Default tank less gas hot water heater

Going need a new gas hot water heater soon. Please give me your opinion on a tankless model if you have one.
Thanks

We have had ours for about 4 years and I can run the dishwasher, washing machine and shower at the same time without a loss of hot water. It takes about 1 minute, maybe less to heat in the shower. Needless to say, I love it.

At our current home (not in The Villages) we have a Navien model NPE-240 with a recirculation function. It's nice to have hot water throughout the house without waiting. Two things it required when we installed it was a larger gas meter because it's rated at 199,000 BTU's and needed to tap into a pipe at the end of the system to provide a return for recirculation.

When we build our Villages house we are going to see if we can upgrade to something that we can recirculate the hot water.

Works great, but takes a minute or two to get hot water to the far reaches of the house. They are quiet and our gas bill is reasonable.

So you think it is worth the substantially higher price for the unit.

No. My house came with one installed. If I had a choice, I would have a conventional water heater. The big drawback to the tankless is they are installed on the outside wall and are ugly.

If you currently have a tank type water heater, I would replace it with the same type. A tankless unit will cost more money to buy and to install. You may need to modify your gas service and possibly your electrical service. Also, if the tankless water heater breaks down, how long will you be without hot water if the technician needs to order a part? A tank type water heater can usually be replaced within a day or less by almost any plumber. I don't think the advantages will be worth the cost, if there are any measurable advantages.

Price both types out for the size you need. To replace the size we had, after rebates the tankless was cheaper. Mike Scott plumbing installed ours. Fills our enormous double tub without running out of water.

No it's not with it economically speaking. It's common knowledge to the industry that the payback period for the extra upfront costs and annual maintenance (yes) takes 12-20 years.

The new standard tanks are very efficient. A water heater blanket isn't even recommended anymore. It just isn't worth it. Unless you have a specific need or desire for a space savings or on demand hot water (on demand even sounds "entitled" doesn't it?) there is little reason to get caught up in the hype 😜

If TECO is your provider check with them as they occasionally have a deal on installation and will spread the costs out without interest included in your monthly bill.

Default Rheem Tankless

They are more expensive to buy. They are more expensive to install. They are all 199,000 BTU. You are supposed to descale them every year. Plumber charges about $150 because you are supposed to let the vinegar circulate for one hour. I bought the supplies on Amazon for about $100. Your gas line has to be big enough to support your gas appliances and the hot water heater. If you have a regular hot water heater I would replace it with the same type. New construction is different.

Why would you want to heat water all day long in a 40 gallon tank?When you can just heat what you need.

Interesting. I never heard of a tankless system with recirculation.

Tankless heaters are sensitive to minerals in water and tend to clog,
Faster than conventional types.
If you don’t have a water softener system. I suggest against one.
