How do you propose to use that stove? Put the block in the oven, or sit it on top of an element?

im pretty sure there was a hint of sarcasm in that post, coz putting the block in the oven would be funny.
I havnt thought too much about the teting, but now wrapping my mind around the problem id say.. hm..
connect tube to block and to tap, place dads digital thermometer(range -50 °C to +70°C accurate to 1/10th a degree.)somewhere before the block.
add thermal grease to block, place block on stove, weight down.
turn on water note temperature and time taken to fill jug in sink.
turn on stove , wait 5 min, note input water temp, out put water temp and time taken to fill jug.
vary input water volume, noting temp and time taken to fill jug.
asumptions: that stove heat production remains conctant, hence any difference in output temp can be attributed to the blocka ability to absorb heat from the stove.
I ordered a slab of Aluminium today.

Length: 217 mm
Width: 58 mm
Height: 20 mm
Material: AlMg 4.5 Mn
Weight: approx. 0,75 kg
When i asked the seller about the hardness of the material he responded that it was medium hardness and was workable with a hand held dremel and files and such. but not so soft that it would smear.
As for the dremel, i guess the tool im missing is an end mill, they included a toothed mill. i saw end mills for approx 2 euro a pop. dont know how high or low grade it is. For 2 euro its worth a test, so ill be pickup that endmill soon and look which files they have. will update this post.
