if you put screens to keep birds out of the pipes the moisture from the exhaust will freeze, and the exhaust motor will not be able to vent there by tripping the furnace on a pressure switch fault. the pipes ie intake and exhaust should have a minimum distance of 15 inches apart, and the same above the ground to prevent snow drifts blocking them.
When thermal energy isreleased by the substance, it creates condensation and freezing process.
The best cost efficient furnace would be an Energy Star furnace. They are efficient in operation and provide an estimated 21% savings as opposed to other furnaces.
In the water cycle heat energy is released during the processes of condensation and freezing. 334 J/g is released during freezing and 2260 J/g is released during condensation.
When energy is removed from a gas, condensation occurs. When energy is removed from a liquid, freezing occurs.
For boiling energy is needed, so it's endothermic.
2 phase changes that are exothermic are condensing and freezing.
Particles absorb energy when boiling (vapourising), melting and subliming. Particles release energy when freezing and condensing.
Both condensation from gas to liquid, and freezing from liquid to solid, do.
There are two main processes where particles of matter release energy. These two processes are known as freezing and condensation.
A gas furnace is a furnace that operates to keep your house warm with the use of gas. Gas furnaces are very energy efficient furnaces, and are the most common furnaces used in North America.
Typically gas furnaces tend to be the most energy efficient. By purchasing a gas furnace when remodeling your home, not only are you being more environmentally friendly, you are going to save on your energy bills.
Gas furnace are more energy efficient in my opinion. Electric furnaces use forced air and when you blow air over an electric element, it takes more energy to keep it hot.
