Things to consider when fitting a ceiling fan in a conservatory
Conservatories make a great addition to many houses. It’s room that stays warm in Winter but in Summer it can get very hot. The addition of a ceiling fan can make a glass room usable all year round. However you need to make sure you follow a few guidelines to get the most appropriate ceiling fan for your conservatory.
Consider the size of ceiling fan. The heat build-up in a conservatory can be extreme so we always recommend fitting the largest ceiling fan that you can. Generally a smaller ceiling fan (36″/92cm span) is not adequate to deal with the heat in all but the smallest conservatories. At Fantasia we recommend fitting a minimum of a 42″/107cm span ceiling fan and larger if you can.
Think about the length of drop rod required. In almost all cases a conservatory ceiling fan will need to be drop mount. By this we mean a ceiling fan that has a drop rod installed rather than a flush mounted fan. Generally an 18″/46cm length rod is advisable. Fantasia rods can be cut down to size if required.
Think about clearances. A Ceiling Fan will only be effective if the tips of the blades are clear of any obstacle. When you a measuring for a ceiling fan you will need to add 20cm to each end of the span (and also all around the blade) to allow proper air movement. Some conservatories have structural tie bars. These and also the slope of the pitched roof need to be taken into account when allowing space for the fan blades to spin.
Fit your fan to any old bit of decorative plastic you feel like. Yes, we have seen it done! Ceiling Fans aren’t that heavy but the guideline is that the fixing should be able to take 4 times the weight of the fan. Most ceiling fans weight less than 10kg so the fixing will need to be able to support 40kg. In most cases it is worth talking to the conservatory manufacturer or installed to decide in the best place to fit the fan. If it is a UPVC conservatory then make sure the fixing screws are long enough the penetrate the plastic and also the structural aluminium underneath. To help with fixing a ceiling fan to a conservatory ridge Fantasia produce a Big Strip Fastener. This provides extra fixing holes and can be very useful.
Use the fixing screws that some with the ceiling fan. All Fantasia ceiling fans are supplied with wood screws to fit the fixing bracket. It is not advisable to use these to fit a conservatory ceiling fan. Use self tapping screws instead.
Obviously we would prefer you to purchase a Fantasia Ceiling Fan but actually these guidelines will apply to most ceiling fans fitted in a conservatory.

I’m afraid I have to preface this blog entry with the usual disclaimer that before starting any electrical work you should ensure you have ‘all pole disconnection’ from the unit you are working on. I should also say that if you are unsure about anything to do with wiring and electrical work in general then consult a qualified electrician.
I’m not saying this because connecting a ceiling fan to a lighting circuit is difficult, it’s not, it’s just that when someone does something stupid then they tend to want to blame someone else. All I’m saying is that if you are that sort of person then don’t use this guide. Fantasia Ceiling Fans won’t be responsible for any loss, damage or anything else resulting from this blog entry.
Right, now down to the questions you may have :
Q. Does a Fantasia Ceiling Fan use the standard lighting circuit?
Q. Do I need to run the fan from a fused spur?
A. That would be recommended but not essential
Q. Can I control the fan and light separately?
A. This is a question that always makes me laugh. Do you really think that you could only have the light on when the fan is on and vice versa? Do you think that would be a good product? No it wouldn’t and therefore all Fantasia Fans have independently controllable fan and light functions.
Q. Can I control the fan from the permanent live and the light from the switched live
A. Yes, this is an option and some people do it but we prefer to only use the switched live for isolation purposes.
Q. Are fan lights dimmable
A. If the fan comes with a remote control or wall control then the answer is yes. If the fan light just has a pull cord then the light will just have on/off functionality.

Another ceiling fan question answered.Q. I know that you recommend that ceiling fans are fitted to a ceiling joist. I have just had a new conservatory fitted and I now want to install my Fantasia Fan. The ridge section of my conservatory is Aluminum covered with white plastic. What’s the best way to fit a ceiling fan? A. A lot of Fantasia Fans are purchased for fitting in a conservatory as they are ideal for that environment. However, a conservatory ridge section is a complicated thing (see slideshow below). In many cases you will need more than 2 fixings to make it secure. For this reason Fantasia has developed the Big Strip Fastener (see slideshow below) in order to allow for many more fixing with self tapping screws. If you are having a new conservatory fitted than ask you’re installer if you need a Big Strip Fastener.

Here’s an example of the one of the questions we get asked about fitting ceiling fans.
Conservatories often have tie bars included to keep the structure square. They can get in the way though when fitting ceiling fans. There are 2 things to remember when dealing with tie bars – Support & Ventilation . Firstly don’t ever attempt to attach a ceiling fan to a tie bar directly (yes, we have seen it attempted!). Tie bars are not designed to take any vertical load at all. Secondly, make sure that you ceiling fan has good clearance from the tie bars. The blade tips must be at least 8 inches (24cm) from the tie bar or any other part of the conservatory. If the blade tips are too close to the tie bars then you will feel no downdraft from the fan at all.
