    16mm SWA

    Spoke to my tame sparky today. He’s recommending three core 16mm SWA plus the earth rod. I think I followed his technical description in that the earth would be connected at the supply end only to provide earth protection to the cable but then the rod for earthing at the load side.

    OK, so I went down first thing this morning and took another set of readings. In that time only two things had any demand on the Sunamps: 1 x 5 minute shower. Aprox 2 hours of the kitchen hot water loop (c12m of 15MM pipe all very well lagged) Unit 1: 4.5 Unit 2: 4 That's clearly double what my previous logs have shown for that level of usage. I think all I'm really doing is proving what we already know; the controller (and measurement) system is less than perfect!

    Sorry I assumed this was being hand cut to bespoke specifications. Hadn’t realised you were cheating with a flat pack 😉😂

    16mm SWA

    Thanks guys useful info. It will certainly pick up considerable speed rolling down my garden😀

    Thats not my experience at all. The units are always warm to the touch and when charged the supply pipework is roasting hot between the two units. Ive assumed that’s because the kitchen hot water circulator pump (which switches on when the kitchen light comes on) and other demand keeps things hot?

    16mm SWA

    Hi All So I’m busy planning the final aspects of the landscaping plan. I need to get power to the bottom of the plot for a garden room /gym. It’s not going in straight away but now is the only chance to get services down there due to other aspects of the landscaping. The run is 100m so my calcs show that I need 10mm SWA but I’d rather put 16mm in as there is a chance a hot tub might go in. Whats worrying me me is just how difficult is 16mm to handle manually? It will just get dumped on site on a pallet. Moving it on strops with the digger will be easy enough but there ain’t no way it’s going to roll off the drum Has anyone had the pleasure of manhandling 16mm SWA?

    Yes. They flicked on and off pretty much straight away.

    Following on from the above I'm going to revert to keeping a detailed log of demand and recording daily meter readings. Since the above readings I've taken one shower and there has been no other demand save for the hot water loop to the kitchen which has run for a few hours. Its the only way I can get a sense of what is going on. Its OK though I've got nothing else better to do

    Sorry, I'm forever typing that the wrong way round and getting confused! My units are now set to 50% like yours. So much miss-information from Sunamp in the early stages has left my brain addled! I've edited my post.

    So they both consumed electricity and stopped accepting charge after my bounce as follows: (readings from the meters) Unit 1: 3kwh Unit 2: 6kwh This suggests that Unit 1 was at 75% and Unit 2 at 50% (Mine are 12kwh units). They should be demanding charge at c50%. Whats really getting me to scratch my head is the units were cool, the pipework was cool, the plant room was cool. Clearly they were much more discharged than the figures would suggest. So are my units fully charging partially? There is no way of knowing as you've got no indication of level of charge. Yet again the world of Sunamp leaves you largely in the dark!

    Insulating under cabin floor

    You could actually lay the jablite straight over the top and then screw your floor down to the joists creating an EPS sandwich. The jabfloor stuff has an impressive compression strength.

    Jablite jabfloor? 50 or 70mm is relatively cheap. Available in 2400x1200 sheets for around £14 including VAT. its what I used to insulate my shed and workshop floors and is surprisingly effective.

    Alas no. The only difference I could see from this set to the last was the relay type. These controllers were delivered in December so there is a good chance yours will have later software.

    Jumping back to your thread. My controllers are relatively new (my third set!) and this is the relays in my units:
