  • H4H Fabrication Details

    Hot water-tank and shower unit.

    Also some metal fabrication details below,


      Note: We originally intended to use brazing when fabricating the water-tank and shower/wash-basin taps and feeds. We now think this is unnecessary because it will be almost impossible for the tank to run dry. So soldering is probably OK.

    Note that you need to use the galvanised pop-rivets, not the aluminium kind, since you will need to solder over these to make the units water-tight.

    Safety:

    The hot-water tank probably has more of a potential for accidents than any of the other components. Normally a water heater can be set to have an automatic temperature limit so that it is almost impossible for someone to be scalded under a shower.

    This temperature control is not possible with this low-cost, simple water-heating approach, however we maintain that the use of a brass garden tap as the main controller of the shower means that it is impossible for the user not to notice that the water has been overheated to the point of danger. You can't turn the shower on without first detecting how hot the water is going to be.

    There are some other precautionary safety aspects to the design:

    • The tap's water entry point is well above the tank's base, so that if a hose becomes severed or accidentally dislodged the water in the tank can never siphon out to the point where it wouldn't be noticed.
    • The entry point of the water flowing through the stop-cock to the basin, is close to the top of the tank; much higher than the stop-cock itself. As with the point above, this makes it impossible for the stop-cock to be accidentally left on, and then for most of the water in the tank to siphon out. The water level can only drop to the point at which it enters the feed-pipe, not down to the stop-cock level.
