How To Install Natural Gas Line To A Generator?

One of the most notable advantages of a natural gas-fueled backup generator is that it is less expensive to operate than a gasoline or diesel unit. The expense of installing new gas lines, on the other hand, will be higher. The cost of the generator alone might range from $4,000 to $10,000, depending on the size required. A natural gas generator can cost anywhere from $5,000 to $10,000 to install, which includes pouring the concrete slab it needs to rest on, laying a gas line, and connecting it to your home’s electrical breaker box.

Is it possible to connect a generator to a natural gas line?

You’ll need to connect the natural gas line or propane tank to the generator if you’re using natural gas or LP gas to power it. You’ll also want to make sure you have the right valves for the gas type you’ll be using for your home generator installation.

How much does it cost to run a generator’s gas line?

When you run a gas line inside your home, you’re basically installing or extending it from the meter to the appliance. The cost of the project is usually determined by the type of appliance, the number of BTUs it requires, and the location of the appliance. Your plumber’s preferences for materials and access also play a part, but the appliance itself will have the most impact on your final price. As a result, most appliances have a wide price range. The pricing ranges of many appliances are very similar. For the reasons stated above, if you have two lines active, you may receive different pricing for each line.

Cost to Run a Gas Line to a Stove

You should anticipate to pay $10 to $15 per linear foot for a gas pipe to be run to your stove. This is one of the simplest lines to install in your home if you have a gas stove. It is also one of the most affordable because it is easily accessible, has a small diameter, and is simple to connect. Some homeowners may want to install a gas connection and switch to a gas stove because it is more efficient and evenly cooks meals.

Water Heater Gas Line Installation

You should anticipate to pay $10 to $18 per linear foot to install a gas pipe to your water heater. Water heaters consume a little amount of fuel on a regular basis. As a result, they may require a slightly larger line, but not as large as you would require for a fireplace. As a result, they are less expensive than lines for many other types of equipment. Despite the fact that your line will be inspected when it is installed, you will almost certainly need a comprehensive check of your water heater system after it is installed.

Cost to Run a Gas Line to a Dryer

Dryers are ubiquitous gas-powered equipment. You should anticipate to pay $10 to $20 per linear foot if you need a line installed for one. Your dryer consumes more gasoline all at once, but it does so less regularly than a water heater or an air conditioner. As a result of the thicker diameter pipe, it has slightly higher pricing. This type of dryer is frequently preferred by homeowners over electric dryers since it is regarded to be more energy-efficient, despite the fact that the initial cost of installation can be rather high.

Cost to Run a Gas Line to a Fireplace

The cost of installing a line to your fireplace varies between $10 and $20 per linear foot. Fireplaces require a more steady supply and have different BTU levels, necessitating a wide range of line supply size requirements. The type of fuel your fireplace utilizes, albeit natural gas is the most prevalent, can affect the price of your pipe. Homeowners may choose to add a gas fireplace to an existing home or build a new one, or they may want a line to convert a wood-burning fireplace to a gas fireplace.

Cost to Run a Gas Line to a Grill

A line to your barbecue can cost anything from $15 to $20 per linear foot. Installing a pipe rather than purchasing and storing small amounts of gasoline is safer and less expensive if you use your barbecue frequently. While the grill does not use much gas, the preparation for the project results in a greater expense. Only use a line to attach your outdoor barbecue if you intend to keep it immobile and in the same location at all times.

Cost to Run a Gas Line to a Fire Pit

If you have a gas line, fire pits are also more efficient and safer to use. You should anticipate to pay $15 to $25 per linear foot to have your pipe installed if you choose this option. Fire pits utilize different amounts of fuel depending on their size, which affects the cost of the project. They’re also installed below ground, which limits your options for pipe material prices and raises the entire cost due to the required preparation.

Cost to Run a Gas Line to a Pool Heater

While pool heaters are not widespread in some locations, they are commonly connected to a gas pipe when they are routinely used. Installing this will cost between $20 and $25 per linear foot. Connecting a line to a pool heater is a little more difficult. Despite the fact that the heater consumes less gasoline, your overall costs may be higher. This is primarily due to the proximity of the pool and the fact that you must go beneath the pool deck 4. Though they can be more expensive, they can be a terrific addition in locations with cooler conditions, allowing you to utilize your pool more throughout the year.

Generator Gas Line Installation

The cost of connecting a generator to a gas line runs from $20 to $25 per linear foot. If you have a generator, you will need to hire a plumber to run a line to the unit at the time of installation. This project does not usually take place underground; instead, it is dependent on the generator. Despite the smaller size of the required line, it necessitates specific materials and a little more skill, resulting in a greater price. A dedicated line to a generator eliminates the burden of keeping the fuel tank topped off and allows the generator to run for much longer.

For my generator, what size natural gas pipe do I need?

Though a generator may require 3/4 or larger tubing to connect to it, if kept short, a 1/2 hook-up hose is usually sufficient. We recommend that you contact your local gas provider or a certified plumber for assistance.

Question: how to solve fuel-starved electric generator: regulators “fighting” for fuel

A 500-gallon liquid propane tank powers a 25,000 Btu space heater and a 20 kVA standby generator.

A regulator exits the propane tank, and a regulator provides the stove and generator from the split.

When the generator is functioning in the event of a power loss, it frequently “surges,” causing the lights to flicker, which is bad for motors and electronics.

I’ve noticed the two regulators “fighting” on multiple times, and I learnt in school that you can’t install two pressure controllers next to each other and expect either to work.

Is there a way to manage the pressure between the tank and the second (home) regulator with orifice plates such that the required pressure is maintained at the upstream side of the house regulator with a “control action”?

GENERAC 8-22 kW AIR-COOLED GENERATORS INSTALLATION GUIDELINES(2014), which is mentioned in full below.

Reply: how to fix gas regulator surging / fighting for your 20kW backup electric generator

Your gas supplier should provide an authoritative response, as I’m not sure what the best solution is.

However, I believe the regulators are not properly installed, the pressures are incorrectly set, or the gas pipe is too small. An LPG tank that is too small is less common. (A common minimum size is 250 gallons.)

Check the gas regulator size, capacity, and location

Both primary and secondary regulators should be checked for location (and, of course, presence).

A first-stage gas pressure regulator is often put at the tank (or at the gas meter if using natural gas), and a second regulator is typically installed at or even inside each gas appliance.

In most cases, backup electrical generators necessitate the purchase and installation of a separate primary or first stage gas pressure regulator. The generator does not come with one.

The backup generator, on the other hand, will almost always come with its own second-stage gas regulator. You may need to set or change the regulator to the correct fuel type: NG (natural gas) or LPG (liquefied petroleum gas) (propane).

However, the position of that second-stage regulator should be found in your generator’s instructions.

Your plumber will need to compare the primary stage regulator’s delivery capability to the entire possible LPG demand.

A 20kW Generac electric generator will utilize 3.85 gallons of LPG or 14.57 liters of LPG per hour at a flow rate of

The location of the generator will also effect the needed pipe diameter, as shown in our gas piping distance figures below.

Check the gas piping diameter, length, elbows vs generator size & fuel type

It’s also possible that the gas piping’s diameter is too small for the desired flow rate or the distance the fuel must travel.

The gas supply and pipe must be sized at 100 percent load BTU / megajoule rating to avoid the problem you describe. According to what I’ve read, one of the most typical mistakes committed in LPG generator installation is using undersized gas supply piping.

  • The pipe for a 20kVA gas-fueled GeneracTM electric generator is normally 3/4″ ID (interior diameter).
  • In the 8-16kW range, GeneracTM generators commonly employ 1/2″ ID piping.

You’ll probably find a table in the installation manual for your generator that lists the maximum total distance of piping that can be used for various pipe diameters. You’d have to factor in the number of bends, elbows, and limits as well.

On natural gas, how long can a portable generator run?

To summarize, a portable gasoline generator can run constantly for a limited amount of time on a single tank of gas. Usually 12 to 18 hours.

When using a huge propane tank, you’ll discover that your limiting reason is most likely mechanical (typically engine oil). That means 5-8 days for most propane generators.

Natural gas or propane: which is less expensive?

Cost. If you pay $15.00 per 1,000 cubic feet for natural gas, you’ll get roughly one million BTUs, which is little more than 11.20 gallons of propane. Using this example, if propane costs $2.50 per gallon, natural gas is the less expensive option.

Is gas less expensive than electricity?

In general, gas is a less expensive energy source than electricity. Home appliances that run on gas are often less expensive to operate than those that run on electricity.

While the cost of purchasing and installing gas appliances may be more up front, homeowners who choose gas-powered appliances will save money on their utility bills in the long term.

How can I connect my house to the gas supply?

If you need to connect a property to a new gas supply or change the connection to the mains, you may need to:

You’ll need to contact your local distribution network operator to get your property linked to a gas supply (DNO). DNOs are the companies that own and operate the gas delivery infrastructure to your home. Enter your postcode into the Energy Networks Association’s postcode search tool to find out who your DNO is and how to contact them.

What is the fuel consumption of a natural gas generator?

It’s vital to keep in mind that the cost of running a generator varies depending on the power demand, and many modern generators have low-fuel or half-load modes. The estimated expenses of running your generator could be reduced or increased depending on these variables.

Gasoline Generator

Portable generators are most commonly powered by gasoline. A typical 5-kilowatt generator uses roughly 0.75 gallon of gasoline every hour. In July 2018, the average price of gasoline in the United States was $2.89 a gallon. If you used the portable generator for a day, it would use roughly 18 gallons of gas, which would cost around $52 per day to run. Because gas prices change, running these types of portable generators for an extended period of time can be costly.


Portable diesel generators are less prevalent, although their fuel costs fluctuate like gasoline’s. Diesel costs roughly $3.17 per gallon on average. When running at full capacity, a 20-kilowatt generator will consume around 1.6 gallons of gasoline every hour. As a rough estimate, the cost of running the generator for a day would be $122.

Propane Generator

In the portable generator market, propane generators are frequently the cleaner energy alternative. Propane, on the other hand, burns more fast in a generator. A 20-kilowatt generator would consume around 3.45 gallons of gasoline each hour. As of March 2018, the average price per gallon for propane in the United States was roughly $2.50. A portable generator would use roughly 83 gallons of gas and cost over $200 to run for 24 hours.

Some standby home generators use propane, which is stored in big tanks on-site, which helps to reduce expenses by requiring fuel to be purchased in bulk less frequently. Under full load, a 22-kilowatt generator for the residence will burn around 3.6 gallons per hour. The standby generator costs the same as the portable version to run, a little more than $200 each day.

Natural Gas Generator

Because many homes are already supplied with natural gas, natural gas is quickly becoming the preferred fuel for residential standby generators. Natural gas costs $3.25 per thousand cubic feet in the United States right now. Because a 7-kilowatt generator uses around 118 cubic feet per hour, the cost of operation is only $0.82. Operating costs for a larger 15-kilowatt unit rise to $1.71 per hour, utilizing 245 cubic feet of natural gas.

This indicates that running a generator for the 10-minute “workout period” once a week would cost roughly $4 to $5 each month. And, depending on the energy load, the generator will spend roughly $20 to $40 every day during a power outage.
