Came across a FB discussion talking about heating a greenhouse using Peltier units. I’ve no experience of using these so cant really say if thats feasible (does sound rather ambitious) but i did think maybe a seed propagator could work using them (much smaller area to heat).
An Arduino will be used to sense temperature and switch the units on or off - but not power I’m thinking.
The things can be purchased cheaply from ebay but I’ve on idea what to use to power them. could anyone advice what i should use to power ‘one’ or multiples - a link would be nice.
Any thoughts on using them appreciated
