I am also on octopus go. Checked again this morning and everything is still the same.

I hope i understand this correctly, forgive me if i am on the wrong track. My octopus in home display will only show zero when there is excess PV. The on line account shows both usage and export amounts daily, weekly and yearly. I hope this helps.

As far as I know the feed in tariff from the suppliers will only work with a smart meter. They need exact readings as the FIT payments are very small compared to the unit rate you pay.

I have gone the same route with heat pump, solar panels and battery storage. Changed the gas stove to induction after using gas for 40 years. Had the gas meter removed and capped to make sure i avoided the daily standing charge which amounted to £92 a year.

I would not know how to work out the COP. I am far too old to have this type of information. Tell me how in simple terms and i will try.

I don`t know how but i have fixed again until 17/02/23. at same rates. Happy days.

I know it is a long time since i posted here, but i now have figures for a full year of running the heat pump. To save you looking back, the house is ex council built in 1937. Double glazed , with cavity and attic insulation no doubt done by the council before being bought by the previous owner. Total of 8 radiators. 2 bedrooms. LG Therma V 7kw mono block. Octopus go at 5p and 12.93p 1082 units @.05 = £54.10 5799 units @ .1293 = £889.71 Daily charge 25p x 365 £91.25 Total for the year = £1035.06 No gas supply since installing heat pump, I don`t have any records of what i was paying for the dual fuel , but it was probably a bit less than this. I have just fitted 16 solar panels with 5.2kw of batteries, so it will be interesting to see the difference in the next year. I hope this is of interest

I do not use cooling, and it is kwh of electricity used for all heating and hot water.

I have a LG 7 kw Therma v. I have had it for just over 1 year. The total kw used from 19th Dec 2020 to 19th Dec 2021 was 4058kw. We use the heating all day in winter as we are retired and like to be warm. I have had no problems with the heat pump and it has just had it`s first service. It has been set at AI +1 and this seems to keep the temperature at 21.5 deg. I occasionally have to change the setting to +2 when it is a bit warmer outside as the temperature for some reason can fall to 19.5 and not come back on. No doubt this is to do with settings which (for me) are very confusing. No problem at all with hot water set for 50 deg. Just watch the size of your hot water cylinder as i only have 150 litre due to available space. Hope this helps.

I toyed last winter with installing a fan assisted hi level heater for our kitchen, as the kitchen was not warm enough and due to wall space available could not fit a bigger radiator. Just before winter i bought a Myson RC 10-6 high level fan convector, and now i am happy with it. As far as noise is concerned, it is acceptable in a kitchen but would not be in a living area. I have set the dip sws so it only operates in the 2 lowest speeds and even in lowest it is noticeable. It uses the second speed until it is within 1 deg of the target temperature then switches to the lowest. I am not sure if my thinking is correct, but i assume a high level heater will require a higher speed, as it is trying to drive the heat to floor level. I knew the heat output of the existing radiator was low as it was shown in the initial survey before the heat pump was installed. One other thing that may be of interest, i am only 3 days away from the first full year of using a heat pump and the total KW used today is 3948 kw. The house is 2 bedroom ex council built in 1937. with a total of 8 radiators, 2 towel rails. I hope you all have a good Christmas and please stay safe.

I have just noticed this thread and will give you my experience with this scheme. I applied for funding for a LG ASHP on the morning the scheme opened. My voucher was issued on the 27th November 2020. My supplier gave me 5/1/21 as the install date which was then changed to 15th December. Commissioned on the 19th dec. Supplier was paid on the 5th February 2021. It would look as if i was lucky after reading some of the posts. I made sure everything that was asked for was complied with and i had my quotes long before the start date for applications. As a matter of interest, it was a relatively small company i used and they were very good and i have had no problems with the installation.

/ I don`t know if the following settings are the installers or if I have changed any of them, so here they are. Low water temp for auto mode min 34 max 46 Outdoor temp for auto mode min -7 max 21 You can be sure if I changed any of the settings I had no idea what I was doing.

I thought the AI settings were in degrees, but that really was a guess. This controller really does try my patience. There is so much that i read that confuses me even more. I see you say THINK, so that makes me feel a bit better. Perhaps when winter comes i will know a bit more about it and be able to use the settings to control things better.

I don`t know if this is relevant or not, but if i leave the heating on all the time, AI setting at -5 the heating does not come on. The circulating pump does continue to work, on for a minute or two then off for the same time. The buffer tank is always cold, showing 25 deg flow and return. I assume this is monitoring the AI settings. I now keep the controller off as the hot water continues as normal on the timer settings and the pump does not run. The buffer tank as far as i can see is always cold.

Surely using this element to heat the buffer tank would be a step backwards., unless you were having problems getting up to the required temperature due to extreme cold. Out of interest, now that the heating is no longer required, i am using roughly 10 kw a day for hot water, cooking and all the other things plugged in 24/7. Is this what you expect for 2 people in house.

From what i can see of your cylinder it looks identical to mine. Perhaps they sell the same thing under different brand names. I can only see a small portion of yours in the picture you uploaded.

Hi, I had a 7kw LG heat pump installed by this company in December 2020. They are a small company, and i had no problems with them. Jamie the owner could always answer my questions correctly, and even when i managed to stop the system working when changing things in the programming, was able to fix it over the phone in a matter of seconds. I did cast a plinth so there was no time wasted when they started, and lifted all the floor boards as i needed the micro bore changed for the heat pump. I am located near Durham. They are worth contacting, and you can form your own opinion of them. The company is Lucans ltd located in Tyne and Wear.

My house was built in 1937 ex council and was used for many years by miners. It has cavity wall and attic insulation, double glazing and nothing much else. Small 2 bed with 2 pensioners. House is all electric and heat pump was installed just before last Christmas. 17 Feb to 8 may 81 days, total bill 203.42. This is comparable with the combi boiler we had. I am far from being an expert on heat pumps, but it works fine for me. At no time has the house been cold always around 20 / 21 deg. The heat pump is a LG Therma V 7 kw.

The cylinder is a world heat 150 L superflow The biggest I could get into the available space.

I think you are correct with your statement. I am the first to say I am at times bamboozled with what a lot of the settings do, or are meant to do. I am old so at least I have an excuse. I am hoping when winter comes around, I will be able to run AI mode and perhaps be able to run the system constantly, at reasonable cost and comfort level.

I have been trying to upload a pic of the heat pump and tank with no luck. I will try this time using my phone

I have checked my settings and are as follows: Outdoor temp for auto mode min -7 max 21 LWT for auto mode min 34 max 46 Some of these settings were changed by me and were left as i set them as they did not appear to make any difference. I really need to wait for winter now as i understand more about the system now than i did. I have been using the AI setting the past few weeks and when it comes on at 07.45 it heats the house up to about 19.5 deg and does not come back on all day. I assume there is very little heat loss. I have been spending a bit of time trying to analyze my octopus go account.and one thing stands out. My in home display is showing the daily spend far in excess of the actual from octopus. The IHD was showing as much as nearly £6 a day when very cold, but the max from octopus was £3 a day. This makes a big difference to my perceived dailly costs which were at times alarming. I could not check this during the winter as the first account from Octopus was for a 3 month period. I only moved to Octopus in February and the way they breakdown the account is the best i have seen. Each day has a graph and consumption reading every half hour. There is little doubt in my mind that i will be very close to the same costs as i had using the combi boiler. Time will tell, and i will update this next year !!!!!!!

Yes I have meter but would need to remember to read it every day to have daily readings. The access to the meter which is fitted beside the tank is from outside, it is in the old coal store built into the side of the house. The only place where I would but a fan assisted radiator would be in the kitchen ,so noise would not be a problem.

I have a totally different question in regards to radiators. I kept the existing radiators when the heat pump was installed, as they were all double convectors and oversized, except bathroom and kitchen due to space constraints. I have been looking at low water content fan assisted radiators which unfortunately are very expensive. The cheapest i have seen are Smiths eco-powerad fan convectors. The water content is approx 0.5 liter so should shorten the time to heat the system from cold. Does anyone have these or similar as i would like to know more before buying one to try in the kitchen. As an aside, now that it is spring, my heating is on from 08.00 to 19.00, set to AI and the total usage including cooking is just under 14kwh which i am very happy with.

Hi Chris, I have been running on AI for the last couple of weeks as using this setting during the winter did not appear to be doing what i wanted, never warm enough. At the present time, the heat is set to come on at 07.45 every day and is on until bed time. We are long retired so always at home. I was looking at how to limit the temperature of the radiators, but had been unable to do this in the settings. After noting your comments re the radiator temperature in AI settings i had a look at the data logging and i see the max temperature of the radiators has been 44 deg. This is what i wanted so you have helped me there. The problem with the controller is there are settings i do not fully understand, and even googling them does not turn up any help. If you have used 7800kwh with your set up this indicates to me that my running costs will be fairly comparable with the combi boiler. I do note your comment not to look at the smart meter. What i was missing was the fact the kwh used, drops dramatically after the very cold weather. I pay attention to all the posts as i am learning a lot from them. Many Thanks to all.
