Heater workbench
« on: March 05, 2019, 09:40:57 am »
showing off my workbench shortwave infrared heater
my own design , uses 350mm heat lamps
the lamp its running now is an osram 415v 3kw bulb , it consumes 1.3kw on 240v
the bulb has an white aluminium oxide  reflector on on the back half of the glass , it does well at keeping the aluminium housing i built cool
even though it consumes 1.3kw  it feels hotter than a 1.5kw 240v bulb i tested , i believe its due to the inbuilt reflector, plus it has about 2 to 3x larger amount of tungsten 
i constructed a full dimming controller box with 10ma rcd
it heats my midsection all the way up to my neck  , usually have to dim it down after a short while
also use it   to dry off metal parts after machining
makes it fun to work on stuff when its freezing cold

standing so close to this bulb makes this the most efficient heater there is lol
my chest is about 50cm away from the bulb , its the nicest type of heat

if anyone is going to do a build with heat lamps make sure you buy the ones with wire leads , the ones that uses electrical  contacts that also secure the bulb in place are prone to failure , at least in the larger wattage heat lamps

i tried out one of those bulbs that has a gold/ruby coating over 100% of the glass to reduce visible light but not infrared , it puts out a lot of red light and you can almost look directly at the lamp when on, i dont think ill buy this type again though

next i want to buy one that has a 50% gold reflector , i would have already bought one but the minimum order is 10 or something
seems a waste to throw out the gold at the end of its 5000 hour life though

it would be cool if you could cheaply get a 300x400mm  stainless sheet with  real gold coating on one side for a reflector insert , then i could just buy the standard lamps

how about gold plating one yourself?  ;) you can watch cody's lab video about electro plating metals with gold. It uses a small amount of gold so it won't cost that much either. you just need the right holder, sand off the paint, make sure the metal surface is clean (you can treat it with HCL as well) and then proceed to plating it.

That is a nicely build project :) I myself don't have a need for it (yet), since my overhead lamp I use for illumination of my desk provides so much heat that I mostly have six of the eight 80W T5 High Output tubes disabled. But soon I want to rebuild the lamp using LED strips, so maybe I will have a need for a heater like that ;)

Also try a heater under the bench, at your feet. Keeps your feet warm and the warm air then flows up your whole body. It's almost a religious experience!

yes i would like to do that , but then i got thinking maybe the lamps with the gold reflector built in , maybe the gold gets up to about  500C  and becomes an emitter itself ??

i probably cant  do a better job than the existing gold reflector bulbs

yes, we have a carbon fiber lamp with gold reflector in the works
carbon fiber is the same as graphene right ?
this one wont put out much visible light as it glows a dull red

here is the first heat lamp i bought ,  i have replaced the lamp itself, the lamp holder , reflector insert , connector box , and mounted it to a speaker stand
only the black cast aluminum housing remains , it was only 40$ delivered in Australia to buy it , it had a flat glass front panel that blocked 50% of the heat

the lamp i replaced it with has a secondary glass layer built in for safety, apparently falling glass fragments could start a house fire

This is one project I would go whole hog on. Namely buy one of these:https://www.aliexpress.com/item/pig-rotisserie-motor-Heavy-Duty-80kg-load-Stainless-Steel-pig-Spit-roast-rotisserie-motor/914780261.html

Attach the motor to a rotating barstool, for an all even bake. By synchronizing your thoughts and actions to the rotational frequency you can be afforded quiet periods of reflection interspersed with feverish bursts of competent action.
