Solar Water Heating Systems for Hot Tubs?

Surfing the internet this morning I came across an interesting link: http://solarhotwater.cliknsav.com/solar-thermal-hot-tub-heating-system-hd/.

Adding a small solar hot water system to your hot tub can help you reduce your cost of energy over the long run. How much depends on where you are geographically and what incentives are available in your area.

I thought the author did a nice work on the video. I know animated renderings take time to create.

It certainly would have been helpful if the author had included the audio for the purposes of clarification. For example, it appears he has his heat transfer fluid flowing through the collector from top to bottom. This is significantly less thermally efficient than filling the collectors from bottom to top.

I see little design flaws like this all the time. Helping resolve such problems is the goal of my blog. I touch on some positive design attributes the article found here.

Please leave your feedback!
