Instant Hot Water Heater Advantages and Disadvantages

bdacottage asked:

hot water take to long to get to the bath faucets.

I am in the process of building a house. I have heard of the On Demand, instant hot water systems. Please let me know if any of you have used them, and if you consider them to be a worthwhile investment. It will be for two people and two small dogs, no kids or extended family. I am hoping it is not only cost effective but energy effective.I am also curious about radiant heating. I am located in North Carolina, so I don’t have the extreme temperature changes of the north.

SAVE WATER! The Hot Water Lobster Instant Hot Water Valve saves, water, time and money. How Long does it take for hot water to get to your faucet or shower? A lot of precious water is wasted down the drain while waiting for hot water. Even worse is the cost to heat the cold replacement water, which enters your house at ground temperature. HOW IT WORKS! When the water in your hot water pipe and the Hot Water Lobster control valve cools below the user adjustable temperature (40-149 degrees F), the thermal materials within the Hot Water Lobster control valve contract, and silently open the valve.
