Whether it's Rinnai, Navien, Takagi, Noritz, Bosch, AO Smith or ant other tankless water heaters they all have some misconceptions. The misconceptions are as follows:
"Instant hot water". While the hot water is instantly created it is not instantly DELIVERED. The only way to speed up the delivery time of a water heater is with a pump. Not all tankless water heaters are capable of having a pump so careful consideration in the model you choose is needed.
"An electric tankless can easily replace my electric conventional tank water heater." This is not the case. Your current electric water heater has 220-240 volts serving it. A good tankless electric water heater needs the equivalent power as 3-4 central air conditioners. That means (3) 50 amp breakers with (3) large wires must be added to accommodate the electric tankless water heater.
"Tankless water heaters are expensive." While the initial costs of install a tankless water heater may be much more than a standard replacement tank style you must consider the monthly cost savings of having a water heater that only uses energy when it is in use. A conventional tank style water heater heats up and cools down 24/7 costing you money every time it does.
We hope this helps and you will consider Avery & Sons Plumbing + Tankless when deciding if a tankless water heater is right for you.
