In fact the orifices of the boiler and ball are provided for iron,´. ok, you are talking about fittings in 40, whereas it is 42,3 in principle the 1"1/4. So what is the tube? what is its method of assembly? And in tapped outlets in 1 "1/4 the 40 is going to have a crazy game. Do...

to pass 30kw over 12m, an inside diameter of 30 is enough. Afterwards, depending on the type of pipe, you take the diameter just above. Thus in copper of the 35, in black iron of the 42.
You have coins in 40, so I assume copper? it's largely enough.

we change this stone when a piece of about 2cm is missing. Condensation: This is a reverse flame boiler with assistance from a fume extractor. The fire of such a boiler must not be smothered. I adjust this type of fire to obtain a fairly white but not blue flame (air ...

yes, that had to happen. With people who heat themselves at 24° to be able to be fine at home, those (including town halls) who heat with pellets instead of insulating, the greening of coal-fired power stations by adding pellets, and tax incentives it was run. I r...

Ah I forgot ...
The DHW tanks of gas boilers are often very small, in particular on wall-mounted boilers, the DHW heating being almost in instantaneous mode.
There is no point in wanting to do chess with wood in this case.

Thank you both !
Indeed, by pulling hard I took everything out and I could see that it is not an exchangeable bulb. Everything must be thrown away!
I can just try to separate the metal hubcap and the plastic parts to make recycling easier.

Hello and best wishes!
Does anyone know these led spotlights from Philips?
this one is hs and i cant seem to disassemble it. I tried to twist the ring that holds the bulb, to no avail.
thanks in advance

Yes it works, and yes, your boiler will be a radiator. But (there is always a but: mrgreen :) in general there is a permanent draft in old gas boilers, so by this natural draft you will heat the birds. The overall yield will therefore be degraded compared to a branch ...

Hello,

no, I do not work on the gas boilers and not in the 68 either. Especially since I no longer work. Sorry.

Hello,

- remove the plastic cover to locate the 2 wires which supply the motor. (There may be others, connected to limit switches)
-connect them to 220v. The engine should be running.
-interrupt the current and the motor must return to the rest position under the action of the spring.
