  1. I run 2 zones upstairs and downstairs. Gone back to a 4 port buffer and now got a balancing valve on the return heat pump side. Seen the short cycle reduced in this mild temperatures. Probably not the way for a new build but I live in 1930s solid brick house and with one room can be 21c and the next room 19c, completely different scenario to a new build. I use my stats as a temperature limiter, weather compensation set up for a max room temperature 21c @ -3 room stats set for 21.5c. The other reason is cooling in summer it’s needs very little cooling downstairs but upstairs is very warm for sleeping.
  2. My extractor fan in the downstairs toilet is louder than my grant aerona3 unless it’s doing a hot water cycle the compressor noise is louder.
  3. My grant anerona3 hardly goes into defrost, it is sat on my garage roof gets plenty of circulation up there. I hope the new ones have a modulating water pump rather than a fixed one on mine.
  4. I used Weber floor system in my hallway needed something that could take foot traffic in 3 hours. It’s 50mm thick I used Ritmo render machine, 22 bags in 30 mins. It was warms up very quick compared to my traditional floor screed (65mm) in my kitchen but that keeps the heat way longer. Bag screed costs 3x times more than traditional screed.
  5. My living room wasn’t hitting 20c I wanted it to be, tried increasing the flow temperature that didn’t work. In the end I drop my flow temperature down back to original temperature and dialled my flow rate on the hallway Ufh and now it’s achieving 20c, hallway is still hitting 20c aswell. you might just play with it’s the balancing, how loops do you have?
  6. Good video on how to work it out. Don’t know glycol heat capacity, someone will know here.
  7. Since I replaced my radiators with fan coil units and dropping my flow temperature down to 32c it was short cycling a lot. Managed to balance my pumps got better run time, turned my max flow temperature to 35c and now getting 4 hours run times. I don’t know why but my grant aerona3 doesn’t like super low temperatures.
  8. Good job I swapped over to octopus cosy this morning! I’ll swap back in April.
  9. Just checked no it doesn’t. So 18.4p/kWh including VAT. 19.40p/kWh standing charge and VAT. Which isn’t bad since I’ve used 9000kWh
  10. 6/12/23 to 6/12/24 I have averaged 17.56p/kWh not including standing charge, to be honest I’ve not be bothered when we use it so you could get that number down if you want to be careful. I’ve got a 3rd party app called octopus watch, works all my history out and just told me octopus cosy will be cheaper than agile based on my hourly consumption.
  11. I have no idea why it’s that high. Most expensive slot today was 48p/kWh which is a tad higher than normal. I keep having days where I’m paying more than 23p/kWh average, so it’s time to have a look around.
  12. I might have to look. I’m on octopus agile and tomorrow it’s hitting 91p/kWh at its most expensive slot! Most of the day is around 40p/kWh
  13. I took my mixer valve off my Ufh on Friday, on Saturday I had 26c floor temperature on 32c flow temperature. I had engineered wood flooring glued down, manufacturer recommended temperature limit is 27c. I’ve trimmed my flow temperature and I’m gonna fit a sensor to knock the Ufh off when it hits 26c. Think you might struggle with 45c flow temperature unless you are using suspended spreader plate system
  14. They just released 5kw and 7kw versions but at £7000… Think it’s a very good idea.
  15. Shame I have a 6kw heat loss.
