Delay in getting hot water to kitchen faucet

jimbo_7

I remember reading that there was a load-based dodad that augmented the water temp until the DHW was able to deliver to loads on the other side of a home. Something that plugs into a GFCI under the sink, essentially. Anyone ever hear of this? Think is was also mentioned on Ask This Old House. Thanks in advance...

Delay in getting hot water to kitchen faucet

Here's the problem. In colder weather there is a significant time delay, and waste of water, getting hot water from the kitchen faucet. Water heater is on other side of house, approx. 50+' away, lines run in unheated crawl space. What is best way to approach solving problem.

hot water delay

you need a recirculation line between the water heater and the faucet and a bronze circulater

Insulation and heat trace

Another solution is for a heat trace line on the hot water supply pipe, along with good pipe insulation. I like the Ray-Chem HWAT product for hot water temperature maintenance, self-regulating with an optional controller to only turn it on when the ambient temperature goes below a setpoint. Low wattage, and doesn't draw a lot of juice.

I am using this more and more, rather than recirc pipes on commercial buildings, as the low flow faucets take too long to get hot water using conventional DHW recirc design. So I'm heat tracing the hot water legs down to within 3 feet of the taps to insure hot water reaches the faucet in under 10 seconds.

try this

Hello: Have a look at www.gothotwater.com for their d'mand system. It will likely fill your need and be inexpensive to operate. Of course, I'd insulate all the hot pipe you can get to with thick walled foam.
