I have a solar evap tube geyser (no element) and gas geyser and want to change from an Induction hob to gas one.Ģ X 5kW Microcare Bi Directional Invertersġ X 60Amp SetSolar MPPT (Believe its also Microcare) Usage currently is between 15 -20 kwh daily, depending on washing, dishwasher use. I am in the planning stage but I have some hardware already, I have a good idea of my daily usage but not really how much hourly, so I got myself an Efergy Engage Hub for the DB and a Sonoff Pow R2 for checking usage on individual devices. Having some idle time for a change I stumbled across the solar idea yet again, been reading topics and trying to match my equipment, checking what other guys have done, what they use etc etc. Does anybody have any experience with this/know much more about it? Is just a bad idea if you plan to drink the water, or will the acidity of the rainwater destroy the pipes pretty quickly? I'll wont be drinking this water, but I don't want to have to replace the pipes after a couple of years. I've heard a few people say that you should not use copper pipe with rainwater as it tends to be acidic and may corrode the pipe. What this means though, is that these fittings (2 toilets and washing machine) would be supplied via their existing copper piping downstream of the "switch over" point. The switch would just be at one location - I don't want to have to drill new holes into the water at all 3 places and have some kind of switch (eg: below the toilet) to manually switch over each one - that would be madness. I should be able to isolate those 3 supply points onto one line such that they can be fed by rainwater, and then switched over to municipal if I don't have any rainwater in the tank. However I'd like to put a couple of toilets and washing machine onto rainwater, but obviously can't guarantee a year-round supply. I've got a rainwater harvesting tank and small pressure-controlled pump which is currently totally independent from my municipal supply. I'm not sure if this is the right place to ask, but I've read some really useful forum threads here about rainwater harvesting, so here's my question:
