Hello, if you have plenty of solar collectors for heating in mid-season (spring-autumn): how do you do in summer, it overheats all the time? even with a buffer tank? the safety valve spits towards the waste water, and the automatic filling unit "cools" the ins ...

Hello, The solar gain in autumn is random but when it is possible, whether for DHW or heating, this is where we measure the savings achievable. The surface of the sensors is also to be taken into account for heating, which is much more demanding. It is true that at this moment ...

Good evening, The power of the heat exchanger, therefore its ability to transfer calories, depends essentially on its surface. In the case of corrugated stainless steel, there is also the turbulence created in the tube during the circulation of water. So single or double exchanger, regardless of when ...

Hello, For 3-way recycling valves, or temperature reading or thermo ... etc, it must be able to pass a certain flow and above all, the opening occurs from a certain temperature, a bit like a calorstat on a water-cooled heat engine. On the other hand, on the ...

Hi Jo,

Uh, what is alternative heating for you?

230V AC Nuclear?

A+

Hello, Is an automatic operation of the Wood / Fuel changeover possible (when more wood, the fuel takes over) ?? No valve to open or close manually if possible. Yes, we use 2 separate circulators or 1 circulator and a motorized zone valve. To find out if there is ...

Hello, To summarize my impression of what I read, A lot of talk to explain that we place a CESI in series with a boiler with instantaneous hot water production. None of the manufacturers mentioned produce solar equipment, so obviously, you have to find a trick to ...

Hi mi16, I recommend a single exchanger from top to bottom. The same coil is used for both the load and the heat discharge. It's just the direction of flow that differs. Take a look here: http: //www.apper-solaire.org/Pages/Fiches/Ballons/Echangeurs%20instantanes%20ECS%20en%20i ...

Hello, The operating agreement with ERDF is in principle a mandatory formality if we want to inject into the network, even domestic, but for very small powers, it is clearly dissuasive. To be in the nails, at least as regards the material used, the inverter ...

Hello, Bravo once again to the Americans who "invented" this magnificent new sports concept. Okay ... so humans are starting to understand and practice this concept of dynamic glide, but it was the birds that actually invented dynamic glide because they pr ...
