Best Answer

A two phase furnace includes 2 types of heat. Usually it is composed of an electric heat pump and also a nat. gas/ propane heat source when the temperature drops below a set range. The reason they use these is because heat pumps are very efficient when there's not a large temperature change required, but they're efficiency drops dramatically when the outside temperature (or ground temperature) drops below freezing.

The only other two-phase furnace would be a two-phase electric (as opposed to a three-phase electrical furnace.) But I don't think you're asking about 2 vs 3 phase electrical furnace systems... Those are quite rare.

Phase limit in induction furnace?

It means the Phase anlge is not matching with control board phase angle or more capacitor connected in the furnace line. we have to Remove some tank capacitor.


Is furnace a 1 or 2 syllable?

Furnace has two syllables. Furn-ace.


Two phase instruments?

There is no such thing as a two phase instrument. There is only single phase and three phase. You can only have: single phase/ one pole single phase/ two pole three phase/ three pole


Why Scott connection is used to convert three phase to two phase why cant you take two lines from three phase circuit?

In a two-phase connection, the phases are displaced by 90 degrees. Two lines (not 'phases') of a three-phase system will provide a single-phase supply, not a two-phase supply.


Is furnace a syllable word?

All words have at least one syllable. Furnace has two. Fur-nace.


What is the voltage level of two phase machine in three phase?

From one phase to the next you should see 208 Volts.From any phase to ground you should see 121 Volts.AnswerYou are very unlikely to come across a two-phase machine, as two-phase a.c. systems are archaic. A two-phase system has two phase voltages that are 90 degrees out of phase with each other, and was used many years' ago. These days, you have either single phase or three phase. So it's probably safe to say that there are no two-phase motors about, these days!


What raw materials are used in a Cupola furnace?

Two raw materials that are used in a Cupola furnace include rocks and briquettes. The cupola is a vertical furnace that is similar to blastfurnaces.


Does a two phase heater need a two phase thermostat?

Most electrical equipment are either designed to work on Single phase (two wires) or Three Phase (three or four wires). Two phase equipment are non existent today. A single phase heater will require a single phase thermostat while a three phase heater will require a three phase thermostat.


Why 2 phase induction motors are not used in industries?

A two-phase* system is archaic, and has been completely superceded by three-phase systems, so there is no demand for two-phase induction motors. (*A two-phase generator has two phase windings, displaced from each other by 90 degrees.)


What is two phase protocol in a dbms?

In two phase locking there are two phases. The first phase is known as Expanding Phase and locks are issued in this phase. No lock is released. Then after change all changes are committed and the second phase starts that is the Shrinking Phase in which all the changes are noted and the locks are released. No locks are issued in this phase


What is phase equilibria of two component system?

Lets call the two components Phase A and Phase B. Phase equilibria of a two component system occurs when the rate of change of Phase A to Phase B is equal to the rate of change of Phase B to Phase A - meaning that the total change is zero, hence equilibrium is achieved.
