A black bottom pool will be slightly easier to heat than a white bottom pool, but the difference will be very, very small.
Yes, some very small amount of extra energy will be absorbed by the black color and absorbed into the water that would otherwise be reflected by the white color pool, but this small amount of heat is dwarfed by the large amounts of heat that are lost or absorbed by the water due to air temperature, wind speed, evaporation, cover, heating method, etc.
Most people choose their pool color based on design and/or looks and then get a good pool solar cover to help keep it warm (regardless of the color).
A darker color will absorb and retain some of this heat/light, most will be absorbed or reflected by the water. Solar heating panels that circulate the water through the panels then back to the pool or alternatively a solar cover will do much more to heat the pool water.
From possibly to somewhat.
mainly because they are rated on BTU size...
This heat exchanger works wonders (with a sufficiently sized boiler). http://triangletube.com/HeatExchangers/MaxiFlo/HEMaxiFloOverview.htm
Besides the obvious answer of hot foods heating and cold foods cooling, hot peppers due to the capscacin in them will increase blood flow to the skin surface in the mouth which will noticeably heat up the oral cavity.
The service performed by central heating itself is heating a home or building. A central heating service or company can provide repairs or installation of central heating units.
Direct heating means heating an object directly by a heater but indirect heating means heating an object by another object which is being heated by a heater.
what is heating in chemistry
Yes Radiant heating is more environmentally friendly than central heating. You will find that out after you start saving money on radiant heating. Your Welcome.
how can the sun can produce heating directly in solar?
The answer is no. Radiant ceiling heating does not work as well as radiant floor heating in that heat rises so having heat in the ceiling will not be as efficient as heating in the floor.
what is public heating? what is public heating?
Radiant heating is a technology for heating indoor and outdoor areas. The sun is an obvious example of radiant heating. Radiant heating can be used anywhere. For example, a device used for radiant heating can be used wherever you feel the need to have some extra heat. However, the sun has radiant heating all the time regardless.
Oil heating is a form of fuel which is an alternative to electric powered heating. More information about oil heating can be found online on Wikipedia.
