My husband and I would like to install a tankless hot water heater in our home, but we are concerned that it may affect our high efficiency washing machine (LG WM2016C). The washing machine takes in water in short spurts, and we're wondering if the tankless hot water heater will not be able to heat water up fast enough.
Does anyone have any experience with this problem? Any recommendations?
I like our tankless and do see the energy savings but have to admit they are not machine friendly.
Where are you located Chuck and what kind of water temperatures do you see over the winter?
I should also add, the problem with our tankless is the plumber installed it in the opposite end of the crawl space. Opposite all facets, opposite anything that uses hot water and opposite any logic now that I see how it works. If I had of knew then what I know now...

You had a PLUMBER install it and he moved it AWAY from the major points of use? Quel fou! The best location for tankless heaters is CLOSE to the usage points, in fact the ability to move them to where the water is needed is really the major selling point for installing them.
So I guess I should say to the OP, a tankless might work great for your washer if the distance from the heater to the washer is short. In my case, I have a Paloma 7.4 Series tankless heater which takes approx 6 seconds from the time you turn on a facet before it is kicking out hot water. Then you have to consider the flow rate multiplied by the distance from the heater to the washer to get an idea of how much cold water has to be purged from the pipes before you get any hot water.
It may work well if you can get the tankless heater within a few feet of the machine.
I'm in Wisconsin & have an electric t/l water heater!
We buy tide cold water soap!
Wash everything with cold water & works great!
If we do need hot water, well then just run hot water for a bit to get all the hot water lines nice & hot. We never have a problem doing this either when needed.
