Heaters and Coolers

[BcBlizzard]

I was wondering...
1. Are there research upgrades for the habitat heaters/coolers? A lot of them are needed to keep a large habitat warm in a colder zoo climate
2. What ways do you use to hide your heaters in habitats or don't you bother?
3. Do you use heaters/coolers on guest paths? I sometimes see guests complain about the heat and wonder if they would benefit from a cooler unit but it would take so many to cover all the paths.

Just curious :)

you can click on them and increase the radius

But a radius of 20 costs more then 2 heaters with radius of 14.

You can use shift and sink them a little underground, they'll work and be out of sight. Or you can place some scenery round them.

- No research upgrades I'm afraid

- I don't bother hiding them, they are small and the animals aren't bothered

- Yes, the guests are often complaining it’s too hot/cold so I place them around the paths at a comfortable 24-25 degrees Celsius
