Consumption in Kg / h of boiler VMW 242 2-3 of 24KW

Good! I have a Vaillant VMW 242 2-3 that says it has a heat output of 9-24KW. I imagine it is set to full power, what gas consumption would it have at the time? I just want it for ACS. With my accounts I get about 2Kg of gas per hour, that is, a butane bottle for 6h of use, have I done the numbers well? Link to boiler characteristics: LINK Thank you!

Hi EDUGIMENO: In principle the calculation is well done 2 kl gas per hour, that counting that the boiler is operating at maximum power. If you modulate you will consume less, at minimum power you are consuming 0.75 kl per hour. LUCK

Thank you. The truth is that with the current setting heats up too much (except in winter but I only go there in summer), is the modulation setting something I can do myself?
Another thing, since I put a separate question but I don't know why but it was erased: It's a house that I only use for 2 months in the summer, I want to unsubscribe from the current channeled propane gas and use bottles. 1) If I use butane, should I change something in the boiler? Something I have heard of different gas pressure, but I don't know if it is a matter of the regulator that carries the hood or inside the boiler
2) Are there 12kg bottles of propane?

The modulation is handled by the boiler plate, the minimum is 9 and the maximum 24, depending on what you need to heat, modify the amount of power.
by the network deliver propane gas natural gas ??? If it is natural gas you have to change the boiler's iyectors, apart from some you have to change plate parameters and you should regulate gas valve.
If it is propane, you should not change injectors, if you check gas valve regulation.

No, on the network it is now Propane, it is assumed that this boiler does not need changes between propane and butane.
Anyway I am looking for if in my area they supply Propane cylinders in 12.5Kg, if so it would be all easier.
I understand that the way to handle the modulation of the ACS would be to directly lower the green control of the housing that indicates the temperature of taps, no?
Thank you!

If it is propane, you should not have to change injectors, you have to put a price regulator on the cylinder, but also measure pressure on the boiler's water valve, according to the temperature you ask for hot water and the amount of water that you pass through It is automatically regulating the power.

Oh and when you say "check gas valve regulation" do you mean the pressure regulator that carries the "hood" of the bottle or something else? Although if I end up carrying propane cylinders instead of butane, nothing to touch, right?
