Ummm……know what else would save money? Having the right sized water tank! That tank is HUGE! 2-people home only requires like a 40-50 gallon tank. What's that one, at least 100? Total waste of money!
you should kiss that ole AO Smith on the lips…20 years….and she done good. 🙂 LOL
You've lost all your savings if anything happens to the compressor on that thing.
Why aren't there any basements in Florida? Wouldn't you want a basement, and a deep one at that, in a region prone to hurricanes?
Vacuum release valve? Really? The system is pressurized to 30-40 PSI. If you need that valve it is because a big bomb went off nearby or a black hole opened. Both of which if it suck the system from 30-40 PSI to negative pressure that is a problem the least of your problems is the water heater "collapsing."
I am thinking of putting one of these in my garage in NC. In the summer obviously the garage gets hot no issue, but in the winter the garage can get cold – sometimes well below freezing for several nights in a row. What happens in that case, I suppose the backup elements would kick in and heat the water?
He seems to go with this solution a lot. I'm wondering if he'd ever recommend a tankless electric heater solution – e.g. plenty of power and a solar roof.
I am a Canadian homeowner. I watched the above video and realized that there is not benefit to me, in fact, it is a negative benefit, and here is why.
Our building is electrically heated. We are living in an area where the winter temperature drops to -20F overnight, and perhaps to -10F for days, during mid-january to March..
Any heat in the house came from electrical heating, so the heatpump to transfer the room heat to the water tank is obtained from electrical heaters.
Our hot water tanks (60 Gallon size), are very well insulated, and we do install a loop connection to act as a heat-trap. It is done for both the cold and hot water lines.
We could benefit from a dual energy tank for the months of May through mid October. But….
On the negative side of using the above dual energy tank,, our insurance companies will not insure a home for hot water leaks if the tank is more than 10 years old, even though the magnesium rods are replaced every two years. It is a policy common to all the insurers.
We generally get 20 years out of a new glass lined tank. Our newer tank models have three heater elements, with different wattage ratings. For converting to those tanks, the electric company covers about 1/3rd of the purchase price.
By the way, if the top element is heating, the other two are off. When the top of the tank reaches temperature, it enables the middle element, and when the middle of the tank reaches temprature, the lower element is turned on. Each element has a thermostat set for 50C (125F.). A full tank of very cold water can be heated to temperature within three hours.
Bottom line, the above tank in the video, is great for geographic areas where winters are mild and summers are quite hot. Our tanks are located inside a furnace room within the home. A fan and compressor noise is not an issue.
Hot water heat traps are simply a loop of PEX or a flexible loop, between the tank and the home line, preventing convection exchange of heated water up into the house, with the room temperature water. That convection occurs when the taps are all turned off.
Did he say hot water heater? What is that?
I have A.O. Smith water heater that’s 30 years old, replacing this weekend with hybrid. I’m confident it will reduce my electric consumption!
