ReNew Issue 135
Water saving special
This issue of ReNew explores where households can save water, inside and out. We look at efficient and effective use of water for gardens, including drip irrigation, wicking beds and using stormwater via rain gardens. Our mini guide is on waterless toilets. This issue also updates our heating buyers guide, with an in-depth look at hydronics and heat pumps (reverse-cycle air conditioners which can be used for efficient space heating). We also bring you the latest on what’s available in all-in-one battery systems and where the market is heading, and we examine the sustainability benefits of solar and solar + battery systems. Plus lots more: a DIY on double glazing, a mini hydronic system, a wind-farm round-up, a collaboration to power an Indigenous ranger station and nine water saving book reviews.
Issue 135 is hot off the press and full of advice for your sustainable home this summer. As always, ReNew comes overflowing with articles to satisfy both the technically and the not-so-technically minded. Regardless of whether your interest is finding out which heating system to buy, adding batteries to solar, saving water indoors and out or DIY projects such as double glazing or a mini hydronic system, there is something for everyone in this issue.
ReNew 135 has ‘water saving’ as its focus. Inside you’ll find:
