It is the energy factor (EF) rating that is used to measure the energy efficiency of a specific water heater. The more EF factor rating your tankless heater has, the better the unit is. Usually, Energy Star certifies the energy factor of the unit.
Warranty: If a manufacturing company provides warranty for a certain time frame, it means that they care for you and your problem with the tankless water heater. Most of the manufacturer wants that you use the service of a professional technician when installing their product. If you follow their rules, usually they help you with a warranty that covers the heat exchanger, parts and labor also. Most of the time the manufacturers provide you with 10 to 15 years warranty period for the heat exchanger. When it comes to parts, you may get a warranty period of 2 to 5 years. And, in terms of labor, most of the manufacturers cover a warranty of 1 year.
The Right Size: Choosing the right size is very important when it comes to buying a propane tankless water heater. First of all, you need to determine the total amount of water your family needs as per the family size and use of hot water. Most of the tankless water heater may supply a flow rate of 2 to 6 gallons if run with gas. If you can determine the flow rate and temperature rise, you can move to see which of the tankless water heater can satisfy your need.
Venting System: Proper venting is one of the most essential things that you should ensure before installing your propane tankless water heater.

Yet, it is always better to take advice from your technician to understand which would be the best place to set your water heater.

Fuel Supply Line: To get instant hot water, fuel supply line contributes the most. If it is not sized as necessary, your burner will not work its best. If your burner uses propane, it can output up to 200,000 BTU/hour. This is really greater than the traditional supply. However, make sure that you have got a gas fuel line that is long enough to help your tankless water heater work quick.
Ignition System: When it comes to the ignition system, there are 3 types of it. If your ignition type is complex it means that it will be way more expensive than that of the simple one. But, on the contrary, a simple ignition system will cost you more energy. Standing pilot light system is less expensive, but costs very high energy. Direct ignition system works either will electrical hook-up or without it. And, hydro-power ignition system work without any battery or electric connection. However, most of the tankless water heater uses a direct ignition system, which you can also choose to use.
