The internal test would be logical consistency. The external test would be observation of the real world.
I would suggest a histoy test considering you would have to remember all the people and what they did and also the years and dates some events occured in.
If you cannot test it, then hypothesis is probably the wrong word for it.
You would test your hypothesis by predicting what the results of your experiment will be so it's like a type of prediction. Another way is what do you think the outcome will be.
Only one at a time, since you would not know which variable(s) made the observed changes. You would need to measure each change separately. But if you want to test multiple variables, then you would need to test every possible permutation. If you want to test two chemicals, then you should test your control (a placebo using neither substance), substance A, substance B, and both substances.
That would depend on what type of boiler inspection INTERNAL or EXTERNAL or 5 year hydrostatic test
That would depend on the average ambient temperature of the area the boilers are servicing
There are many ideal boilers for critics. Some ideal boilers for critics include the Buderus boilers, the ORLAN boilers, and lastly the Crown Boiler company boilers.
The best brand for double boilers would be Cusinart. They offer a fantastic line of kitchen products and appliances.

All boilers are not coil type think of the pork chop steam boilers AKA cast iron sectional
Utility Boilers Industrial Boilers CFBC Boilers HRSG
Bacharach tests, (Depends on fuel) hydrostatic, O2, CO, combustion efficiency tests ,smoke test, POP Safety/ relief valve tests, stack temperature test
Since boilers are used in industries, they do not come under the purview of homeowners insurance and would rather come under Fire & Burglary insurance.
As I understood it, the problem was that the boilers needed replacement. In order to match the performance of the German boilers, we would have to install Cruiser boilers. This was considered to be too expensive and there were also questions about safety of the steam piping thruout the ship.
The three basic types of low pressure boilers are fire tube boilers, water tube boilers, and cast iron sectional boilers. Fire tube boilers heat water by circulating hot gases through tubes, water tube boilers circulate water through tubes that are heated externally, and cast iron sectional boilers have multiple sections that heat water as it flows through them.
boilers which are used in ships called as marine boliers.
