Correct me, if I’m wrong.

Trust me, my plan for today is to end this age-old debate on the credibility of a tankless hot water heater.

I know many of the readers of are newbies and first-time buyers so definitely, knowing the pros of a tankless water heater is very important from a buying point of view.

Therefore, on a very basic level, these units can indeed deliver on their promise to supply heating without the inconvenience of bulky storage tanks.

Since they are highly efficient so qualify for the federal tax credits which could be of great help when it comes to offsetting the steep installation cost.

As per my knowledge and experience, the federal government offered a 10 percent tax credit on the overall cost of buying and installing a tankless hot water heater.

Energy star-certified traditional storage heaters also qualify for the same 10 percent tax break which is definitely something that might grab your eyeballs, isn’t it?

The gas tankless heaters are further segregated into propane and natural gas.

So, you can choose the one that caters to your requirement as well as falls well within your budget.

Failing to do so can void your warranty for sure.

So, before buying a tankless water heater make sure that you’re updated with the specifications, terms, and conditions.
