Am i being fussy bstard?

[fitz1]

was the system cleansed

has inhibitor been added

aluminium heat exchangers (central heating side) will corrode very quicky with treated water but stainless steel Primary heat exchangers will not.

Perhaps, but even if the primary Hex is SS, you still don't want softened water in the system because of it's corrosive effects on the system generally (so I'm told by DIA). On the other hand you want softened water feeding the DHW side. So the normal location of the filling loop isn't appropriate.

Fitz, you've forgotten -

Is the boiler installer Corgi registered?

Has the boiler installation been notified to Corgi?

 

[corgiman]

good point but what else on the system could suffer from treated water??

 

[festive]

Hey talking of the loop filler, shouldn't there be a sep cold feed near the boiler with a braided pipe and a non return valve on heater circuit. None of that there There CH feed to rads and return (in 22mm) have no extra connections

 

[corgiman]

what was total cost.cxi is stainless coil hx

thanks for that just check on glowworm website, so treated water to it aint a problem, in fact its adivisable to inhibit scale build up



nice looking boiler

You shouldn't put softened water into steel radiators.

forget my last chris doitall has already done it

Ask knowitall.

I'm off to look up the chemistry of water softening.....

 

[corgiman]

just asking why not steel rads but yes to steel heat exchangers??

No inhibitor in sight...ill take one more pic of all pipes.. one sec <gets out of bed>

 

[corgiman]

hold water softening

thats frighteningly close to the love child of water systems and softus

ARGGGGGGGGGGGGHHHH

the age of water soft


RUNNNNNNNNNNNN

 

[fitz1]

internal filling loop. look under boiler.

he means liquid inhibiter in the system m8 not an inline one

it should say on the benchmark cert the installer must have left with you

 

[ChrisR]

You don't want any "ions" in the boiler water. I may be wrong but I believe softeners leave both sodium and chloride ions in their output water. Chloride attacks stainless steels with a vengeance.

The boiler has an internal filling loop I think. They are slow and leak, but mean you don't have to have an external filling loop though one is suggested. You would need one to fill the system with unsoftened water of course.

Salt and steel is very corrosive, stainless steel is ok.

As we're pulling it to bits, what size and how long is the gas pipe

 

[festive]

OKay where's the filler loop? And Oops ive just noticed those two small pipes feeding the rad upstairs, i hope they're glued to that hep type piping.
