If your home's hot water tank is failing, it may be time to start thinking about investing in a replacement. You may even have reached out to a plumber already to start exploring your options. When it comes to choosing a new hot water system for your home, you might even be thinking about investing in a tankless water heater instead of the traditional tank system. Here's what you need to know before you do.

Do You Need Hot Water In More Than One Place At A Time?

If you have a busy household and find that you need hot water in multiple places at once, such as doing dishes and laundry at the same time or two people shower simultaneously, you'll want to consider this carefully when you choose your tankless water heater.

Remember that the larger the tankless heater you install, the easier it will be for your water heater system to keep up with the demand for your home. That means that you need to consider your household's typical water heater usage when you're choosing your tankless heating system.

Is There Accessibility For Venting?

Tankless hot water heating systems must be vented because of the combustion air system. That means you need to be able to install your tankless water heater system somewhere that has clear access to run the necessary vent lines. 

You may need to vent the system through the chimney, or it may need to be vented horizontally through the wall. Make sure that you know how your tankless water heater needs to be vented so that you can be sure your installation company takes that into consideration.

Are The Plumbing Lines Sufficient?

Your inbound gas line for the tankless water heater must be a large enough diameter to sustain the demand for your water heater. Your water heater installation technician and your plumber will have to consider the fuel demand for the system and ensure that the lines are large enough for the necessary flow.

In addition, your water inlet must also be large enough to sustain your water heating system. The more water that can flow into your water heater system, the more easily your water heater will be able to keep up with your necessary outbound demand. 

These are a few of the things you need to think about when you're investing in a tankless water heater for your home. Talk with a water heater installation technician near you today for more information.
