Hi dori_m,

What, specifically, are you finding that's confusing???

There is a common misconception that a tankless heater cannot keep up with a high demand of hot water.These (and other heaters) are sized by estimated demand which figures that x number of people will be drawing x gallons of water.Very few ,if any,units will supply enough hot water if a family takes back to back 30 min. showers while washing clothes and running the dishwasher.Before you buy anything,someone should be sizing the unit to your application and they should be able to explain any possible limitations.

There Are several places you can gather information on "tankless" water heaters, both gas and eletric. One at www.seisco.net, and another at www.e-tankless.com.
Good luck

I love my tankless water heater. I intsalled a Takagi TK-1 this summer. I chose the Takagi because I have a large bathtub, and neede denough hot water throughput to fill it. The Takagi has more than met my expectations --- there's always plenty of hot water, and it can operate more than one hot water 'appliance' at a time. Get it, though, with the thermostat control --- the factory-set 140 degree water is too hot for appliances that don't mis hot and cold, like your dishwasher. Be careful about the smaller Aquastar heaters --- they're good, but don't have the same throughput and typically can only operate one hot water appliance at a time. The TK-1 is about $1,100 with thermostat and hanging bracket --- more than a tank type, but supposedly they have a much longer life.

Can anyone tell me if there is a way to get hot water faster from a tankless water heater ? Our new home is about 6000 square feet and we have problems with hot water ... It takes forever to get steaming hot water !!
Any suggestions will be greatly appreciated because we desperately need this thing to be fixed AS SOON AS POSSIBLE !!
