is the circulating tank insulated to keep the water hot all night or does it cool at night, making for cold night time showers, brrrrrrrrrr

[VillageGoneGreen]

@flamedrag18 Sure it is! around 3" thick

[flamedrag18]

@VillageGoneGreen but will it keep the water heated overnight and early morning?

[VillageGoneGreen]

@flamedrag18 YES, it's design that way.

[electronicdawg]

Is it good to bath with antifreeze?

[VillageGoneGreen]

@electronicdawg What??? the glycol (antifreeze) does not touch the domestic water.

[davidshortt88]

@flamedrag18 It looks like a preheat-er if the water cools the primary water heater heats the water.

you dont need to heat hot water

[hogwildgardener]

How do you keep your pipes from freezing that run from the tank to the house? heat tape?

thanks! should one use pex pipe or copper for the outside plumbing?

@victim0001 That's how I understand it too

[victim0001]

It's too bulky, nobody likes a huge tank next to their house.

[czech27]

so, is the first system a closed loop type and the one on the house is open loop?

[VillageGoneGreen]

@leaualorin NO DON"T DO IT, Glycol wont corrode your pipes and it's designed to balance the temprearture from hot to cold

[ntomata0002]

@electronicdawg It's awesome, you can then walk to the snow naked and do not feel cold at all...

[roadlessgraveled]

You would typically put this system "in line" with your existing system, and you always have hot water. The solar heated water fills your existing water heater instead of cold water. If it is above the set-point of the conventional water heater, it won't add any heat...if it's below, it adds enough heat to raise it to the desired set-point.

@electronicdawg the water in the pipes never touch the water going to your home. it works like a radiator, the house water runs inside the barrel in a pipe network while the water surrounding it is separate. how it heats the water is by controlling the density, the cold denser water sinks to the bottom of the outside pipes while less dense hot water floats up into the heating barrel, the water in the pipes and barrel can contain antifreeze since it's only surrounding the home pipes, not joined.
