As a plumber I’m not a fan of heat pumps. They are expensive and complicated. A standard electric HW system is simple and easy to repair. Add the Catch Power unit and you have the best of both worlds. We have an EV and charge it for 6c/kwh from midnight which is hard to beat. Even a solar PV system would struggle to keep up unless it’s a massive 3 phase system. Good video but I’m not sold on heat pumps ✌️
Very good question and great answer 😊. Greetings from Finland just so that you guys understand that you are being subscribed to globally, not only in Australia.
Thanks Jake and Dan for the explanation. Much appreciated. Here in Melbourne it was mandatory to install solar hot water system aling wirh gas ducted heating system with new builds in the last 10 years. Only the new estate's dont have gas connection to the property. I have seen numerous roofs with new solar panels around this solo solar hot water panel and it looks odd. Anyways will have to wait for it to run its life and then get it off the roof. Thanks again for the heat pump option👍🙌
I'm off grid and it is quite cheap to heat water with excess PV if you understand the technology. I designed a PV diverter to resistive heater that will only take the excess, be it 5W or 1KW, and puts that into heating water. It detects when array voltage exceeds the exceeds expected value and diverts only enough energy to bring that voltage back to Vmp. I didn't install any extra panels and it works fine in parallel with any MPPT charge controller. It costs less than $50US to build. I have a very minimal system and I can make enough hot water that my clothes washer uses hot water for every cycle. Amazing that everyone isn't doing this with units that China could easily produce. Solar people are just too technically challenged to understand this technology.
I had a heat pump and the compressor blew up. As is was only 3 years old we converted it to an element. Then the coil leaked the refrigerant in the tank which is carcinogenic was in the tank, please be aware oil floats on top of the water we had probably consumed some of it over the years. We only discovered it as brown stuff was coming out the taps years later. So they can be a health hazard.
I've had this question on my mind for so long. And this is one the most comprehensive explanations I've come across so far. I really appreciate it!

Your welcome Ben! Thanks for your question glad it helped!

Great answer, "Keep it out of landfill". Replace it when it's due.
Good info.
Recovery time is only quick in heat pump systems because of the traditional electric booster element!!!!
With a PW 3 do you still need a catch power for your dumb electric hot water system ?
You've talked about anything but what I wanted to know. Plain old hot water run by solar power. FULL STOP!
