Domestic or Commercial?

[Davinder]

I've got this job in an office block, where I handle there maintenace requirements and they've asked me if I can service there boiler.

Now there's two Remeha Quinta 45 linked together via a low loss header. My question is, as there two 45Kw boilers linked together do i count it as a 90Kw instalation and need someone with a commercial ticket, or as each individual boiler is only 45Kw a domestic ticket will be ok?

Would prefer to run it in steel than use denso....

Steel looks a lot more professional 1" barrel bent and welded non of this threading nonsense!

Remember i'm domestic haha
sod welding

I really need more experience welding as it's a lovely skill but that's what pipe fitters are for!

No but a plant room with two Andrews water heaters in does! You can legally install a domestic boiler on a commercial gas carcass with a volume in excess of a zillion litres if there is a test point and isolation point down stream of your equipment and your working in a permitted location. I did a boiler swap in a laundry no to long ago. I called technical as I was sure I shouldn't but they said asking as from test point to boiler is within my scope jog on!

Keston c50 was branded as light commercial but lots and lots if them in houses on u16 with 28mm tube !

i phoned gas safe last year regarding working off an AECV with a test nipple etc .

they said its fine however i couldnt turn the AECV on to gas up appliance as it would then put me past my domestic licence due to volume of gas .So i could install ,and do a TT but then i would have to turn appliance off and get a commercial guy in to turn on AECV .

Not that it matters now as im commercial
