  1. Try way back machine. He may have dumped the buffer, it was there when I last visited. Not sure if the slab mass makes a lot of difference to the cycling once it is at operating temperature. More to do with the flow/return temperature differences. A kg of water needs 4.2 kj to raise it a kelvin, concrete only needs 0.8 kj. So a kg of water is worth 5 of slab. And all the water can be heated, but there will be a temperature gradient with a slab, which may effect performance.
  2. He had a buffer. He also used to to preheat water going into his original Sunamp and to recharge the Sunamp.
  3. Half the customers on that job were happy. So that made 2 our of three of us there. If it had been a vote for BREXIT, I would still be in.
  4. Here is someone I know. Scroll down to see his name, no wonder he has a stutter.
  5. I had them screwed shut when her husband came in.
  6. At my Public School it was a couple of Jocks. Ben Doon and Phil McCaffity.
  7. Did you end up with a Manx Cat?
  8. When I was in the PV industry they changed the MCS rules about fitting inverters in lofts. One of the rules was boarding from the hatch to the mounting area. My boss just saw this as an extra expense. The electrician we used said it made for a much quicker job to fit the inverter. Fitting loft boards takes minutes. Why would anyone not do it.
  9. More a reflection in the borrowing and earning potential between I side and outside the M25. And people from Treacle Bumstead are tossers.
  10. Yes. Why I did it for a couple of years when I needed extra cash. Small capital outlay, very cheap insurance, and everything fitted in the boot of a mid 90s Corsa. Could earn 3 times the money in Harrow compared to Hemel Hempstead. Only got thrown off one job, but that was nothing to do with the decorating.
  11. First rule of statistics: Is the number big. It was our old mate @Ed Davies who pointed out that the UK produces more 'area' of cars than housing.
  12. Was true in the private school educational system, but matron usually managed to remove them.
  13. May be more of a case that getting older is unhealthy.
  14. https://mechanicalbasics.com/reversed-carnot-cycle-process-cop-limitations/ Probably getting close in some circumstances. They can go higher than 5, but this is not really the way it should be described. They performance should be as a fraction of the Reverse Carnot Cycle. Similar to how wind turbine performance is expresses, as a fraction of Betz Limit. https://physics.stackexchange.com/questions/350074/is-there-some-theoretical-maximum-cop-for-heat-pumps-and-chillers Choice of gas is important, ideally you need to work close to either side of the critical temperature. I believe this is done in CO2 systems. Water would make a good refrigerant, except it would not work that well below 273k.
  15. Will it work this time? https://www.independent.co.uk/climate-change/news/climate-emergency-gas-boilers-cop26-b1902658.html

  17. I have not bothered to look into this much, but there is a CO2 equivalent with refrigerants. But not all of them will leak. Natural gas, by its very chemistry, will produce CO2 when burnt in air. Electricity can be very clean. There is also an infrastructure issue, we have one network that is multi use i.e heating, cooking, lighting, machinery and transport, and another that is just heating and cooling. There will be a carbon cost to that.
  18. You will almost certainly have a hotspot router on your phone. Try that out first.
  19. Now you are in a much milder climate (was it Kent before), you may find yours heating demand is lower.
  20. Before considering SBB, have you tried your, or different, mobile phone 4 or 5G offerings?
  21. Apart from capital cost, why do you think it is unsuitable? Same question?
  22. This is a difficult one with a shed. Depends on the differences in humidity and temperature between inside and outside, if it is heated/cooled and how often people work in it. I put the vapour barrier on the outside of mine as it is unheated and I very really actually do any work in it. I also live in a place of high humidity. My thinking is that keeping moisture out would be most effective rather than the condensation risk. Worked well.
  23. I once had the external waste downpipe freeze and back up into the toilet, was the winter of 86/7. No idea why it backed up in the first place and it thawed the next day and never happened again.
  24. It is worth pointing out, that @Dave Jones, claims to have had an ASHP installed once than it failed to perform, He has never offered any evidence i.e. house heat load, size and make of system, age of system, running cost, an invoice to show installation cost, DHW flow rates etc. What he has done is pop up on just about every heat pump thread claiming the same faults will occur with all ASHPs, and the only solution is a gas combi, but never mentions what size combi would be suitable. He even claims that a gas combi is suitable for people that have stated that they have no gas. The mods, who are quick to delete some cheeky comments really need to do something about this.
  25. The definition used to be more than 10% if household income, then it changed to 8% of free household spend. It is a total nonsense as there is nothing special about 10%, or 8%. What is important is stopping low income household getting into ongoing and permant debt, either by policy i.e cost of living rises, or lifestyle choices i.e addiction or lack of education. If we think it is expensive to bail out even the reckless, try the alternative of not bailing them out.
