Kev the gas

Evening all, I was called into help a local hotel for the blind yesterday.

In the plant room was a 70 kw condensing boiler which had been converted to a sealed system.

Sorry for the poor pics below taken on my phone but Im sure the knowledgeable chaps u r, will see the clever use of a spare flue elbow used as a diverter for the pressure relief valve ! Genius rather than the water hitting the floor, divert it further into the plant room !!



I was called in to repair a leak on the condense pump.

I then asked why the 300 ltr cyl was so noisy they said it always does it, then checked the 2 x 50 gallon water tanks in the loft. F..k me never seen anything like it, it was like a Turkish sauna, all 2 tanks were bubbling away ready to split.

New H/water zone valve fitted this morning, felt like a life saver this morning. :coolgleamA:

You get the same standard of idiots on commercial too, especially smaller things
 
That filling loop is illegal. Needs a pressurisation unit
 
is there a minimum size of system were it changes from filling loop to presurisation system?

45kw max on filling loop.
Water is 45kw> is cat 3. >46kw is cat 4. So u have to have pres unit

Great spot. Not doing commercial work I didn't realise what you were talking about but now I've learnt something.

Glad it doesn't apply to domestic cos I've fitted several boilers above 45kw.

Condensing boiler installed by local Gas Safe plumber in 2014, not combi. Failed a couple of weeks ago with flashing blue light which googling suggests means no gas, blocked flue or blocked condensate pipe. There is gas, the flue is clear, and the condensate pipe goes into the under-sink waste...
