Good Morning All,

Woke up at 0345 this morning, my body is still swinging around to UK time!!!

A few photo's of the CTC Gsi 12 installation that occurred during my last leave.

The first is a pretty boring picture of the field after the 2 x 400metre ground loops were installed.



The 2-way manifold with pipes to the house not yet connected.



Solar ET framing being constructed.



Immersun T1060 under crude testing.



Immersun T1070 on the end of some 45metres of CAT5 cabling to the sensor.



Part way through installation of the heat pump and heat store.



Another install picture.



and another.



CTC Solar Controller.



Solar ET charging kit.



CTC Control Box in situ.



View inside CTC Control Box - lots of money for empty space?



Stelrad K3 radiator in Utility Room.



Pit prop as access hole to get the old hot water cylinder out is created and extended to fit a new trapdoor.



Photo of installed 59 solar ET tubes.



It took 4 top-ups of the ground loop before the air pockets were eliminated which had both the installers and myself worried but it has been OK now for over 2 months.

As I think I may have said elsewhere the system hasn't been optimally set-up until yesterday as far as the ET side is concerned as the default factory setting for the External Heat Source (EHS) or heat store is 70 degrees C i.e. the system would only make use of the heat in the heat store if it reached that temperature. Unfortunately when the system was set-up the maximum allowable temperature was 70 degrees with an automatic cooling down taking over above that. Now that I have reset this to 30 degrees the heat pump circulated the radiator water through the heat store and took it down from 58 to 32 degrees with some intermittent low level heat being provided via the ET system during the day which maxed out at only 47 degrees due not much sun!!. At least the system absorbed that energy now that heat is being extracted as intended.

As I finish typing this it is 0630 and the sun is shining and there are blue skies although I'm sure the wx forecast was for showers.........

Regards

Richard

Good Afternoon,

Well its been grey and showery here today yet as can be seen from the photo below the solar EWT panels are putting some energy into the EHS.



At the same time and although the heating isn't actually 'on' at the moment the system is circulating low temperature background heating and actually sourcing it from the EHS as this photo shows.

Good Morning All,

A quick photo after I attached a battery to the Lorentz tracker yesterday having left it pointing south all winter. I'll find out today if it will behave itself!! It had developed a habit of tracking to the east in the morning and then staying there, I suspect it may be wear in the actuator drive mechanism.

Yesterday was a good day from an energy gathering point of view. Between the solar ET and the solar PV (via the Immersun) the heat store went up to 60 degrees C and the energy was used overnight via the radiators and the store is down to 34 degrees this morning.



Regards

Richard

Tigger,

I'll see what I can do one day when I'm at home and get myself sufficiently organised.

Right now I'm chuffed that it is working OK so far today. I'm beginning to think it may have been more a battery orientated issue. I put a new old (desulphated) battery on it from the old Polo yesterday. This is backed up by a LM2576HVT based voltage supply set to 13.7V.

The initial indications were good (after the battery was attached) as it went through the 'normal' start up procedure which sees it move all the way to the east and then through a full swing to the west and then back in steps to the mid-position. It then has a 'think' and did start tracking west towards the sun before settling at due south overnight.

When I got up this morning it was heading fully east and, as I type this, it is heading due south. Fingers crossed.

Yesterday the heat store got to 59 degrees and overnight the radiators extracted heat down to 34 degrees and now the heat store is back up to 51 degrees as a result of both the solar ET and Immersun diversion. I'm away from the house shortly (heading in to Aberdeen to go kayaking!!) but if the sun continues I'm hopeful the heat store will get up over 60 degrees as I've altered the heat pump settings to allow it.

We are intending to fit a Mira Adept Eco BIV mixer shower in place of the existing Mira Elite 2. The latter was the only viable option 15 years ago given we were on a spring fed supply with a maximum supply pressure of 1.3bar (on a good day). The Adept will utilise hot water from the heat pump/ heat store rather than using 10.2kW of imported electricity so makes obvious sense and was a part of the decision to go down this route in the first place.

Regards

+1 for a timelapse of the tracker in action over the day.
Looks a great set-up you've got there.
Thinking of a wind turbine next perhaps?

Good Evening All,

Things were going quite well this morning. Again I wasn't expecting quite so much sun so things were cooking nicely. The first picture is the Heat Pump overview (note solar panel temps)-



This screen shows the EHS charging and up to 58 degrees C -



This screen shows the DHW being heated from the EHS -



This picture shows the Immersun was contributing as well -



What can't be shown is that about two minutes after the last picture was taken a whole load of grey clouds came over and the whole process kind of 'died a death' which is the way of solar energy I guess. The real pain was that with the system having decided to heat the domestic hot water (I believe because it saw that the heat store had reached 58 degrees) and insufficient heat being sunk into the EHS it decided to start the brine pump and compressor to finish the job.

dan_b - I'd love to get a wind turbine in but we are in too sheltered a spot. I have all the necessary parts for Hugh Piggott design (save the blades). We also have a small burn running down one side of the property but need to gain ownership of an adjacent piece of land to utilise it for a micro hydro turbine.

I'm currently looking at just how low cost I can make an add-on solar PV system to charge a battery bank as being non-FIT I can buy everything second hand.

Regards

Richard

This is fantastic! Those ET tubes are really cranking even in less than ideal conditions.
Well done, keep the updates coming.

Good Afternoon All,

For those of you not familiar with how an 1859 Aberdeenshire farmhouse was constructed the following pictures will provide some insight. This is the Dining Room after the bulk of the lath and plaster has come out. The first photo shows the size of the gap between the floorboards and the wall, it is at least 2" most of the way around -



You have the normal lath and plaster set-up then nailed to battens so what 3/4" of material between the room and whatever extreme of temperature exists externally as the space under the floorboards is vented to the outside and this directs the cold air up to the floor above -



The fibreglass was inserted by me when the heating was upgraded 15 years ago to act as a kind of draughtproofing. Essentially underfloor, behind the walls and the ceiling space were directly connected to the external air.

We have ripped most of the upstairs apart and shoved 90mm Celotex between rafters and then overlaid with another 50mm with all vaertical walls using 50mm Celotex. There is still some work to complete. The Utility Room and the kitchen has been done. The kitchen is the only space so far with UFH.

We've retained the original skirting either to re-use or as a pattern -



This picture shows a part of the cornice, we've retained sample but don't think an exact copy is available although it could be replicated at a mere 130 a metre!!!!



The existing K2.0700.0800 radiators on their way out. When the heating system was installed we had to get the installers back in and they had to replace both the radiators in this room, both radiators in the Living Room and the radiators in both front bedrooms as the originals simply weren't up to the job. Given they were local installers I was a bit surprised that they had underestimated the actual heat losses.-
 


I'm almost at the point of starting to remove the flooring ahead of the builders coming in and laying a base to lay the Celotex on prior to the plumbers coming in to install the UFH.

What fun. All this needs doing as part of reducing the amount of work the heat pump has to do an thus have it operating in the most efficient range.

Regards

Richard

Good Afternoon Again,

Less sun today meaning a lower level of activity. Still the first picture shows the overview again:-



The EHS being 'charged' -



The EHS 'active' on providing energy to the heating circuit (HS) -



and a 'Smiley' Immersun -



Again shortly after the pictures were taken the heat pump decided to 'dump' the EHS and started the brine pump/ compressor. It has since stopped the compressor again and the EHS is currently providing heat to the radiators. It's kind of grey'ish here at 1742 and the solar ET is putting out 52 degrees and the EHS is at 49 degrees so still putting some heat in to the EHS only about 0.1kW.

Regards

Richard

Good Evening All,

I'm just about done stripping out the Dining Room -



The insulation arrived today -



and as the weather people said it snowed today -



The sub-base is now due to be laid on Friday.

Good Morning All,

This probably isn't the best place to post this but as my Lorentz tracker has been mentioned here then the issues I've been having with it might as well be detailed here.

I came home on the 13th and decided to power up the tracker again having had problems last leave with it and deciding to just leave it pointing south. As mentioned above I thought the problems might be battery related and yesterday confirmed it was.

The tracker was fine for the first two days and then it started playing up. Yesterday I tried three times to 'reboot' it i.e. disconnect power and then re-connect an push the 'Manual' button. No joy it just didn't want to play. Attach one of my trusty old Gunson's chargers to said battery and it started up and did its thing.
It parked itself overnight i.e. pointed south and this lunchtime it is performing as it should.

Clearly the mains powered power supply I've attached is being 'pulled' down by the state of the battery.

I need to look at a new battery or need to use the existing power supply to charge a big gathering of capacitors (I have plenty available)Huh I need to resolve this powering of the actuator issue for once and for all as I can't leave a battery charger out there 24/7.

There is wear in the actuator as there is wobble in the frame when you shake it but given how much weight this actuator has had to move in the last 8 1/2 years that is hardly surprising. The Satellite Superstore do replacement Superjacks at around 130 should it become necessary.

The thing that gets me is that Lorentz supply a fart arse 5AHr gel cell within the plastic control box, realistically this wouldn't have lasted very long, thinking back it didn't.

Regards

Richard
