In addition to these two factors, we also consider the following:

1- Price

Don’t purchase the highest quality On Demand Water Heaters if you don’t compare prices.

In determining what kind of price range it would fall into, consider whether or not an item would be useful often. It’s so that we don’t get lured into buying products outside of our comfort zone just because they look cheaper.

8- Specifications

It is possible to get an idea of the power of a product by knowing its specifications.

9- Warranty

Getting a warranty on your product is the last thing you should do. How did this come about? I don’t know what you would do if something went wrong with them or you wanted an exchange. You can check to see if the seller offers returns on incorrect orders as well as faulty products delivered to your house. This ensures that no matter how buyer beware you may feel, there is always a safety net in place just waiting until you need it.
