The Magma Radiator isn't available until you reach Rank 4 in the Mage Guild. There is no abstract requirement with how much stuff you have bought from the shop, simply be Rank 4 in the guild.
If you completed every Mage Guild quest in both LF1 and LF2 up to that point in the walkthrough, then you should have just reached Rank 4. (Pretty sure that was how it worked at least) So if you have any pending Mage Guild quests, try to complete them. Otherwise, there are two quests later in LF2 that can give you more Mage Guild points. You'll be able to do both of them before you'll need the Magma Radiator for anything.
