Replaced a bunch of halogen lights with LEDs today — or rather, I paid a guy to do it. Some had burned out and another two had been half eaten by possums (mine oldest enemy).
Been a few repairs to effect around here recently. It's been a decade since we renovated and the years have worked their magic.
The solar hot water system turned itself into a luke warm water system a few weeks back, in deepest winter, occasioning a medieval performance every night in which I boiled great pots of water and hauled them the length of the house to pour into the tub.
I thought the whole system might be cactus but the solar wizards we eventually got in said, nah, it was just a tempering valve. Apparently the system was still heating the water to a dangerously high temperature every day, even in winter, but the little valve that mixes in cold before sending it to the tap had failed safe, and so we were getting a geyser of cold with a trickle of hot.
It was a quick and relatively cheap repair, a couple of hundred bucks which, compared to hauling those big soup pots from the stove top, I thought to be a pretty fair deal.
It still amazes me that we can get all of our hot water from the sun. It saves a heap of money and feels a little bit like getting away with something.
Next year when I've got a few more books out I'm gonna look at throwing some more PV units up there to generate extra power. It makes a massive difference to the bills.
After that, a battery system I reckon. And proximity fused sentinel pods for securing the perimeter against zombies.
