I have a heater belt (as pictured below) for keeping homebrew warm during the cooler months, however it keeps things just a bit too warm.

It is just a simple resistive device that draws about 30W. Is there any reason why I couldn't simply use a half wave rectifier to simply halve the heat output, using say a 1N4007?

I once had a big soldering iron working the same way. Half wave in standby to keep it preheated, and full wave when operated. Maximum temperature was achieved pretty quick, maybe 10-20 seconds. It was very handy.

Your belt will heat just fine if you find a way to hide somewhere the diode. You need to do an experiment first before disassembling it to see if the half wave supply does make enough heat for your use.

Officially that is no longer allowed to avoid asymmetrical loading of the mains grid.

That is interesting. I have a commercially produced laminator here that has all sort of regulatory symbols on it that does exactly what I was asking about. Maybe the rules are different here?

We don't have the regulations like the EU have. A diode is a simple solution. A domestic light dimmer is another - just check the minimum load spec.

That's pretty much what I thought. I will try out just using a diode to see how it goes.
Eventually I will build a proper temperature controlled environment to house the fermenters.

You could use a regular light dimmer to regulate the power.
Alternatively, you use a simple on-off controlled by a thermostat.

If you lived in Kent, you would have no need for home-brew. ShepherdNeame is just a few miles away.

David,
Is it about now I call you an utter bastard :wink:

Although over here we like beer that can be cooler than lukewarm.

Maybe we should start an thread in the off-topic forum to discuss global beer prices/taxes. Making your own here is less than 1/4 the price of shop bought beer.

I will try the diode solution first since it will cost all of 25c. Later I plan to construct a temperature controlled bat cave.

I made one attempt at home-brewing beer. It tasted so bad that I ran down the road to wash my mouth out with real beer (Fremlins). The pub is next-door to my old house.

My attempts at home wine making were a litle more successful, but still not comparable to commercial product.

Real beer may be more expensive but it certainly tastes better! Of course this probably does not apply to Australian beer.

I now live almost 100 metres away from the pub, so the journey is more arduous than in my youth.

From personal experience, it is truly difficult to make bad beer. You really have to try.

I hate beer. I tried, but I just cannot learn to appreciate the awful bitterness of the stuff. Even sweet flavoured beer is awful.

In the rare case I want to drink any alcoholic beverage, I much prefer stuff like vodka, gin or whiskey.

The real sticker is how far you have to walk to get to the WC after drinking a few pints. :shock: Youth does have its advantages. :wink:

In my youth, Gents had to go outside. Ladies had to go to brick built toilets at the back of the pub garden.

Occasionally there would be a horrified lady return to the pub. My Sussex bull would stare through the Ladies' window. His head was so big, it blocked the daylight from the window.

The pub now has indoor WCs.
