Factory wholesale U-1A00 thermal wax actuator for thermostatic automatic water drain valve for Finland Factory Detail:
1. Operation Principle
The Thermostatic Wax that has been sealed in shell body induces expansion by a given temperature, and inner rubber seal part drives its handspike to move under expansion pressure to realize a transition from thermal energy into mechanical energy. The Thermostatic Wax brings an upward movement to its handspike, and automatic control of various function are realized by use of upward movement of handspike. The return of handspike is accomplished by negative load in a given returned temperature.
2. Characteristic
(1)Small body size, occupied limited space, and its size and structure may be designed in according to the location where needs to work.
(2)Temperature control is reliable and nicety
(3)No shaking and tranquilization in working condition.
(4)The element doesn’t need special maintenance.
(5)Working life is long.
3.Main Technical Parameters
(1)Handspike’s height may be confirmed by drawing and technical parameters
(2)Handspike movement is relatives to the temperature range of the element, and the effective distance range is from 1.5mm to 20 mm.
(3)Temperature control range of thermal wax actuator is between –20 ~ 230℃.
(4)Lag phenomenon is generally 1 ~ 2℃. Friction of each component part and lag of the component part temperature cause a lag phenomenon. Because there is a difference between up and down curve of traveling distance.
(5)Loading force of thermal wax actuator is difference, it depends on its’ shell size.

Shopping List:
1” copper pipe
½” copper pipe
Y-Strainer
Ball valves
Shut off valves
Circulator Pump
Thermostatic mixing valve
Relief valve
Water temperature sensor

Steps:
1. Turn off the main power switch on the boiler and the main water supply to the boiler.
2. Hook up a hose and water pump to the boiler’s draw off valve to drain down the water in the boiler. If possible, pump the water into a utility sink or extend the hose outdoors.
3. Find a spot for the new water heater. Use shims and a level to make sure it is sturdy and level.
4. Find a workable place to tap into the boiler to connect the boiler to the indirect water heater via the heat exchanger coil- preferably just below the water line to avoid any potential for sludge near the bottom of the boiler.
5. Dry fit 1” copper pipe connections from boiler to the heat exchanger coil input. Be sure to place a ball valve shut off at the tap point. Place a Y-Strainer after the ball valve to act as a filter and flush point. Use appropriate adapter pipe fittings, pipe dope and plumber’s tape to connect piping. Make sure all connections are level.
6. Before soldering any copper pipes, be sure to use sand cloth and flux on all the connections.
7. Solder the connections with solder and a propane torch.
8. Break the connection to the boiler draw off valve. This input will now serve as the return for the heat exchanger coil and a draw off.
9. Dry fit 1” copper pipe connections from the heat exchanger coil output to the input of the boiler. The pipe run should include a circulator pump, a purge valve, shut off ball valve and a second purge valve in that order.
10. Solder the connections with solder and a propane torch.
11. Break the connection to the main water supply into the boiler using a pipe cutter. Be sure to have a bucket ready to catch any excess water.
12. Dry fit ½” copper pipe connections from the main water supply to the cold water input at the bottom of the indirect water heater. Use appropriate adapter pipe fittings, pipe dope and plumber’s tape to connect piping. The pipe run should include a tee coupling to reconnect the new run to the boiler. Include a shut off valve after the coupling into the boiler. Extend piping off the middle portion of the tee coupling. Pipe should extend to the indirect water heater and include a draw off valve at the cold input. Additional pipe should also be connected to the thermostatic mixing valve.
13. Break the connection from the boiler to the main hot water feed into the home using a pipe cutter.
14. Dry fit the ½” copper pipe connections from the output on top of the indirect water heater. The pipe run should feed to a relief valve, the thermostatic mixing valve and connect to the main hot water feed into the home.
15. Solder the connections with solder and a propane torch.
16. Attach a temperature sensor to the indirect water heater.
17. Attach an electronic relay to the boiler.
18. Make the electrical connections from the temperature sensor to the relay on the boiler and the circulator pump.
19. Turn the main power switch on the boiler back on.
20. Turn the water supply valve back on.
21. Use the purge valves to eliminate any excess air in the system. You’ll need a bucket to catch the water.
22. It will take some time for the water heater tank to fill and heat up.

Paul Horowitz visited Google’s office in Cambridge, MA to discuss the SETI (Search for Extraterrestrial Intelligence) project at Harvard University.
Establishing an electromagnetic communications link across a thousand light-years presents unique technological challenges. In his talk, Prof. Horowitz visits some highlights of the science and technology of SETI — Do THEY exist? Is communication possible? What is the best way? Is this just completely insane? — and describes interesting searches his project and others have been doing.
Paul Horowitz is a Research Professor of Physics and of Electrical Engineering at Harvard, and is co-author of The Art of Electronics.
SETI at Harvard was supported in part by grants from NASA, The Planetary Society, and the Bosack/Kruger Charitable Foundation.
