Electric heat pump water heater

Steps:
1. Shut the power off to the electric water heater and shut off the main water supply to the house.
2. Connect a hose to the bottom of the tank and run the hose to outside. Drain the old water heater.
3. Use the pipe cutters to cut the pipes to the water heater and remove it.
4. Put the new heat pump water heater into place.
5. Connect the new water heater to the main water supply using the appropriate size and type of pipes to match the existing water line.
6. Install a vacuum valve near the top of the water heater to prevent the water heater from collapsing in on itself in case it is turned off.
7. Be sure that the water heater has a T&P valve and that it is correctly installed.
8. Some installations may require an expansion valve or expansion tank.
9. Turn the water and the electricity back on.
Resources:
Richard installed the Voltex® Hybrid Electric Heat Pump water heater, manufactured by A.O. Smith (www.hotwater.com/) to save electricity over a conventional tank style water heater.
The other materials used for this project, including PVC piping, PVC glue, pipe cutters, and wrenches can all be found at home centers.
In the workshop, Richard discusses which homeowners should consider a whole-house electric tankless. Expert assistance with this portion was provided by Bosch Thermotechnology (www.bosch-climate.us/).
Expert assistance with this segment was provided by Jim’s Plumbing and Irrigation of Orlando, Florida.

This was an exact replacement for the old one that lasted about 10 years.
I bought this water heater
I have an exact model to replace my old propane water heater. This has paid for it self in the first year I'm using it. Very happy with it. Plenty of hot water for a family of 4, plus keeps my garage cool in the summer.
Every video I watch I learn something new and useful, thanks for what you do.
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!
I've never had a water heater last 20 years. That's amazing his lasted that long.
I’d like to see more of how you installed everything behind the tank
I have a concrete lined (HydraStone) hot water heater that was installed in 1995. It is still working just as well as it did when it was installed. It holds 120 gallons. It is a lot of water, but it's barely on.

Great explanation!
Love it I've never seen that type of water heater in the UK with the heat pump. Great idea p.s I'm s plumber as well
Good education! What psi should be set for the Thermal expansion relief valve that is installed in the cold water line side?
I guess I should add one of those vacuum breaker valves to my HPWH, I was a little surprised to see the CPVC run right to the water heater. O assume that's what the homeowner already had in the area but I thought most water heater installations recommended a flexible line for the final connection, something like a corrugated stainless steel line. That way if there's any kind of seismic activity it's less likely to split a line. I wonder why more of the heat pump water heaters don't have connections for ductwork. I imagine if you were in Florida and it never got really cold and you had a steam and hot attic if you could pull that are down for your intake that would make the unit much more efficient rather than using air from the room that is probably going to be cooler than the rest of the house from the water heater running
How much cold air does this thing actually put out? Is it going to cool down my garage at all? I live in Florida so I really wish it would.
which T&P valve and vacuum valve used? thanks.
Nice video.
In FL, you'd think they'd come up with a way of integrating a HW heater like this into the central AC system. This way it could use the waste heat from the central AC to heat water, and waste cold air coming out of the water heater as part of the AC system.
I just got a Gen5 Rheem Proterra Hybrid water heater and the compressor hum is unbearable (this is a known issue). After there any solution that counteract the harmonics that cause the hum?
Can i use Coleman's English mustard on the pvc or do i have to use oatey's?
Hi. I have a question?How confident are you about electrical water heaters? I have
