Does Rust on a Water Heater Mean It Must Be Replaced?

Monday, October 2nd, 2023

You never want to see rust or other types of corrosion appearing on important metal appliances or fixtures. It’s bad news because corrosion weakens metal and eventually causes it to deteriorate and flake away. 

Because a water heater is a mostly metal device that holds and circulates water, it’s in jeopardy of rusting. Thankfully, water heaters have special defenses built into them to prevent rust and other types of corrosion from getting an early hold on them. These defenses include the sacrificial anode rod that attracts rust to it rather than the tank; the expansion tank that keeps oxygen out of the main tank (corrosion requires oxygen to trigger the chemical reaction between water and metal); and a glass lining inside the tank.

Yet seeing that your water heater has rust on the outside can still happen. When you see rust on your home’s water heater, does this mean the water heater is finished? Is it time to call us for a water heater replacement?

Is Your Water Heater Beyond Repair? Let’s Help You Find Out?

Friday, June 25th, 2021

A water heater is a major purchase to make for a home, and nobody wants to replace their current water heater until they need to. The tricky part is understanding when that “need to” time arrives. We don’t recommend you continue to run and run an older water heater until it fails completely and breaks down. For one, that will leave you unexpectedly trapped without hot water and a longer period to wait until a new one is installed. For another, the dying water heater will waste tremendous amounts of energy as it declines and probably deliver less hot water than it used to.

It’s best to get in front of a water heater replacement by understanding when to have a new system installed rather than continue with water heater repair in Fresno, CA. We can provide you with some important info about when a water heater has gone beyond repair, but please don’t make a decision until you’ve worked with our team—we can help you find out when it’s time for a new water heater.

Old water heater

Even though it is summer and our daytime temperatures are around 100 degrees, running out of hot water because of a water heater malfunction is still something no one wants to deal with. If you’ve had to do a lot of recent repairs on your water heater just to keep it operating, it may be time to consider the purchase of a new one. The good news is that there are several options available for homeowners when it comes to purchasing new water heaters in Fresno, so replacing an old water heater may actually be better for your home. And remember: it’s best to have a professional company like Purl’s Sheet Metal & Air Conditioning install your water heater to ensure that it goes in correctly.

Types of Water Heater Upgrades Available

There are several types of water heaters currently on the market:

Conventional Water Heaters

Conventional water heaters have been the norm for many years, and still remain a very popular choice among homeowners. Conventional water heaters are cylindrical-shaped storage tanks that heat and hold water for usage in your home. These types of water heaters come in different capacity sizes to accommodate a range of properties, holding anywhere from 20 to 80 gallons of water at a time. Different fuel types can heat the water, including electricity, natural gas and oil. While great strides have been made to increase energy efficiency with this type of water heater, it still may not be as energy efficient as others on the market, and the average lifespan is 10 to 12 years.

Tankless water heater

Tankless Water Heaters

Tankless water heaters have become very popular over the last few years, and for some very good reasons. One of the main appeals of tankless water heaters is that they heat water on demand; this means there is an endless supply of hot water for your property. Secondly, as the name indicates, there is no need for a storage tank to hold the hot water. With a tankless system, the hot water is heated directly when the hot water tap is turned on; the cold water is instantly heated by a heating element that uses either natural gas or electricity. This feature makes tankless hot water heaters very energy efficient.

One of the main drawbacks to tankless water heaters is that the flow rate of the water is typically lower than that of a conventional water heater. A second drawback can be the initial cost, but on average, tankless water heaters last longer than conventional ones and they can save money on a monthly basis through utility bills.

Heat Pump Water Heaters

Heat pump technology can be used for a wide range of household appliances, which is one of the reasons we like them so much here at Purl’s Sheet Metal & Air Conditioning. Using the same type of process for heating and cooling your home, a heat pump water heater removes the heat from around its space to heat the water in your home. Storage tanks are used with this system, and can store up to 50 gallons of heated water. Heat pump water heaters are recommended for geographic areas that don’t get colder than 40 degrees, and they require at least 1,000 cubic feet of surrounding air space, (approximately a 10-foot x 10-foot x 10-foot room) for installation.
