datalogger to handle indoor and outdoor inputs?

[semlin]

hi, i am looking for a datalogger of some kind that would track a number of indoor temperature inputs including some radiator/heating, plus outside temp and weather information.  ideally it would also log the operating time for some appliances (boiler, circulator pump)

i have a big old house with an old radiator heating system and i am very interested in figuring out what weather conditions in particular are driving my heating bills.

i have been looking around and not finding anything that would do both indoor and outdoor data.  any advice is appreciated

Wired or wireless?  What is your budget?

wired is fine.  the budget is low.

Dallas 1-wire.  www.aagelectronica.com for the wx stn and some sensors although you can roll your own sensors for very little.
