  1. And all I wanted to ask is "Does anyone have a Samsung ASHP?" 🤣🤣
  2. The Energy Performance Certificate A99 rating was issued in November last year with all the additions we have done, adding insulation (as part of the refurb), ASHP, solar thermal and PV . The figures I have there are for 2018, the last full year I could make a comparison as the house has totally changed since then. £180/yr FIT for PV min estimate as I'm still awaiting payment, they had a problem with a line diagram and didn't contact me. £428/yr RHI for ST minimum estimate as they haven't paid me yet due to a mix up in MCS. The initial setup was self installed but when they installed the HP they added the 58mm tubes and tank and comissioned it as a new installation which in effect it was. £886/yr RHI for ASHP I don't think you "have" to go on to the Agile export tariff. From what I read it was brought in to give those who had no access to FIT i.e had installed PV after the cutoff date of April last year some reward for exported electicity. As far as I'm concerned I stay on the FIT agreement I have with SSE. We will be using as much as we can for battery charging and car charging. But it doesn't really matter as FIT pays you whether you use it or export it. Of course the profit is not actually profit per say, it covers the EST 0% loan we took out to install the ASHP. I can't calculate things on a like for like basis as the house has changed so much and the money we have spent on the house will probably take 10 plus years to recover especially given the global rescession after the COVID19 outbreak has settled. Each sub- project was costed and should begin payback after approx 5yrs Batteries (after they're all connected) 3yrs ST, 7 yrs ASHP, and 11 yrs PV (although the 1st year has outperformed the projected generation figures by 18%) I keep my cars for about 20 years so if the Tesla lasts that long at 4p per mile and 200 000 miles ish I think that will pay for its self as well. But in the end they are all worthwhile as I will be using less energy that I was 2 years ago and doing my bit to save the planet and that is the most important thing to me. Wow this is some welcome thread!!
  3. The Tesla display gives me readout when I charge at 5a that equates to 1kWh and when I up that to 6a it changes to 2kWh. If I'm reading it properly I put the solar thermal in myself about 7 years ago. it cost just about £900 including new 150 lit tank it was initially a Navitron 20 tube 42mm system.. worked fairly well in the summer . the hot water fed into the cold water of the combi boiler and so pe heated the water for the boiler all year.. even by a couple of degres in the winter. I gradually added bits i.e 10 Navitron 58mm tubes then another 10 and when we had the roof done last year I switched the 48mm tubes for a 58mm system. The new system which has been up and running for about 9 months is a 40 tube Navitron, (well 38 complete tubes as I managed to break the seal on two getting them on the roof but they're still working just not as efficiently as the others) into a 200 lit double insulated copper tank which is connected to the 210 lit as a pre heat so that if the water temp goes over 70c it diverts to heating the secondary tank. That lot cost about £1200 to fit and I managed a lot of it. ST works much better than PV I've found you seem to get more "bang for your buck" Servicing? There is none for the ST the PV I think is about £135/yr pls mileage.. but since they're coming back to connect the batteries...
  4. When its all up and running.. a good bit. 2018 the last complete year no solar no batteries just 15 tubes for solar water heating. Gas 14178 kWh costing £ 400 approx Elec 3851kWh costing £532 £932 total 2021 expected with everything running properly smart meter, batteries and car 8000 miles per year 70% charging at home Gas 15kWh costing £65 approx Elec 6500 costing £440 @ 6p overnight or solar charging £505 total minus RHI/FIT £1494 Profit £989 or over £82 pm Of course this is just guess work.. but I have figures for the house going back 10 years when the kids were still at home so its an educated guess.
  5. I'm Lucky in having solar thermal for 80% of our hot water needs.. It only really needs an assist in the 4 winter months and even then only a couple of times a week.. now the kids have gone and of course the obligatory 60C legionaires once a week. I've got 40 Navitron 58mm tubes heating 350 lit in 2 tanks. Its a little overkil for the summer but it means in the winter we can last a little longer without the HP. We're planning, once we get the smart meter, on charging the batteries, car and using the HP at night. I'm paying 15p per kWhour on the green fixed tariff at the moment so being able to run everything at about 6p is a massive saving for us despite the addition of the car. But having all the batteries online will mean that we use them in the expensive periods during the day and so should see an H24 rate of about 5-7p. I'm using an Ohme smart charger, again waiting for the smart meter to use it in anger, but still trickle charging off the excess solar at 6ah, 2kWh I just monitor the sunshine and stop it if it gets cloudy. and if I ever get to do a journey over 10 miles!! I'll use the local free charger in town although I'll sit and watch a movie for the time it takes !! at 20kWh I can't seem to get the 50 kWh ones to work with the Tesla. Thats an interesting graph Mr Magic. You really can see where the windy days and the poor solar generation are interesting to see just how little coal generaton there is.
  6. Shortly I hope, I'll be on the Octopus Agile tariff which is based on the wholesale grid price. A no brainer for those with batteries. https://www.energy-stats.uk/octopus-agile/ Although you could use my referral code instead 🙂
  7. That I don't know I'm afraid. I don't think so, but I havent't gone that deep into it. In fact yes it does! It allows you to download the raw data to the cloud in .csv and .xls format
  8. The graphs are for the past 2 days, I find that the most useful, however I can display from an hour to years.
  9. Here's a few views for you As you can see they're quite detailed.. You will notice the SOC graph isn't correct. We surmise thats because there's no BMS on the system.. there will be one when the new batteries get connected and possibly the Greenrock EMS next year
  10. Yes, I can monitor via the VRM portal.. monitoring a bit more at the moment (the plans have gone awry with the virus changes.. 7KWh less as the new batteries aren't connected, no smart meter so I can't get on to the Octopus Agile Tariff and the arrival of the EV) as I'm trying to balance trickle charging the car and washing machine/dishwasher plus the recharge of the batteries from the solar during the day (not all at once obviously) Fortunately in the East of Scotland we get a good amount of sunshine, as long as the wind stays westerly. I also have a daily and monthly Excel worksheet moitoring useage and production and cost. I've often had the "we need to increase your DD" email and gone back to them chalenging their figures and they've backed down 🙂
  11. They're Aquion S-line batteries. specifically the Aspen 48S 2.2 KWh. not the smallest (935H x 330W x 310D) or the lightest at 118kg but when they're depleted you can tale them to the local tip as they're only plastic and aluminium. They take no looking after, just make sure they dont get too cold, no lower than -5c and you can use the full capacity, unlike the other types of battery which can only use a percentage of their capacity. Unfortunately, they're no longer available new under the Aquion brand as Aquion in the US went bust due to cashflow problems. (you may be able to pick up one or two secondhand) Blue Sky in Austria bought the rights and now produce an amazing range of batteries, BMS and EMS. Check out their YouTube channel. You can find them for sale in the UK but I don't think they have a UK dealer yet. I have 2 new, well one year old now, and I managed to pick up 3 others from Kent in December which will give me 11KWh and I'm awaiting their connection.. but now that might be a while.

  12. "I suspect the internal thermometer (2) is reading low. Can you see where it actually is and get your thermometer in EXACTLY the same place? " No Sorry Dave the internal no.2 is surrounded by very tight foam insulation with only the tip of the sensor, where the sensor wire joins, protruding. "But irrespective of that, there must be a parameter that lets you set the target temperature higher than 45 degrees " I've been through the ( very complicated) manual. I can't see anything that can get me any more heat. I think that No.2 is giving false readings to the HP controller leading it to believe that it is at a higher temp. I'm surprised there's no others here with Samsung experience I was led to believe it was quite a popular HP.
  13. Thats just it Dave .. It won't go any hotter. Thats the max I can get out of it. When the OAT goes down the temp stays the same and from all the graphs I can see the water temp should increase up to about 50c at about -10c OAT but it just stays at 44C. That in its self we could live with but its the 6c temp drop (on weather correction) from HP sensor 2 to sensors 3 & 4 that's troubling as te max temp we can get into the house is 38C.
  14. 🙂 Correct 4.4Kwh. well spotted. I think they're geat.. they need no looking after and no BMS just deplete and charge. I will be installing a BMS when I get the other 3 connected.. but that's going to be a while away. I'm also considering the Blue Sky Greenrock EMS when they get a UK dealer. Sounds wonderful and Welcome to THE forum. Thanks Mike
  15. Brae? Just been chatting to a Telsa model 3 owner from Brae on another forum 🙂
