I know of another brand for larger homes, the Metal Dynamics Gourmet Cooker;

Here is a product from New Zealand that I saw an ad for on our recent holiday there;

The brand of the hot water tank is Beazley. It is a salvaged unit from a solar hot water system that was damaged by hail. We got it cheap from a local solar hot water supplier that did the replacement job.

Installing a hot water system is a job that I first attempted myself. I failed several times to get it working to my satisfaction. I redesigned the system and got a qualified plumber to come for the day with all the tools, parts and experience we needed.
I got several quotes for the work once I knew what needed to be done and a rough estimate of the lengths of pipe etc.

When designing a system and it’s placement there are several key principles.

1: The distance between the solar hotwater panels or the wetback on the stove must be as short as is possible.

2: This connection needs to be a continuous (rise for hot; fall for cold) with minimum bends. This prevents any airlocks forming and a freeflow of the thermosyphon.

3: There must be a way for pressure to vent to the atmosphere.
If you are on mains or pump pressure you will need a special valve that is specific to the pressure capacity of the tank, the heating unit and the water pressure. If you gravity feed the water, a shepard’s Crook that rises higher than the source will allow the any steam to escape. This prevents pressure build up to the point of an explosion.

4: There is a definite order in the vertical placement of the elements.
In our gravity system;
The vent is at the top,
Then it is the main header tank,
Then it is the hot water tank,
Then it is the solar panels or wetback.
The outlets must be below the hot water tank.

5: Run a short a length as is possible from the tank to the hot water outlets. This prevents the wasting of water while someone stands in the shower waiting for it to warm up. It is only three meters from our hot water tank to the shower rose.

I am interested in information regarding the setup of your wetback hot water system. Could you please let us know the brand of the stove and the brand of the hotwater cylinder. I have had trouble sourcing a suitable hot water cylinder myself, although i already have a woodburner and a small block of sustainable firewood.

glad to hear the good news regarding your rain and water storage, wise words to refer to it as treasure. Kind regards J Kirkland (NZ)
