yes sorry 9p.. yes just a strandard DD tarrif was on OVO swapped over within 1 week of applying and worked from the get go , no messing, no faf , had been trying to get on octopus flex for 6 months .. gave up then found BG worked out a better deal anyway .. IMO

Some of thsoe Octopus tarriffs i struggle to make sense of ,, and gave up trying to get on their flex ine ... out of all of them we found british gas to be the most simple for us.. just works , just a straight .09p form 12-5 am 30p all other times , half price 15p on sundays.. export 15p kwh no fancy ev meters just use what you want.. when we need to import we buy 95% of electric requirements at .09p or 15p , this to charge our house batteries our bmw i3 ev car, and charge our floors with heat floors via ashp.. Only needed that Nov-dec. jan feb on consec cold days below 6 degree .. PV & batts covers all other months we run our enture 4000 sq ft house, energy /heat and our i3 ev car for less than £100 per year all in total.. and hoping to get that a new zero or negative cost through 2024 -

have on of these in my 20m x 10m garage . works a treat self fitted in less than 3 hours.. super effective , heat in winter, air con in summer and dehumidifies at same time. https://www.appliancesdirect.co.uk/p/eiq-9wminv/electriq-eiq9wminv-air-conditioner?refsource=apadwords&utm_source=google&utm_medium=cpc&utm_id=18004559423&gad_source=1&gclid=EAIaIQobChMIwYiXqpmygwMVLSzUAR2EMAyGEAQYASABEgKrDfD_BwE

Nially, it must be super frustrating that your loop has failed, in such short time . i woudl be livid ,, whilst I cannot add anythng for a news system, i am interetsted in teh loop install, im wondering if you have any pictures of open trenches ? IMO laying of pipes in trenches can be tricky to keep perfect loop and back filled all perfectly radiused .. im sure that if your pipes have failed then others must have or be about to .. is it not possible it could be a manufacture defect in the pipe make up.? we had a whole house fail in copper once with the copper pipe having defect pin holes.. the manufactures insurance picked up the entire refit.. what did teh manufacture recommend for the loop radius and what was installed ? there certainly doesnt seem to be many incidneces on teh internet of failed loops, and considering how little attention groundworkers pay to the the small details , if the loops were so super critical surely we would have more issues ? but if its installed not as manufactures details then surely the installer insurnce woudl pick up the costs.. or would you house insurance cover this even? I would be pretty worried if i had aground loop after reading your failure as i iamagine others would, .. FYI in our last house we had an ASHP that ws 6m away from house on garage wall , with buried flow and return pipes that were highly inulated.. so they dont have to go right on the house wall..

its working well for us. i . i also have a log burner that is plumbed in to heat hot water or under floor.. everything is auto matic .. if we fire up the log burning it switches off the het pump once it reaches 50 degree flow temp out log boiler, (assuming we have ashp pump on and thermostats alling for heat.. .. a local company throws way sawdust briquetts , we bur these.. log burner gives 2kw to room and 7 kw to water.. i dont really need t heat the bathrooms just a hour or so every couple of days to keep floor so its nit ice cold.. in these rooms we use infr red heaters,, flick em on 5mins before you go for shower and turn off when you leave.. makes room super toastie and cost way ess than heating the floor to heat the room .. there are many other tricks you can do when deigning a new house , that allways gets just missed..

sorry my bad not enough coffee,, yes thats correct at about 0-3 degress and intake is about 14kwh over that period the 10kw pump maxes out full chat and rquires 3 kw -3.2kw for the 5hour stint.

get on an overnight cheap EV =charge rate and run that ASHP full chat charging up your floors during that time .. then step it back during the day.. this could save you some ££ , you have to look at the whole year costs .. ASHP are way more £ to run during cold spells to get temoerature up (hence teh overnight chep tariff) compared to oil or gas IMO , but soon pull that back in late autumn and erly spring so that over the year you should be more economical and cost effect ..

i run my grant arona 10kw heat pump, flat out , between 12.am and 5am using cheap over night electric.. during that periord at about 0-3 degrees it uses 10-14 kw of power.. my thermo stats are all calling for heat higher than it will ever reach .. its just pumping heat into the floors .. i have the weather comp set at 50 degress at -3 external .. this is into my buffer tank , but i have recordeded retirn tems of 40 degrees from teh underfllor loops.. i designed my house to run at Under floor flow temps at 35d at external 3, but this would be leaving it running all the time .. and it works perfectly, , but its way more cheaper for me to utilse the overnight cheap rate and charge up the floors as much as i can for teh 5 hour period then turn it off (cost to last year are about a 1/3 ) I have a large 4000 sqft house. all with under floor heating .. during this perior we heat bathrooms, kitchen , family room , living area .. ( bedrooms dont require heat..they stay warm) the charge into the floor make the whole house snug and warm .. we may light log burner in the evening but this is more creature comfort rather than nessesity.. at the same time over night we charge our 10kw batteries ,, this mostly enough to run our house , do our hot water via teh heap pump and electric cook.. if we get a bit of sun its enough to boost the battery by 30% (7.2kw 5 degree facing west rray) to last out till the 12am charge time.. if not and we do a big electric cook we may need couple of imported kw.. House is new, i(designed by myself )contemporay design, open plan iving areas with solar gain in winter if its sunny .. floors are covererd in either amtico , tiles with carpets in bedroom.. (wood floors what ever they are are just terrible for low grade under floor heat efficiency we learned that mistake the hard way in our last house ) we basically pay about £2-2.30 - britisg gas 0.09p kwh (standing charge aside) deending on temp say 5 degree or under to heat and run our 4000 sq ft house per day .. keeping it super comfy toastie thsi way.. we only really need to heat november / december /jan feb march.. if you woudl like any more details or soe energy graphs ask away, but using over night to pre wrm your house works brilliant, teh more isnulation and draft proofing you do to retain that heat then it has every chance of being your only heat time required.. kind regards Andy

lol.. since when did common sense become scientific.. if who ever is designing your extension home, is not clever enough to sort/design shading as part of the package then perhaps they should not be undertaking such work.. its very simple.. the sun and how it tracks through the season is a known quantity.. you can even use google sketch up to map the shadows.. .. The key to a good liveable design is not just how it looks but design consideration to how it works and will be lived in.. making use of the sun , making use of shade, cross ventialtion , and natural ventilation via convection.. simple skils that cost little for the home owner.. if you have to instrall air con in the uk other than say a bedroom for a house to work.. then i agree with the poster above .. the initial design is lacking

A solic was tried, and near useless with batteries, Solic confirmed it does not work.. it just drains them... so it was removed .. The idea was to heat the water automatically so as to cost me nothing.. I have no heating and tiny electric bills .. I have now set my hot water timer to 12.30 - 2 pm. via the heat pump. even on a cloudy day from march onwards it appears my array has enough power at that time to run my ashp and heat my water it takes about 2-2.5 kwh .. so no cost during winter i use a log burner with back boiler for hot water & underfloor heating.. when my house needs it,, which isnt very often.. thanks Andy

If you say so..

From my post in another thread.. may be usefull "I heated my 300l DHw that was down to 22degres to 54.7deg in 90 mins , The energy delivered to the heat pump was 2.6kwh . total , with peak draw hitting 2.5kw twice during the 90min session. it was heated in about . outside temp was 11-12 degrees .. " i can heat the same volume in about 50 mins to a higher 63 degrees ,, if light my wood burner with back boiler , about 1.5-2kg of wood

5 degrees West .. appears to be more pruductive at this time of year than my south facing system at 37 degrres on my last house .

Yes your presumption is correct.. big fingers little keys .. thanks

If anyones interested : some real life data today, I heated my 300l DHw that was down to 22degres to 54.7deg in 90 mins , The energy delivered to the heat pump was 2.6kw . total , with peak draw hitting 2.5kw twice during the 90min session. . outside temp was 11-12 degrees .. currently I have x2 3.5 batteries and both were charged to 100% before I switched on the HP.. it was bright with cloudy / sun today, and the 7.2kw panels (west facing at 5 degee. off flat covered the water heating costs... .. leaving the batteries untouched.. we then exported another 5kw this afternoon, so a third battery would have easy been charged .. ..even still in March .
