Stay far away from electric tankless.

Everyone I've talked to about the tankless says it's worth it. I never asked if they were gas or electric. Supposedly, they're pretty pricey either way to buy and install.

Sorry, no recent advice. We've had a gas water heater for 35 years (not the same one / house). The only one that gave us problems was the "zero clearance" from the mid-90s that exhausted thru the sill instead of a gravity vent.

It seems like tankless heaters have gone down in price since the last time I looked. Why would I want to avoid them? Why would they cost more to install? The weight issue alone seems to make it easier. Isn't it basically the same hook-ups? Power, in and out water pipes? I'm not trying to be a smart*****, I haven't dealt with this in 40 years.

You really have to be careful sizing an electric tankless. To accommodate a 2 bath house, most recommend at least 300 amp service into the house.

@kraziebill : It's a trailer with two old people.
I guess I should be a little more clear. We live in a trailer. In our retirement years, we wanted a place to live that didn't require the same amount of upkeep/investment as a regular home. Think of it as an old car. We just want something that will last as long as we do. It affords us the opportunity do to the things we like to do while we're still here.

I've heard the same as kraziebill regarding the requirement for a lot of amperage to heat water sufficiently in the short amount of time it has to do so.

Now I'm confused. When you said you lived in a trailer I assumed a mobile home. Then you mentioned old car and not I'm thinking it could be an RV? Although you wouldn't be in the market for a tankless water heater in an RV I guess.

@skutfarcus : A 32 KW electric TWH will draw 133 amps on full fire. By contrast your tank type heater is probably 4.5 KW drawing 18 amps.32 KW will get you around 3 gpm @ 70 degree rise. They only get smaller from there.The ONLY benefit to an ELECTRIC tankless water heater is saving room. Period.

@AngryCodger : Trailers, manufactured homes, mobile homes, rvs and cars all depreciate. If I put a top of the line heater in my "mobile home" the value of it doesn't go up. I'm really sorry I even asked this question.
