Heat Resistant Material

Recommended Posts

What part of your solar water heater do you need this material for? Heat conductive material is best for housing the pipes - that way any heat absorbed by it from the sun can conduct through the pipes into the water easily. You can insulate the body of the the unit, but heat conductivity is what is needed between the pipes and the heat capture sheet/housing.

 

The use of 'squashed' copper piping painted black improves the absorption too iirc. Black for obvious reasons (it absorbs the heat), squashed slightly so that a larger surface area of pipe gets incident rays and thus more absorption of energy.

Was it cold when it was put in the steamer? Was it a thin glass mug? The glass here that John suggests would be much thicker and wouldn't be going through fast temperature changes.... extreme temperature changes throughout the year, yes, but slow changes that wouldn't cause it to shatter.

The mug probably wasn't borosilicate glass (aka pyrex), which is the kind of glass oven ware or lab equipement is made of.

"Regular" glass is definitely not heat resistent.

 

But even heat resistent glass isn't as heat resistent as metals.

That rather depends on the metal: ever seen a "mercury in glass" thermometer?

...

glassware is not heat-resistant, ...

A lot of laboratory work shows that you are wrong.
