In large sizes of tankless water heaters, the UEF factor stays between .7 to .8. Some companies manufacture large-sized water heaters having 90% efficiency, but they are expensive.

For small spaces, mainly mini tankless water heaters are preferred because they are easy to access. Look at your space and needs before making a choice.
The lifespan of a tankless water heater depends on how you use it and its quality. Some companies manufacture amazing water heaters that work fine without any failure for a long time. But you need to take care of it on your own too. Tankless water heaters of good quality requirements to be flushed once a year. It is advised to use water softeners, which prevents any clogging. On the other hand, if you buy a cheap quality tankless water heater, you will need to flush it a lot as the scale deposits build up. So, it is better to buy the best tankless water heater that will have a long span and work without any problem.
Installing a tankless water heater seems no easy step, but it is an important one. Every house has a different piping system, and there are specific water heaters for a different type of piping. Some piping systems may prevent you from installing the water heater indoor, and in some cases, it can be the opposite. So, buy a tankless water heater that suits your piping system to avoid any difficulties.
Venting is a necessary step for tankless water heaters. In the process of heating water, unwanted gases can be produced which are not good for health and getting rid of them through venting is required.

Natural Gas or Electrical:
The tankless water heater has only two energy sources, i.e., either natural gas or electricity. Electric water heaters are more common because almost everywhere in the world electricity doesn’t go out that much. Moreover, if electricity is cheaper in some places, people will prefer electric water heaters. But not every place has the same facilities. Load shedding is a common problem in some parts of the world, especially Asia. People there prefer natural gas tankless water heaters as the connection of gas to a house is very common. If you are thinking about buying one, have a look at these factors before making a choice.

Only a few companies have accomplished this objective to some extent. Their water heaters can heat water with great accuracy with an error of a degree or two. It is better to buy one with great accuracy as other water heaters will cause a lot of trouble by fluctuating between temperature ranges.

Whereas on the other hand, a cheap one can heat the water quickly.
