What is Tankless Water Heater?

The temperature is adjusted according to the tap setting. It is a great alternative to the conventional heater especially in terms of energy efficiency because the unit does not have to be turned on at all time.

You might need to upgrade your pipes, lines, and gas meter to ensure that. This step will require hefty amount of money, depending on how many upgrades you need to do.
