How big of a propane tank do I need?

Here are the steps we take before installing a propane tank at your home.

  • Step 1: Determine Tank Size

    Factors influencing tank size are the total square footage of the home, total BTU load of installed propane appliances and the climate zone. Typical horizontal propane tanks have a water capacity of 125 to 1,000 gallons and can be filled with propane to the 80 percent level.

  • Step 2: Determine Tank Placement

    We evaluate accessible, safety-approved sites when selecting a location for a propane tank. Considerations should include:

    • Building and safety codes, which vary from location to location.
    • Ease of access, to allow delivery trucks the ability to refill the tank in all seasons (tank must be located within 100 feet of the driveway).
    • Overall site design, aesthetics and landscaping.
  • Step 3: Tank Installation

    Basic tank installation can be completed in a few hours, either by our own service technicians or approved contractors who can complete the project in an efficient manner.

  • Step 4. Regulator Placement

    Regulators come with pipe size and distance requirements, just like tanks, and cannot be placed closer than 3 feet horizontally from any building opening, such as a window well, nor can they be placed closer than 5 feet from any source of ignition, such as an AC compressor. Our Carmichael Propane technicians will ensure that your tank is in compliance.

Our Automatic Delivery Program leaves the scheduling to us! We use a multi-variable mathematical equation that estimates the amount of propane in your tank based on your average use, daily weather and temperatures, size of your home, the number of people in your home, and other factors.

With Automatic Delivery, your delivery will be scheduled before your tank gauge reads below 20 percent full.
