I have a bad track record when it comes to keeping tropical pitcher plants alive and its a shame because I think they are the most unique looking plants. About a year and a half ago I brought 2 nepenthes glabrata's and unfortunately they died after a few months.
Summer of last year was going to be different as I got a greenhouse but a combination of a fairly crap greenhouse heater, along with terrible winter temperatures seemed to kill off the tropical ones. So just for future reference, correct me if Im wrong but under no circumstances should the temperature drop to below 8-10'c in a greenhouse containing tropical pitcher plants?
I assume the following Nepenthes are dead?

You also seem to be standing them in water. Neps shouldn't really stand in water at the best of times, and certainly not in cold conditions. That, combined with looks like peat-based soil, may have assisted with rotting the roots.

With cheap heaters, use at least two, so if one fails the other one kicks in, also better to use a good quality thermostatic switch rather than rely on the cheap mechanical ones built into the heaters.
They may have frozen or were just too cold and too wet for too long.
