There's no cold water storage. There's an unvented hot cylinder holding
maybe 25 gallons of water in the same cupboard as the boiler. If that
burst, most of the water would probably seep through the floor into the
flat below rather than doing much damage to our flat. [I'm guessing that
that would be covered by the Public Liability part of my insurance
policy even if water damage to my flat was excluded]

There's also the water in the (sealed) CH system - 8 radiators, I think
- none of them massive.

2 I presume the boiler has a latching over-temp cut-out and is a sealed
system, such that if there was any water loss, the boiler wouldn't fire
up from reduced pressure? So inherently a safe system, or as safe as can
be.


I think there's a latching over-temp trip - not 100% sure whether it's
active [ISTR that it can be bridged when the boiler is used with a
gravity HW circuit (which mine isn't)]. I presume that the boiler won't
fire if the pressure is too low - but again, I'm *not absolutely sure.

For one year I might be tempted to leave the stat at 13degsC just to see
how much gas is actually used, and keep a log. Another alternative is to
find another insurer, but the cost of water damage to your flat, and to
ones below would be not inconsiderable, so I don't blame them for making
such stipulations.


I doubt whether changing insurers would help. When we bought the flat
two years ago, we looked at insurers and this one had by far the best
cover and the least exclusions when the property is unoccupied - it's
just a pity that they are catching up with the rest. I would really like
to find a way of logging the temperatures for a while to see what
happens inside with no heating when it's freezing outside. Leaving the
heating on would scupper that - but if I don't, I risk invalidating the
insurance.


Maybe its time to assess the no insurance option?
