  1. Thanks for locating this Jack! Could you clarify what you mean by correctly set up? Is this in terms of what the system components are and how its been installed/piped/wired? [Dont know the ins and outs but we have ASHP, HWC and UFH/radiators for heating and looks like a pretty standard install]. Or did you mean the set up on the controller? Dont want to mess up or break anything..
  2. No fan coils- UFH on the ground floor and vertical radiators on the first floor. I was hoping running the ASHP in cooling would give some marginal benefit. I spent a good few hours trying to find the manual online with no luck- think I did somehow find one on my phone the other day but it wouldnt open without a password for some reason. Tried emailing Midea for info and they replied with: "Unfortunately this is something we are unable to advise on, your system would have to be designed for cooling, if this was just switched on it could cause damage to the heating system." Basically they want me to go back to the installer (who no longer operate). *Sigh*
  3. I have a Midea, model MHC-V12W/D2N8-B. Desperately looking for some way to take the edge of this heatwave so reviving this thread. Anyone able to assist?
  4. That was Version 1 of our plans. Ended up having to move to the utility/plant room to reduce costs (and to keep things inside the envelope)- then things finally got shoved to the loft as my wife wanted a "nice" utility room. Compromise at every turn as per usual! 🙄 Been discussing with the guys at Midea and they have come down to £250 up front payment which works out at £20.83 p/m- Inspection of cylinder, expansion vessels etc also seems to be included. I will sign up to this and just let the Telford warranty lapse. Appreciate the advice guys!
  5. Completely agree with this which is why I dont pay for any other extended warranties. If something stops working before it aught to, i'm happy to use the sale of goods act with the retailer to get a repair. (Did that previously when my TV failed). Its just the worry on safety and losing hot water/heating during the middle of winter. Think I will get the Midea plan for now then reassess 12 months down the line.
  6. Thanks guys- good points. For the HW cylinder I am leaning on doing my own inspection but its in the loft and above our kids bedroom and thats a big worry for me. Yes coming from a tiny 2bed terrace with no water meter- bills have been a shock to the system. ☹️
  7. Been happily living in our self-built home for just over a year (thank you again Buildhub for all the help and advice during the long and tricky process!) Now i'm on the other side i'm slightly tearful about the running costs (water, electricity, council tax). Grimacing now at the servicing costs for the heating system. Midea (ASHP manufacturer) are quoting £29p/m for the Mi Care service plan (link) which apparently is needed to maintain the 10 year warranty (found another company that can offer a similar service plan for £15p/m but warranty would lapse). Separately our Telford horizontal cylinder also needs its own annual servicing (cost £245+vat) to maintain its lifetime warranty. Do I just suck it up and pay for this now every year? Would be interested to know other peoples views.
  8. I'm going to apply for the 5K government grant for ASHP- will this dictate whether the heat pump can be run in cooling mode?
  9. Funnily enough also looking at this what with the weather we're having! We are going with ASHP with UFH downstairs and radiators upstairs. From what i've gathered through scanning the thread the simplest method would be running the ASHP in cooling mode with the UFH taking care of the downstairs- the neatest method for the 1st floor would be fan assisted radiators in the bedrooms. I cant however find these after searching- anyone can direct? Second question- is it worth getting a more powerful ASHP than required? Would there be tangible benefits to the level of cooling?
  10. Of course. Price of gas connection was £2k plus £5k for the gas heating system- ASHP was coming in at over 13k. I will probably switch/add ASHP down the line at some point though but I think at the moment i'm comfortable with this choice. Will definitely get an induction hob with 1 gas burner.
  11. For reference having looked at the numbers I have opted for mains gas and a system boiler installed. The (none-diy)ASHP option was significantly more expensive even accounting for the cost of connection so I just couldnt justify it. -The house will be well insulated so space heating requirements should be small. -Solar PV will primarily be used to heat the UVC throughout the day with boiler for support. -The UFH and radiators will be designed for future compatibility with a heat pump further down the line. Thanks all for the advice- its been a really useful exercise going through all these options and has brought lots of things to my attention that I should really have considered ages ago!
  12. Thanks again for the links and everyone for their replies- been doing more reading and i'm kind of getting snippets of useful info across several different threads as opposed to one. I think i'll try to get a direct cost comparison quote between a system boiler + UVC and an ASHP + UVC, with both UVC's (400litres) having immersion heaters that can make use of the PV energy. I'll have a go at calculating with the spreadsheet what size of system I will need but I'd be grateful is anyone have a very rough ballpark figures for the costs of the equivalent systems given our house size and occupancy. @Temp This is a good suggestion - we would only use a bit of gas so that particular cylinder would last us years! No experience at all with cylinder gas but the one you use seems quite big so do you keep it inside or outside? I assume there is a regulator that you need to attach to it- does this need maintenance/replacing after a period?
  13. Thanks Olf- could you point me towards which section it is in? I was looking around all yesterday evening (maybe in the wrong places!) before I posted the thread and couldnt find anything. Yes we are going induction but with a single gas burner. Most of the cooking would be done on induction but there are a a few things an open flame is better for.
  14. Hi guys- not been on here for a while as my self-build project has been EXTREMELY slow in getting off the ground. Things however are now starting to move with the site now cleared and setting out taking place this week. Long story short hadnt really put much thought into the plumbing and heating side of things besides a short chat with the architect where we decided to go for a system boiler instead of a combi (so hot water doesnt get interrupted). He contacted me last week though saying that if we instead use an electric boiler (which can be partly powered by PV) this would be a 'greener option' and also save £2k on the mains gas connection (main contactor pc sum). Obviously I would never go for the electric boiler so I would have to install an ASHP +UVC so i'm sure upfront cost would still be higher. Builder strongly recommends to have a gas connection over not having one as it gives flexibility down the line- install a gas boiler now and then either replace or use in tandem with an ASHP later. (Wife wants gas for one of the hobs- but i guess we could bottle for that). I've been reading as much as I can on here and the majority who did not get a gas connection was because it would have been pretty expensive/they were off the grid. For reference Home is ~200m2. 100 downstairs- HW for wc, utility and kitchen; 100 upstairs -HW for ensuite (shower) and bathroom (shower) Well insulated with Solar PV system 4.5KW (SE facing) 2 adults, 2 children occupying with occasional guests. Any advice on what makes more economical sense would be really appreciated (note im not prepared to go the DIY route). The ending of RHI and start of the boiler upgrade scheme in April (which I think self builders qualify for) makes things a lot more murkier. First fix scheduled in Feb- 2nd fix April but our builder needs a decision on the gas connection really soon so starting to panic a bit! ? Help!
  15. Wasnt sure where this thread should go- hopefully this is a suitable place. I had been chatting to someone about the new government Green Homes Grant (due to start this September). Details arent completely clear at the moment but vouchers up to £5000 are being made available to support improvements made to homes in the form of insulation or low carbon heating. Was just wondering if anyone knew where self builders stand in all this? Would we have to complete the build- THEN apply for a grant to help pay to install something e.g. ASHP? Cheers!
