  1. Has anybody installed the radiator panels from 3Thermo that are designed to built into studwork walls and concealed by the plasterboard? Seems an interesting idea so wondered if anybody has tried to use them. https://3thermo.uk/
  2. As a matter of interest if standard ventilation flow rate is 0.5 ACH what sort of flow rate do you need to benefit form the heating/cooling potential from the air supply? I will take a look at the Blauberg range but I'm interested in both winter heating and summer cooling options and the cooling bit seems harder to achieve.
  3. So I'm guessing you are happy with the Lossnay unit? Did you source this through BPC? What size ducting did you install? If I was to install bigger ducts this should make it possible to move more air around without it becoming noticeable if the MVHR is sized form the outset for peak flow. But that is just theory and I have no idea if you can get bigger ducts and vents for domestic use that wont make the install look like an industrial unit. All part of the research. Comments greatly appreciated
  4. I'm still trying to figure out how to best combine a regular MVHR with an add-on to provide for additional heating/cooling if required and have come across the Mitsubishi Lossnay system that includes the option of adding a GUG Air Processing unit (datasheet attached) that can combine with a small ASHP to provide direct heating or cooling of the supply air. I'm guessing this unit could be added to any MVHR provided the system had been designed in the first place to allow for increased volumes of air flow to move hot/cold air around to achieve an effective cooling/heating effect. Has anybody any experience of such a system in a domestic house setting? Or is this kind of set-up mainly used for commercial buildings? GUG-010203SL-E_PI_SHEET.pdf
  5. Cost mainly and I've heard they can be noisy.
  6. Local BCO has approved a Septic Tank, so do not intend to go down the STP route.
  7. Looking for a bit of guidance on choice of Septic Tan and whether i need a vent pipe.. I've already installed the drainage field as pic and this includes a vent pipe on plot boudary at the lowest point. There will also be a vent pipe on main soil stack to house. So my question is do I also need to attach a vent pipe to the Septic Tank? Or is there a brand of tank that will allow airflow through the tank using my existing vents? Max occupancy will be 8 people for christmas etc. but regularly there will only be 2 people. I think the recommended tank size would be around 3750 - 4000 litres and it needs to be a low profile type to minimise excavation as site is on shale with limited topsoil. Any recommendations on which brand is most suitable would be much appreciated.
  8. Thanks guys very helpful as always.
  9. Ah this could be an idea. I already reached out to the Italian manufacturer in the link posted by Dan F but they directed me back to a UK distributor so I'm still looking at the crazy prices usually quoted in UK. So how do you find an Italian retailer willing to ship overseas? Just realised I may have misunderstood the thread. I had assumed you got best price going direct to Italy but maybe it was more about negotiating best price for supply through UK distributors based on knowledge of Italian supply market.
  10. Single phase supply has already been installed from the transformer to plot boundary and terminated in a temporary cabinet with meter. I chose not to request a 3 phase transformer based mainly on DNO advice that I wouldn't need it and its expensive. So plan is to run a new cable up to this temporary supply point from a new permanent cabinet and meter in the new house and DNO will then join cables and remove the temporary connection. My question is about how to future proof the new cable I will lay from the house to the temporary cabinet which will end up covered over by final finishes for driveway etc. Is there a way I can run a new cable that could be turned into a 3 phase supply in the future if my demand requires (and a new transformer etc.) but for now will only offer a single phase connection? My assumption is to lay a 4 core cable but only use a single core for now but maybe the DNO would not allow this? If so maybe I need to lay 2 cables a 2 core for use now and an additional 4 core just in case for future use?
  11. I plan to use the ASHP as a cooling unit in summer but this would only cover the ground floor. I currently don't plan to provide UFH or rads to the first floor bedrooms and have been exploring options to provide for additional heating/cooling throigh the MVHR system. . One possibility is to use a Mitsubishi GUG MVHR unit that offers both heating and cooling if required. This prompted the question about peak load to supply this unit and ASHP. KW reminder noted!
  12. Hi guys, need a bot of guidance. I've already had a new supply laid to building plot and this required a new pole mounted transformer. Advice from the local networks team was that a single phase 100A supply should meet my needs and in any case they advised a 3 phase transformer would be very expensive. However with the list of things I may need to power growing all the time I'm thinking this may have been a bad decision. List currently looks like: 12Kw ASHP 8Kw AirCon Unit 2 x Car Charging points HIgh power Induction Hob, Solar PV Plus usual stuff for a 4 bed house. The supply is currently terminated close to plot boundary in a temporary cabinet for supply during building works. It will eventually be connected to new cable direct to the house main board. As a minimum id like to run the right sort of cable that could take a 3 phase supply in future. I think this is a 4 core cable? Are there any other options ( run 2 x cables maybe) to increase the available supply without having to upgrade to a new 3 phase transformer? Any advice welcome.
  13. Thanks this is good to know. I was worried this might create a problem with airlocks but i guess not. Much simpler solution and I can stick to caberdeck throughout. A related question. As I plan to put engineered timber boards over the caberdeck/UFH will this need to be glued down or can it just sit on the caberdeck? Maybe with a VCL layer?
  14. Yes the installation detail shows you need to install the spreader plates as well before installing the pipes.
  15. Looking for guidance on mixing floor materials. New house will include a habitable space above the garage that includes a bathroom, kitchen and living space. Headroom is limited so trying to minimise the floor build-up onto the web joists. I've settled on electric UFH for the bathroom (which will also have a towel rail) but need to connect the living area into the ASHP with UFH ( as electric would be too expensive as the primary source of heat. Because of the web joists I understand I cant use the spreader plates under the joists (due to return bends needing to be notched into the joist) and i probably don't have enough headroom to add something on top of the 22mm Caberdeck flooring (glued and screwed to joists). Prowarm (and maybe others) offer a 22mm T&G chipboard floor that is pregrooved for 16mm UFH pipes which seems to offer a hybrid type solution. So my question is could you mix the two flooring systems with Casberdeck under the Bathroom & Kitchen and Prowarm chipboard under the living space? Any advice much appreciated.
