  1. My Nightmare Heating System

    The Hoselock is to fill and pressurise the system on commissioning or if it needs topping up for any reason. (It's a sealed system and not directly connected to a water supply.)
  2. My Nightmare Heating System

    Possibly. If it has been stagnating for ages the anti-freeze will have deteriorated. For all I know it could have turned to jelly. In your case it's probably worth flushing it out and putting new glycol in, when you've found out why it's not working.
  3. My Nightmare Heating System

    If the system doesn't leak it shouldn't need any periodic flushing. My system with twice as many panels has been running for getting on for 8 years and has only needed refilling when I've modified it and never been flushed. (25kWhr harvested today!)
  4. My Nightmare Heating System

    At most he will have supplied a bit of Cu pipe and couplings. The IDA invoice (page 1) shows that they supplied almost everything, including antifreeze. There's a picture of the first panel frame in situ on the blog, probably doesn't help much, but tells you it's a roof mounted system. The collectors are 30 x 58mm evacuated tube types.
  5. Well, I replaced the drum bearings on my direct drive LG machine, but it was 8 years ago and I can't remember any details. It wasn't that difficult though, apart from working in too small! As generic guides I've found the espares ones useful. https://www.espares.co.uk/advice/howto/how-to-replace-washing-machine-drum-bearings
  6. My Nightmare Heating System

    Re the solar installation. The parts were supplied by a company trading as Economical (http://www.eco-nomical.co.uk/). They sold relatively inexpensive Chinese evacuated tube panels, not the most efficient but perfectly OK, my system was mainly supplied by them. If the system was turned off the anti freeze is likely to have degraded, can't say if it will solidify or not but even if it has it will only be at the top of the collectors which is a straight tube and should be easy to clear (apart from getting on the roof, of course!) The pressure gauge reading is OK for a sunless day, when the sun comes out it should increase. If the pump (the circular thing under the controller) is warm but no water is circulating it is possible that the pump is seized. Should be easy to fix if that's the problem. Solar systems are fairly simple so there's no reason why it shouldn't be fixable.
  7. Log burner

    Yes. We've got 3 plus a coal Rayburn (our house needs heating) and they are almost unused - one was lit twice this winter. They are messy, wasteful of space and will almost certainly overheat your rooms if you have reasonable insulation, when run hot enough to minimise pollution. Although I understand the appeal I'm completely bemused by people with near passive houses insisting on installing them. (And they're stupidly expensive for what they are!)
  8. A tape and water level should be perfectly adequate for setting out, but laser measures are brilliant tools. I bought one of these https://www.powertoolworld.co.uk/bosch-glm50c-professional-laser-rangefinder-0-05-50m recently and wish I'd got one ages ago. They're not wonderful outside as it can be difficult to see the spot in bright light, but you can measure things single handed that would be very difficult with a tape. E.g. I'm rebuilding some outbuildings and I wanted to check that I'd got the rafters parallel over the length of the shed. Standing on a ladder 2.5M above ground I could measure 9M quite easily with the laser measure, not at all easy with a tape. It also has an inclinometer so easy to confirm the roof slope is right.
  9. I bought some heating mat and insulation from them a couple of years ago. It all arrived in one piece, so no issues with them as an online supplier.
  10. Air pollution monitoring

    The sensor is at the same level as the boiler about 10M away. Most of the particulate peak will be due to spill from the fire box door.
  11. Air pollution monitoring

    I bought a purple air monitor a few months ago. I doubt that JSH would be interested; apart from the cost it's very much an IOT device. It demands an internet connection so has probably got lots of security holes and it uses Google maps. They're system isn't setup to let you store data locally easily, which rather surprised me. I scrape data from the devices web-server and store it locally, but, for some bizarre reason, the data gets flaky if the internet connection goes down. Having said that, it does give quite interesting results and useful comparisons to other sensors; there are about 10 in the UK now. The main reason that I bought it was to check pollution from wood burning; our house is heated with a log boiler. Apart from lighting and refuelling there is no measurable increase in particulate levels over the very low background. The peaks when starting are usually less than the particulates I get when roasting coffee, and they are over much more quickly! IOW, burning wood doesn't have to be a source of pollution. Another thing that I've noticed is that sometimes you get an increase in particulate levels over a wide area (most of southern England) which has no obvious cause, but stops quickly if you have an air cleaning event like rain. I guess that this could be pollution imported from abroad. This shows most of the English sensors. https://www.purpleair.com/map?&zoom=8&lat=51.98340589327153&lng=-2.0000451278685887&clustersize=30&orderby=L&latr=3.271820379132471&lngr=6.2567138671875
  12. Gamekeeper turned Poacher!

    Heating costs are actually a pretty small part of the running coasts of a house, so, even if you are one of the tiny number of vaguely rational people, it's not going to come high on their house purchase agenda. It's still location, location, location (and then kitchen!) EPCs have no good relationship to heating costs. Our house would have an EPC of D or E without the PV systems, however the PV systems bring it up to an A. Having PV doesn't reduce the heating costs of the house. We still have several single glazed windows, which will be looked on with horror by other forum members, but it makes no economic sense to do anything about them as the extra heat loss is relatively trivial and the aesthetic implications aren't trivial.
  13. I'm the last person to defend solicitors or conveyancers, but none of that is their job. Their prime function is to ensure that the title is correct and to transfer it properly, an easy process with registered property.
  14. How binding is an offer on a plot?

    The process for buying a plot is the same as for buying a house. If the house is freehold, in both cases you are buying land, which happens to have a house on it if you are buying a house. Making an offer is the same in both cases and you can back out at any time before exchange of contracts, but so can the seller of course!
