    size of battery needed for my solar panel

    Why not? A brief discharge of 20amps, is well within the capability of a low capacity lead-acid battery. Where the 100/120ah came from, I have no idea. Both of mine ramp the burn down, to a minimum, once temperature is achieved, until shut down. The shut-down, is a controlled process, to...

    Isolator on extractor fan

    Which would be a sledgehammer... Spot on! Extract the over-moist air, directly at source, put rules in place, no need for a dehumidifier. We had both issues - too dry air, yet in some areas, it was still humid enough to grow mould - plus high heating bills, from running the temperatures...

    Isolator on extractor fan

    If the air, is warmer than the walls, and the air is humid enough, it will condense out on the walls, and trigger mould. Even in winter, if the doors and windows are opened wide, with no heating, there will be no mould formed, providing the roof is sound. Warm interior, with cold walls, plus...

    Isolator on extractor fan

    You maybe need to read some of the posts in the General forum, where there are lots of questions about mould, other than in bathrooms.

    Isolator on extractor fan

    Back in the mid-80's we had central heating installed, but nothing effective done about ventilation. It was warm, but moist, we had mould. Simply adding proper ventilation, sorted the mould issues.

    Are you not doing exactly the same John, is it not one of your well known traits in any discussion?

    Isolator on extractor fan

    In the water supply industry, I was familiar with, control cabinets, were simply fitted with heaters in the bottom of the cabinet. Either the usual tube heater, or the large, gold resistor type. Fans were simply not needed in the cabinets, until electronics came along, and big triacs for...

    size of battery needed for my solar panel

    10 to 20 amps, but the time is variable. It depends upon how quickly the stable burn takes to properly establish itself. The start is closely monitored, by the control system. The tip of the glow plug, glows red-hot, to ignite the fuel, while-ever it is powered. Once a proper burn is...

    size of battery needed for my solar panel

    Were you not taught any simple sums, at school, or did you take that day off? 0.42 x 76 = 31.92amp hour. In theory, 100%, after which discharge, a new battery would be needed, because that one would be wrecked.

    Isolator on extractor fan

    As I keep repeating, we have no mould issue here. We did have a very slight issue, with a tiny amount in the ceiling corner, until a few years ago, but I addressed that. It's obvious now, what the issue was.... I had installed a bathroom wall fan, PIR, and humidity sensor, with a timer - but I...

    Weird Coincidences

    I cannot find a website which states where. The Egyptians were using it, it seems.

    Isolator on extractor fan

    I was trying to point out, that the extraction of moist air, is more important than warmth in the fabric.

    size of battery needed for my solar panel

    Too many pointless questions.... However... As already said.The Webasto, in the car, runs from the car battery. I charge nothing from solar. The workshop heater, now runs on an adapted PC PSU, no battery involved. Yes, that ran absolutely fine from the 32amp, why would it not, but you cannot...

    Please identify the screwdriver type for this screw?

    It appears to be, a poor quality, stamped out philips screw.

    Please identify the screwdriver type for this screw?

    Nearly. 8 total points, a cross, plus 4 extra points = PZ 4 total points, a cross = philips. 4 total points, a cross, plus a dot = JIS.

    Concealed joints again!

    I've never used gel, always resin compound, some quite large cable, some quite small, mains signal cables, but always crimped, or soldered.

    What have you been doing today?

    I did that, just the snore, during an advanced test once, and deliberately. Should have seen the instructor's face ;)

    Dead Dewalt Battery Revivial

    They are wired together, in series, to give to 20v. You can still check the voltage without disconnecting anything, putting your probes across the top and base of each cell in turn.

    Dead Dewalt Battery Revivial

    Whilst you have it in bits, check the voltage, across each cell. They should show 3.7 to 4.3 -ish.

    He, along with certain others on here, are mentally sick, desperately sad, and envious individuals. Desperate, to bring absolutely everyone, down to their own levels.
