2 Objectives At the end of this exercise, you will be able to:

3 Create and configure a macro Edit a macro Execute, test, and troubleshoot a macro

4 About This Presentation Let’s put the sun’s heat to practical use. let’s use solar power to automate a cabin to get hot water. But first, we need to know a few things about it.

5 Why Solar Water Heating? Second highest energy need The energy is free Can be inexpensive to install for a do-it-yourselfer

6 But First, Let’s Save Energy Install low-flow shower heads Turn down hot water heater’s thermostat Insulate hot water tank and pipes

7 The Four Basic Elements of Solar Water Heating Systems: Collection Storage Distribution Control

8 Solar Hot Water Collectors Passive Active Difference is - Passive collectors need no pumps or electric controls

9 Passive-The Simplest System Courtesy Thermo Technologies Place a solar blanket or other type solar pool collector over a swimming pool.

10 Here is an example. It can even be used to warm the earth. Courtesy Thermo Technologies

11 How Warm Will Something Get? That depends on where you live. Courtesy Thermo Technologies

12 Courtesy Thermo Technologies Another Solar Heater-Tubes

13 Put Them On a Rooftop Heat Light And virtually all our weather Courtesy Thermo Technologies

14 Or in the Snow Courtesy Thermo Technologies

15 A Solar Collector

16 The evacuated tube collector is the most efficient.

17 The Batch Solar Collector Courtesy U.S. Department of Energy

18 Using A Collector Courtesy Thermo Technologies

19 Storage Courtesy Thermo Technologies

20 Solar-heated water usually gets stored in a well-insulated storage tank. Courtesy Thermo Technologies A B C

22 Distribution-How To Move The Heated Water Pipes Tubing Valves Connectors

23 The Heat-Rejection Loop Courtesy Thermo Technologies

24 Control What makes things go right? What if they don’t? Courtesy Thermo Technologies

25 The Temperature Controller Courtesy Thermo Technologies

26 Controllers can be sophisticated. Courtesy Thermo Technologies
