So currently I'm in the process of organising my collection all into the one room with the intention of having this room's ambient temperature regulated to the correct heat with a couple fans to circulate the air over these heat sources.

I am just wondering what a "cost-effective" efficient solution to thermostat stacks of 4 vivariums would be? Currently I'm running this type on each enclosure individually. They are all going to be 3-4ft vivariums.

The other problem I have is that I'm UK based, so I believe US products won't work, even if adapted, because of the different standards in what we get out of the wall over here. Naturally to save any Americans Googling and ending up in here, I'm not fussed if people recommend US options. Might give me names to search and find the UK equivalents potentially.

Cheers,
