Systems: Credit River’s Warmth and Fresh Air

  • Our HTP Boiler

  • The beginnings of our in-floor heating pipes

The elegant Credit River has been equipped with equally elegant, high quality systems!

The The home has the graceful design of a luxurious, mid-century Craftsman home, but the house’s bones and building systems are lightyears ahead.

The house’s warmth comes from a two key elements: a gas boiler and a wood-burning fireplace.

The gas boiler by HTP is fuelled by a large propane tank and powers the in-floor heating pipes, which are set into a 1.5 inch screed topping laid on top of our floor.

A screed topping is quite different than a concrete floor, though they’re made of very similar materials. Concrete is made up of cement, large and small aggregate, and water. The cement bonds together with the small and large aggregate – coarse particulate materials used in construction like sand, gravel, crushed stone, and slag – to create a very durable, strong, and heavy building material. Screed is similar to concrete in heft and composition, yet instead of cement and small and large aggregate, screed is only a mixture of cement and fine sand. The lack of large bonding aggregate makes screed relatively easy to crush, making it much more vulnerable to damage than concrete. Because of this vulnerability, it has to be covered by flooring — it can’t stand alone like a polished concrete floor can.

However just like concrete, a huge advantage to screed is that it acts as an effective thermal mass. It heats up slowly and consistently, and maintains its temperatures very well, making it the perfect material to surround in-floor heating pipes.

For additional ambience and warmth, the living room’s wood burning fireplace helps offset the in-floor heating system’s heating requirements. The wooden stove in the screened in porch/sun room provides some cozy added warmth as well.

As for cooling, the house has a forced-air system, powered by an energy efficient heat pump and equipped with its own ductwork, which disperses cool air uniformly throughout the house.

The HRV (Heat Recovery Ventilator) system, also with its own separate ductwork, is from Zehnder. We’ve always wanted to try out Zehnder’s wares, but previously our projects’ budgets haven’t allowed for their innovative yet costly products. We’re excited to finally be able to use one of their amazing and efficient ERV systems! We’ll be reporting back on our experiences with it once it’s up and fully running.

Finally, the house has been roughed in for solar panels, making for an easy adjustment and installation process when the time comes for a new building phase that includes solar panels. The entire roof has been made solar panel ready, specifically the south and east facing parts of the roof, which get ample amounts of sun.

This house has been a pleasure to design, and it’s so heartening to see it coming together so easily! Next time we talk about this project, we’ll be discussing the home’s beautiful and serene interiors.
