"Just Rite Heating & Cooling installed our central air conditioner today. The team of five were on time, courteous, friendly and hard workers. They laid down runners to keep the interior of my house clean. The boss, Eric, explained how each part of the system components worked. Together we worked out the placement of the ceiling registers in each room. After the system was completely installed I was instructed on the how the new thermostat controlled both the old heating system and the new air conditioning system. Best of all the installation was completed in one day!"

Water Heaters FAQs, answered by experts

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.

No, you’ll need to drain the tank before changing a water heater element, as the water heater element sticks through the side of the tank and uses a gasket to prevent water from pouring out. However, you don’t always need to drain it completely. If you’re only replacing the upper heating element, you can drain the tank until the water line is below the element. If you’re replacing the lower element, you’ll need to drain the whole thing.

Not all types of water heaters require a venting system. Electric tankless water heaters don’t use natural or propane gas, so no venting is required. Instead, they use electric burners to heat water quickly and efficiently. However, any system that does use gas or propane will require ventilation.

Traditional gas or electric water heaters last an average of six to 11 years. However, with excellent maintenance, they can last up to 15 years. Heat pump water heaters, on the other hand, last an average of between 12 and 15 years and potentially longer with proper maintenance. In both cases, your home's water quality can be a determining factor regarding the lifespan of your water heater.

The size needed for your expansion tank is determined by the size of your home's water heater. Expansion tanks are available in 2-gallon and 4.5-gallon sizes. A 2-gallon tank will be appropriate for water heaters up to 50 gallons. An adequately sized tank should have a volume that equals 2% to 5% of the water volume within the system. A plumber can evaluate your home's water pressure, water heater size, and other factors to provide suggestions for picking out the best expansion tank.
