using black color sheet to wrap the beaker, then put under the sun.
u can use aluminum sheet, or mirror to reflect the sun light to shine on the beaker should help increasing the rate.
but if only not aloowed using fire, u can use electrical heater
btw, microwave is not recommended, especially pure water

唔用火燒,又要加到熱,緊係要用微波爐.
