Looks an excellent set up, and way to go for the future, especially with the boiler upgrade scheme, but the outdoor tap and supply cut-off do look a bit close. Thanks for sharing.

Thank you :)

Interesting video, you should post your open energy monitor link in the video description for people to check out the performance 👍

[@Wawyed]

Added links in description. Still trying to figure out the most optimal way to charge the Sunamp. I knew before hand it wasn't going to be the most performant with a heatpump cause of the higher temperatures required to fully charge it (65C). Although it's very efficient at maintaining the heat compared to a water tank so it might balance out

[@danpye1991]

@@Wawyed Running at 65c is obviously not ideal for COP. My heatpump uses around 1.5kw to heat a 250litre tank to 45c from cold during the warmer temperatures we have currently. It will be interesting to see what you're using for 300litres worth at 65c.

[@Wawyed]

@@danpye1991 Just to clarify, it doesn't constantly run at 65C just at the end of the charging cycle to fully charge it. How much heat is outputting from those 1.5kw? I want to also understand if I can charge it to maybe 75% and improve the COP.

[@danpye1991]

@@Wawyed So on a really good cycle I used 1.248kwh electricity and produced 6.293kw of heat. COP of 5 for hot water generation but only to 45c.

Great video

[@Wawyed]

Thank you, I appreciate it

[@robandrews9826]

Did you manage to get the sunamp through the boiler upgrade scheme? This is the kind of setup I am after

[@Wawyed]

@@robandrews9826 yes I did 😊

Can you do more content on the Sunamp Thermino, there is very little in the way of customer reviews on how they perform. I would be very interested in knowing things like the flow rate, once drawn from does the remaining stored heat just remain undiluted unlike a DHW cylinder where the cold topping up reduces the whole cylinder's water temperature, do you find you need to re energise daily or can you leave it longer? Thanks

[@Wawyed]

If with flow rate you mean the hot water pressure is the same as mains pressure. That is correct in terms of the stored heat, it releases a constant hot water temperature until is empty controlled by a thermostatic valve (I have it setup to 45C). The heat loss on it is great so it can last for days if its not being used.

[@ianed0007]

How long have you been living with it, I'm guessing 3-4 month since your original video on your set up? I love a bath, I presume it more than capable of filling a bath? The other thing I thought you might have said was it looks too start recharging if it goes below 80% capacity, is this fixed or a level to user can set or just choose to fill once a day?

[@Wawyed]

@@ianed0007 I've only had it for a month. As I mentioned is equivalent to a 300L tank at 40C. So that should be more than enough for several baths. There a bigger size one as well for even more capacity. About the 80% is more like it tells the heatpump that the hot water needs to be heated again but you can control via schedule or manually when you want to do so.

[@ianed0007]

Thanks. I'll subscribe and see if you've got more to say about it the longer you have experience of it. As I say, there is very little of reviews of the Sunamp by real users. I've been interested in one for a while but holding off waiting for more information on hold people are finding them. The low SCoP because of the higher recharge temperature isn't something I had really thought of before, so thanks for highlighting that.

[@Wawyed]

@@ianed0007 I'll like to see after having a full year how much it affects SCOP value. Obviously the central heating won't be affected by it and the hot water is a very small amount of usage compare to central heating.

[@Glenbow1970]

I am just about to get the same heat pump and Sunamp installed in a month or so, slightly bigger heat pump at 16kW version, would like to see how you have integrated it in to Home Assistant.

[@Wawyed]

I've used the Smartthings API with the samsung wifi module you can install with the heatpump. I might make a video explaining a bit more

[@gopikrishnayogarajah]

hey will you be sharing the link to your openenergymonitor ... keen to see the R290 unit characteristics

[@Wawyed]

Sure heatpumpmonitor.org/system/view?id=250

[@ibleedswede]

That outdoor plug is installed too close with regard ignition risks for r290.

[@nocomment8273]

Lol. While most people have a 11 kg propane gas container for camping or the grill at home.

[@garry6909]

So the heat pump and the Sunamp is all there is? No hot water tank? I don’t have space for a hot water tank. The set up you showed in your video would be perfect for me. I too already have the solar and batteries Thanks

[@Wawyed]

That's right. The sunamp is an alternative of the hot water tank

[@garry6909]

Perfect news to my ears 👍

[@normanboyes4983]

Is there not a circulating pump inside the Samsung 7 unit outside, if so why the additional circulating pump inside?

[@Wawyed]

@@normanboyes4983 no there isn't. The Samsung heatpump controls that external pump

[@garry6909]

Hi, your heat pump is a 5kW. Can you say how many rooms / radiators your heating with it? I ask because I just had a quote for a heat pump to install on my EPC ‘A’ rated 2 bedroom , 6 radiator well insulated semi detached house and he wanted to sell me a 10kw system for £18k. I mentioned you had a 5kW system and another channel I watch has another 5kW system. He said it wouldn’t be powerful enough. Needless to say I didn’t buy
