I bought 3 of the 49.99 digital electronic thermostats today preset to 99.5 even if power goes out will reset itself to 99.5, should have them by Tuesday. I am really looking forward to them as in the evening my two incubators lose a degree and a half of heat.. in the day they could gain as much as 3 if I add water to the depleting water well it spikes humidity and temp rises, sometimes does not regulate back on its own. Was turning the eggs in one and electric turner in the hovabator. hovabator was much more stable after deciding not to add water anymore but rather just take a piece of a clean white tshirt and wet it.. so I could quickly slide it into the turners motor side where no eggs are. Loses no heat now from the lifting. Thinking about installing a drip line to the well... that I can just add water by unplugging and attaching a funnel to the input.
With all the thought going into it... make you wonder if you could not design a more efficient one for the price of the lil giant of hovabator..
