Hello,
1. RO is currently running at about 50/60% waste - is there any system that greatly reduces this or even eliminates this?
2. Hot water question.. Is it 100% necessary in winter or can you do without it? If you can do without it then how? Reason being I have just gone WFP over the last few months so spent quite a bit of money, and now winter is approaching im starting to think ill have to spend even more!
Thanks
