Electric Tankless Water Heaters
About two years ago I purchased a 4unit apartment building in Houston.
Each unit has 1 bathroom and a kitchen, no dishwashers or w/d, each with it's own water heater in the kitchen (a real eyesore). I'd like to replace the conventional electric water heaters with tankless models to conserve space and improve the appearance. Has anybody had any experience with these units? I know that the current circuits will need to be upgraded from 30amp to at least 50amp. Other than that, is the installation pretty much plug-and-play? Is there any radiant heat generated from the operation of the units? Do they make any noise while operating? |

About every other month, someone posts here thinking that this wonderful new hot water system they dicovered called tankless is going to save them a bunch of money every month. This is the first time someone actually has a good reason! Has anybody had any experience with these units? I know that the current circuits will need to be upgraded from 30amp to at least 50amp.

State Industries has done a good whitepaper on tankless considerations, including power requirements and installation. http://www.stateind.com/new/Tankless_WhitePaper.pdf |

Assuming the tankless heater is from a reputable manufacturer and is installed properly, it should work fine under most conditions. There are some corner conditions (like very low flow) where they may or may not work so well. The issue is whether or not it is cheaper to use tankless over a storage tank. While tankless can be less expensive to run in some situations, the overall cost when you look at acquisition, installation, operation and replacement is at best equal and in many cases more than would be for a storeage tank system. That said, there are a few situations (like retrofit, vacation home, unusual architecture) where you might be willing to pay the extra cost to solve a specific problem. |

If your planning on staying with electric power to have a tankless set up, you in for a surprize here. Your going to need about a 125 amp to 200 amp electric service to keep a steady good temperature of hot water to a shower and a kitchen. You might in some cases need a add a 200 amp new meter pan up grade or add a 200 amp meter pan and electric service. It's not just plug and play. You might look at natural gas hot water system and is easily set up with just running a 1/2" natural gas line to it and can be put in a inside wall or closet or on a outside wall. it would 1/3 the cost for heating water and digital controlled of the temperature of the water from 90ºF to 160ºF and supply about 9 GPM depending on the temp.
