Mine just went out a while back and I looked at going tankless. If I remember right, I would have had to run new wire and bump up to a 220, which I decided I didnt want to do. The ones that put out enough water for my familys usage were pretty expensive and required alot of power. Those would be the kinds of things youll want to talk to the fellow at lowes about, or whereever you go.
Go gas, get the one that's 199k BTU and yes it takes power but just a normal 110 outlet... Biggest thing to consider is how much demand is already on the gas system in your house. Often times, you have to devote a line specifically for the tankless because of how much gas they use

The only other gas is the furnace, I will check to see how much it uses versus how much gas supply my house has. Thanks for the info
I have a whole house gas one that is mounted outside. It has been great and will do it again when the time comes. Flushing is not bad, I use a little pump and a 5 gal bucket. The plumber I had install it set it up with flush valves, so 2 washing machine hoses and 4 gal of white vinegar and you are good.

The fellow at Lowes is the last place I’d seek advice about anything.

There are 3 certainties in an uncertain world:

I had one at my previous house. It takes a 1" gas line or greater (depending on the BTU's). You do have to do the annual flushing, which really isn't that difficult. If you have hard water, you need to install a inline water filter, otherwise the heating will result excess mineral buildup in the heat exchanger. Now it is just the wife and I and we have all the hot water we need using a tanked unit. As others have mentioned avoid the electric units, which I would agree with them as well. Pick a central location if possible. Mine was located in the garage and during the winter months it was hard to get hot water to the master bathroom located at the back of the house. I blame the builder because the one he installed was only rated at 120 degrees.
You can have your plumber change your gas system to a 2lb system if the line is not big enough. Also if it's just two of y'all the ones that push 180,000 btu's will be fine. It's all based on ground water temp(rise) and GPM. Navien makes a 210S or A that can handle both bathrooms. I bet you furnace is not more than 100,000 btu's. Navien can be vented with 2inch pvc pipe.
I put in an electric tankless water heater 2 years ago to replace my 50 gal electric water heater that started leaking after 20 years. My house is all electric and I done a lot of research before making the purchase. I didn't want to have to run gas lines and I only had to run wiring about 10'. I got the 27kw unit which is a little oversize for us. We have 3 bathrooms. We can run all 3 showers at the same time in the winter and still have hot water. I tracked my electric bills for the first year and the best I can tell it saved me about $200 for the year. Some of the things I like about it is 1) takes up less space. Only about the size of a breifcase hanging on the wall. 2) Never run out of hot water 3) a little cheaper electric bill. Cons - you have to wait a few seconds longer at the shower in our bath that is the farthest away from the water heater for warm water to start. I did install it myself. It takes 3 breakers for mine but I had plenty of room in my 200amp breaker box.
