Many years before we bought our old house, idiots installed the hot water tank a LONG way from our kitchen and bathrooms. (Over 80' of 3/4" pipe) (I think they did this to save money running the gas line to the water heater!) So, it takes 3 minutes at full flow to get hot water to the bathroom.
I
want an in-line, electric water temp booster that connects under the sink and brings the water temp up to a thermostat controlled temp immediately. I'd settle for 80 degrees, but I would like 100 degrees. As soon as the water in the hot water pipe is appropriately hot, heating is no longer required and the booster shuts off.
I picture a unit with a copper coil and heating element that a do-it-yourselfer could install, plugging into a GFI.
Should cost somewhere around $50 - $125.

A good gas fired one is over $1000. |

Well, since these are priced in Singapore Dollars (S$), current rate approx. 1.78 S$/US$, they run $112 - $168, plus shipping... not too bad! Although I need less through-put to wash my face or hands - perhaps there is a smaller model out there?
Thanks! |

That plumber got you, too, eh? |

I've been kicking around an idea for my similar situation: a hot water return line, with check valve, to the water heater tank. A small electric pump cycles the water in the hot supply loop. Shouldn't take much force, as the pressure is equal on both ends. Saves the water; doesn't do much for the time. |

I think these do indeed exist in the form of "flash heaters". Basically, the water is heated as it passes through a series of pipes that are blasted with natural gas flames. The box itself is about 3 feet square and maybe 6 inches thick. you can get about 100? to 120? in the 5-8 seconds it takes for water to flow through it. |

about 6.5 kilojoules of energy. Not at all unbelievable. |
