We usually go to Kalcan, hire Jeep and go into the hinterland north. Great fun provided you stick to the less travelled roads. Anyway looking forward to hearing about your project and ideas there is so much, so many, here on ASHP / heating / cooling / DHW / Solar Thermal / PV... to discuss and share ideas.
-
Yes should have used that. We love Türkiye but have not been there for 10 years now, various reasons, but will be going back.
-
Interestingly the converse of my experience of Turkey where you need the cooling on all night!

It's a bank holiday so we can work unhindered although I just noticed our local BM delivering stuff to a site up the road! Sunny here also, but raining tomorrow, so think I will have a day doing something else, maybe read an improving book- EG a treatise on the finer points of ASHP standby power draw.

Ecodan standby power consumption

Nope foot-pound/seconds, to be frank I dredged it up from my far distant memory so I could be well wrong but based on 1 kg⋅m2⋅s−3. -

Don't worry the government are about to launch a consultation about bringing back imperial units. That will mean talking about, BTU, foot pound / seconds & horsepower (and have to deal with the fact that HP differs by country), instead of Joules, and Watts. -
Yes - think about it, you are reducing the effective depth at the point where you want the max strength. You might discuss using a deeper flat hanger and putting a sloping wooden insert in the bottom to rest the rafter on with your SE.

It's not over until it's over so hope for the best and prepare for the worst by finding a good planning consultant in case you need to appeal.

Ecodan standby power consumption
MikeSharp01 replied to LA3222's topic in Air Source Heat Pumps (ASHP)
Looks like nothing much has changed in 9 years then - this is close to obscene in the sense that we are all being encouraged to fit these devices for 'eco' reasons and yet the devices themselves are not so eco as all that. Looks like the scroll compressor driven units do not exhibit this effect so that's the way to go + asking what the standby current is for a unit you want to start instantly. -

It is odd given that you could use something like the EPS32 mini in a light sleep to watch over it and that would cost about 3p per year to run and be ready for action on reciept of a prod via wifi, Bluetooth, it's RTC or one of its pins. -
Very tidy, if you don't count the 45 degree link on the veroboard😁, where would we be without veroboard I wonder?

Thought I would dig about a bit more on this topic - from an academic point of view at least. Found this link (https://learn.openenergymonitor.org/pv-diversion/introduction/choosing-an-energy-diverter.md) very useful in setting out the landscape rather well. I found very little actual academic research on the topic but there are more commercial devices out there than I had suspected although few give away much about the technology they use.

perhaps adds to it for some though!

Should I be sorry to here that - if so I am?

I think I am still not clear why your current trace is the shape it is in terms of nuances (get the switched mode thing I think) EG the tiny burble just right of the current peak on the down slope. I can see that you are looking to handle things cycle by cycle and I am wondering given that the next cycle can be either import or export, perhaps randomly - might be fun to find the likelihood of each type of cycle following on under differing circumstances (just a few), just how quickly a load needs to respond, at both ends of the cycle, to be sure you do not end up in: a) a fight between appliances to use power they thought was there (they were told so) but isn't because another load got there first - too many pile in and b) a ringing loop that actually causes loads to switch on/off exactly out of synch with when you want them to. The single dump load probably solves the first, assuming you can overcome the issues @ProDave highlights, but how much of a potential export cycle will you get assuming you can send the message once you are sure the cycle would otherwise be an export cycle and then not leave it on for the next cycle until you are sure this is going to be an export cycle ad nauseam. All that while keeping track of the 3600 J / 1 Wh point. Fascinating exercise. PS I think this crossed with your post - I think I get it now - perhaps.

Yes because it encourages development, by focusing our natural curiosity, in other directions leaving these roads un-travelled but among the known knowns so that we when we all have an automatic heart re-starter we can start playing again on this, now dusty, road.
-
Tend to agree but to be a little fairer HMG need to do the leadership thing and explain to the builders why this is a good thing so they can in turn explain to clients why it will cost more while at the same time ensuring there are incentives to train in how to deliver the new way forward. Sadly it looks like this is another surface move without anything underneath.

When putting up stick built you need something to keep the walls upright while you build. We used the scaffolding to do that with some internal bracing. I made some adjustable clamps so I could get it dead right by strapping the digital level to the stud and then listening for the upright tone while adjusting my little clamps.

Cable in or under slab for kitchen island
MikeSharp01 replied to Chanmenie's topic in Electrics - Kitchen & Bathroom
We used 4 ducts (75mm) 1 for gas, 1 for electric, 1 for water and 1 for comms. Put the the whole lot under the slab and up through the dpc with custom seals I made. -
Rookies diving into the passive house deep end
MikeSharp01 replied to Jake Smith's topic in Introduce Yourself
Ours, without PH build experiance, was very bright and willing to learn and if you think about it every Architect will have made their first PH without any experiance. Also we found that the PH experienced architects we interviewed were too cautious and so had, in our view and certainly not to denigrate them, somewhat limited horizons as they automatically kept their ideas in the PH envelope and so did not offer anything really 'out there' which we thought our design needed to be. -

That is not a great thought to hit you on a Saturday morning - but I have to praise your fortitude in staying away from it for 36 years. I manage a chocolate free lent each year and that is about all my abstinence tenacity will take.
