lasts around 10 years. If your water heater is at age eight, it is time to start perusing the market for a potential replacement. When in doubt, reach out to our team for a professional consultation. We will analyze your water heater, gauge whether it has a lengthy or short useful life remaining and perform repair or replacement based on this review.

Are there any clues that indicate my water heater is defective?

Yes. If you run out of hot water in a short period of time, if your system’s pilot light does not remain lit or if there is standing water, wet fittings or wet pipes, it is a sign your water heater requires repair or replacement. Furthermore, if it takes longer than usual for your water to warm, it is a clue that the assistance of our water heater specialists will likely be necessary sooner rather than later.

What is the optimal temperature to set my water heater at?

The answer to this question hinges on your preferences as well as those of your family members. In short, a wide range of water heater temperatures will prove acceptable. The average person is content with his or her water heater set at 120⁰F. In fact, this temperature is the pre-setting that manufacturers select for new water heaters.

What does “first hour rating” mean?

First hour rating is a gauge of the amount of hot water that can be produced by the water heater per hour, beginning with a full tank of hot water. As the hot water is used, the water heater warms incoming water at the recovery rate. Electric water heaters recovery rates are typically lower than those of gas water heaters.

Should I put a blanket on or around my water heater?

Some homeowners and even some water installation installers from years ago added blankets to their water heater in an attempt to provide an additional insulation layer that might help the unit retain warmth and operate that much more efficiently. Nowadays, water heater manufacturers are adding such extra insulation directly to the tank so you don’t have to bother wrapping blankets around the unit. In fact, adding blankets to your water heater is a bad idea simply because it is a potential fire hazard.
