Hi my name is alex,I want to replace my tank water heater because is under my AC unit and the AC filter is right above the water heater and that is the only air return I have .I guess they did it wrong when the put the system in ,so the AC filter is collecting all kind of stuff and I can't cleane it properly because of the tank water heater.I have the option of going tankless water heater and enclose the air return and move the tank less water heater to the other side of the wall(laundry)My question is does tankless waterheater really works ?I have two bath.Thank you guys this is my first time asking.thanks again.I "m planning to buy the electric tankless water heater (TITAN).thanks for the input folks.

What is more cost effective electric tankless water heater or regular electric tank heater and does it mater the amount of consumption through out the day i.e. number of times hot water is used throughout the day?

Iv'e installed tankless water heaters and have nothing but the nicest things to say about them. True they cost from $500 for a three element to $600 for a top of the line four element. But consider, they will last 30 to 40 years compared to 8 or 9 of a regular heater. Expect a savings of 40 to 60% on your electric water heater bill.(Figure the savings over the years plus the replacement cost of heaters and it begains to pay for itself.) This unit will not leak or rupture and stays 99.5% efficient through out its lifespan.
