may stick with the dishwasher for now. I can easily get 30 jars in at a time and more if I slightly modified the bottom tray as it has a number of large gaps for jars to fall through.
It`s all a great idea, and If it works well for you, and a dishwasher is always available, I would not bother with buying or inventing of anything else for your target.
If I end up with solid buckets then I will have to dust off the warming cabinet plans and bribe my friend once more for the use of a three pin plug
For this case let me help you a bit with the information you could find interesting:
1) I`ve bought this Universal 220V LCD Temperature Controller ( Thermostat) on Ebay for less than 10 euro inc. delivery. (I`m not sure whether am I allowed to give the full links by the rules of the forum)
It has a Temperature Controlling Range from -50°C~ to +110°C
2) I`ve bought 28W 28X53CM Adjustable Temperature Reptile Heating Pet Mat for less than 8 euro inc. delivery (on ebay also)
All I gonna do is to place a foam rubber on a floor(it would solve wires problems/damages), put a Pet Mat on it connected with thermostat, set a stand holding a honey bucket (or buckets) over it and a thermo-sensor placed on a shelf, frame the whole construction with an empty polystyrene langstroth BB(BBs), and cover it up with a polystyrene roof.
It`s a simple, cheap, apiary-available and, hopefully, viable design
I did not tested it yet as I have not got the parts so far. But I`ll give it a go whenever it`s ready… and not just for a honey
Could it solve a heather/Ivy honey extraction problems If I preheat the whole frames, dear friends? What do you think?
Thanks in advance for your comments
