your asking the wrong question, you should ask (what is the most efficient WH for me?) Boilers are good if you use boiler heat or steam generation for another building service, gas is very quick to heat and has a good price point if gas is in your area, electric is ubiquitous and of electric models hybrid is more efficient. tank-less heaters are good for second story installs and use less overall electricity if demand is low because they are not maintaining temperature in a large tank however tank-less electric heaters also require more electric usage at the instance of heating because it has a very short time to heat the demand water, they also scale/build deposits very quickly without routine maintenance.
Sorry Gabriel, perhaps confusing. a better explanation can be found here - www.ecohome.net/guide/heat-pump-water-heaters-work-one but to try to elaborate (and I hope I do better), There is no 'net addition' of cold added to the house, it is taking some of the heat and condensing it, so it 'feels' colder in the mechanical room but the heating system compensates for that, but that process is more efficient than were it to heat the water like a traditional water heater. In summer it feels like it 'adds cold' because it is removing heat from the air to generate the hot water, so it ends up acting in the same way as an air conditioner. Better? I can already hear engineers cringing at that explanation, and rightly so, but its a hard thing to explain so I'm taking liberties. Best regards.
I still don't understand. You're taking heat from the household air and transferring (exchanging it for cold?) it into the cold water. You then take that heated hot water and using it, with most of the heat going down the waste drain. Logically you are ending up with a net loss of heat from the household air.
not typically, if the duct work becomes too restrictive (plumbed too far) it can reduce efficiency, best to keep ducting very short if you do move air from one place to another using the forced air supply from the cold side...just my 2c
My water heater is,,, in the basement.. colder all year long . How does that factor in?? Also, the hot water heat pump need a secondary drain line, from condensation... and third, these don't have Inlet and outlet on the top. This really screwed us up, they are on the side... So plumbing the lines could mess you up..
This type of unit is better served to be in a warm environment, consider the south a better place for use. up north i would think gas heat would be best. It will cool the space, i have not seen any BTU estimates but whatever heat it puts into the water has to come out of the air the heat pump is exposed to. This unit would be much less efficient in a COLD space and would move into resistance (aka typical electric) heating much more often, thus negating the savings of a hybrid unit.
I don't understand how you can have it both ways. On the one hand, you say that the cold it produces when heating water in winter doesn't make the house colder, yet tout it as cheap air conditioning in summer. Would you mind clarifying that.
Simply put, in heat pump mode heat is removed from the surrounding air thereby cooling it and then expelling the colder air. When in heat pump mode, it is providing as much cooling to the air as it is heating the water by transferring the heat. The video creator does not seem to understand the refrigeration cycle. My unit has the option to switch to standard resistive type electric heating which can be beneficial if the ambient air temperature is very low
I thought the same thing. I think what he's saying is that since he uses a heat pump to heat the house that is 300% efficient then the heat going into the water heater is essentially 300% efficient. The heat pump water heater is only as efficient as the system that has to replace the displaced heat.
Ha - Never really noticed until you pointed it out and you're right, they're all over the place! This dork is not a trained actor, sorry, just doing my best to pass on information. I hope there was some informational value to at least compensate for the pain of having to watch my hands move so much :)
i warranty 10 AO Smith water heaters to 1 Rheem water heaters
Thank you for this video!
"low-flow showerheads" [shudder emoji]. Still a great video. Thanks for the explanation.
How much dose it take to run that heat Pump it is the most stupid thing I heard. I would recommend a tankless with an hydronic tank it is the best

which is more efficient a heat pump, a boiler, or a tankless water heater ?
your asking the wrong question, you should ask (what is the most efficient WH for me?) Boilers are good if you use boiler heat or steam generation for another building service, gas is very quick to heat and has a good price point if gas is in your area, electric is ubiquitous and of electric models hybrid is more efficient. tank-less heaters are good for second story installs and use less overall electricity if demand is low because they are not maintaining temperature in a large tank however tank-less electric heaters also require more electric usage at the instance of heating because it has a very short time to heat the demand water, they also scale/build deposits very quickly without routine maintenance.
Were the ducts installed/connected to commercial LEED standard requirements?
How do I change the default mode from hybrid to electric.
at 1:32 he says it doesn't put cold air into the room, then at 2:32 he says the unit becomes an air conditioner for your home. I am confused.

b.s. If you put this into a heated room, you are doing it wrong.

You then take that heated hot water and using it, with most of the heat going down the waste drain. Logically you are ending up with a net loss of heat from the household air.
Could the left over cold be introduced to HVAC ducts directly above the water heater?
On my hybrid unit it can be

Capture the condensate water in buckets and do your laundry with it.

Irreplaceable in the south, and could probably be made diy with a buried loop underground.

I'd like to hear how that works also.
There is a reply below that attempts to explain this.

pls concentrate thanks
Can this dork speak without moving his hands all around? Don't need the drama.
