You probably only think about your water heater when there’s a problem, such as only cold water coming out of a faucet. There are four types of them used in homes.

Tank Water Heater

This is the most common type of water heater. It’s a large, round tank of water usually found in a garage or laundry room. Tank water heaters use either electricity or gas to heat the water in the tank.

The tank is insulated, which slows the amount of heat lost. The tank is heated on the bottom and warm water naturally moves to the top. There are electrical elements inside the tank and a pressure-relief valve on the outside in case there’s too much water pressure.

Tankless Water Heater

As the name implies, these water heaters don’t have a tank. Instead, they heat water only when it’s needed. When a hot-water tap is opened, cold water flows into it and it’s heated with electricity or gas. The hot water then flows to the tap. Once you turn off the tap, the tankless water heater shuts down. They are very energy efficient.

Evans Mechanical of Eureka, CA, installs, and repairs water heaters. We sell Noritz brand tankless water heaters because they’ve been making high-quality ones for over 60 years.

Hybrid Water Heater

These water heaters have a tank and an electric heat pump. They use less energy than a traditional water heater, but more than a tankless water heater. They cost about twice as much as a traditional water heater.

Point-of-Use Water Heater

A point-of-use water heater only supplies hot water to one location, such as a faucet or bathtub. They’re useful if you have an addition to your home built and don’t want to run plumbing to it.

Evans Mechanical is a company that offers repairs, replacements, and maintenance for water heaters, furnaces, heat pumps, and air conditioners. We can also help you with your indoor air quality. If you’re looking for an HVAC company you can trust, please call today.

Excellent service from start to finish. Joe came out to give us an estimate on what we would need for a new furnace, never pressured us to buy the top of their line just giving us options on what we would need for our home. Then the date set for installation Thomas and Ryan came out on time and did a great job.

Martin R.

Evans Mechanical is an excellent service committed to customer satisfaction and guaranteed quality workmanship. Our water heater burst and they were very responsive. They sent a technician out the same day and it was determined the heater was beyond repair.
