What else can I help you with?
How do you know whether a furnace damper is open or closed?
There should be a lever somewhere on the duct near the furnace. If it is open, the lever will be parallel to the duct. If the damper is closed, it will be perpendicular to the duct.
Should the return at the bottom of the wall be open or closed when the furnace is on?
Open, that`s where the cold air is.
Is an open fire or closed fire best for heating a house?
The answer is that a closed fire is best for heating a house.
Can you turn the main water off and leave your furnace on?
This depends on the type of furnace system you have. A forced-air furnace should be completely independent of the water system. An older, convection-based (no pump) hot water system will have an expansion tank, and will not need to have the main water on, except to replenish the system, which should happen infrequently. A closed-loop system could possibly over-pressurize as the water is heated, with the mains valve closed, and would trigger the pressure relief valve, dumping a few cups of water every time the furnace cycles until the system was dry; eventually, with the pipes in the furnace dry, the furnace heat would melt and destroy them.
Do the return vents attached to furnace need to be closed when air conditioning is running?
Not really, there's not much airflow when the furnace is not running.
Closed container where ore is heated to extract metal?
Depending on the scale, it could be a crucible, a furnace or (only in the case of iron) a blast furnace.
What is the difference between a closed combustion furnace and open combustion furnace?
A closed combustion furnace has a sealed combustion chamber, drawing outside air for combustion and expelling combustion gases outside through a dedicated vent, resulting in higher energy efficiency and indoor air quality. An open combustion furnace draws air from inside the home for combustion and expels gases through a chimney, potentially leading to energy loss and indoor air quality issues.
How does an expansion vessel work to maintain the pressure in a closed heating system?
An expansion vessel works by absorbing excess pressure in a closed heating system. When the water in the system heats up and expands, the expansion vessel allows the water to expand into a flexible membrane inside the vessel, preventing the pressure from getting too high. This helps to maintain a stable pressure level in the system, preventing damage and ensuring efficient operation.
Why is a Bunsen burner not used for heating when the air hole is closed?
When the air hole is closed, the flame is a luminous flame. This flame is not ideal for heating for the following reasons: it is not as hot as the non-luminous flame it is very unstable it produces a lot of soot thus, only non-luminous flames (the blue one) is ideal for heating. :)
Why reverse cycle airconditioning is not more effective in winter?
A Reverse cycle Air conditioner is MUCH more efficient than resistance heating. It is called a heat pump, and requires that the Evaporator and Condenser coils of a Closed Refrigerant System be reversed.
When the switch is closed how does the broken wire affect the heating element in circuit A?
If there's a broken wire then the circuit is no longer closed. It's open.
What are Examples of open and closed loop systems in the home?
Closed loop: 1. Thermostat --> furnace (constant temperature) 2. Toaster setting (light/dark) --> toast (IF the toaster has heat sensors) 3. Refrigerator cold/hot setting --> refrigerator inside temperature (constant) 4. Temperature setting for oven (not stovetop) --> oven temperature constant 5. Clothes dryer with moisture sensor 6. Washing machine water level Furnace. Temperature sensors control when furnace is turned on. Heating sensors in furnace control when air blower is turned on, and when flames must be turned off. Refrigerator. Temperature sensors control when refrigerant cycle turns on and off. Many TV functions, internal operation of disc playback and record, really ad infinitum.
