On demand tankless water heater
I am researching getting one of these but not sure if it is feasible.
I read that the new washing machines pulse and cause the water heater to try to cycle too fast and don't warm the water, sounds strange but I understand, and there should be no need for an added tank to fix this issue, maybe a small expansion tank of sorts. Has anyone heard of this?
I was looking at Rheem, they have 2 models a 9.5 gpm and a 8.4 gpm. The bigger is $500 more. I have 4 people, 2 baths, the normal dishwasher, washing machine and not usually running 2 showers at a time but does happen. Also a large bathtub jaccuzi that does not get used enough.

I now have 2 water heaters 40 gallon gas in series and never run out of hot water. One has developed a leak so I shut that one down and turned up the heat a little on the remaining one. 11 years on 9 year heaters so it's time to swap out or go with more efficiency.
I like the idea of direct venting because that can eliminate a chimney that is only used now for the water heaters.
Anyone familiar with these?
I found one that has a recirculating pump of some kind http://us.navien.com/Product/Categor...age1/Details/9
this might work

Just lost my electric tank heater, remembered this thread, any feedback on which way you went and whether you regret it?
Probably going to get a tankless LP model, unless I’m convinced otherwise.

I ended up with a 50 gallon power vent model instead if the instant type water heater for a couple reasons and so far I am happy with that thanks to Bob 5/0.

You could also consider a heatpump hot water heater. If your electric rates are favorable and you run a dehumidifier in your basement they can be cost effective. Likely if you have natural gas it may not work out financially.

Viewers of Fox News, the televised arm of the GOP, scored at the bottom of 30 popular news sources. In fact, the survey found that viewers of Fox were less informed than people who followed no news at all.

Ended up going with a propane fired 50 gallon tank. New well pressure tank and heater are in now and water is back to flowing through the house

Cool
I ended up waffling procrastinating a couple months last spring and then my luck ran out and the other water heater let go all at once, had to drain it down and scramble to get a new one before the end of the week, but we got it done in a few days thanks to Bob.

As with anything, I wish I hadn’t waited so I could have done things on my terms, not based on the needs and preferences of the most responsive plumber.
I suppose all’s well that ends well
