They are larger than the point of use tankless heater and can handle a large on demand hot water requirement.
You will be able to run the kitchen sink, 2 showers or more and the hot water faucet in your bathroom all at the same time with a whole house tankless heater.
The point of use water heater is installed just before the outlet and you will require a lot of them to cover the entire house versus just purchasing a whole house water heater that meets the needs of your hot water demands.
With the usual water heater, you may have experienced running out of water every now and then or when somebody is using the shower.
They work very well for residential use.
You will save a lot of electricity as none of the water is stored like the conventional kind.
In the conventional kind of hot water heater, a tank full of water is heated at once and stored, a lot of which is not used.
With the whole house heaters, standby heat loss doesn't take place, considerably reducing your energy bills.
Depending on how much water you will need and how many showers will run at a time, you should choose a whole house tankless heater of the right capacity.
A lot of factors need to be considered while choosing the unit.
You will have to study the temperature of the incoming water and the desired temperature at the outlet.
The water is heated when it passes through a series of electric coils or in some cases gas burners.
They come in a lot of different sizes and can be run by electricity, propane or gas.
As some of these required venting, new designs allow them to be installed outside the house to eliminate the venting requirement.
