What Is a Gas Furnace?

A fuel furnace is a furnace powered by pure fuel to supply warmth in low room temperatures. My fuel furnace has a variable pace fan motor to push heat air by means of the vent ducts in our residence.

A single energy wire connects the furnace fan motor and the thermostat to 120 VAC energy.

1. Gas Furnace with AC Power Connection



During a latest cleansing and upkeep examine, the service technician took quite a lot of measurements that I recorded for reference and future design planning. The furnace is kind of environment friendly.

It attracts 2.0 Amps underneath regular operation and three.9 Amps when the variable pace motor is working. The most draw is at 5.0 Amps utilizing a clamp-on multimeter.

This signifies that 10.0 Amps is probably going the very best surge present anticipated for this furnace’s variable pace motor.

As I discussed within the final article, my solar energy system makes use of a Sunny Boy 3800TL-US SMA inverter with a safe AC electrical backup socket. The precise socket connection is underneath the duvet.

3. Inverter with 120VAC, 12.5A Backup Power

This inverter can produce 1500 watts of 110 volts AC and might present 12.5 amps if grid energy goes out and the solar continues to be shining. I would like simply 5.Zero amps, so the safe energy from the inverter works simply fantastic throughout sunny days.

4. Configuration Providing 120VAC Backup from the Solar Array

Since a photo voltaic day right here is about 7 hours lengthy, I would like one other approach to produce electrical energy for the 17 hours my photo voltaic panels aren’t producing energy. I made a decision to make use of the Honda 2200i transportable generator.

5. Gasoline-Powered Electric Generator

The 2200i has a number of exterior energy sockets and might produce 2200 watts of 120VAC utilizing unleaded fuel. The 1-gallon fuel tank within the 2200i can hold the generator going for about 5 hours—9.6 hours if the economic system burn charge is about on the generator.

It’s been fairly reliable—and quiet.

Connecting a 6-gallon marine fuel tank to the 2200i gave me a 7-gallon energy system that may drive this generator for between 35 and over 67 steady hours—regular setting or “economy” setting.

By including a number of 6-gallon fuel tanks, you may run a generator repeatedly for days, however this single tank design is basically all I would like to supply 24/7 again up and hold my residence heat and comfy whereas electrical energy is out.

Multiple fuel tanks simply imply fewer refills. During operational checks, the inverter safe energy provide and the fuel generator labored simply fantastic and supplied energy to maintain the furnace working as desired.

Except for the time to disconnect from the SMA inverter and plug the furnace into an influence wire from the Honda 2200i generator, I skilled no downtime of significance.

I used the economic system setting for the generator, which gave me roughly 9.6 hours of run time for every gallon of gas.

During sunny circumstances, the generator can be used roughly 17 hours every day, so the 7-gallon gas provide may simply present over 5 days of furnace operation—or indefinitely by refilling the marine fuel tank periodically whereas the sun-driven SMA inverter was offering energy to the furnace.

Even on sunless days, the generator may drive the furnace for 67 hours repeatedly earlier than fuel refill can be required.

Home heating and air-con have been main considerations for me, and the SMA safe energy and fuel generator configuration met the problem.

My spouse is pleased as she now not worries about heating and cooling our home and holding meals chilly throughout emergency conditions, and I’m pleased as a result of the problem of discovering a supply for emergency energy backup for these main home equipment has now been resolved.
