Water Heaters questions, answered by experts

If your system is not vented properly, you could experience what’s called backdrafting. Backdrafting is when your ventilation system isn’t working as it should, and instead of releasing gases outside, they get trapped inside your home.

Gas and propane water heaters create a few types of combustion gases, but the most dangerous is carbon monoxide. If there’s too much build-up of these gases inside your home, it can lead to carbon monoxide poisoning.

Standard electric water heaters (about 40 gallons) typically need a 30-amp circuit breaker. But if you have a newer model, a tankless water heater, or one that’s more energy efficient, you’ll likely need a higher amperage to power it.

Having the right size circuit breaker for your water heater is an important part of making sure it heats water efficiently and runs safely. A licensed electrician can help you navigate your options, and determine what you need for your new water heater.

Unless you have previous plumbing experience or extensive experience with water heaters, you should avoid replacing your electric water heater yourself. This process involves disconnecting wiring and parts from the old water heater and reinstalling them onto the new one, among other difficult tasks. This job is best left to the pros to make sure that everything is connected correctly to avoid serious leaks or malfunctions.

The time it takes to replace a water heater depends on the complexity of the job. Expect your contractor to spend:

One to three hours on a standard tank-style water heater replacement
Two to three hours on a tankless water heater replacement
Four to six hours replacing a tank-style water heater with a tankless water heater
One hour for each additional parallel or point-of-use water heater

Your project will take longer if you’re switching fuel sources, upgrading to tankless, or relocating your water heater.

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.
