customer wants boiler in unheated storeroom

[Gasinspect]

unheated storeroom, with louvre doors open to outside due to ventilation system installed in same room
warned them about risk of freezing - boiler will only be used a couple of days a week.
i know it will have a frost-stat, but that would not protect if there was a power failure, RCD trip etc.
Insulation of pipework would have to be 35mm, but that leaves valves,, filter, de-aerator - difficult to insulate them.
What else can i say to discourage the idea?

Why can’t you put the filter and other stuff in the heated space just fit the boiler in the boiler room ?

Also most commercial set ups are like this

Just inform the customer of your concerns.
If they are advised about it prior to installation in writing / email, just go ahead with it.

You can't be held at fault for a power failure or RCD trip.
