Which is better for indoor aquaculture boiler hot air heating?

First of all, what do you breed? My home in Nantong is almost as few as yours in Zhejiang. In our place, chickens, ducks, snails, etc. Generally, they are raised with self-built heating facilities, burning straws, sawdust branches and so on. It's both cheap and effective. If you want to realize automation or convenience, it is suggested that water heating and hot air are faster, but the duration is not as good as water heating and water heating, but the heating effect is good and energy saving. In addition, it is recommended not to use coal, but to use electricity, because coal has high energy consumption, that is, low utilization rate, and the price should be higher and higher, and electricity should be relatively cheaper and more convenient.
