Re: Cumulus gas consumption monitoring

Or a hot water leak? 9 kWh is the energy to heat 150 liters from 10° to 60°...

You can try to turn off the gas for 24 hours without using DHW, and see how much the temperature drops, that would allow you to calculate the thermal loss of the tank.

Re: Filling boiler HS France innova 30

Hello, The boiler is an HS France Innova 30 with a 1500 liter HS France KSTS-2 tank. Yes, this tank will also make domestic hot water but without using the coils. Dede2002, you have understood how this balloon works, do you think I can take hot water (heating) for the m...

Re: Filling boiler HS France innova 30

Why make it simple when you can make it complicated?...

For my part, I wouldn't have done it like that, but we're not going to argue about it :)

Re: Filling boiler HS France innova 30

Hi, Ok I understood the principle, so in the summer you are going to heat the 1500 liter tank to make DHW? I suppose it is well insulated, For if it was simple, with the high power of the wood boiler, the water from the balloon is circulated in the boiler, the coil would have difficulty following...

Re: Filling boiler HS France innova 30

Hi Boumbocox, I don't find your diagram that separates the two boilers logical, do you have two expansion tanks? The balloon is only used to store the energy of the wood boiler, at high power, and send it back to the radiators. The gas boiler directly heats the radiators, when the boiler...

Re: Russian Gas: Gazprom Putin's Bomb G (Arte Thema)

Yes, for the plural of bar, but I find it hard not to put "s"; we don't get over it... :oops: It was only a post scriptum, even with an "s" the message is intelligible... But unlike the mistakes we all make here and there, this one this is almost systematic...

Re: Solar inverter on generator or on battery inverter?

For the drawing, I was kidding...

You just want to connect two circuits with a common point, nothing to do with the neutral.

But my question is serious. :)

Re: Solar inverter on generator or on battery inverter?

Three 220 V = 3 phases at 127V with respect to earth or neutral (if connected to earth) = 127 * root of 3 between 2 phases = 3 * 220 V Mono 220 V = 1 phase at 220V + 1 neutral So I can wire my sorting with a mono in PNP or NPN (and variants) = 2 phases at 230 V with neutral between 2 pairs 0 on the 3...

Re: Solar inverter on generator or on battery inverter?

Hello, What I said at the beginning, the difference between a generator and an inverter is that the inverter is not reversible, a generator would have mounted the towers, so the frequency (with or without breakage, it burns out a generator as quickly ...) There's something I don't understand, it's that you say avoi...
