Why Do We Keep Our Windows Open Year Round?

Sounds ridiculous, right? Not so fast. Many of us are effectively doing just that.

The U.S Environmental Protection Agency estimates that home owners can typically save 10-20% of heating and cooling costs – just by sealing their homes properly. Let’s talk about that number for a second. I spend roughly $300.00 on heating every month. That is $1,500.00 per season. 20% of that would be $300.00.


There are the more obvious areas we worry about; like the cracks around our windows or drafty doors. But there are a few other culprits that most people forget about. Recessed lighting, furnace flues, dryer venting and wiring holes can have a massive impact on indoor/outdoor air exchange. Even filling gaps in your existing insulation can make a sizable difference.

Besides the economic benefit to sealing and insulating appropriately there is also a benefit for allergy sufferers.

Better insulation and sealing = less exposure to allergens.

So how can you tell if your house is leaky? There are companies that specialize in detecting leaks with blower door tests. Or you could be thrifty! Light a candle; hold it by your door or window and see if there is a flicker. If the flame is flickering, you had better seal that window!

Carbon Monoxide: The Invisible Killer

As we close our doors and windows for the winter, Greenwood Clean Energy would like to remind you to remember to change your carbon monoxide (CO) alarm’s batteries. If you do not own one –  now is the time.

Carbon monoxide is an invisible killer. It is an odorless, poisonous gas and you can’t see it; further adding to the importance of a CO alarm.

Carbon monoxide warning. Cant bee seen, heard or smelled.

There are lots of safety tips including great mini-lessons for the kids on the NFPA’s website.

Be safe this holiday season.

Top Perks of our Wood Boilers

People praise our wood boilers for their efficiency and high-tech approach to a tried and true methodology, but lost in a lot of the science are some of the less publicized benefits of our boilers.


Though it’s an impressive, cutting-edge piece of technology, our furnaces work with your existing heating ducts and thermostat, so really the only difference you should notice is the dip in your energy bill. A quick trip to the furnace itself about twice per day will leave your home (and hot water) toasty around the clock.


Our The Greenwood Frontier Series isn’t in the same class as your typical wood furnace. Each boiler is equipped with an on-board computer that continually monitors performance and uses predictive control to ensure peak boiler operation. The temperature fluctuations you normally get with an old wood boiler aren’t a problem.


Each Greenwood boiler approaches 85% burn efficiency, meaning the vast majority of heated burned is recaptured and used to heat your home. Even the smoke and gases from the burning logs are burned and turned into usable energy, leaving almost zero particles. They meet the same safety standards as your indoor water heater would, so Greenwood boilers are safe to use indoors.

Guilt-Free Energy

While we hear a lot about the revolutionary way we burn traditional biomass fuels, our customers have been telling us about a less tangible, but equally important benefit to their Greenwood – the increased comfort and their guilt-free energy use. There’s no real way to quantify it, but imagine being able to crank up the thermostat in cold months and not automatically think about your increased use of fossil fuels. With a truly renewable source of energy and nearly zero emissions, the Greenwood is the perfect companion to an already eco-friendly home or the foundation on which you start one.

Renewable Energy Takes the Lead in Europe

This week our attention is drawn to a remarkable increase in the use of renewable energy in Europe.

Recent reports indicate that Germany,  had impressive growth in renewables through the first half of 2014. Germany is relying more on renewables – wind, solar, hydro and biomass – with an extraordinary 28.5% of its energy coming entirely from renewable sources! Time magazine wrote an interesting blurb on Germany and its state-subsidized program: Energiewende.

So far, leaders from 28 European nations agreed, that by the year 2030 they will have slashed greenhouse gas emissions by 40% of the levels from 1990.  That is a remarkable feat as well as a solid stance: that climate change is a real and formidable opponent.  The U.N’s latest climate assessment indicates that we are headed toward irreversible impacts such as rising sea levels to even throwing off the male:female ratio.

Rajendra Pachauri, the chairman of the Intergovernmental Panel on Climate Change (IPCC) states that  “The IPCC assessment, which incorporated the findings of three other reports over the past 13 months, reaffirms with 95% certainty that global climate change is both real and a mostly man-made problem.”

He went on to say, “All we need is the will to change, which we trust will be motivated by knowledge and an understanding of the science of climate change.” Read the article here.

The Cost of Wood Pellets Is On The Rise

If you are worried about heating costs this winter, you are not alone.

Everywhere you look there are forecasts about how cold and snowy it is going to be. What makes this worse are the reports that heating costs are also on the rise as well.

If you’re using propane – you’ve likely already felt the pain of handing over that monstrous check. Propane prices have been on the rise for several years now and people are desperate to find some relief.

That relief has come to some, in the way of wood pellets. But new reports indicate that wood pellet prices are on the rise. Due to an abnormally cold winter last year, they were not able to harvest trees as they normally have in years past. In addition, the demand from overseas has also been rising.

Wood pellets ignited in flame

But I am not here for doom and gloom. There is some good news. Some folks in the business of selling pellets have come up with some ideas to help out:

  • Make sure you plan ahead (like NOW). Start to pre-order your wood pellets where it’s available.
  • DON’T HOARD! It makes it difficult for everyone to obtain a fair share of pellets.
  • Consider your options. Wood pellets are processed wood, hence the cost. If you are in an area that has plentiful wood, you may want to consider today’s log-wood fueled appliances like the Greenwood Frontier CX.

Getting the Most Out of Firewood

So, you are heating with wood. So how can you tell if you are getting an efficient, green, clean burn out of your wood supply — much less all the energy you put into preparing it? Are you aware of the tons of outside variables that affect how much heat you actually GET out of that batch of firewood?

Our friends over at Mother Earth News recently published a nice article on the topic. Some highlights:

  1. Dry wood gives you more bang for your buck. What I mean by this is: if you have DRY wood it means you’re not wasting energy. Let me explain further. When green (wet) wood  is burned,  about 15% of the energy from that log is used to turn the water inside of it,  into steam. After that it can finally get to combustion temperature. The end result is essentially throwing away 15% of that log. If you pay for your wood you may as well take a handful of change. Get in your car. Get on the freeway. Open your window. Stick your hand out and let all of that money fly right out of your hand. (Not recommended or endorsed by Greenwood, by the way).
  2. Wet wood causes smoke which in turn creates creosote. Creosote builds up in the chimney and can cause fires, if not properly cleaned and cleaned often.
  3. Smoke = Waste. The EPA is setting very strict regulations around the amount of pollution that consumers are allowed to produce.

5 Reasons to Buy a Greenwood Boiler

Thinking of switching your heating system to a different, more eco-friendly solution? We’re recognized as the leader in renewable heating appliances, and here are five reasons why a Greenwood boiler might be right for you and your home:

Save Money

If we said you could save 70% on your heating bills, would that be enough to get your attention? With just a few logs, you can heat your entire home for a whole day. Oh, did we mention it also heats your hot water?


Our wood burning technology burns not only the wood, but the smoke and the gases, creating a virtually smoke-free result. For areas plagued by excessive wood smoke, this solution can dramatically reduce air pollution from wood smoke. The Greenwood Frontier Series meets EPA Phase 2 emission standards and is the only wood burning boiler that is allowed for sale by the Washington State Department of Ecology.


The Greenwood Frontier Series is clean burning, low maintenance heating appliance that uses your existing thermostat. When installed in a forced air, hydronic, or an in-floor radiant heating system, the only difference you may notice is the dramatic drop in your heating bill. Controlled by an on-board computer, your Greenwood boiler will keep your home warm and even during the low-demand spring and fall seasons.

Energy Independence

If you have access to firewood, you’re set! You don’t even have to split wood – high temperature in the firebox eliminates build up and reduces ash. Greenwood furnaces release no incremental emissions into the environment and use biomass fuels, which are a fully renewable source of energy.

Product Performance

Our boilers approach 85% efficiency, which means the vast majority of the heat released by the burning wood is captured to heat your home. They burn their fuel completely, leaving a minimal amount of particles to create smoke, creosote, or ash. Greenwood boilers are easy to maintain, too, requiring significantly less maintenance than wood stoves or outdoor wood boilers.

It’s THAT time. AGAIN.

You hear that? ‘Tis the sound of my heart shattering into a million pieces at the thought of the summer of 2014 drawing to a close. The warm embrace of the summer wind that would wrap itself around me when I stepped outside, will soon be replaced by the icy winds of Jack Frost. I shudder at the thought of his long, sharp, icicle-like fingers raking across my back.

Ok. Ok. It might be that I am a little over-dramatic about winter coming. But in all seriousness I not only dread the cold –  I also dread paying bundles of money to heat my house.

Before Sir Frost shows his hideous face let’s take a look at this video clip here on Home Energy Savings from our friends at This Old House.


Why Purchase a Wood Furnace

Heat is a basic and often overlooked or expected part of your daily life. You need to heat water for cooking or cleaning; you must keep yourself warm and during the dead of winter, you need to heat your house. For all these activities, you have several products including gas or oil furnace or wood stove, electric heater and certainly a water heater. Most of them cost quite a bit money to purchase and operate. If you are like a lot of people, you keep your eyes open to better options.

Greenwood Frontier CX Wood Furnace

A wood furnace or a wood boiler is among the appliances used for generating heat, boiling water and other purposes. A furnace of higher quality provides more energy for less fuel and keeps your house free from smoke. When used properly, it ensures that use less wood and have a warmer home. You can understand why it is essential to understand its benefits. Here are some of the benefits or criteria to use in evaluating a wood stove.

Clean burning – Indoor wood boiler leaves very few particles that cause smoke, ash and creosote. It is as the boiler burns the wood completely.

Energy efficient – It is energy efficient as it achieves over 80% thermal efficiency. It means the most of heat released by burning wood is captured and heats your home efficiently. Note: European and US wood furnaces are rated using different scales for efficiency.

Cost effective – Installing a wood furnace is economical for you as it reduces your overall energy cost. According to a study sponsored by the Canadian government, you can reduce your energy cost up to 70% by the installation of indoor wood stove.

Eco-friendly – Using a wood furnace, like a Greenwood Frontier CX, is an environmentally friendly choice since it releases very little smoke from the burning wood. Reusing the energy from the biomass in the active regeneration cycle is a renewable source of energy.

Low maintenance – It is easy to keep the furnace maintained. It doesn’t need to invest money in its maintenance. Further, you needn’t to clean it often in comparison with wood stove or outdoor boiler.

Long lasting – Yes, a wood stove of good quality lasts for a longer period of time if it is purchased from a reputed manufacturer such as Greenwood. A trusted manufacturer gives solid warranty for its entire appliance, not just a portion of it.

Reliable designs – Wood furnaces are available in two basic designs – downdraft or updraft (like a Greenwood). Identify your taste and purchase the boiler of your choice.
