Otherwise, it will not burn the gas or consume electricity all the time as like traditional water heaters. Moreover, tankless is 24 -35% more efficient than the tank type. If it is energy start than energy factor will be 95 out of 100, means it uses 95% fuel during burning and wastes only 5%. Second or third generation tankless water heaters are using burned gasses for re-generating heat by the condensation process. In this way, tankless save energy and saving the environment.
- Standby Loss: As like in the storage type there is no scope for deposit standing water in the continuous water heater, so there is no chance of standby heat loss. It occurs due to temperature decreases by the surrounding environment of tank body and pipes.
- Long Lasting and Reliable: A tankless water heater is lasting more than 20 years which is two times than the traditional one. So you have to less worry about replacing your heater frequently. Chances of build up rust in the tankless are very less as like the tank types, makes it reliable.

- Inconsistent Temperature: If your tankless having no electronic control unit (ECU), then you have to deprive of getting consistent hot water flow. The ECU is modulating the gas flow to supply consistent temperature in case of variable water flow.
- BTU requirement: To run a tankless water heater required 200,000 BTU propane or natural gas to heat the water. In case of low pressure tankless will not provide optimum output. So, before chose tankless you have to check gas pressure by a professional plumber.
