Power4Less Integrated Heatpump Geyser

Lupus said:
You'd be surprised on how even that "little" water for washing dishes uses :-(. I normally have the heat pump switch off at 10pm, not cause of usage, but because of noise. It's not too noisy as you said, but mine is in a corner so it can reverb, which I don't want interrupting the neighbours.
But yup, right now you're in the learning phase on where and what to get the best out of it.

Yeah like I said above they actually recommend never turning it off but both for the noise and power usage it didn’t make sense to me and I’m generally far more annoyed by things going on and off than constant noise.

But I’ll certainly give it a try at some point and see.

My concern of it being cold in the morning isn’t so much of a drama, the old geyser was the same after all and colder than this for sure, it’s rather whether it can heat up well enough in the same time because I used to manually override it an hour before I wanted to shower in the mornings.

I’ve set it to 60 now and it’s coming on at 8 and I’m still in bed so we’ll see what the noise is like now.

What's the spec for standing heat loss..? Pretty sure a standard geyser has far less standing heat loss than this..

A standard geyser does have quite a lot less standing loss, that's why I suspect it's more that hot water was used more then thought, cause 10 degree cold water mixing in, even 25l can effect the overall temp.

During the day you could get it to use the 2kw element and at night the 600w? It will take as long as a 2kw element would to warm the water but still use about half the power. So maybe have it run after the 8pm shower to 55 degrees?
From the app you should be able to set timers and such to get it to run at different temps throughout the day, mine from 7:45am will go to 50 degrees, then at 9:30 it will go up to 55 degrees. So maybe look at that as well, play around with the different temps during the day and night. Turning off from 10pm to 7am or something shouldn't cause any issues + it not running at that time is more for noise levels. Yes it's not loud, but it's still a hum that can be annoying at that time.
 
I can of course use the boost function with the 2kW element in a pickle but I’d like that not to become the norm every day.

And besides then it makes more sense to rather have it start at 07:00 than 08:00 if that’s the decider.

Yeah would make sense to potentially run the 2kW element mode during solar hours and during “battery time” just the heat pump.

Without full home assistant integration that’s not happening and right now I only have the temperate setting exposed not the modes.
 
Energy Standing Loss is 1.2kWh/24 Hours which is a value that makes no sense to me.

If the water is at test temperature, air outside at it as well, it will need 1.2kWh to heat back up to temp.

Modern geysers require the standing loss to be low enough that it basically makes no sense to switch them off unless you're gone for a few days. With a heat pump as well, could even be a week.

If the noise annoys you, then sure, keep it off, but usually you'd be asleep early morning and won't hear it, so you'd want it on at that time to heat back up after the night / coldest part of the morning (just before sun comes up).

I've found if the pump is run at 8 to 9pm back to 55. The water at 5am is 52 degrees, if left till 7.45 and no one showers it only really kicks in again at 9 to 55
 
Hi Guys. Many thanks for such a lovely blog on this heat pump conversion. Very detailed and helpful. I am contemplating installing one as soon as mu geyser pops. I would appreciate from the community if there anyone managed to configure their heat pump with Home Assistant apart from the On/Off switch. This would be useful. Thanks

you could just install a heat pump without waiting for the geyser to pop, it will warm the water and keep the geyser.

Well I have good news...
Since I use the official Tuya integration I found this XTend Tuya add-on and it pulls in all the sensors that I found in the app.

Interestingly it also adds from power metrics, but they don't appear to be working just yet so I don't know if that's just a placeholder or if it actually has hidden power consumption options available.

It also has a daily/monthly/yearly consumption that isn't in the app.

I've turned most of them on to see what they do.

I am not quite sure if I had to enable the Beta API in Tuya Cloud Platform to make this work, or if the integration just took a while to sync it back.

Nice bonus to have a real temperature sensor outside I can probably use for other stuff instead of getting it off the internet.

60 feels way too hot for my liking, but interestingly running it for many minutes on end now to make sure I had the right sensor it didn't even fluctuate by a single unit, maybe it takes a while to update that once the cold water hits or it simply starts doing the magic the moment that hot water valve opens.

Yeah I had that notion as well but at 16k excluding installation it didn't seem to really make all that much sense.

Yup but in your case the geyser burst already, so swapping it out made more sense. With installation mine came to 25k
