Tankless domestic h/w

john_58

I have a new high eff laundry machine on the second floor of a big old house. The hot water just never gets there and there is no basin nearby (to run first). Therefore no hot water comes for a hot load of laundry. Is there a plug-in 120v in-line electric tankless heater I can install to remedy this? It would only serve this appliance? What ampereage is req'd? Thanks!

yes John point of use water heaters are available. Insinkerator and several others make them.

John,

my wife and I have not done a "hot" water wash in many years. It would be less expensive to just use cold water with the appropriate detergent.

one way..

would be to put in a small 115 volt tank-type heater. Supply it from the hot line. To size it, run water from the hot hook-up in back of the washing machine into a bucket. For each gallon you get, figure 2-3 gallons for your heater size. So if you get two gallons of cold water before it warms, put in a six gallon heater. Installing a low wattage, 115 volt heater will save you running a new circuit. A Metlund recirc system would probably work too.

Hope that helps.

If Possible



Install a hot water return.. Just a 3/8" PEX line would do it.. But the trick would be to get it down to the water heater.. Pex would "snake" pretty well..

Anyway... Good luck!

Small electric

How many loads of clothes do you do in a row? If the answer is one and you have 8 hours or so between them then a small under counter type tank in series with your hot water line would give you enough for a load of clothes. Buy a 240volt one as they are more common and hook it to 120V, stated wattage will be 1/4 so will heat slower but use a 15 amp 120 circuit. If you think running hot water first will work there must be a standpipe for the washer drain, just tee into the hot supply and into the standpipe to establish flow. If your water is really soft the instantaneous elect may be the way to go but they lime up really quickly where I live and cost alot more than a little elect. As the other post suggested a pex or soft copper recircuit line could probably be snaked down the plumbing stack chase to your basement heater.

Besides electric point-of-use-heat,

You could also consider some of the recirculating retrofit systems out there like the RedyTemp System or the Metlund System, among others.

Wow, Thanks to everyone. There are some great ideas here. Never thought of a recirc line. That might be an idea. We do have hard water even with a softner. You can see it all around the fixtures. Any heater would have a short life. Thanks again.
