3 Disadvantages of Owning a Natural Gas Tankless Water Heater 3 Disadvantages of Owning a Natural Gas Tankless Water Heater

A natural gas tankless water heater can provide instant hot water and replace your own water heater. However, before you buy one, there are a few drawbacks that you should consider.

Venting

A natural gas tankless water heater needs special venting. Not only is that going to bump up the cost significantly, it’s going to make your home into a construction site. Under code, you need to have stainless steel category III venting for this type of water heater. If you have Type B accessories for venting, those will need to be replaced to bring you up to code. Don’t assume that the venting kit on the water heater will fill your needs.

Gas Line

Will your gas line and your gas connection be ample for a natural gas tankless water heater? It’s possible that your new heater could require more gas than your old unit, and possibly more than your line can handle. You will need to check this first.

Electricity

Although the water heater is natural gas, some do require an electrical connection. Before buying, check on this to be sure you have access to an outlet close to the water heater.
