Hi Laura,
The 1000cc Hive heaters are used and loved by many fellow Geeks and are a good long-term investment. I believe Ellisons also make a similar style under their own brand name if you are looking for something less expensive, although the Hive starter packs do give excellent value for money as you get a selection of pre and post-waxing products, strips and spatulas for your cash.
As for hot wax, warm wax, gel and creme - it's not a silly question at all, it can get confusing with all the different names! Perhaps this will help:
Warm wax a.k.a. strip wax or soft wax, plus honey, gel or cream wax (depending on consistency and ingredients). Warm wax is heated in a pot or roller unit, then applied to the skin with a spatula, roller or disposable tube, and removed with paper or fabric strips. The 'gel' and 'creme' titles relate to the texture and ingredients.
Hot wax a.k.a. non-strip or stripless wax, hard wax, film wax, peelable wax, and Brazilian wax. Traditional hot wax is applied in a thick layer or built up over several layers, usually in a figure-of-eight pattern to ensure a good coating of the hairs. It is left to cool and harden on the skin and is then removed by hand. The wax "shrinkwraps" each hair as it dries, taking the hair with it when removed. Hot wax used to recycled by reheating and straining through a sieve, but nowadays it's thrown away after removal.
Newer hot waxes are cooler in temperature, go on much thinner and in one direction (no figure-of-eight needed), and stay flexible as they cool these new generation waxes are often called non-strip wax or hard wax to distinguish them from the traditional high-temperature hot waxes mentioned above. They are particularly effective at shifting short, coarse and stubborn hairs, but can take a bit of practice to use effectively and may extend your treatment time as they need to cool before removing. Many people like using them for sensitive areas such as the bikini area, underarms and facial waxing.
Sugar paste primarily a mixture of sugar, water and lemon juice, the paste comes in two varieties: strip sugar and hand sugar. Strip sugar is heated in a pot similar to warm wax, and is applied and removed with fabric strips in the same way. The temperature tends to be lower than with wax, and ingredients are totally natural and water soluble. Hand sugaring involves spreading a semi-solid ball of sugar paste over the skin, then quickly flicking in the opposite direction to remove the hair.
HTH's.
Good luck with your studies - there are many fantastic waxing Geeks on the site, and we're always happy to help where we can :hug:
