There are some problems with this:
1. A 1 kW electric fire only uses a nominal kW of energy, it's more when you
first switch on, then it settles to approx 1 kW once it has warmed up.
2. +%5 of 900 W is only 945 W, so if your heater consumes energy on the high
side, you're going to be out of APC's spec. However, I'm not convinced that
the 5 % figure is that critical. After all, you only want a representative
load I would have thought. If APC's spec is critical though, then you might
have to think again.
You may have to resort to the light bulbs after all unless anyone has any
other bright ideas. (No pun intended.)
