I'm with @dpmiller. Please give us a few more photos - some a bit further away so we can understand what is being shown. Otherwise like you its a bit confusing. The first photo seems to show the glass sealed unit with the beading that holds the glass in the frame removed. Is that right?

Hi @JohnMo Yes a lot of small adjustments in construction and as I see it: UFH so not bad really. Only thing that really adds to the heating is a wall of glass To achieve an air temperature of say 21C at about 1.5 meters from the floor (typically the height of thermostat height) in a room with 3.6m ceilings you need to heat the top air about 25% higher... so increased running costs No difference to any other just plan ahead. True, but more/larger MVHR units and ductwork requiring more air to be circulated so really both installation and running cost increase. The biggest cost is the running costs per year, every year, but it's personal choice. They do look lovely in the summer...

Hi @Benpointer The old function versus form challenge! Looks great! However, harder to paint, harder to dust, harder to dress windows, harder to sort out acoustics, harder to heat, harder to cool, harder to light, harder to clean windows, harder to vent, harder to build, but looks great. (or replace the word harder with more costly) As we are some of the poor of the parish, wo chose not to vault any rooms not only from build cost but also running costs, however, you pays your money, you takes your choice. Most people buy on looks anyway, and if its your already home, it may well be worth choosing. Good luck M

Solic immersion Heater controller Model AF2.1 fixed following following @eugen's advice. Replaced C1 capacitor that cost about 60p and saved at least £150 by not replacing it. If anyone has a picture of the insides of the Solic 200 wired controller please would you upload. I think it will be basically the same as the Solic AF2.1. I will put the method of replacing the C1 capacitor with pictures, in a blog in the next few weeks.

I Think its something to do with the software...

Contacted Coolenergy. Who were very helpful and as I had a reasonable understanding of the whole system we were able to go through things on the phone. Problem seemed to be related to hot water heating function as since emailing Coolenergy I had set the Carel to heating and it had started heating, but when turned on to hot water - no compressor or fan. Changing various setting as instructed changed the fan speed from low to normal and the hot water started working again.. This may have been a blip of some sort. However, I will do some tests over the next few days.... Here's pictures of the Carel programmer:

Hi @ProDave "Self builder in the Highlands. See my build blog here http://www.willowburn.net Heading for retirement and planning our "adventure before dementia""🤣🤣🤣🤣 Will do.

Hi @JohnMo Yes. When turning back on alarm message shows power was off so reset. Emailed Cool energy with problem...

Inspected ASHP. No indication of any outside problems: Fan free to turn. Pressure levels hi and low at 0.9barish. No obstructions to the grills. Inside: No alarm codes.

We have a Cool energy ASHP CE-iVT9 which has stopped working. It has a Carel control system and has been working fine since July 2021. The symptoms are: Power on and Carel active Hot water and or Heating demand can be chosen but no heat delivered. Heating on with demand: Carel indicates heating chosen, temperature 10 degrees below set temperature, pump on, no fan and no compressor. What checks can I make to identify the problem? I am going to inspect ASHP now in case of freezing?? M

What's this! Today's challange!! Hi @Russdl Yup @Russell griffiths Idea will do it, however sometimes multi grips not big enough so another choice:

Hi @Dillsue Of course your right. What sort of price are they to purchase for each panel?? It maybe something for us in the future. Am I right that they will protect the rest of the string if one of the panels is shaded? Another thought. can I use different rated Voltage/Amperage panels (I am looking at a very close range)? Every day is a school day for me... Thanks M

You know more than me.. we obtained approval for our 6kW inverter so all's fine for us. As I understand it G100 limits exportation: No export allowed (G100 applies) – this means all electricity produced by the embedded generation must be utilised on the premises. It may be that a different type of inverter or controls are required... you tell me. M

Hi @richard_scotland Bear in mind that it is quite difficult to mix PV panels. Having investigated this when considering increasing the amount of panels for our home a couple of things came to light. If you add PV panels to an existing system it's complicated to do unless the panels are exactly the same as the existing (not just the same manufacturer but voltage and amperage) as 1 different panel added to a string would effect the output from all the panels. Unless you install a special system, if you have some panels shaded or facing a different direction from the others on the same string, the outputs of all the panels on the same string will be effected. Best of luck. M

Our DNO would only use the upper export limit of the Inverter in their calculation. Their opinion was that lower adjusted exporting limits on Inverters could be inadvertently altered and so certainty of requirements being followed.
