Solid fuel C/H safety devices, & exp tanks

[Plouasne]

Just trawling the net for somebody on a French forum, and came across these, thought that some of them might be of use to somebody who is doing solid fuel central heating, and wants to cover their back, if there is a power cut or pump failure, when the boiler is well alight

What is the opinion of the honourable "dinosaurs"

can anybody translate?

sorry to crash thread, but any opinions on these would be intresting:

Solid fuel is great in theory, the heat is incredible. But takes alot of work to keep them going if they are your primary source.

Solid fuel is great in theory, the heat is incredible. But takes alot of work to keep them going if they are your primary source.

For solid fuel boilers, wood pellets is the way to go in my opinion, almost no labour involved, can be just as controllable as gas or oil, also can be boiler cylinder combined in one unit, closed system or open system, some are even condensing boilers

Follow the pictures, it is said that one picture is worth a thousand words, I can do a translation later, but the object of the overheat valves, is that they will open in the event of a run away boiler or an over heat situation (power cut/pump failure), and allow cold water into the boiler to "draw" some of the boilers heat, 1 will open the cold water and at the same time open a branch to allow the excess water to run to a drain, caused by the incoming cold water, the other just opens a branch to drain off the boiling water to a drain, and (do I hear gasps of horror) a closed system, (which is normal where I am) instead of an open system

Instead of fitting a Dunsley neutraliser, make the system a closed system, with an extra circulator and a check valve, to the solid fuel boiler job done
