Re: Siphon lift pump, free water pumping

Hello, I'm digging up this topic with an idea:
would it be possible to use a thermosiphon to make an elevator siphon work and thus pump water thanks to a temperature difference?
Here's the schematic I'm thinking of

Wood wool roof insulation: wood structure or placo rail?

Hi, can any of you advise me on the choice of the structure to use to maintain wood wool (80mm between rafter + 180mm between purlins) under the eaves and to support the interior facing (OSB3 without 12mm formaldehyde in the absence of a livingboard from my supplier). I ...

Re:

In the past there was indeed no VMC because the houses were not insulated […] So the walls no longer "breathe", it was necessary to find a stopgap and it was the VMC. […] It was their own insulation, very permeable to water vapor and humidity-regulating. I more so, the problem of the ...

Re: [Study] Solar Steam Pump

Hello, Hello Joe, Where have you been since this study. I bought an old (early 100th century) hand pump, made of cast iron. XNUMX €, a restoration blow (change of seals, rust block, linseed oil) and it works nickel. With mulching on the vegetable patch, that's enough for my needs. I don't forget ...

Re: [Study] Solar Steam Pump

Thanks oli 80, there doesn't seem to be any doc on their site (they put forward photovoltaic systems) but the proof is there that it can work. In view of the flow rates obtained compared to the one I have (I do not want to dry out my pool so I must not pump more than ...

[Study] Solar Steam Pump

Hello, The context: I have a basin fed by a source with a flow rate of 1l / min. This basin is located 40cm below the level of my vegetable garden, hence the need to pump in to water. The idea: To manufacture a solar collector capable of producing steam to operate a piston pump ...

Re: Boiler connection to central heating

Hi, I signed a quote for a 15kW hydro log stove (+ 9kW in the air) + 500l tank + valves and circulator + flue gas + installation with connection to the fuel heating circuit for 8000 € (-1000 € of credit d 'taxes). If you say that you have it for 5000 € without installation and without buffer tank, it is ...

Insulation of a counter-partition in Brick Raw Earth

Hello,
I am about to mount a bulkhead in mud brick in the corner of my living room that will house the wood stove.
I wonder about the insulation to put behind this wall, knowing that the wall is in blocks. :?:

Thank you for your opinions ! : Wink:
