kids browsing the internet I came across this study concerning a new technology for the development of heating systems and cooling of buildings through this particular type of coat, which provides a series of serpentine to heat or cool the masonry from the outside.

how do you comment? :smile:

interesting, but if a tube loses?

he he well this can happen in any type of irradiation plant at low temperature. . However, we admit to doing a good plant, it is actually much more shipped and cheaper work, but my perplexities are other, like the fact that the radiant source is beyond the barrier of existing walls. . .

it goes well that there is then the coat, but is it not that the efficiency is visible?

and then, if one presumes to use air as a fluid and not water?
 
I am not convinced of this solution.
the heat pump, even if in class aa, consumes so many kwh that the condo in addition to the very high communal expenses, it would also suffer from this.
The plant costs so much.
maintenance. ..when they come out, they peel you...when you wanted this solution.

of solutions for energy saving there are many.... but the costs are very high for private and without incentives. When a family starts to benefit?
The children would take a new house... paying a mortgage... besides the fact that you don't have to wait for your parents to die for it, and when you get it or sell it or rent it to some extra... seen that if you have to make the coat you do it to an old house.

There are so many things to look at.. .not just those two poor calculations presented on pdf.
 
we say that the concept of low temperature plant is exact.
I knew for the first time plants of this type in 87, it was floor plants and they were already working very well.
as the water of the circuit was 45° (instead of the 70°-75° of a traditional plant) the saving was really remarkable.
let me puzzle the fact that you apply a plant on the outside, you have to cross the whole wall to convey the hot/fresh and you have only 6 cm of insulation outward .... Mah.

That's what I thought. But at that point I would make a coat more often and take advantage of the laying system to create natural channels between wall and coat, where to flow air conditioning (hot or cold). At that point the costs would fall further.

Of course, air has less potential in transporting calories (or refrigerators) than water, and what does that mean in theory?

that you need to circulate a lot of air and you have to have a higher radiant surface, as it has a much lower thermal conductivity than water.
I think it does not agree from the economic point of view (the air system instead of the water system).

Sure. I would be interested to understand theoretically how much it costs extra to transport same calories with air and with water.. I mean, are there any concepts that have already been devised?

the thermal conductivity of dry air is 0.026, that of distilled water is 0.6.
by making the bills serve 23 litres of air to have the thermal conductivity of a liter of water.

interesting. then now (always remaining on the accounts of the servant) just understand how much it costs to move ventilating 23 liters of air and pumping instead 1 liter of water, right?

and above all what kind of boiler you have to use because it goes to air instead of to water:biggrin:, because if you use a heat pump, it is worth putting hot air directly into the environment.

However, in this way we create those air movements that would be desirable to reduce as much as possible, because they convey dust.

then it would be much more difficult to create a closed circuit that always treats the same air. .

I have in the house a conditioning system with heat pumps and I have to tell you that when I use it (rarely) it is not bad.
each machine has its dust filters, and when you turn on it heats it with an impressive speed, much better than traditional heating.
In fact I was thinking of installing a photovoltaic system to use as little as possible heating with wood and pellets (under this point of view I am equipped ... I have eliminated almost entirely fossil fuels).
 
What moves me is however the fact that making an air circuit is much safer technically and cost-effective in the realization compared to the hydraulic circuit, the lower efficiency the discounts with a lower initial price.

It should be done well, however, which does not seem so simple..:biggrin:

I also thought of using the wood to heat the air, and put the heat pump as an alternative or integro of energy.. the wood especially because I love to watch the fire
 
the water circuit is no problem, I have seen so many around and with the materials that are there today, they last you more than the house.
plastic pipes (mi sempra polypropylene) and not old copper pipes are used.
the plant costs you a 20-30% more than a radiator system (always it is a new plant) but recover them in a few years with energy saving.
I also think there are 55% incentives if you respect certain conditions.
 
It is true, but I was referring to the type of fluid to be circulated in this active coat, if a circuit of water takes hundreds of meters of pipe and many fittings, and systems of infinity etc., instead the air circuit could be realized only for how mountains the panels of the coat, would not need anything else (other than the fan to circulate the air).
