would coke work then?

it's not really management, just overcurrent protection and low-voltage switchoff. /my first Dewalt lithium pack was bought dead and cheap in the hope that it wasn't really dead but had a dry joint or similar. Infact the cells has just turned off and giving each 3v for a few seconds woke'em up and it then charged fine...
-
0v often just means "turned off" bt the cells own internal BMS rather than dead/flat. It needs to see volts to waken up, per @Miek above. If the whole group is @ 3.2v , what charge rate are you at? How much charge has actually gone in?
-
why not box and tile the whole thing then if it's just for appearance-?

can you fabricate a ring of something to fill the gap? -

fans need to be a close fit in their housing otherwise efficiency is reduced, the air basically recirculates. -
our guys did neither of those.

Why would the TF company need mains power?

certainly L&Cs take on hybrid is to switch from ASHP to the other boiler when ambient temp crosses a set point, it's configurable with DIP switches to temps betwen +5 and -5C. Presumably they reckon that the COP loss plus defrost cycling means the alternative fuel is cheaper in those circumstances.

Totally clueless and overwhelmed.......help!

You know, I've just re-read your story and brief and it's amazing just how similar it is to ours. And this is what *we* ended up with. dorm093-350-Miller-NI-A.01.pdf dorm093-350-Miller-NI-A.02.pdf- 39 replies

Some heatpumps have built-in control for the boiler using similar strategy. The Peak/ Lailey and Coates unit for example.

You'll need to get a design SAP done for Building Control so that'll be a useful bit of modelling.

thee are some good "book plans" out there to get you started. We used this guy http://www.irish-house-plans.ie/index.html Shaun is really good, he totally re-drew one of his base designs to suit our needs. he's got a wide range of examples and you might be able to find portions of some that suit.- 39 replies

Sewer on Neighbours Land - Charge to Connect
dpmiller replied to NewToAllOfThis's topic in Waste & Sewerage
Does the neighbour actually *own* the land? Can you check whether the properties are freehold or leasehold? -
The end of the beginning
dpmiller commented on dnb's blog entry in Building in a woodland on the Isle of Wight
Looks good. Those blocks look very like the Quinnlites we used and similarly we've had no issue- expressnails, Hiltis, screws all have gone in firmly without incident. -
But as inverters are current sources, trying to drive into what is basically an open circuit and minimal load would likely have the voltage swinging wildly. The mains supply isn't just for frequency control...
-
why not just widen the current path into a driveway?
