Convert tons to amps you must first convert tons to BTUs per hour after which you can convert this value to watts then use the formula amps watts volts to solve for amps. But a large commercial unit or one with features like a convection oven or quick-heat burners draw 50 to 60 amps.

1364 Amps if you use 220 V.
How many amps does a gas furnace use. But if you plug such a device into 220 V the current generated is only 1364 Amps there is no need for amp breakers. The Taco 570 valves I replaced used 216 watts to keep themselves open. Most furnaces list a 15 amp.
For 25 Amps for example you would already need an amp breaker. The typical RV is usually designed with either a 30-Amp or a 50-Amp 220-VAC Service that powers all of the electrical equipment and appliances the owner may want to use while camping. For example the AF AFG AFII and NX burners have a UL label maximum rating of 58 amps.
At 120 volts that is a minimum draw of between 1080 and 1440 watts if the furnace isnt brand spanking new and in. However the RV typical AC amp pull is 12-15 amps at the start then 3-6 amps while running. Technically 13 horsepower is equal to 248 watts but given inefficiencies and the way motors are rated the actual power consumption may be 600 or 700 watts.
These numbers alone dont pose any problem The typical RV is usually designed with a 30 amp or 50 amp 220 VAC service. This chart approximates the fuel consumption of a natural gas generator based on the size of the generator and the load at which the generator is operating at. Most gas heat furnaces use less than 600 watts of electricity or less than half of a typical 15 amp electric circuit.
You can run these 247 and it will still use less than an old 1 stage blower uses in its normal furnace onoff cycle when heating a house. If there is a rating available in watts or amps you could get a more accurate answer. To add to Christy Hicks answer the electric loads in a furnace are electronics amp the gas valve solenoid 1 amp the circulation blower.
A standard kitchen range with four burners and an oven could draw 30 40 or 50 amps. Subsequently one may also ask do gas boilers use a lot of electricity. The newer zone valves are fantastic as well.
The main features of a gas boiler that use the most electricity are the central heating pump and the boiler fan. Click to see full answer. Horsepower ratings of furnaces dont directly translate into power consumption.
This value enables flexibility so the burner can be built with various components including. Given an air conditioner with 2 tons of. Only a few furnaces that have 5 ton drives in them need a 20 amp circuit.
Watts consumption and Amps drawn by RV Furnace The typical amp pull by an RV furnace is 65 amps. The major amount of electricity used with gas heating is in connection with the blower and the watts required depends on the type of blower. Im going to assume you are asking about electricity use instead of a scientific definition of power.
Please note that this table is intended to be used as an estimate of how much fuel a generator uses during operation and is not an exact representation due to various factors that can increase or decrease the amount of fuel consumed. So much that its not worth worrying about at all. Even though the electrical power supplied to these RVs is designed to be adequate for the average family while they camp far too often the added equipment that may be used will overload the circuit breaker.
The new DC high efficency blower ECM variable speed use very little electricity. A gas furnace uses a negligible amount of electricity for lighting the flame. Same as AC in cooling mode Electric resistance heating varies by size eg 42 amps for 10 kW heater at 240v 1800 kWhmonth 6 hrday Furnace Blower 12 hp motor - 440w 4 amps 105 kWhmonth 8 hrday Heater portable - 1500w 125 amps 15 kWh per hr of use Whole House Attic Fan 30 - 1000w 85 amps 96 kWhmonth 8 hrday Ceiling.
Furnaces are measured in how many BTUs they use per hour to achieve this temperature increase. Older gas furnaces may use one-speed fan motors and they use approximately 400 watts per hour of activity. The Taco Sentry ball valves use 144 watts while open Im guessing to run the LED and keep the capacitor topped off and only 1284 watts when charging the unit to open it after its been off.
How many amps does a stove. To compare various efficiency levels multiply the price of gas per therm by 1 million then divide by 100000 Btu per therm then divide by the efficiency of the furnace. Iron core ignition transformers split-phase motors higher horsepower motors and other accessories that are outlined in our UL Construction Files.
Convert tons to BTUs per hour by multiplying it by 12000. For example a furnace rated as 100000 BTU input uses 100000 BTU per hour. Bigger multi-zone mini-split units usually need amp breakers.
The blowers usually draw 7 to 10 amps and the burner assembly usually around 2 amps so together you are looking at a low of 9 amps and a high of 12 amps.
