Hi. I have a morso squirrel multi fuel burner that heats 3 radiators and clorifier, it uses a circulation pump and my concern is what do I do uf the cir ulation pump should fail whilst the morso is lit.? As if this did happen the water in the back boiler would boil?. Any ideas.??

There are probably no answers that are satisfactory but I suppose you could riddle the fire down and then carefully spray the hot coals with water but that may scald you with steam and would make horrible mess with flying ashes. The safest although costly and potentially more unsightly is to re-plumb with in much larger pipes and in a manner that allows gravity circulation. If you do that the hotter the water gets the faster it circulates and so dumps more heat. You may also consider fitting another pump and switch so you have some redundancy. Most circulation pumps are centrifugal "pass through" types so the two could be placed in series. However you would have to regularly swap pumps so you know both are working. As long as the system has an open header tank and adequate supply and vent pipes you could shut the stove down and just let it boil. However it may well spit rusty water out of the top of the tank. I can not recommend shovelling the hot coals into the canal because if you dropped one a fire could easily ensue and it is easy to burn yourself.

It depends upon what the boiler is made from and also how high the fire is. If the fire is running away I suspect it could easily melt a copper or mild steel Boiler(I do not know what Moros use. I fear theer is no easy answer to this problem.
