EDIT: I’m sure this is quite unnecessary to mention, but do use a header pipe on the hot water cylinder of your solar hot water system so that it’s vented to atmosphere. Be a pity to build a steam bomb rather than a water heater.
Gah!
Another is not to do what a friend of mine did when the HWC started boiling – turn on all the hot taps to cool down cylinder. Waste pipes aren’t built to take boiling water. He had a long and smelly job under the house replacing the melted waste pipes. -

Because almost all solar water heaters lose energy on cold cloudy days, and much of NZ’s land area has those for half the year.
They shouldn't lose energy, any more than a wetback will when the fire's not on -- flow into the heater is controlled by valves.
Consumer points to the high cost of the device as the main reason not to install one.

Disappointingly, Consumer says they're not great. Too costly for too little benefit.

So, I was just talking about why does everybody not have hot-water-heating solar panels and my sister pointed out that our neighbour does. This is apparently what they look like!

solar thermal for hot water production
I remember having some quite acceptable washes under one of those "solar shower" things you can take camping. (essentially a black plastic bladder you fill with water and lay in a sunny spot). Admittedly, that was summer, and one has lower standards when camping, but...

In terms of resource consumption, CSP isn’t too bad (PV is one of the worst) – not sure how effective it would be in NZ except for a few special areas in summer.
Could it ever be feasible for each house to have a thermal-solar system on the roof to heat the hot water?
(thanks for the link)

analysis of the net benefit (or otherwise) of solar power (photovoltaics) in NZ has been done
How does that compare with solar thermal? I'm guessing the storage problem is the same, but are the manufacturing issues any better?

Amberleigh, if your brother was anything like you, he was amazing. Thank you for writing this.
I know a woman who used heroin for many years, and nobody knew. Her family knew something was the matter, but had no idea it was that. She only opened up after she got clean, which she did with almost no support, because people who loved her didn't know.
I'm so sorry for your loss, Amberleigh. And for yours, Rob. I'm sure your brothers would be so proud of you.

in the last paragraph here I’m starting to sound like my anarchist Glaswegian grandfather!
It's OK, we'll notice if you start calling for the imprisonment of all dry-cleaners.

I don't claim to understand how it works, but there is a process for making steel without coke or carbon emissions.
