Is it OK to convert your high efficiency furnace from its now inside air intake to start getting the intake air from the outside?

Yes, most if not all 90+ efficient furnaces are designed to take primary or combustion air from outdoors. That is partly where they get their high efficiency rating from. They are not using air that has already been heated for combustion.


Does transformer has high or low efficiency?

Since, transfformer is a Static device (ie. no moving parts in it) hence it is the most efficient machines ever made by man. However, in rotating machines there are various losses like friction and windage, losses in commutator etc. So, yes, Transformers are highly efficient devices.


Vent high effeciency furnace into chimney?

No, check local codes and installation instructions for the furnace.


What is the Cost of a 16 seer 4 ton trane ac and furnace?

We just had the whole trane system installed. It is the same specs you are asking about. It also has a new furnace that is high efficiency as well as new thermostat that is digital. We paid $7,800 without the $1500 tax credit. $6,300 total.


What are the most efficient engines?

The most efficient engines are typically those that maximize energy conversion and minimize waste. Diesel engines, especially turbocharged and direct-injection variants, often exhibit high thermal efficiency due to their higher compression ratios. Additionally, gas turbine engines, used in jet propulsion, are designed for high efficiency at specific operating conditions. Electric motors are also highly efficient, converting over 90% of electrical energy into mechanical energy with minimal losses.

How does the presence of water in a furnace affect its performance and efficiency?

The presence of water in a furnace can affect its performance and efficiency by absorbing heat energy, which can reduce the overall temperature inside the furnace. This can lead to a decrease in the furnace's ability to reach and maintain high temperatures, impacting its efficiency in heating materials or spaces.


How can I properly vent a high efficiency furnace through a wall?

To properly vent a high efficiency furnace through a wall, you should consult the manufacturer's guidelines for specific instructions. Typically, this involves installing a vent pipe that extends through the wall to the outside, ensuring proper clearance and sealing any gaps to prevent leaks. It is important to follow local building codes and regulations to ensure safe and efficient venting of the furnace.

What is a high efficiency furnace I should look into buying in order to keep my 5000 square foot home warm?

a high efficiency furnace is a furnace that uses less electicity and saves on heating expences. they are very useful in the winter and great to lower your central heating bills.


Why does a high efficiency furnace main burner shut off after initial ignition?

A high efficiency furnace main burner shuts off after initial ignition to maintain the desired temperature in the home and prevent overheating. This cycling on and off helps the furnace operate efficiently and safely.


What are some ways to improve oil furnace efficiency in a home heating system?

Some ways to improve oil furnace efficiency in a home heating system include regular maintenance, proper insulation, sealing air leaks, upgrading to a high-efficiency furnace, and using a programmable thermostat.


Why does my high efficiency furnace shut off after the initial ignition?

Your high efficiency furnace may shut off after the initial ignition due to issues such as a clogged air filter, a malfunctioning thermostat, or a problem with the flame sensor. It is important to have a professional technician inspect and repair the furnace to ensure it operates efficiently.


When operating a high efficiency nat gas forced air furnace and heat pump at what cost ratio or percent of gas therms to kilowatt hours does it make more sense to use the high efficiency furnace only?

There are 3413 btu per kWh and 100,000 btu per therm of natural gas, these are constants. In order to give a correct answer the exact efficiency rating of the high efficiency furnace and the energy costs per kWh and therms would need to be known.
