  1. I've had two quotes from different heating companies and they have recommended these two: Hitachi Yutaki S80 16kW - high temp with rads upstairs COP 4.57 Energy class A++ or Daikin Altherma - low temp with UFH upstairs COP 4.20 (I think) What are people's thoughts on these two and which one is better/newer/more efficient?
  2. I can't get it closer together as the garden is extremely narrow so it would take up the whole patio so it makes more sense to put at the very rear of the narrow garden. Have neighbours either side and behind the rear of the garden so it's a tricky one with only one solution which is a split system. My gut keeps telling me to go for the LG Therma V R32 but i just had another quote and they suggested the Hitachi Yutaki S80 again. But the 16 kW unit which makes a lot more sense for me. I'm not sure of how it does this, it doesn't detail it in the brochure. Hitachi High Temp Heating and DHW Install Pack.pdf
  3. 64 power 50 pressure according to Hitachi brochure
  4. Anyone had a Hitachi S80 installed as their air source heat pump? My energy consultant is now recommending a nominal 14Kw (max 16.7Kw) unit as my SAP calcs suggest I will require 15.7Kw to heat my property and hot water. The unit is approx 25m from the property and then anotehr 15m to where the boiler room is to be located so running a good 40m worth of air con pipework both externally and internally. Apparently the S80 High Temp heat pump can run upto 75+m. And what about noise for this particular unit? It's a double fan so I'm guessing it will be quite noisy compared to others? If I've found the correct unit online it states about 65 dBa for the outdoor unit. that seemed pretty high.
  5. Has anyone ever heard of this brand of air source heat pump? They look a little bit like a Darlick compared to other units. I cannot find any reviews anywhere online but one of my heating/plumbing quotes has really pushed to use this brand and on paper it sounds good. Anyone had any experience?
  6. For two oak king trusses to be installed (that i already have on site) approx 7-8m in length each. What would one expect to pay for the installation? Assuming it's a 3 day job and would require the necessary genie lift to raise them into place etc.
  7. @MG-Wales As these are not birdmouthed as suggested would I still need the truss clips? And does the top horizontal timber that the rafters are sat on needing to be double timber or is the single enough? All I want to make sure is just that everything is safe, secure and would more than pass any building control inspection. I'd rather go over the top and feel better about it.
  8. 3 Phase is already in the property so I am just wondering if there would be any extra benefits by having a specific 3 phase heat pump? 16 Kw is what size heat pump i've been told i would need to service the property. I do have solar PV panels freshly installed and do intend to future proof myself by having an EV charging station installed.
  9. Yes this is for external use but i don't like the bulky standard outdoor sockets that would stick right out on the brick wall surface. @Roundtuit That makes a lot of sense, at least that would get rid of some that bulk. I don't mind them sticking out a little bit.
  10. Is there such a product that is basically a double socket that fits perfectly into a brick slot? So the box is flush rather that sticking out?
  11. Are there any benefits or disadvantages of these two types of ASHP?
  12. Yes don't get me started on the nails through the felt @Marvin What are those brackets called in the second image of yours?
  13. Hi, I have parted companies with my contractor who has left me in a bit of position to take over the project and I wanted to check with the experience of people on this forum what their thoughts were on how my timber frame is connected and if it would pass building control regulations for example. Where the timber rafters connect to the structural load bearing stud wall, should there be any kind of metal plate connector tying them in together? I attach a photo to show what I mean. Is there anything else in the photo that looks incorrect? The plywood you see at the back is the box gutter.
