Solar thermal collectors

All about solar thermal collectors

...thermal solar is useful, so we will outline the options. Evacuated tube solar thermal collectors: Solar thermal collector © Viessmann This is the most common type of solar thermal collector you will likely see on the roof of a home. The collector panel itself is most commonly made up of glass tubes that conta...

Thermal batteries: how to passively store heat

...thermal battery? Thermal mass of any kind can by definition be called a thermal battery, as it has the ability to store heat. In the context of a house, that means dense materials like bricks, masonry and concrete. Even a jug of water sitting in a sunny window is a thermal battery of sorts as it captures and later re...

Energy modeling simulation of heat loss through thermal bridging
Efficient home design

What is a thermal bridge and why is it so important to break it?

...thermal bridges: It is not only sensible to address thermal bridging in construction, it is becoming law. Recent revisions to building codes have increased the thermal requirements of building enclosures in many regions, including requiring a thermal break. Contrary to common assumptions, the insulation value...

R values and insulation performance
Efficient home design

Understanding thermal performance

...thermal resistance. While R-value is useful, it doesn’t tell the whole story about heat flow through building enclosures such as walls and roofs. Recently, a study by RDH Building Engineering Ltd . h as shown that real world thermal performance depends on a large range of factors including temperature, age, thermal m...

Concrete floors and timber frame as thermal mass

The pros and cons of thermal mass in buildings

...thermal mass in it, any such savings pretty much cease to exist because it might take the entire day to drop even a full degree. The disadvantages of thermal mass in homes: Let's speak to the potential downsides of thermal mass first - if a home is regularly left empty for several days at a time or if you keep a co...

Solar thermal collectors

Product of the month: Solar water heater with overheating protection

...thermal heat collection . Purchase: You can purchase individual solar components separately, but buying a pre-engineered solar thermal package can make more sense than buying items ‘a la carte’. Viessmann offers two options for pre-engineered solar thermal packages - the Vitosol DHW Solar Pack, or alternatively, th...

How radiant floors work
Delivery: radiant, forced-air and decentralized

How to design for thermal comfort in a home

...thermal bridging, sealed against air leaks, triple-paned windows, humidity control and properly designed heating, cooling and ventilation equipment , to name a few. Thermal comfort = efficiency and durability: The less heat that is lost through the building enclosure, the warmer it will be, and less heat will be ...

How to Fasten Cement Board Facing to slab on grade insulation
Slab on Grade

Finishing the exterior of an insulated slab-on-grade floor

...thermal bridging. What we decided on was plastic straps that passed through the cement board and that were anchored in the concrete. It did hold as planned, though there is more play in it than we ideally would have liked and if we were to do it again we would increase the amount of fasteners. Like many things, this ...

How to insulate basements properly

Best practices for basement insulation in new home construction

...thermal performance of basements, reducing heat loss and operating costs. It also helps reduce the chance of interior moisture issues by raising the temperature of the first interior condensing surface, the concrete. Below is a thermal image of the basement descibed above with insulation on both sides. The effective ...

Concrete and masonry

Gabion Walls - what is a gabion cage & how to build with them?

Gabion walls are retaining walls built by stacking stone in a gabion cage or gabion basket that can serve many purposes but are most often used to create tiered or leveled ground in gardens. They are rectangular baskets of metallic lattice filled with stones and their origin dates back to war times when they were er...

Hydronic heating

...thermal heat pumps Hydronic radiators and baseboard heaters will transfer heat in the same way as electric resistant heat sources. So for comparison shopping, efficiency of heat generation isn't as much an issue as installation cost and the lifespan of mechanical equipment. Worth noting that noisy baseboard heaters...
