Heat lamps aren't as hazardous in a house as in a barn, IMO, because you are more likely to use them properly and see what's going on and have working smoke detectors and such. And a house is a less dusty and combustible-filled environment.
Make sure the heat lamp is suspended by two independant points, by SECURE material (chain or heavy gauge wire, securely attached at both ends) to FIRM RELIABLE attachment points (don't use decorative ceiling hooks of questionable security, don't hang from a bent nail, that sort of thing)
Make sure the heatlamp is not excessively close to combustibles (bedding, cardboard, plastic, even wood) and cannot be knocked to where it *is* too close. A 250w bulb should be 16-18"ish from any of those things; a lower wattage bulb can be closer if necessary.
And make sure the batteries in your smoke alarms are working (as a general thing, of course, not just for this
)
It'll be fine
Good luck, have fun,
Pat
