Can you switch to a tankless water heater from a heater with a tank?

• <div><p>Yes, you can replace a current tank water heater with a tankless model or vice versa. If you’re maintaining the same fuel source—gas or electricity—the switchover should be smooth. A conventional tank requires open floor space, while a tankless model can be wall-mounted. If you’re switching to a tank water heater, you might need to clear space for it. Gas-powered tankless water heaters need a large volume of gas when they start running to heat the water instantly. You might need to increase the size of the gas line when going from a tank to a tankless model.</p></div>

Why is there no hot water in my shower?

• <div><p>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 <a href="https://www.angi.com/articles/shower-water-cold-but-sink-hot.htm">shower not getting hot water</a>, 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.</p></div>

What happens if a water heater is not vented properly?

• <div><p>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. </p><p>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.</p></div>

• <div><p>Signs that your water heater needs replacing include rust or corrosion on the tank, persistent leaks, inconsistent heating, strange noises coming from the heater, decreased efficiency, and visible damage.

However, in some cases, these issues can be fixed with a repair rather than a replacement, so make sure to consult a pro before investing in a new water heater.</p></div>

• <div><p>Signs your water heater is about to fail include: a unit older than ten years, rust water coming from your faucets, banging and rumbling noises when you call for hot water, and leaks coming from the tank.
