Question by MG: What are the most eco-friendly methods of heating water in a house?
Our water heater is looking very sad and yesterday our neighbors burst. I took it as a sign.
My husband wants to get a tankless water heating system.
I’m wondering which methods are most eco-friendly, energy saving, etc.
I don’t think we can afford solar panels.
I should have mentioned that I live in South Florida so if I can harness the sun’s energy in a way I can afford (upfront) then I’m in the perfect location to do it.
Feel free to answer in the comment section below

The tankless system would be good because you don’t have a tankful sitting around all the time cooling off and having to be reheated while everyone is asleep or at work. The energy used is essentially consumed right there on the spot.

You may use a hand propelled electric generator. That also keep you healthy.

there are 2 types of solar panels, photovoltaic – that create electricity to use for any purpose (like heating water) and solar thermal – used for collecting heat which is typically used to heat your home, your hot water, or even your pool. The former are typically expensive, the latter can vary a lot in price depending on technology. I wouldn’t dismiss solar thermal collection before exploring it. It is likely more expensive, and certainly more complicated than a standard (and probably tankless) hot water heater too, but remember the difference is paying for the higher cost up front, then getting essentially free energy for years. The cost of energy will likely keep rising over time too, so saving 50% now might cost you a whole lot more over the lifespan of the product you buy.
Depending on your location, a geothermal heat pump system can be much more efficient for heating and cooling your whole house, as well as heating water. Its not worth it for just hot water, but if you are looking at larger solutions these systems get rave reviews. Cost is high, but again you are paying up front and saving in the long run.

If you have natural gas, that seems to be inexpensive compared to oil or electric.
To use electric efficiently (and get ‘free’ air conditioning) you may wish to consider a heat-pump water heater, but expect to pay more for it. Your utility might give you a loan, and you could save money ever after on electric bills, but they are more complicated, and cost more.
GeoThermal is good too.
If you are in a sunny area, you may wish to consider solar.
