Can I Really Save Money By Installing A Renai Tankless Water Heater?

I have a 4,000 sq foot home with 2 25 gallon water heaters that are hooked up in Tandam. When one blew a few years ago the plumber said just do two, so you will have plenty of water. I was thinking about getting rid of both of them and getting a tankless water heater, but I understand that with purchase and installation, it could run $2,000 or more. Is it worth it?

    Although the initial cost is more over the years it will pay for itself. that is if it is gas, electric will cost more over the years.

    They only you get ahead with a tankless water heater is if you don’t use hot water much. The advertisers claim a gas savings of up to70%. Tankless is not more efficient or better. It just does not burn gas to keep water hot in storage.

    I am not a fan of tankless heaters. The initial cost and installation takes a long time to recoup. Many plumbers will install them but not do service work on them. If you have hard water, don’t even consider them.

    If you’re th only one using hot water, I’d say go for it, but since you have a tandem 2-tank system I guess there’s a whole family using hot water and the dishwasher etc. I wouldn’t bother.

    Yes, as long as you don’t need too much hot water at one time you’ll really like the tankless.
