Onoff

Did you pay by credit card?

Only DeWalt I have is a GIANT router. Beast.

As I say I'll probably take this, the second one back. Can pull the trigger now and nothing. Have to give it a damn good whack to get it to go. Brushe or some other loose connection I guess.

Space rich, cash poor people like me do!

Think bigger, like part of the basement!

A great pity all this. I imagine those who have gone the Sunamp route aren't short of a few quid and are happy to pay for good tech at a slight premium. Couple that with foresight, investing in the long term and looking for self utilisation rather than export. Pity the new SA isn't really maybe aimed at them but the mass market. I'd wonder at less physical sensors maybe to keep the costs down leading to possible localised overheating of the PCM if the PV input is "rushed". The previous "wet" heat transfer system allowed for a more gradual, distributed heating of the PCM without killing it. That there is no quick fix suggests SA are sh!t scared of if they did that they'd have a whole lot of new, peed of customers with completely buggered units. With nothing of worth coming out of them this conjecture will only continue. So...you're all digging out for these grand designs...how big a hole would be needed for a simple, heavily insulated thermal store, heated by whatever means available, to equate to the efficiency of a SA unit? The Yanks seem to do it all the time on their solar sites.

In case you want one of these in the shed?

Just thought he might want local isolation by the machine.

One of these: https://www.screwfix.com/p/jg-speedfit-ug603b-mdpe-copper-adaptor-25mm-x-15mm/25716? Bit of 15mm copper pipe Then one of these: https://www.screwfix.com/p/pegler-washing-machine-valve-15mm-x-/25555? ?

£8 delivery.

Is that for getting the boards to fit i.e. wriggle room? Or expansion?

Imo, a tongue against the wall looks a bit rough. Cut edges much better.

Will probably have one knocking about. I did think the - end looked a bit odd, like a crack in the factory solder where the lead joins the body: Looking closer I'd say that - and should be soldered to both sides of the board. This side, well it might be making contact with the copper track by there's hardly any flow through:

Yep did try. Had the back off. Nothing obvious. No idea on the soldered in battery other than it's yellow and has "70" written on it. At rest the pinouts seem correct. 1&2 are NC and 3&4 are NO with respect to L. Relays are obsolete, Omron G6C-2117P-US-SV. Just poked the reset button under the cover and it's come right. Wonder why, never happened before...battery? I'll slap it back on tonight and setup the times again.

Came downstairs this morning to find the place uncomfortably warm. Downstairs CH had been on all night. The controller seems to be at fault. The LCD display has gone all squiffy and locked. I can press either of the grey buttons and nothing changes: Didn't have time to do anything other than whip it off the wall and tape over the connection plate then leave SWMBO a note. Taken it to work with me so I'll whip the cover off and see if there's a replaceable battery in there. Can't honestly remember if I've ever done this before, vague recollections maybe... I'll also chuck a meter on it and see if the relay has failed and is constantly calling on 4: Still, it's over 20 years old so has done well. Surprised it fails "on" though. This one does downstairs CH and HW. Worst case tonight I swap it out for the same controller above that just does upstairs CH. Was debating renewing with a 3 channel controller maybe, that'll do 2x CH & 1x HW. Any suggestions on a make?

The Titan one on clearance at Screwfix gets reasonable reviews. I was tempted for £50...

...again???

You bought one spare no doubt. A&E trip later is it?

So if you insulate the floor too you bring the insulated pb down tight to it?

Ta. I'm a bit lost. Says it can be used to "correct surface irregularities" which I get. Also to "create a service void". Is mainly to correct a wobbly wall? Then you insulate on top of this?

He means TT, TN-S or TN-C-S earthing.

It's a good 5mm deep probably to the existing grout. Feels deep enough to just clean up and go over?

What's 'gypline frame'? You don't just stick the insulated pb to the inside face of the existing walls? Is there a vcl?

Nothing says "I love you Faye!" like lead poisoning! ?

I know but should I grout it level with the tiles first to "bulk" it out?
