  1. Flow temp is fixed in Day mode, following the schedule, but is weather compensated in Low Speed. Not quite sure about Night Mode, If I get a chance this evening I'll delve into the installer menus and see what the parameters are for it.
  2. standby and preheat consumption should be listed in the TUV document?
  3. the Coolenergy controller will happily run variable flow temperatures at different times of day, the four timeslots have programmable setpoints for all three modes. Weather comp then "adjusts" these numbers. Plus the fan modes (high/low/night/pressure) alter the compressor's max speed too.
  4. are you reusing or selling the door? If neither, can you add hinges and a roller to *it*?
  5. A nice long mains cable that's *just barely* the right capacity might do the job...
  6. how low is low, and what does reasonably-priced mean?
  7. needs a delicate touch with enamelled pipe, but is cutting the F and/or M bits off it an option, if one is too big and the other too small?
  8. I've never seen a "proper" slowcooker with any kind of simmerstat or thermostat, they generally switch the elements between series and parallel to get different ratings? Multicookers a different kettle of kippers tho...
  9. Get a price for a bespoke unit from World Heat. You might be surprised at the cost, and you can get all the fittings where you need them to match the current layout which will save time and money. The can offer Big coils too.
  10. might be worth getting it typed to see what variety of disposal is necessary. There's the likes of Iota, Chemtest, and G&L Consultancy (who are good at surveying); they may also be able to make recommendations for disposal too. I look after equipment for all of the above, but you'll see the guys from G&L out and about more so they might be able to assist quicker?
  11. why can't you just move her stuff yourself to put the cable in and GET THE BLOODY JOB FINISHED?????
  12. @Mandana What makes the edgings from that System different to standard round-top precast, other than the colour?
  13. sure about that?
  14. I read that as total, not per hour?
  15. Plain white tile to match the tray... done!
  16. We've had a warm spell here and the ASHP has not to my knowledge run at all, but it's supply meter has gone up by 0.5kWh in three days.
  17. none worth speaking of. We've been stringing 50-100m cat5s round car bodyshops with 3-phase starters and inverter welders and never seen a problem. Now wifi OTOH...
  18. I think it'll depend more on the gas than the compressor, tbh. You need to make enough pressure to liquefy the gas so it can then be expanded again. The compressor will only be able to do this above a certain speed, and then the expansion valve can only throttle the flow a certain amount too.
  19. ^those v-tac grill battens are great, nice light off them.
  20. yep, but I'll stick it on here for completeness as it's relevant to the thread CE-iVT9 EN14825 64.181.20.04362.01 Rev.00 TR Performance Pages.pdf
  21. Absolutely. Same with COP too as the required temp combos may result in the inverter throttling-back as it strives to achieve the most efficient pressure ratios. Speaking of, did you ever look at that TUV document I sent you for the CoolEnergy unit?
  22. ^yep DC injection would do it. I've just re-read the TUV report for the CE-iVT9, and it quotes standby at 9W and the crankcase heater at an additional 33W
  23. Pretty sure most quote min and max outputs? Ours is quoted at between 3.38 and 9.51kW depending on temperatures
  24. Hopefully we will find out with a bit more investigation. How low could a compressor motor go in the power factor. 0.5 is appealing. but it's not being "motored", it's a resistive heater at that point...
