Water Heaters questions, answered by experts

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.

Due to the high temperature, using stainless steel vent pipes for your tankless water heater’s exhaust vent is best. Also, it is safe to use a flexible vent duct as the exhaust fan. If installing the exhaust fan yourself, make sure you are using heat-resistant silicon to connect the exhaust vent and the duct on your water heater.

You can and should vent the gas from your hot water heater to the outside of your home. Traditionally, these gases were vented back to other gas appliances, like stoves or furnaces, but many jurisdictions have outlawed this practice due to the risks it provides. 

Most water heaters today use atmospheric venting that exhausts the gas out of the home through a pipe.

There are many issues that can cause cold showers, but the most likely is a problem with your water heater, especially if other fixtures also don’t get hot water. If it’s just your shower not getting hot water, you likely have a broken or damaged shower cartridge. You can replace this yourself or hire a plumber to do the work for you if you’re not comfortable working with plumbing.

Most standard residential water heaters, which are typically around 40 gallons and use 240 volts and between 3,500 and 5,500 watts, require a 30-amp, two-pole circuit breaker. For smaller, point-of-use water heaters using 120 volts and between 1,500 and 3,000 watts, a 30-amp breaker is also often adequate. However, some models may have different needs; units that use more watts than average may require a 40-amp breaker, while smaller units might only need a 20-amp breaker. Newer, tankless, or more energy-efficient models can also require a higher amperage. Having the correct breaker size is crucial for safe and efficient operation, so it's best to consult a licensed electrician to determine the specific needs of your water heater.
