Hi. Where an L2 system requires detection in high risk rooms such as kitchens and boiler rooms, would a calorifier be considered a high fire risk too? As an example, in a commercial premises with guest sleeping accommodation, would detection be needed in a cupboard containing a direct electric hot water heater (located within a common area)? I'm assuming it would?

Thanks

That's up to the designer, usually in conjunction with the risk assessor, every element above that required for L3 is specific to the design intent for that building - some would cover it, others might not, but both could be correct!

 

Hi Anthony. Thanks for the reply. Would a directly heated electrical water tank usually be considered a significant fire hazard? - e.g. on par with a gas boiler or consumer unit?

Thanks!
