Mine is cooler, it is a single unit that sits outside and heats my water and my house.
Bonus: when someone has a shower in summer and I am sat outside in the garden, I can position myself in front of the fan of the heat pump for a nice cool breeze.
I have a heat pump water heater that’s vented to the outside and I call it my outdoor air conditioner, it’s so nice to stand under the vent on a hot day and get cold AC on my neck.
Kinda curious how much of a difference to efficiency you get with it being vented. Mine has a massive fan and heat sink on it and that sits outside. Surely limits the potential airflow unless you have a 1m wide hole in the side of your house.
I have two 8 inch penetrations that are ducted directly to the water heater, an inlet and exhaust. During summer I imagine I’m getting fantastic efficiency with source air being from outside at 80+ degrees (F). In winter we do have occasional freezing temps but usually above 40ish. I don’t have hard efficiency numbers but I’ve had it for over a year now and have definitely noticed savings on my monthly electric bill.
I should mention the water heater is in a closet, hence why it’s ducted.

Suppose it does depend on what you compare it to, still far more efficient than an overpowered electric kettle.
