Hi friends,

I have been playing with a technology which looks very good in efficiency vs the good old oil filled radiators.
The heating element is made by conductive ink  :)
The goal for me is to replace my 400watt heaters for a 100 a 200watt system, which should deliver the same heat in the room.
I have succeeded in getting more inside info on this technology by doing some tests.
Do you have some interest in this? I am willing to share it. Maybe we can safe energy and money.
This system is fully DIY.

cheers
Steve

  • Build it. Power it. Use it.

Robert Murray Smith has quite a bit about that on his YouTube channel.  (He also uses conductive ink to make the thin low voltage type super caps.  And he found out that methanol is the best toner solvent, but I don't think he knows about the five gallon bucket caps.)  I personally like the cavitation drum heaters because they're OU.  I do think sheets like you're looking at will also block em when conducting biphasic energy.  So I may follow your lead.

The cavitation drums are difficult to make at home, at least for me.
I bought my ink from Robert. I am a great fan of his work.

I painted the ink in multiple paterns and underground.

The good thing is that it works on all non conductive materials.

The path for more efficiency brought me to ceramic tiles.

Also, if you make the surface too big, even if the resistance is good matching, the heat efficiency was not good.

So, so give away my current status is that i use ceramic tiles .
100watts do best on a 10cm by 10cm square.
The heat is very good and impressive.
Now, i will makae two squares of ink for a 200watt version.
After that, i will cover the ink with a spraypaint....

Slowly getting there

Correction....its 20cm by 20cm for a 100watt square heater.

Here a picture of the latest test.
Pulling 0.98 Amps at 230v.
Later i will modify this tile because the power goes in from the top and it should be from the middle of the two squares...

I measure maximum 150 degrees celcius on the top square and max 60 degrees on the bottum square.
So much difference!
So, it is needed to power them exact in the middle.

Where I live in the electricity is quite expensive so burning fuel for heat is cheaper, I can buy an electric heater for 50$ and it will give out as much electric energy I put in, the only difference with heating panels is the thermal distribution of the heat, so you end up heating the glass on the windows or the ceiling and all this heat goes to waste instead of heating the sofa or the bed, there's no other difference.

Hi Geon and Tektrical,

The thing is that you can buy for very little money electrical heaters. There are many of them.
I have a house full with them, or as alternative i burn wood.
The heaters are convector type heaters, so a metal structure filled with oil and a heating element in there.
It works, but my bills are soooo high, as electricity is very expensive.
I have installed solar panels with lit.battery banks.
It works, but when all heaters ( 400watt each and 9 pieces of them) heat at the same moment, the batterys go down quickly.

Then i saw Robert doing tests with conductive ink. He made heaters with them. Enable us to make whatever shape and form heater we like and if you build it smart, you can have a very efficient heater.

Again, i want to replace all my 400watt heaters for a 100 till 200watt type.
How does that look like?
Well, i did like 10 tests with different shapes, materials etc etc.
I learned how this ink works and what its maximum is.

I orderd yesterday new parts.
I am going to use a terrakotta tube (Ceramic tube) of 20cm long and with a diameter of 7cm.
One copper strip around the bottum and one around the top and ink in between.
That tube will get very hot, as it is ceramic.
I will place that ceramic tube in a 125cm diam plastic tube ( vertical)
In the bottum, i will mount a fan. Something similar you find in computers.
I will regulate the fan speed.
The heat will come out as the wind from the top.
I will add to the top a bend of 90 degrees, some the airflow will blow into the room and not to the sealing.
The bottum of the plastic tube will have feet and a hole for the air to get in the system.

I will probably make some pic,s of the build.
Replace 9 heaters of 400watt with 9 heaters of 150watts.....3600watts or 1350watts .....
Thats a third.
If it works........ ;)
If you dont try, you never succeed.
cheers!

So, here two pics of the new heater element that i build.

The tube is ceramic
230v and 0.78A it consumes
I measure after 5 minutes temperature of 115 degrees celcius.
When i blow some air thru and around the tube, the air is warm.
So far so good...
