Solar thermal collectors

All about solar thermal collectors

...thermalsolar is useful, so we will outline the options. Evacuated tube solarthermalcollectors: Solarthermalcollector © Viessmann This is the most common type of solarthermalcollector 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

...thermalbattery?Thermalmass of any kind can by definition be called athermalbattery, 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 athermalbattery 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?

...thermalbridges: It is not only sensible to addressthermalbridging in construction, it is becoming law. Recent revisions to building codes have increased thethermalrequirements of building enclosures in many regions, including requiring athermalbreak. Contrary to common assumptions, the insulation value...

The pros and cons of thermal mass in buildings

...thermalmass 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 ofthermalmass in homes: Let's speak to the potential downsides ofthermalmass first - if a home is regularly left empty for several days at a time or if you keep a co...

Understanding thermal performance

...thermalresistance. 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 worldthermalperformance depends on a large range of factors including temperature, age,thermalm...

Product of the month: Solar water heater with overheating protection

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

How insulation works

...thermalbridge', and preventing it is known as a 'thermalbreak'. Heat loss throughthermalbridging When we mentioned at the beginning that these factors can work in conjunction, that is because the cold surface that results from the high conduction through wall studs and otherthermalbridges can absorb radia...
