  1. Do you know if I can buy any probe? Eg JG from Screwfix? If I need to buy schluter probes it will cost me £40 for two. I want to go through manuals of different thermostats and see which one suits me first.
  2. It's all quite confusing if someone doesn't have experience. I was hoping to just run the cable, tile and think about the rest later on. However, I've just realised no thermostat means not temperature probe. Given what I've read I may run two probes but need to get it asap. Can I use any ufh temperature probe with Ditra heat cable? e.g. I can get JG sensor probe from screwfix, then I may go with Warmup thermostat if it's better than schluter.
  3. I've found the cold cable! Is it possible it's 3-4m long for a 12.07m version?
  4. I bought ditra heat duo and their cable, no thermostat yet. I may have not done enough research but I was expecting a short section of unheated cable to deal run it under fixings. Any issue with running 60-80cm of cable under cabinets?
  5. Insulation level is low, standard late 80s build. That's the reason the radiator stays and the ufh will be warming up the tiles rather than heating the room. Any recommendations for cables, uncoupling mat, thermostat?
  6. I'm tiling kitchen and am expecting the floor to be colder in winter than it it's with LVT, so I want to put around 1.5-2m2 of electric ufh with an output of roughly 150W total. The idea is that it will be nicer to walk on warm tile but the kitchen will keep its radiator as the main source. Firstly, lots of different systems and I like ditra heat mat as it give a (very) little bit of insulation. Next I can get ditra heat cable but do I need thermostat from ditra too or is everything so simple in design that I can put a Mapei heat cable into ditra mat and link it with prowarm thermostat? Given I'm heating tiles not the room how radiant the heat from the cable is? Can I cover 4sqm of kitchen with a 150W cable (normally intended for 1-1.5sqm) and still expect nicely warm floor?
  7. But how to safely cap the pipe?
  8. My worry is how big the hole needs to be and how much screed will go over it
  9. How will he do it? I mean, how much does he have to dig out and how much screed will need to go on top?
  10. Gas pipe (covered in some sort of yellow wrap) is supplying gas hob we are now removing and changing kitchen layout. The same pipe goes to fireplace. What are the options to safely cap it and put tiles on top of it. I would prefer to run a new pipe to the fireplace but I don't know yet if it's doable without spending too much. I will obviously use a gas engineer.
  11. Anyone? I'm sure someone knows what the pros and cons are
  12. Just done some holes. 8-9cm of screed on top of old garage concrete floor. Based on kingspan calculator (7.5m exposed perimeter, 12m2 of area) I can go with either: 1) KINGSPAN THERMAFLOOR TF70 50mm + softwood T&G 2) kooltherm k103 50mm + sand cement screed 60mm. Shall I go with option 2? I like simplicity of 1 but it feels a bit outdated these days to have t&g floor.
  13. 1) Any good software I could use to calculate it? MRXBOXAB-ECO2B - probably slightly too small but I got it almost for free so want to test it first before going for something expensive. Also the house is leaking (old double glazed windows and no cavity insulation). 2) Do i need specific insulated mainfolds or just insulate it myself?
  14. I'm finally getting closer to my diy retrofit but (again) stuck on ordering what I need. Assumptions: late 80s house, 4 people, 4 bedrooms, 3 toilets/bathrooms (once renovation completed), location in cold roof. 1) terminal vents are on the roof and the size of the pipe is adjustable. MVHR unit has spigots 125mm but it's a cheap unit and I may upgrade it in the future if needed. Shall I use 150/160 galv ducting from terminals to mvhr and reduce it at the unit? It will be 3-4m run with 2-3 90degree bends. 2) mainfolds - any particular difference between fancy looking ones like zehnder/ubbink and stainless steel from lidab/quiet-vent? 3) mainfolds - is there any reason why some of them say they are not compatible with comfotube? I'm doing pick-n-mix so am worried about something not working when I start installing it. 4) Noise Attenuation - where shall I install them and how many ideally? Only between unit and mainfold? I understand the need for one in supply but what is the benefit of having one on extract side?
  15. That's a photo of bricks under window of the garage conversion
  16. Just a random thought, could it be that there is no insulation in my concrete in either of rooms (late 80s house) but the reason it feels cold in the garage conversion is due to cold bridging from either the other garage or driveway?
  17. That's what I was worried about. Lots of YTs and articles are from 5-10years ago, perhaps they tried to enter the market and it failed.
  18. I'm in a similar boat and trying to decide how to insulate the ducting from the unit. Is there any best practice as to what to use? I can see different products ranging from flexible sleeves to some rigid insulation.
  19. Why is VIP not practical? I have one quote for retrofit and it's £8k. So VIP would be just 1-2k and no mess. I may go for thin engineered wood or LVT but need to do the math on U values.
  20. There is PB inside but I would be surprised if it was 2 layers or FR. So, is there any for-dummies description how such conversions should be done? I get that fire resistance is important so that's something I would rectify. What about floor? If it's just concrete on top of concrete shall I try to skim it and/or put VIP insulation +6mm cement board/plywood + engineered wood? What can LA say if I go for retrospective permission given it's 30yo?
  21. Yes, thats how the wall of that room looks like inside the garage.
  22. Apart from the cold floor, how can I fix this room? There will be a lot of mess done in that room so I don't mind redoing some of the work but have no idea what the actual issues are. Regarding the floor, what am I looking for when drilling?
  23. We don't keep cars/motorcycles vehicles in the garage so fuel spills should not be a problem. The issue was flagged by surveyors but we accepted it. Question is what should we do now about it? Retrospective application for 30yo garage conversion?
  24. I know it's not worth when comparing to energy savings but there are a few factors: We have to remove carpets and do something like engineered wood, I don't want to loose more than 10-20mm height, the cold feeling of the floor in colder days is really unpleasant. I've already have a small corner of the room don using 25mm PIR + engineered wood on top (nothing in between) and it already feels a bit claustrophobic.
  25. No idea, we bought the house a few years ago. Neighbours say the conversion was done during the build but LA has no record of it. By the look of how it's done (eg.heating pipe running around sockets) it must have been done very unofficially.
