See how much you could potentially save on your heating costs.

Tell us about your home and current heating equipment and we’ll provide operating cost estimates for your current setup, along with estimates for natural gas options.

Answer the questions below to the best of your knowledge, then click on “Get My Estimates” to see a comparison of estimated operating costs. You can adjust your inputs on the next page and see how it changes the resulting estimates.

Step 1 of 3: Your Current Energy Source

Outside of service area

The provided zip code is not eligible for NW Natural service. To find out if NW Natural serves your location, visit here.

Why do we need a ZIP code?

Your ZIP code helps determine which energy providers service your area. The costs of heating your home can then be estimated based on the publicly reported rate of the chosen provider.

x
Energy Type:
Gas
Electric
Oil

Why does the type of energy matter?

Energy sources are measured differently. Equipment and efficiency also differ between energy types. Knowing the type of energy being used is important to estimating the potential operating cost to heat your home.

x
Energy Provider:

Why does my energy provider matter?

Each provider charges unique rates for their service and product. We use the publicly reported rates of each energy provider to estimate potential operating cost to heat your home. Oil rates change frequently, so you can enter a known cost per gallon price.

Step 2 of 3: Your Home

Please enter the number of square feet!

x

Why does home size matter?

Simply put, the amount of space you need to heat affects the amount of energy required. For this step, please include an estimate of the finished living areas.

Please enter year when the home was built!

x

Why does the age of my home matter?

Because construction trends change over the years, we can tell more about how well your home absorbs or retains heat just by knowing when it was built.

x
Home Type:
Single Family
Townhome/Duplex
Manufactured
Mobile

Why does my type of home matter?

The type of home you have and its construction materials impact how much overall energy it will take to heat it.

x
Primary Foundation:
Finished Basement
Unfinished Basement
Crawlspace
Slab

Why does the type of foundation matter?

Your foundation can make a difference in your home’s energy consumption and this information helps us better estimate the amount heat that could be lost or retained.

Step 3 of 3: Your Equipment

x
Equipment Type:

Why does my equipment matter?

Each piece of equipment heats a home differently. This information helps us estimate how much energy is typically used to heat your home. Learn how we adjust the calculation if you don’t know your equipment type here.

x
Age of Equipment:
40 years
25 - 40 years
10 - 25 years
< 10 years

Why does the age of my equipment matter?

Newer equipment is more efficient, so we use this information to estimate how easily your current equipment can your heat home. Based on your input, we will use an estimate of your product's efficiency. If you know the exact efficiency of your equipment, you can adjust it on the next page.

AFUE

We will use default values of equipment age and efficiency. See the assumptions page for more details on how calculations are provided.
