Newbie but not new to reptile keeping

I've looked at reverse osmosis machines but I'm not very handy so wouldn't trust myself plumbing it in

The other option is distilled water online , which I think will be the best option

It's coming in at £15 for 5 litres which would last a couple of weeks

Not even considered heating the water but something I will look more into

If I'm installing fans for circulation then a grow room fan is much to powerful ,it would be like a constant hurricane

Pc fans are the way to go I think but would need to look more into them .

I’m not gifted in plumbing, but the RO system I had screws onto my kitchen faucet. I need attach it only when making a large batch of water and then detach when done.
