Is Electric Heating Eco-friendly? Determining whether or not electricity is an efficient and ecologically responsible means to heat a home should include the initial electricity production as well. Burning fossil fuels to fire electric power generation is only around 30-60% efficient. There is also significant loss fro...

Which is the best home EV charger? That depends... Here's a suprising fact for many new EV owners - the charger for a shiny new Electric Vehicle is actually inside it! The charger is not the box on the wall, but is the equipment installed inside the car that takes the AC Alternating Courant electric sourced from your r...

Enter the Scrooser. The Scrooser is a German engineered electric scooter / e-bike with a top speed of 24 km (15 mph) and a range of 35.5 km (22 miles). It works with an Impulse Drive that is literally kickstarted by it's rider as the engine engages when the scooter reaches speeds over 3 km per hour.  The Scrooser no...

Buying an electric car (or EV) is on the increase For a lot of people though there's a nagging question in the back of everyone’s mind - When is the right time to make the switch to an Electric Vehicle - & which is the best EV? Over decades, and even more so over the last few years, the purchase prices of EV's cont...

Passive House design, how does it work? If you've ever sat in a car with black leather seats in the summer, particularly when wearing shorts, you already understand passive solar heat gain. It is a very simple concept that as a building technique dates back thousands of years. You simply need to find out where south is...

Why build a frost protected shallow foundation using prefabricated foam forms ? Building a frost protected shallow foundation (FPSF) is a well-proven alternative to building deeper, more-costly foundations in cold regions with seasonal ground freezing and the potential for frost heave. Traditional foundations for cold ...

Radiant heating systems are very common in concrete floors now because they provide a very balanced and comfortable distribution of heat. Those systems are most commonly hydronic, meaning heated liquid is pumped through tubing in the concrete which then radiates that heat into the house. View the slab on grade foam for...

Have you ever noticed that at times you can feel cold in your home even though the air temperature is exactly where you like to keep it? That's because, contrary to what most of us think, air temperature is not the main factor that determines human comfort in a building. To illustrate a point, let's start outdoors. I m...

There is some debate in performance building circles, particularly in the Passive House community as to whether or not you can add enough insulation below a concrete floor to eliminate the need for heating it. We have been on the fence about this and leaned to both sides at different times, but it seems we have now fa...

Here is our DIY video of  how to lay down tubing for our radiant floor in the Edelweiss House. We have a 10 zone system, allowing floor temperatures in each room to be controlled independently. HePex tubing was provided by Uponor, who also use building plans to give customers a zone plan to follow making the install q...

Similar to electric baseboards, hydronic heating systems facilitate zone heating as you can keep different rooms at different temperatures. Though different from electric resistance heating, hydronic systems are ultimately still using electricity to generate heat, so all the same environmental realities apply. Heating ...
