"I had a great experience with Mitko professional service for our water heater burner problem, I called a day before, and Mitko came to our house next day, he did full analysis & testing of the water heater and right after he did find out the problem and had all required parts in his company van, took him to replace and fixed within couple of hours. Excellent service with reasonable service fee!"

"I got home from work and discovered that my water heater had a major leak that required shutting off the water to the house. Carl at Cali Water Heater responded immediately and less than 24 hours later I had a new water heater installed, water restored, and all at a fair price. Highly recommend!"

"Ed was prompt and fair. He came and installed the water heater the same day I called him. He stayed out that night until almost 11 and replaced our water heater. When the city came came and noticed something else needed to be completed in order to pass, he came out at no cost and made sure the job was done. I would highly recommend Ed and use him in the future."

Water Heaters FAQs, answered by experts

No. Expansion tanks must be installed on the supply side (where heated water flows out) of the boiler. There’s also a list of other requirements for most boilers, including being above the pressure relief valves, being on the inner side of any circulator, and more. Your installation manual should have more information on expansion tank installation requirements and what sort of tank the system is made for.

You should replace your gas water heater when it’s reached the end of its lifespan, which is a maximum of 12 years in most cases. If your unit is over a decade old and showing signs of inefficiency, leaks, or frequent malfunctions, it may be time to replace your water heater. Research how to best maintain your gas water heater to help extend its lifespan.

The standard copper wire gauge to use with any 30-amp circuit is a 10-gauge wire. The National Electric Code specifies a 10-gauge wire with appliances like water heaters running on 30 amps. If you try to use a smaller gauge wire, such as a 12 gauge, with a 30-amp breaker, you run the risk of the wire overheating and melting or causing a fire. Because of the safety hazards, the gauge of the wire is not an area to try to cut costs when connecting a 30-amp breaker to a water heater.

Choosing between an electric water heater vs. a gas water heater comes down to personal preference. Overall, electric heaters are more energy efficient than their gas competitors. They’re also quieter to operate, take up less room, and don’t come with a risk of gas leaks. 

The downside is that electric water heaters cost more to operate than gas. They might also struggle to heat water fast enough for households that use large amounts of hot water. Lastly, a power outage could cause your electric water heater to stop working, whereas gas water heaters may still function.

You have more options for water heaters than ever before. The best one for your home depends on your hot water usage and budget. Some of the more common types of water heaters are the conventional gas heater, a heat pump water heater, or a tankless heater for smaller homes or those with less water demands. Some uncommon types are solar and point-of-use systems. Some homes may have a combination of two units, such as a large heat pump heater and a backup point-of-use system.
