Hello,

In the search for a micro-cogenerative boiler fueled with wood I came across a company from Switzerland offering a small model quite powerful:

To size it I would need to know more. I can not reach the company, maybe someone from this forum know this model and could inform me.

I would need in nominal mode the maximum and minimum temperatures of entry and exit of the boiler, know its performance and its consumption.

merci beaucoup

Hello,

Beginning 2010, Eneftech Innovation moved to Nyon in Switzerland. It can be reached at 0041 22 994 04 20 or by mail: info@eneftech.com.

In addition, his new website has been put online. It now contains the operating characteristics of its devices,

Hello,

I am trying to relaunch this subject because I am waiting for a quote for a Pellet boiler and a water / water heat pump.

- Have some of you been able to install micro CHP with a Pellet boiler or an 2010 or 2011 heat pump?

- If not, is it possible to be able to couple a cogeneration module to a boiler or a water / water heat pump later, ie to invest in a boiler or an evolving heat pump?

I am surprised that this theme has fallen into oblivion, I can not find a message later than 2009 on this subject. Is there an omerta?

Looking forward to reading you !

As much as I understand the use on a boiler, the mounting on a cap leaves me perplexed (to say the least) ...

There is the use of the effect Seebeck or Peltier inverse to make electricity from heat on stove or stove with this type of refrigerant module on econology posts to see !! (yield less than 10%) .
Finally on PAc, it's not understanding the basics of the principle of Carnot!

Thank you for the answers ... As much for me on the CAP, I return to my studies of continuation ...

So I invest in a boiler that can evolve by adapting a cogeneration module in the future (2012? 2013?)

We must distinguish the refrigerant circuit and its use in PAC.

It is possible to use a refrigerant circuit to produce a movement from a cold source and a hot source: just use the gas expansion phase: this is what Eneftech offers, but others are working on the subject.

On the other hand, using the hot outlet of a heat pump as a hot source of a mechanical generation refrigeration circuit is not of interest ...

not very clear, if I understand, it is to use the compressor in the opposite direction as a reversible motor operated by the relaxation of the gas between the hot and the cold !!!
A steam engine or turbine has been doing this for a long time !!!
With a reversible structure we make a fridge !!

Hello,

Yesterday, a person came to help me make my choice and we discussed the following topics that are all possible at home:

Micro CHP:
- No interest for the individual because the boiler affects part of its consumption to the electricity production so it increases the latter.
- With additional installation costs to prevent voltage drop in the electrical installation.
- Last argument: This is new and it is necessary to wait for the returns and to couple a module a posteriori is risky because not integrated.

Pellet boiler:
- The yield is about 95%, possibility of coupling with a solar or thermodynamic balloon to relieve the boiler.
- Mechanical maintenance but always remains the problems of fouling.
- Cost at Kw / h cheaper than electricity

aquathermal:
- Tablecloth close
- Efficiency with 5 COP
- But risk of clogging of the filters and lack of flow on the sheet may cause the pump to dip into the sand or not to be fed.
- Maintenance between 150 and 300 €

Geothermal Soil / water (his choice):
- COP 5 performance
- Clean and moderately priced maintenance 150 € to 200 €
- The increase in the price of electricity will be more easily cashed than the increase in the cost of pellets.

It's up to me to make my choice.

Commercial hype that mixes things with hypocrisy !!
