Dear Ellen
I was wondering about chocolate fountains. We would like to have one or two or possibly three. I thought it might be nice to have an array of chocolates - dark, milk, white, possibly caramel. So, I was thinking it may be better to buy a few small ones rather then renting a large one. We will have about 150 guests. How much chocololate would I need?

As I wrote Jenny, while I am not opposed to food as entertainment, I have a prejudice about chocolate fountains at large events such as wedding receptions. ALL of them splash chocolate, they also drip and splatter, bad for dressy clothes. Cheap ones jam and are hard to clean up. People stick their fingers in, intentionally or unintentionally, or "double dip" their items. I think a good chocolate fondue in a chafing dish allows for much better quality chocolate and is safer to boot, especially if there are kids in the party. All the usual fountain sauces are tastier with dessert fondue pots, crockpots or chafing dishes... Rent a punch fountain instead! Make dipped strawberries, so they will taste like chocolate dipped strawberries/dipped fruits and be CLEAN. Platters of these would be a lot prettier than the fountain.
That said, one simple way to have a chocolate fountain for an event is to hire a person to bring, run and cater the fountain. You MUST have a continuous attendant for a chocolate fountain.
In the fountain, the chocolate is heated in the basin and then carried to the top of the fountain via a rotating internal shaft or "auger". So any fruit or other "dipper" dropped into the chocolate basin can cause an astonishing disaster. The person attending the fountain must IMMEDIATELY turn off/ unplug the fountain from the electrical outlet, retrieve the sinking piece of fruit or cake with a perforated/ slotted spoon to prevent it from plugging the fountain pump, then plug the fountain back in.
The usual charge for catering this (2006) is around $5.00 per person including fountain, attendant, chocolate, and dippers, with about a $150 minimum. It really does take one whole person's worth of time to manage it. Instructions will be included with the chocolate fountain on operating, dismantling and cleaning. If you rent one yourself to operate, you are responsible for cleaning the chocolate fountain after use before it is returned, and it is a painstaking, rather finicky job.
If you are considering buying a fountain, you MUST do a test run as long as the wedding. Part of the problem is successfully maintaining the dessert for the whole service. Again, it will take one person's attention almost continuously for the entire event. With chocolate fountains, it's vital that temperature control is precise, that the pump is silent and silky smooth, that the flow tree is plastic or stainless steel and not chrome (the chrome will flake off), and that the chocolate is of the best quality. "Sephra" is a reliable home brand.
Chocolate fountains are inside events. Remember that the chocolate has such an aroma that it will attract gnats and other little flying creatures. In addition, wind can blow chocolate all over your guests! Maintaining a constant warm temperature of chocolate is critical for continued smooth operation of the chocolate fountain, so outdoor weather can interfere with operation.
Supply plenty of disposable plates and napkins at the serving table. Use decorations that will not be harmed by spattering, dripping chocolates. Also, place a small garbage can near the fountain so your guests can easily discard their disposables. A patterned or dark colored tablecloth for the base of the fountain will help hide any chocolate drips.
If possible, set up the fountain on its own round table just large enough to reach across easily. The fountain is placed on a table that is sturdy enough to hold up to 85 pounds (40 kilograms) of weight and is close to a power socket.
Make sure the fountain tiers are correctly assembled with the curves up. They do not catch or pool the chocolate like a bowl; it runs off.
Plug the fountain directly into a wall outlet on a 20 amp circuit. It needs its own circuit; it CANNOT be used on the same circuit as percolators, microwaves, or other appliances. TAPE DOWN THE CORD TO THE FLOOR with heavy duty duct tape. The use of an extension cord is not recommended. If you must use an extension cord, please use a heavy-duty (at least 12 gauge) extension cord. If one must be used, refer to the national and local electrical codes. Do NOT use an adapter to get around grounding requirements.
Select the correct size of fountain. A home fountain is OK for up to 25 people, while the largest ones, nearly 4 feet tall, hold 20 pounds of chocolate and serve 200 to 250 persons.
THE UNIT MUST BE LEVEL TO OPERATE PROPERLY. Level the fountain: On most commercial fountains, the feet on the fountain are adjustable to allow you to level the fountain for consistent flow. Uneven sheeting of chocolate over the fountain tiers is usually the result of the chocolate fountain not standing level or of chocolate fondue is too thick and needs additional oil or cocoa butter added. A loud ”knocking” noise when the chocolate is running in the machine shows the machine is not level.
Never cover the vent holes that are located on the base unit directly under the bowl that holds the chocolate. Blocking these holes with linens, flowers or other decorations, will cause the mortor to overheat. The fountain should sit at least 1⁄4”from the surface on which it sits to allow sufficient airflow to enter the base and cool the motor.
Plug in. There is usually an on/off switch, a heat control switch for melting the chocolate and a separate switch for turning on and off the "fountain" part, called the auger. Set the temperature control for 250° ONLY if you prepare to melt your chocolate in the bowl itself. Chocolate chips or callets can be added directly to the pan in the fountain base and heated until melted. After your chocolate is melted, reduce heat to 150°.
When you first turn the auger on, as the chocolate reaches the top tier, turn the Chocolate Fountain off! Leave for ONLY one minute. This will get rid of any air bubbles on the auger.
DO NOT start the auger before the melted chocolate is ready in the bowl.. The auger motor generates heat and is designed for approximately 2 to 3 hours of use. Operating the fountain for a substantially longer period or operating the fountain with the auger running and the heat on at a higher setting could cause the motor to overheat. If the auger is turned off for more than a few minutes, the chocolate in the auger tube will harden. The auger tube will need to be cleaned out before the auger can be restarted. Forcing the auger to spin with the hardened chocolate in the auger tube will cause damage to the motor. If the motor is strained, the reset breaker will turn off the motor. Once the auger tube is cleaned, the motor can be restarted by pressing the reset button that is usually under the on/off switch.
You need 5 to 20 pounds of melted chocolate in place before starting the fountain, depending on the size of the fountain. You CAN melt the chocolate directly in the bowl, but it takes over an hour, so you have to start about 2 hours before you want to use the fountain. MICROWAVING or DOUBLE BOILER PREHEATING IS RECOMMENDED.
Add chocolate carefully. Beginning to melt chocolate you should stir the chocolate frequently, and you may have to melt what the basin can easily hold, and then briefly pump it up into the central cylinder to create enough room to add and melt more chocolate in the basin to complete the proper amount of chocolate needed for smooth even curtains of cascading chocolate.
MICROWAVING THE CHOCOLATE Pre-melting your chocolate or sauce recipe in a microwaveable zip-lock bag speeds the maintenance of the fountain. The chocolate MUST be placed in the microwave in the bag with the proper amount of oil added (a good estimate is 1/2 cup of vegetable oil per 5 pounds of high quality chocolate) on medium power for 3 minutes. Then the chocolate should be stirred by smashing the bag around- hold in oven gloves, it will be hot- or with a rubber scraper and put back in the microwave. Microwave again on low power for an additional one to three minutes. Carefully pour the melted chocolate into the preheated fountain, preheated 3-5 minutes at 100 .
Any blackening of the chocolate hints that it is burnt, if this occurs, discard it. It will spoil the entire batch.
DOUBLE BOILER METHOD: For 20 pounds of chocolate, you will need a heat resistant plastic, metal, or stainless container with similar dimensions to 30x12x12, ALSO a metal container with slightly larger dimensions for the hot water bath.
Additional melted chocolate can be added to a chocolate fountain while it is in use. Also, it is necessary to turn machine off and on for a minute every 20-30 minutes to re-prime the pump, to remove air bubbles and keep the flow consistent.
If the chocolate starts to harden once the fountain is in operation, turn the heat dial to 180 for several minutes, and add a little bit of vegetable oil. NEVER turn the dial to high heat when using chocolate, as the machine will overheat.
You want about 8 pieces of various dippers per person for a full dessert, or about 5 pieces for a reception.
The sauce/chocolate depends on the fountain, but allow for at least 1/4 cup per person. As a general rule, 20 pounds of chocolate will feed 200+ people. It must be high fat "couveture" chocolate (cocoa butter 33-60%). If using chocolate chips, you generally must add oil or cocoa butter.
Here is a recipe that can be used in a small fountain. You need to triple it for a 5 pound fountain.
