Yarddirect. Negotiable on price if order sizable got the electric hub thrown in too. Helps if you order blinds too

Snap shot of today, internal 21c, external -3.9c, flow, temp at manifold 33c return 28c, delta T at boiler 6.5c accounting for first floor rads. Boiler modulation 18.1% equivalent to 4525W and gas shows 5200w almost steady, constant burn all night no cycling. ChatGPT offered the following up. 250104Temperature_Heat_Loss_Report.pdf

I have been measuring, for a few weeks; outside and internal temps, boiler modulation, cycling, flow and return temps at both the boiler and manifold and finally actual gas usage. Subsequently fed all this into ChatGPT which gives me a heat loss at 0c actually measured of 4.58kW over several days. I have kept a steady 22c internal temp, .projected heat loss at -5c is 5.7kW. I therefore think a 7kW ASHP would suit. The boiler and tank are adjacent to each other, situated in the utility with room for the heat pump control with the fan unit on external wall, the primary circs would be less than 4 feet long. My emitters need no interference, as they have proved themselves adequate running at a flow temp of 33c, the boiler is cycling about 1 and a half times a day. I have a facility for a 6mm additional radial circuit in the utility. My tank is fine. There is a drain by the external wall for condensate. In essence if I were to swap it would be a very straightforward exercise. I know the prices of the heat pumps, I’m going to get three quotes for Viessman, Nibe and SteibelEltron all 7kW and see what they come out with the bus grant. I may be persuaded dependant on cost but I’ve a feeling they’ll be thousands above the bus grant, in which case, I’m going to sit tight. The heat loss calc will be interesting to see against my actual heat loss measured from real time data which is marginally better than my SAP calculation from 3 years ago which encompassed an air permeability test. I uploaded my SAP data to ChatGPT to confirm too, it’s an enlightening tool.

I guess to some extent it is to do my bit for the environment. As a money saving exercise, it is probably futile. Curiosity is also a factor and as is future proofing.

Here’s the stats for the boiler space heating vs DHW Measured at the boiler and it aligns with actual usage measured by Octopus. My other worry at a change would be how low the ASHP could modulate. We are in winter but although mild (ish) as my boiler does down to 2250kW at a COP of 4 the ASHP would have to go down to 560 watts. The boiler stays at minimum modulation for a while, today it has run continuously for over 15 hours and counting, modulating of course. What decent ASHP at say 7kW can get so low. It would be even more salient as thing starts to warm up to prevent cycling.

Happy new year to all. I have a EPC A rated 3 year old property with ground floor of 160 sq m and ufh. Additionally have towel rads 3 of and 4 first floor rads. Presently I have a Viessmann w200 27kW system boiler range rated to 11kW running at flow temp of 33c with a deltaT of 5 to 6c at the boiler. It also feeds a 500l high gain uvc, 3 sq m coil. My boiler is only 3 years old and all is functioning swimmingly. My heat loss measured during Dec is about 4 to 4.5kW. Additionally I have 14.8 kWp of PV and 30 kWh or storage. I appear to be system ready for an ASHP but the newness of the boiler and its functionality is holding me back from changing. last years gas usage, space and dhw was 14300kWh. I used 6.4 mWh of electricity and exported 11mWh at 15p a kWh. What would you do?

Secondary return for me with the pump plugged into a smart plug. Set schedules or just tell smart speaker to run the pump for 2 minutes as we do. No excessive heat loss and hot water at furthest outlet and others more or less on demand.

It is possible. Happening to me at the moment, new red line to take into account land under my control for visibility splays. New notice posted with 21 day consultation. This was agreed after a constructive meeting with the planning officer.

I have 4.25 kW of panels feeding into 3kw inverter and circa 10kW array feeding 6kW inverter. The excess generation over the inverter limits goes directly to the batteries in DC. see screenshot The 3kW inverter can actually deliver 3.2kW ac

I am, The 6kW inverter generally charges the batteries from PV and mains overnight. The 3kW inverters generally serves the house load. Both export excess AC when batteries full surplus from house load. The excess AC from 3KW can, at times, also charge batteries via any headroom from the 6kW inverter. Sound complicated but it works well. If I have confused matters, I could supply data logs.

I asked for a budget request with Scottish Power details of reply below. I got 9kW export limitation but no G100 as I used my existing solaredge 6kW inverter and fitted a new 3kW inverter. This is fed by a 14.8kWp array with3 X solaredge dc coupled energy banks totalling 29.1kWh. It was a breeze. Thank you for your recent email enquiry requesting a budget quote for possible generation installation at your property. Unfortunately, we are unable to provide available capacity for a site. You would need to submit a budget request for the load details you are looking to install. We would then raise a connections case and our Design & Planning Team would then be able to carry out network availability for the required load details. You do not need to submit an application at this time but, in order to raise a budget request, please provide: Applicant and site contact details (please provide contact name, address and telephone number) Location Plan (Geographical location of site) Generation (export) details If you have any other questions, please do not hesitate to reply to this email or call us on the number below. Our office hours are 08:30-16:45, Monday to Friday. Regards, James Dey SP Energy Networks Contact Team 320 St Vincent Street Glasgow G2 5AD

Why on earth is it going to committee if the recommendation is refusal? Why not refuse under delegated powers? Seems very strange, who called it in and why? Our application was called in only in the event of a positive recommendation by the officer. Bewildered!

It doesn’t even need to be continuous. Extract from my successful appeal 1. I acknowledge that the Council is not proposing to re-define the boundary of the settlement as part of the emerging Part 2 (Land Allocations and Detailed Policies) of the Local Plan. However, this does not convince me that the site does not form part of the village. I note that the house itself would not be positioned immediately adjacent to the settlement boundary and a gap would be left. I also acknowledge that the site is a greenfield site which lies close to a transitional point and is reflective of the wider countryside. However, the Framework does not preclude the development of greenfield sites as part of the exception referred to above, nor does it require the development of a continuous frontage. 1Appeal ref: APP/A0665/A/14/2228579

Why didn’t they request Biodiversity comment on submission like they did with the other consultees they are chasing up? Overwhelmed and playing for time.

Giving you the option to withdraw relieves her of having to write a report up and therefore perhaps embarrassing herself. It can often be a cop out. We refused and got the determination which gave us the meat and bones to appeal against and won with an award of costs. I imagine you granted an extension of time for determination? If you reapply there’s another fee. If you appeal the current proposal, it’s free. I suppose it comes down to how much you want you proposal as is.
