One piece, rotationally molded polyethylene water heater
Australia:
|
 An
interesting Australian water heating concept that is soon to be available in
the US."The system is constructed of UV resistant high density polymer. The bladder and the tank are constructed in one piece using roto molding technology, no seams to leak. The secret to the system is that the pressure inside the tank and the solar bladder is gravity pressure only. There is a float valve that controls flow into the tank. A unique interior design promotes thermal siphon action from the tank through the bladder and back to the tank. The system is designed to deliver 9 liters a minute under gravity pressure at 15 feet of head. If the user desires mains pressure than a pump is added on the hot water line before the tap outlet. In North Carolina the unit generated 165 degree water during the summer and 140 degree water in the winter. Performance will vary depending on the latitude the unit is located at.
There is an electric 240 v heating element and adjustable
thermostat inside the tank as a back up heat source. The unit also has
a gas back up heat option available. There is a 10 year warranty on the
tank and bladder and a 5 year warranty on the heating element. The
manufacture claims a 20 year or more life of the tank and bladder.
Empty the unit weighs 230 lbs full the unit weighs 900 lbs. The foot
print is 5" 5" x 7' 4".
The design of this system is different from the traditional thermosyphon water heaters in several respects, so be sure you understand these differences, and that the unit is suitable for your situation. |

Imported Thermosyphon Solar Water Heaters One example:
|
 There
appear to be a number of these imported thermosyphon water
heaters with integrated storage tank appearing for reasonable prices.
This may prove to be a good option for cost effective solar water heating.If you have one of these, and could share your experiences, please let me know. |

| Davies Craig 12volt EBP pump
One potential source:
|
 This
is a 12 volt pump with magnetic drive that is meant for pumping high
temperature coolant. Solar heating is listed as one of its
potential applications. Does about 3 gpm at 1.3 amps (12VDC). One user of this pump posted this message: "The Davies Craig Booster Pump is a 12 Volt DC magnetic drive pump that will handle water temps up to 120C. Draws approx 1 amp @ 12 volts, has a life in excess 10,000 hours. I have had one running on one system for over 2 years now with no problems, circulating water through 7 sq meters of panels located approx 8 meters away from HWC, connected by 15mm copper pipes. It is not suitable when in a mains pressure loop, i.e. pressures in excess of 50 psi as is constructed of a type of plastic." It is reported to have about the same pumping capability as the ELSID20 pump. |

Froma about $50. LVM specification |
| More Beer Pump
|
 An
interesting pump made for making beer. Good for high temperatures.
May have solar application? Magnetically driven. Too bad its not
DC so that it could be powered by PV, but its might be a cheaper substitute
for a bronze casing Grundfos or Taco for open systems?? |
| PC Cooling Pumps One potential source:
|
 These
pumps were developed for water cooling of PCs. They appear to be high
quality, have magnetic drives, and are designed for fairly high temperatures
(typically 140F). Many of them have good pressure head capability. They might be a less expensive alternative for small PV powered systems -- $40 and up. |
| Linear Current Boosters One of many potential
suppliers:
|
 Linear
current boosters hooked up between a PV panel and the pump it is driving
match the two together more efficiently, and prevent the pump from being
exposed to out of range voltages. |

water heating systems.
about $130 I have one of these, and it has done well. |
| Steca Differential Controllers |
 Steca
differential controller. Has the usual features, and a nice display
that shows collector and tank temps as well as pump running.I have one of
these and like -- especially the display of temps. |
| DC Powered Differential Controller http://www.arttec.net/dtc/index.html
|
 This
differential controller that is powered by DC would allow a PV powered pump
in a solar water heating system as an alternative to just directly powering
the pump from the PV panel. Some feel that this would allow more
precise control of when the pump comes on (for instance it would avoid
turning the pump on when the storage tank is hotter than the collector
fluid). |

to hear about it. |
|
Thurmalox Selective Surface Coating
http://www.solar-components.com/batchheat.htm
|
 This
is a silicone based selective coating that comes in a spray can. If
this works, it might be a good DIY alternative to the selective coatings
listed above. It is claimed that when applied at 0.5 mil thick, it has an absorptivity of 0.96 and an emissivity of 0.52.
