Solar thermal collectors

Product of the month: Solar water heater with overheating protection

The flat plate solar thermal collector from Viessmann has a modulating collector to prevent overheating.   Solar thermal panels in cold climates are at risk of freezing in winter, so in the North, we use a glycol mix as a heat transfer fluid. This prevents panels from freezing but introduces new problems in the summer…

All about solar thermal collectors

Choosing the right solar thermal water heater system. What is a solar thermal collector? A photovoltaic (PV) solar collector converts solar radiation into electricity, but a solar thermal collector is much simpler than that. It refers to a device that collects heat directly from solar radiation. That can be as simple…

Air-heated radiant floors

A comeback for radiant floors heated with air tubes. 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 tha…

Solar panel reflectors

Using reflectors to increase the yield of solar panels

A study showed that reflectors on solar panels can increase their performance by up to 30%. The continuing drop in cost for home solar power generation has led to a dramatic increase in the rate of installations, for both residential and commercial use. Increasing the yield through reflection could make that an even m…
