Piping commercial pressure glycol or drainback solar projects
When piping together large commercial solar arrays, there are some basic rules that will make installation flow much more easily. Continue reading
As temperature rises, so does interest in solar for pools
It’s the season to size solar for pools. Here’s the formula to do that for your own swimming hole. Continue reading
When a recirc loop meets an anti-scalding valve in a solar thermal system
Sometimes the anti-scalding valve can cause problems with a recirculation loop in a solar thermal system. Here’s how to pipe a mixing valve so the recirc loop always performs. Continue reading
This design for a light commercial thermal system is effective, simplified
Looking for a design for a light commercial solar thermal system that actually uses solar energy to heat hot water? Here it is Continue reading
Is your drainback tank sight glass cracked? Here’s the solution
Here’s an easy service tip for those whose systems use an HTP drainback tank – specifically on the maintenance or replacement of the sight glass. Continue reading
Today’s solar thermal options are cheaper, more efficient to drive
Like automobiles, solar thermal designs have become sleeker and more efficient over the decades. You wouldn’t expect today’s performance out of a 1964 Mustang, just like you wouldn’t see high efficiency and lower cost using an outdated solar design. But it’s done all the time. Continue reading
More bad designs: Kicking solar in the shin
Bad solar-thermal designs not only cost customers money, but can do permanent damage to the solar industry we all love. Continue reading
Dear 1970s: Solar design has long since passed you by, get with it in 2012
1970s-era solar thermal designs are still common, although today’s technology makes solar hot water more efficient and less expensive. Continue reading
Extra large solar tanks now part of our lineup
For that hard-to-fit commercial solar job: Extra-large volume solar tanks. HTP now has them. Continue reading
Sizing solar thermal for a dorm: Here’s an example
I’m most often asked how to size a solar thermal system: the number of collectors and tank size, for example. Here’s an example of how to design a solar thermal system for a larger project — in this case a college dormatory. Continue reading
New HTP app saved me a climb down the ladder
HTP’s new app includes all product installation manuals, specifications, image, drawings and more. It could save you from an extra trip down from the roof. Continue reading
Do you need to worry about roof penetrations made for solar collectors?
One of the most penetrating questions of solar thermal is how to attach the solar collectors to the roof. It’s one I get asked quite often: Is it safe to make those holes in my roofing material? There are many ways to ensure a weather-tight seal, whether using a flush-roof mount or an adjustable mount that tilts the … Continue reading
Monitoring will ensure solar thermal systems perform at their peak
Some solar thermal systems are under performing or simply not working because of improper design or installation. The solution may be to monitor all systems to see just how much non-renewable fuel is being replaced by solar. This will help us catch and diagnose the non-performers early on. Continue reading
