Tankless water heaters heat up water at once without a bulky tank to store water. For that reason, they avoid the standby heat losses linked with storage water heaters. When a hot water tap is twisted on, cold water moves all the way through the pipes into the unit. In an electric models an electric element heats the water. In a gas-fired models a gas burner heats the water. As a result, tankless water heaters give a constant quantity of hot water. You don't have to to delay for a storage tank to fill up with enough hot water.

Several smaller units cannot produce enough hot water for simultaneous purposes in large families.

For residential usage, this will most probably be the max quantity of showers taken at the same time, multiplied by the rate of flow from the showerheads. When this max rate of flow is computed you will then know what sized tankless to purchase.
Although gas tankless water heaters are clearly more efficient than their storage tank cousins, their efficiency normally tops out at 80-85%. Even while gas is a more reasonably priced fuel than electrical energy per BTU of yield power, this is more often than not outweighed by the extra efficiency of the electrical tankless water heater. On top of that, electrical tankless water heaters cost less than most tankless gas units. Furthermore, gas costs rise and fall further than electrical energy costs and generally economists concur that gas costs are anticipated to go up significantly in coming years whereas in most regions, electrical energy costs ought be rather unvarying.
