Otherwise, I would send information on the events in which I participate as the day of future vehicles to be held at Pôle Mécanique de Haute Saintonge in June 2015 ...

the price of vmc single stream makes my hair stand on end! although expensive for not much
an original solution: take a soufleur of electric dead leaf: This is too powerful, but it works very well to reduced tension, gender or 12V 24V, and low speed it becomes very quiet ... and performance at low speed has better power rating
for other souflerie, kind of heating air intake wood I use the vacuum cleaner to be struck: the low voltage has also fueled it becomes silent and high efficiency
for those who want to reduce the speed of the fan induction motor there are now dimming frequency inverter type of phase but making a kind of two-phase to single phase motor capacitor: a phase on the primary winding and the other phase of the winding capacitor

alas it is a bit expensive for a vmc, hence my preference for the dead leaf soufleur low end or you can reduce the speed by a single transformer

Here's a little back from my weekend tests.
I tested my interchange with easy flow vmc 1er price.
1er test with a VMC with action fan of this style:
Inconclusive: here blew frankly not strong output of 6m sheath, and too noisy (to my taste) .Pas enough pressure ...
So I returned to the store (and I got pay ... telling them that it was not as terrible vmc ) Then I bought another in a 2ème teaches, but this time it was an action fan (dawn), like this:
And there, it's nickel! breath here well after sheath and much more silencieux.Cà goes smoothly with filters 2, 1 1 input and output of the insufflation.
So I will continue this voice

heat pump air more water vmc turbofan
Hello,
New on this forumbut since reading for a while, I would need your opinion.
I live in a house that I'm trying to improve little by little, and the first thing I do is to turn my gas boiler friquet hydro 1998 comfort with these 80l for DHW propane, and I replaced within two or three weeks (over heating meantime) by an air heat pump water STIEBEL ELTRON wpl25as that will power both floor heating and dHW.
The question I ask myself, is it possible and worthwhile to use a deflection of the hot water produced by the heat pump and pass through a water to air heat exchanger double flow VMC I plan to make myself ?
If this is indeed possible and interesting, as my installer did not plan it in unscrewing counter pose, how to make this possible without jeopardizing the security of the installation?
Thank you in advance for your answers.

- use hot water to heat the incoming air (in this case, I think it's unnecessary because it duplicates the floor heating)
- heat recovery from the exhaust air to the CAP (on a VMC double flow, there is not much to recover).

So what you would do is no more or less add a radiator on your heating system.
Instead of heating the parts as with a conventional radiator, you would warm the air in the VMC.
2 cases:
A / You put the hot water coil (the term used), on the arrival of the new air BEFORE VMC.
This will indeed preheat air or eliminate icing of the heat exchanger of the VMC cold weather.
I think it will also decrease the efficiency of the exchanger of the VMC ...
B / You put the hot water coil on the air blown out of the VMC, ie after the exchanger has done its job.
So you do not impacted the performance of the VMC and you add the calories of your heating coil in the VMC circuit.
The hot battery option exists on most high-end CMVs, it seems to me that it is configured according to the "B" scenario.
For this to be profitable, it is necessary that the thermostatic control of the heating coil is set correctly ...
The hot battery will also cause loss of load aerodynamics and can generate noise.
It is imperative strictly insulate the hydraulic lines (not to mention the slopes and traps) and the casing of the heating coil.
Ideally, install a motorized damper for the summer, the air does not pass through the battery.
In short, it is a feasible business but requires instead a lot of work, money and a lot of rigor ...
Any odd and you will lose more comfort and energy than you hope to win.
According to the network type as your installer should take, it is simple enough to ask him to make a reservation for the installation of an additional radiator (2 taps on the heating network) on which it will connect 2 isolation valves 1 / 4 tower and 2 plugs (50 100 to max € TTC labor included, no for € 20 equipment).

I think it works, but I do not see the energy interest compared to send the same hot water floor heating.citro wrote:B / You put the hot water coil on the air blown out of the VMC, ie after the exchanger has done its job.
So you do not impacted the performance of the VMC and you add the calories of your heating coil in the VMC circuit.
And to the extent or the heating source is the same in both cases (CAP), I see no economic interest ...
