Can it really be regarded as Eco-friendly equipment?

It has recently been found that an equipment went off an alarm of ERROR state and then does not proceed with water filling operation for bathtub. The ERROR code says, its temperature controller has got malfunction.
EcoCute: Heat Pump Water Heater, the equipment is called.
——-
Then, I contacted the service office of the manufacturer. The customer service personnel said that the production of the controller had long been stopped therefore its spare parts are no longer available. (Because the equipment is somewhat around 15 years old.)

Then, I attempted to pursue the service personnel further to seek an alternative temperature control device, saying “is that possible?”. Because, I am a sort of engineer and I understand that temperature control for water is not so difficult rather the technology, if I call it so, but anyway, is now a days of quite primitive and simply basic & matured one.

I am quite sure that it is not so difficult to find alternative parts and then assemble them together so that the same function is achieved. Of course, they have to make some adjustments so that the alternative can be installed in the very present EcoCute. That’s just a matter of engineering.
But the service personnel blankly said “No sir, that’s impossible. Now the whole system should be replaced with new one.”

But temperature controller! Such a simple device! How can the alternative device not be found? There must be some alternative applicable to original system through just a basic engineering work!!! I tried to insist on, but —–, in vain.

How much CO2 will be emitted throughout the whole process of full system replacement.
How much CO2 will be released to atmosphere if the temperature controller only is repaired or just replaced with new controller?
Then how the difference will be.

Apparently, in the former, more of CO2 will be released than the latter.
The manufacturer does not really practice sustainability, so I felt.

Maybe the company has to keep its personnel and increase its business performances; mainly the sales volume and profit.

My EcoCute looks intact in terms of its water tank, cabinet, piping, pump unit and electrical circuit, except for temperature controller.

in terms of CO2 emission.

Innovation, Economic growth, Conservation of the size of Economy, minimizing new production, maximizing innovation.
Too much minimize may bring society a state of boring or depression, then no innovation and high entropy.
But, too much “production” also may cause high entropy as well. And simply producing things does not necessarily mean innovation. If the similar products are continuously produced for a long period time, the state is considered as saturation; a kind of high entropy state.
However, this time, replacing the unit fully is valued than replacing or repairing the temperature controller though the latter should highly be valued from the view point of carbon free society.

I see, the manufacturer would say, “Sir, we do repair it if the model is not so old for which repair parts are available”, without referring to those two ECO cycles.
First of all, ecological cycle should always come first as it takes precedence over human. Ecological environment has created all the biological existence so far. Then after the dawn of human civilization, economic environment came. And both the ECOs have their own cycle respectively.
Just a few decades of cycle the manufacturer takes for its economy does not match with that of ecological one, which does have rather longer time-cycle.

Anyway, now is it possible to find further controlled manner between the two sides?

EcoCute, the equipment. To produce the unit, if you have scientific and technological knowledge, you can design, fabricate and manufacture the whole in a small workshop, the whole process will take so much time though.
Then, for industrial scale of production, you have to establish a factory and well organized people, energy of the process, subcontractors for parts production, help of transportation company etc.
Once that industrial scale production scheme starts working, you have to feed it with continuous demand for new units, maybe overwhelmingly larger than it really is.

Is it possible to reduce new production while continuing repair work so that CO2 emission gets significantly reduced?
Maybe reducing production of new units will kill the industrial scale production scheme.
Then, the point is whether the manufacture can thrive on only repair work and just a few numbers of production of new units. (The number is quite limited comparing with the beginning of industrial scale production.)

Cars. Overwhelmingly frequent model-changes are introduced. If I say, it’s daily, that’s not so overstated remark, I suppose.
Car makers have to keep its employees earned and to provide shareholders dividend while they are well aware of the state of saturation in terms of innovation, leaving CO2 in the air.

Can human overcome this paradox and guide its civilization to quite sophisticated and balanced state? Or else, is it a kind of unavoidable destiny of “Fall Of Civilization”?
