Heating My Home
What home equipment and appliances use the most energy? View answer
About 60 percent of your home’s energy use comes from space and water heating. With new high-efficiency natural gas equipment – a 95%+ efficient gas furnace and either a .67 energy factor tanked or .82+ energy factor tankless water heater – you can significantly reduce your energy use. For more information see natural gas equipment.
How do natural gas furnaces compare to heat pumps? View answer
A natural gas furnace offers exceptionally comfortable, even heat – with 110 to 120 degrees at the register compared to 104 degrees from a typical heat pump. A gas furnace runs less often to maintain your home’s comfort. It’s more reliable with fewer repairs due to fewer moving parts. And it offers a 20-year-to-life warranty on the heat exchanger compared to a 5 to 10 year limited warranty on a heat pump compressor. To see how a new gas furnace would compare to a heat pump in your home, visit this page.
Are there any special deals on natural gas furnaces? View answer
What’s the best way to cool my house in the summer? View answer
We recommend an air conditioning system. A/C runs only when it’s hot outside (there are on average 13 days over 90 degrees in Portland annually). With proper maintenance, it should last 15 years or more. And if installed at the same time as a high-efficiency natural gas furnace, the combination system can be designed for optimal efficiency and can save you up to $600 in installation costs due to fewer permits, technician trips and other economies.
What should I know when considering a boiler and radiant floor heating? View answer
If you already have a boiler and hot water heating system and it’s time for a replacement, proper sizing and efficiency are the key considerations. Use a qualified contractor to do heating load calculations for your home so that the replacement boiler is properly and not over- or under-sized. Then consider the highest efficiency model you can afford, keeping in mind that the higher the efficiency, the lower your heating bills will be.
What is the environmental impact of the various home heating systems? View answer
Natural gas is the cleanest burning fuel. In fact, it is far less harmful to the environment than oil, wood, or electricity generated from fossil fuels. Natural gas produces about 30 percent less carbon dioxide than oil and about half that of coal or wood. When properly burned, natural gas produces heat, carbon dioxide, and water vapor. It produces almost no sulfur dioxide, carbon monoxide, dissolved solids, or particulate matter.
Selecting Water Heaters What type of service or maintenance is available on gas equipment? View answer

How do gas tanked water heaters compare to electric water heaters? View answer
A 40 gallon gas water heater produces 34 percent more hot water than comparable electric models and can recover heat about twice as fast. See a video on water heaters here
Are there high-efficiency tanked water heater options? View answer
Yes. The ENERGY STAR tanked water heater has an energy factor (EF) of .67. Based on current NW Natural rates, you can save about $176 per year with a high-efficiency natural gas tank water heater over a comparable electric model.
Unlike tank-style water heaters that heat water in a storage tank, tankless water heaters heat water only when you need it. When you turn on the hot water tap, a sensor tells the tankless water heater to fire up and start heating water as it flows through the unit. When you turn off the hot water tap, the tankless turns off as well.
Fireplaces Why would I choose a tankless water heater over a traditional tanked type? View answer
Since tankless water heaters only heat water when needed, they save energy and lower your operating costs. Plus, you never run out of hot water! While tankless units cost more than tank models to install, the energy saved typically results in paybacks of a few years or less for a family of four. Tankless water heaters also last twice as long (up to 20 years) and take up less space in your home.
Cooking with Gas Can I get a natural gas hearth without having an existing wood fireplace? View answer
Yes. A zero clearance gas fireplace is specifically designed for installation where there is no existing fireplace. Some are decorative in nature; others are better at producing heat efficiently. There are sizes and styles to suit about any project. You can build it into a wall and hang a mantel above it, put it flush to an exterior wall with a chase behind it or build/purchase a mantel cabinet for the fireplace. You may also choose a freestanding gas fireplace that resembles a woodstove, complete with logs but which operates on gas.
Once you have visited a retailer and selected the make and model of the gas range you wish to purchase, call our Service Solutions Coordinator at 877-243-5855 to obtain a contractor who can extend your gas line for your new range.
Converting to Gas What are the differences between a natural gas and propane grill? View answer
Propane grills differ from natural gas grills in a few ways. First, propane tanks must be refilled when they run out of propane. This requires going to a local propane distributor or a gas station to add more liquid propane to the tanks. A natural-gas grill takes advantage of your home’s existing natural gas supply used for other gas equipment so you don’t have to worry about running out. And grilling with natural gas costs about 1/3 the price of grilling with propane.
If you don’t have an exterior natural gas line available, you must have one installed. Call our Service Solutions Coordinator at 877-243-5855 to connect with a contractor who can install your natural gas grill service line.
