Is there a reliable way to heat a microwaveable hot water bottle without a microwave?

We got rid of our microwave and the only thing we struggle with is the "hot water bottles" that use a bead filling and heat up in the microwave. Any nifty solutions? Doesn't feel like sticking them in the oven is a great idea.
