Ceiling Fan comparison Chart

This is a follow through article after research on the general considerations in choosing a ceiling fan. If you have not read it, the link is here (coming soon)

Unique to our needs, we have summarized our requirements as follows:
1. Size of fan in accordance to the room size.
2. Ceiling height about 2.3m. We cannot afford a low hanging fan.
3. High Aesthetics is important to satisfy my better half's requirement
4. Light kit is a must!

Guided by the above requirements we visited 7 showrooms over 2 weekends and shortlisted 5 options as follows:
1. Crestar Rainlite
2. Crestar Skylite
3. Fanco FF707
4. Acron Ventieulator 218
5. Vento Mela distributed by Amasco

You can probably guess our final choice from the photos below. For the benefit of the readers, we still want to share the selection process. Our 2 weeks of fact finding and comparison has been summarized into the following comparison chart.
Note that the Fanco FF707 specs are from our living room ceiling fan purchased in 2009. Read the review here (coming soon!)
Comparison Discussions with the sellers:

1. Crestar Fans offer great value with their Aluminium cased motors. Aluminium releases heat well and does not rust. One seller explained that Crestar used German Technology, built in Taiwan. I loved their functional appeal. Unfortunately, its aesthetics did not appeal to my better half.

2. Fanco has a competitive price (at least in 2009 when we bought it)  This is a good choice for something decent looking but on a tight budget. The have very similar design to Amasco. Read our review on our Fanco FF707 here (coming soon)

3. Although we have never heard of the Acorn brand, but we asked extensively about it as we found the unit on display elegant. The motor body is largely hidden by the light kit.  The seller explained that Taiwan makes the "best" ceiling fans. He explained that several ceiling fan marketing companies that have their products OEMed by the same few Taiwanese factory. Thus they have the same quality despite the different brands. Acorn is one of them.

4. Vento's Mela really caught our hearts. See here to understand why. It remained our 1st choice until the last minute when we realized the price tag was sufficient to purchase 3 standard ceiling fans. There was also an unfounded doubt on the ease of maintenance and lifespan of the  blade rotation bearings.

5. KDK is a household brand I grew up with. However we did not consider KDK as they did not provide much options with lighting kits. Perhaps another reason is our choice of showrooms did not promote KDK aggressively.


The most balanced choice was the Acorn.

From our research, generally the key recommended considerations are the room size, ceiling height and lighting kits.


1.  Room size: 44” or 54” sized fans?

Firstly, the measurement of the fan sized we were told is NOT measured from the diameter of blade tip spinning path. It was rather complicated and we gave up trying to understand it. If anyone knows please let us know. As recommended by several sellers, for optimal performance:

For room size below 100 square feet 
(typical old HDB 4R common bedroom) - use size around 44”

For room size 100 to 200 square feet 
(typical old HDB 4R master bedroom) - use size around 50”

For room size 200 to 350 square feet 
(typical old HDB 4R living & dining room) - use at least 54”


2.   Ceiling Height

Standard HDB ceiling height are less than generous. Unless the ceiling fan is mounted above a non-walking path eg dining table or bed, the choices are pretty limited. For low ceilings there are a few low profile and flush mount fans available in the market. One of the smallest one we found is the KDK M11SU


3.   Light Kits

Some ceiling fans models come with light kits and most have optional add-on options. It is a good way to mount one more light in the room and saves the cost of an extra light point.

Why we had a ceiling fan in the Bed room.

Room ventilation generated by ceiling fans can make the ambiance feel cooler by a few degrees. This is something standing and wall fans are not designed to achieve.
When applied intelligently together with air-conditioning, it can help to save electricity consumption. This was how I convinced my wife the savings without doing a laboratory test:
When using the air con with ceiling fan, this 2 additional steps were applied:
1.   Set the thermostat on the aircon to 3 to 5 DegC above the preferred ambiance temperature. For example, if you are used to sleeping at 20DegC, set the aircon thermostat to 25DegC.
2.   Set the auto off-timer on the aircon to 3 hours before your wake up time. For example, if user sleeps at 10pm and wakes up at 6am. Set the aircon auto off-timer to 3am.

S$ 58 per month per room
Assumptions:

(A) Assume 0.1kM savings from thermostat temperature difference of 5DegC.
(B) Typical 1 air con blower from a system operating at 8,540BTU/hr = 2.5kW
(C) Typical ceiling fan power consumption = 60W to 90W (costing about S$300 to purchase)
(D) Estimated electrical consumption = Input (kW) X No. of hours used X No. of days per month X Current Utility Rate

The choice seems clear! Conservatively, even if the real difference is only half of the calculated, the electrical tariff savings will pay for the ceiling fans in 10 months! The only exception I can think of is if users cannot sleep in a “windy” environment due to arthritis.

Disclaimer: We are not trained electrical engineers. The above is a heartlander trying to make sense of the small things in life. Apply at your own risk! If there are any experts out there who can correct or verify this, please leave a kind comment.

Lighting Concept- Living Room

The approach to the lighting concept was to have a "functional lighting" and a "mood lighting".




Functional light 
1. Choice of white light for reading on the sofa
2. With a ceiling fan and no downlights or cove lights (see why here) we opted to choose a ceiling fan with built-in light to reduce the spinning shadow effect caused by the light located above the fan blades.

Mood Lights
1. Choice of yellow light
2. Can be used as a night light during the childrens' quiet time before bed.
3. Installed through wall mounted and ceiling mounted chandlers.


The cost savings of converting from down lights/cove lights to the above lighting concept can be found here.

Improved Toilet Layout- Cost of Renovation

There has been numerous inquiries about the cost of renovating the toilet.

However, there are a few assumptions before sharing this information:
1. Do bear in mind that this was priced in end 2009 and offered as part of a complete renovation package.
2. Excludes demolition works and installation of all other toilet accessories.
3. Toilet is approximately 4.8sqm in floor area

a. S$1700: To Supply and Lay ceramic floor tiles c/w water proofing (Material cost up to $3/ft2)
HDB renovation- toilet floor waterproofing
For your information:
water proofing needs to be done under the toilet floor tiles. The failure of this waterproofing is often the cause of a wet/ leaking toilet roof between neighbours on the upper and lower floor.

b. S$1500: To Supply and Lay glazed wall ceramic tiles including low wall @ 1 toilet (Material cost up to $3/ft2)

HDB Toilet- Wall tile near completion

c. S$920: To supply and install 1500mm wide vanity top c/w integrated Bowl
d. S$820: To supply and install 1500mm wide suspended cabinetary c/w mirror panel door (Material soild ply/Laminates)

Demolition

The renovation contract was finally signed with my Interior Designer (ID) and he had his contractors start work ASAP. The contract was accompanied by the agreed scope of work and time frame allowed for completion.

Should there be floor or wall hacking involved in the HDB renovation, the contractor whom is carrying out the works must be a HDB approved contractor. They will apply for the HDB permit on the owner's behalf over the period of renovation. Please take some time to look at the permit carefully. HDB will hold the owner liable for unauthorised works.

Make sure that all demolition works agreed in the contract are clearly mentioned in the HDB approved permit. To protect your own interest, it is a good idea to have an agreed layout drawing attached to the contract.

The other consequence in an unauthorised renovation will surface when you resell the flat. During the resale transaction, HDB has a right to insist the seller (which will be me) to "make good" to the original state. Future money, time and effort can be saved by due today's diligence.

Typically, HDB's work permit includes 3 specified weekdays for heavy hacking. the contractor will try to finish up all the hacking within these 3 days.

Dropping by to spot check on the works, not a pleasant part of the renovation to be monitoring. Gotta be careful not to trip. Remember to wear covered shoes.

I recall meeting an elderly neighbour in the lift who was staying at the unit directly below mine. She was complaining to me that she cannot take her afternoon naps due to the noise from the hacking. It is obvious why HDB limits disturbing works to 3 days.

Trying to start on a right foot into the neighbourhood, had to do some PR and talked to the adjacent neighbours and told them about the hacking should end in 2 day's time. :P
