Living 30 minutes outside of Yellowknife, NWT has its share of challenges. And these challenges start with living outside of the power grid coverage. And since we get so many questions about how we live off the grid and our off grid home systems, I thought I’d write a quick overview of some of the systems in place to keep our home going.

Our Off The Grid Water System
To begin with, we live on a beautiful lake that has pristine water. And that’s an obvious benefit when living off the grid. We pump water from the lake year-round with a well-insulated lake pump.
We use the water from the lake for everything from bathing, to washing dishes and even drinking. (We use a countertop water filter as well for drinking water.)
The heart of the internal water system is our SHURflo 2088-313-145BX which is a 12 volt DC diaphragm pump. It gives us plenty of pressure throughout the house whether operating a shower, tub, dishwasher, the toilets or our off grid washing machine. It pumps directly from our 1100 gallon holding tank and pressurizes the whole house.
Our Waste Water Removal System
From freshwater, we move to the discharge streams, those being both grey and black water.
The black water is anything that goes through the toilet. And by that, I mean the everyday human waste, more commonly known as poop.
Our black water goes directly to a 2000 gallon holding tank that is conveniently located below us. It’s approximately ¾ under the house and ¼ outside the house footprint yet still enclosed with an insulated structure.
The cover is easily accessible as we just added a ladder to it this past year. It also has a pump-out pipe that extends horizontally about 15 feet. This makes it pretty convenient when we have the local sewage company come to pump it out two or three times a year. That’s based on how many visitors we get and how many bran flakes we consume.
Our greywater system is somewhat different. It goes directly to the outside.
Our greywater gets distributed out the back of our property, or the lakeside. Sitting some 60 feet above the lake allows the water to be naturally filtered through the ground even though we sit on a lot of bedrock.
The showers and sinks all feed through one 2” PVC pipe and the washer through a separate 2” PVC pipe. In warmer months, this runs to a barrel and my wife uses it to water the garden in the very dry summers here.
We’re challenged in the six months of winter, ensuring that there are no low spots in the pipe. We need to keep a fair slope mixed with daily wood-stove heated water to prevent the line from freezing.
I failed this week. And it froze, resulting in 10 hours of heating the pipe with a hairdryer, complaining, a little cussing and a lot of begging to get it thawed out and running smoothly again.
I ended up running the generator and continuously running a hairdryer to finally get a particular section of pipe thawed.

Speaking of the generator, that leads us to the electrical part of our off grid system. Our off grid home is wired like any other house for the most part. And since we live off the grid, instead of receiving energy from the grid, we generate our own. We do have a few sources of power generation, that being two diesel generators, one regular gas-powered generator and also solar panels.
One of the biggest off grid living mistakes you can make is underestimating the costs of your alternative energy equipment. Some of the off grid expenses we didn’t expect were generator repairs and parts.
The two diesel generators we
have are 10kw Lombardinis that we have housed in a separate power shed located about 50 to 60 feet from the house. The shed is heavily insulated. That helps both winter temperatures as well as reducing noise. It is about 10’ x 10’ in size. Our generator shed also houses our extra 11kw Champion gas-powered generator. We keep that one as an additional backup to ensure we have power if there are any issues with the diesel.
UPDATE: We no longer have our generators or generator shed. Watch for an upcoming post on what happened plus what we are doing and planning now.
How We Live Off The Grid: We Depend on Solar Panels and Generators!
Learning how to troubleshoot generators is one of the most valuable things you can do if you’re preparing to live off the grid. Even if you’re just running a portable backup generator. This is especially true if you plan to move off the grid to a remote location.

Our Solar Panels Help Us Live Off The Grid
We get many questions about how we live off the grid through the winter months in Canada’s subarctic. We depend heavily on our solar panels for power year-round. However, we have limited daylight (about four hours per day) in winter. That’s why we recently invested in additional solar panels. We need to access all the daylight we can to power our off grid home.
eight Kyocera 80 (KC80) watt solar panels on our roof with an additional 10 recently purchased 250-watt panels purchased that will be installed this coming spring. If we get one this year. These are each critical pieces to our power system, more so while we live off the grid in the far north, where we need the power to ensure we don’t end up with frozen children statues.
Update July 2020: We installed 9 250 Watt panels last summer and it made a HUGE difference. We’ll be adding even more this summer.
Our Battery Bank System
Wondering how we capture, store, maintain, and distribute such self-generated power? We personally have a battery bank consisting of a dozen batteries that serve us well.
Our off grid battery bank system includes 12 Surrette 530 6 Volt Three (3) Cell deep cycle off grid batteries. These are specifically designed for solar panel photovoltaic, inverter, renewable energy, and alternative (alternate energy) applications.
We configured this battery bank for a power source set as a 24-volt system. The batteries themselves are easy to maintain. They do require occasional maintenance to ensure the water levels stay above the plates We also periodically conduct what’s known as battery equalization.
Our Schneider Inverter can be programmed to complete the equalization electronically. We originally had the Xantrex DR Series 2412 inverter giving us a 12-volt system. We decided to upgrade to a Schneider Conext SW4024 which gives us the advantage of operating at 24 volts. This helps especially when pumping water up from the lake without having to use our generator.
How We Live Off The Grid in Extreme Cold
Our two-story, chalet-style home is in Canada’s Northwest Territories, at about 62 degrees North. To the west of us is Yukon Territory, and beyond that is Alaska. It gets very cold up here in the winter. So we actually have multiple heat sources, yet the heart of our system is our new propane boiler.
Our Propane Boiler
Last summer, (2019), we had to install a wall-mounted combi boiler when our 250,000 BTU Weil McLain egp65 propane powered boiler finally died. The boiler itself heats our closed-loop glycol system that unfortunately requires electricity to operate the circulation pump.
After many years of faithful service, our old boiler finally stopped working in March, 2019. We managed with just our wood stove through a couple of -28 Celsius days in March and April while we saved money for a new boiler.
In June 2019, we finally had a brand new propane Vmax MTI combi boiler and on-demand water heater installed.
Our Off The Grid In Floor Heating System
n-floor heating systems are nothing new. But ours is a bit different because of the extreme cold temperatures we can experience in the winter. This past winter, for example, we had a couple of ten-day stretches where the temperature remained below -40 Celsius. So we need glycol in our lines.
The glycol (anti-freeze) gets heated and then flows through the manifold, a contraption that looks like an octopus. It directs the glycol through the in-floor PEX lines as well as the upper-level perimeter baseboard heaters.
This is a great heat source since it keeps the lower level floor warm in the kitchen, laundry room, bathroom, and living area. It also keeps the upper-level wall chill at bay.
Our Wood Stove
n addition to the boiler heat,
we have a wonderful Osburn 2400 woodstove. Our particular woodstove is rated at 100,000 BTUs with the capability of heating a home up to 2700 square feet. Update: New wood stove installed in November 2019!
Both our boiler and woodstove generally operate together throughout the colder winter months to keep our family comfortable.
The Firewood Situation
The availability and cost factor of a good clean wood source challenges those of us who heat with wood in the north. We have two different avenues when it comes to firewood. They are Home Grown or Purchase. And yes, there are pros and cons for each.
Home Grown Wood
In our region, we can find spruce and birch trees. Yet none grow very tall or large in diameter as would be preferred for firewood.
And to harvest any trees locally, we have to get a permit from the City of Yellowknife. The permit allows residents to cut trees for firewood in various “burn” sections scattered in the region. However, the closest burn sections are roughly a 2-hour drive from our house. And the fines for not getting a permit before cutting can be quite hefty. Note there is no charge for the permit.
Getting Firewood From Burn Sections
For those who don’t know, a burn section is an area where forest fires have gone through yet have not burned the forest completely down. Many trees, although charred, remain standing and available for harvest. The wood is not really bad, but it isn’t the cleanest.
When getting our own wood, we have to factor the cost of the trip required to get to the burn section. The road condition can have an extreme effect on both truck and trailer.
It is a *really* bumpy road. Our road is constantly being repaired and flexing due to the extreme climate that regularly impacts its operating condition. So the combination of the prices of gas, wear and tear on the vehicle and equipment, potential axle repair, or spring replacement makes a purchased delivered load a viable financial option.
When buying wood there are a couple of routes to follow. We generally have folks in the area that advertise wood for sale. The costs can be anywhere from $300 to $400 a cord. Many also have a delivery fee of $30 to $50 a cord tacked on top. When you burn 10 to 12 cords a year, like we do, you can see how the costs add up.
You also have to consider the cord size, whether it is chunked and split, and the delivery vehicle size. Then sometimes you’ll find that the “cord” is not a true cord and you’re shortchanged. These sellers to get a permit and will generally hit the same “burn” sections mentioned earlier.
The second option to purchase from a sawmill down in Hay River. It’s a community about five to six hours away on the south shore of Great Slave Lake.
The sawmill in Hay River has a huge 18 wheeler “push” trailer that carries from 20 to 24 cords of wood based on how well it is piled. The wood is much better quality, larger diameter, already split and not from a burn area.
As of 2019, the price for a delivered load is a flat $6,300 CAD or $275 to $310 a cord, based on how well it is packed. The order we received late fall was about 23 cords and we ended up splitting with a neighbor.
We Run Our Wood Stove 24/7
Although many will be shocked at the price (and we realize it’s costly) sometimes you have little choice. We enjoy burning wood and will run the stove pretty much 24/7 for 6 to 8 months straight. We let it go out about every 4 weeks to do a thorough cleaning but other than that, full flames ahead.
