Polysupers - Anypoint?

[user 6228]

Answers:

The answer to the first part W1 is 201.6 litres.
The energy E1 to evaporate 201.6 litres is 4.56E+08 joules
and therefore W2 the extra water generated in supplying that is 128 litres
thus W1+W2 is 329Litres.
EDIT:
correction W2 is 100 litres
so w1+w2 =302 litres

this is what OP is about ... what is the point of insulated supers... the point is honey involves a heat ... dont waste it.

Insulation is one thing but there are some wild claims which I don't think are substantiated, especially when some direct comparisons of harvests from mixed apiaries often show colonies in wood out performing those in poly.

I agree, maybe the bees have to work harder to remove moisture from the plastic or painted hives.

 

[Itchy]

Well, I'm open minded and will be listening to the talk on the 13th in Worthing.

I'm not clever enough to check calculations and all that stuff, I just want healthy productive bees

 

[Swarm]

That's the point though, Itchy. There are plenty of healthy, productive colonies kept in typical wooden hives.

 

[Itchy]

But could they be healthier, more productive etc etc?

You need a a statisitically significant sample of both types kept under a similar regime and climate to decide that. Murray MCGregor(ITLD) has 1000's of both types with definite procedures. His new investments are poly. According to him, better honey yield, better build up in spring.

And if you ask Hivemaker the same question?

I go with the published science...

and even then I look very closely...

Never mind published science, what about personal experience? Far too many successful wooden beeks IMO.

it would be unfair to ask someone who's livelyhood depends at least in part on the sale of the items in question.

To answer the original question, the most gain to be got from an insulated crownboard IMO, is when the first super goes on, to encourage the bees up to the warmest part of the hive, under this insulation, so along with an insulated crownboard, I believe there is a point in poly supers.
To add to the chorus of doubters on Derekm's figures, I have no doubt that insulation is way down the list of the things most important to the well being of honey bee colonies, and I'm not going to attend one of his 'shows', though if hes ever in the area hes welcome to pop in for a brew and try and convince me, there might even be some homemade biscuits on offer.

when we have that brew lets leave the kettle to boil away a litre of water and see how much gas or leccy its used...

Bees do seem to thrive when given plenty of work they have evolved perfectly to cope with though.

just as well as doing by leccy would cost over £300 to ripen 60Kg

Read a bit deeper and you will find that the nectar to honey process takes a little more than mere evaporation too.

That would be either myself or Murray then.

Bees choose to live in hollow trees....hole at the bottom, small walk upwards to the comb...says it all

chimneys (with top entrances) are quite common choices too.

Mere evaporation? its a prodigous feat! even with the little push of the invertase reaction.
Each time I look deeper into the physics, it just gets more amazing...
that why i want to give them a "following wind" rather than a "hard beat to windward".

That's a good point, although I suspect the tree scenario would be the first choice. Of all the chimney ones I've seen, most often the vent in the room has been closed or papered over so there is no up draught.
