hot water tank
« on: May 16, 2009, 07:48:15 PM »
Was wondering if there was such a thing as a type of water tank available to store water heated from a windmill?  I would have to install several heating elements which would be powered from my windmill.  Any help would be much appreciated, cheers.

www.builditsolar.com has info on many different types, some are like a large wooden tub with a plastic liner, others are large in-ground pits that are insulated and lined.


Is this for a dump load when batteries are full, or just a straight wind-heated water storage?

Why not just get a regular electric water heater.  You can swap out the elements for low voltage ones and dump to them.  What voltage is your system?

I am using a straight power to heat system for my windmill.  I have a hugh piggot type 1kw wind turbine which I use to heat storage heaters.  I altered the stator to have 9 coils of smaller wire with a lot more turns to give an output of around 100vac.  I have a series of electronic switches which turn on relays which put power to the elements.  basically as the wind power increases the more elements are switched on.  I assume it would be more efficient to have all the elements in one water tank then separated in different storage heaters?

I used a 1500 litre concrete tank that I rescued off a hill side. I dug it into the ground and poured urethane foam in arround it (4" min), spacing it off the bottom so that it was insulated from underneath as well. I built a deck with a hatch over the top. I used heat exchangers to heat it with solar (closed loop) and pumped the water direct through a wetback. There was also a heat exchanger to heat the domestic water (via a califont for backup) and water for the floor heating was pumped direct. Worked very well
