Frequently Asked Questions
Q
Where do the wires come out on the mirror heater pad?
A
This varies from model to model. Please view the diagram at the bottom of the Mirror Sizes and Pricing page.
The wires exit the heater pad through a sealed connection block 30 by 30mm square and 5.5mm deep, 140mm
in from the edge of the centre of the shortest side. If the heater pad is smaller than 300mm at the longest dimension, then
the connector block
is in the middle of the heater pad. The one meter long power cable (called a
cold tail, as it doesn't get hot) is oval in cross section 5.5 by 3.0mm with Brown & Blue
coloured wires. If exact location of the wire/connection is critical please email or call for advice including details of the exact model you require.
Q
My mirror is in the shower cubical or above the bath (Zone 1). What else would I need with a SELV model (12V) MirrorMaster heater pad?
A
You will need a 12V transformer (located outside the immediate bathroom area) connected to your bathroom lighting circuit. Some bathrooms already have low voltage (12V) lighting systems installed, but if yours doesn't you can purchase a suitable transformer from us.
Q
I see your prices include VAT, can I avoid that?
A
Only if you can avoid it legally, which normally means that we will be shipping outside the E.U. We supply a VAT invoice that will allow you to claim back the VAT if you are VAT registered.
Q
Can I pay by cheque?
A
Yes, your MirrorMaster Heater pad will be dispatched as soon as the cheque clears. Make cheques payable to "Ceetek Limited".
Q
Can I cut down a larger pad to make it fit my mirror?
A
No, each pad is made and sealed; you cannot drill it or cut it. Please allow for fixing screws when ordering your mirror heater pad. However our Circular and Oval mirror heater pads are supplied in a square or rectangular shape. This allows the heater pad to be squarely placed on the back of a rectangular mirror. If the actual mirror is circular/oval then the excess material can be trimmed, so long as the heating element wires are left within 25mm of the edge of the heater pad.
Q
My mirror is much larger than your biggest heater pad, what do I do?
A
Wow...that's a big mirror. You can add multiple heater pads, as per the diagram found here Wiring and Installation. Note the heater pad normally clears an extra 1-3" (25 to 76mm) from the edge of the heater pad. How far depends on the thickness of the mirror, glass type, dew point of the air, the wall material the mirror is attached to and the normal mirror / wall temperature.
Q
Can the 12V wires on the MirrorMaster be connected to my existing 12V lighting system?
A
It depends on the capacity of the transformer. We have put the wattage of our heaters in the table found here Mirror sizes. For instance if you have an 20-70W transformer with a single 50W lamp, you could also support one R500x250SELV 18Watt mirrormaster demister.
Q
Can anyone install a MirrorMaster heater pad?
A
The EU law now states that nearly all electrical work in the home should be undertaken by an electrician.
Q
Can I buy MirrorMaster in the shops?
A
MirrorMaster is not normally available on the high street, but many quality plumbers merchants and bathroom shops stock our mirror heater pads.
Q
Who is Ceetek Electronics in relation to MirrorMaster?
A
Ceetek Limited is the top level company for Ceetek Electronics and MirrorMaster. The bank, Paypal and credit card facilities are all in the name of Ceetek. MirrorMaster is 100% owned by Ceetek Limited.
Q
I'm going to glue my mirror to the wall / tiles, will that affect the mirror heater pad?
A
The semi-smooth finish of MirrorMaster is designed to allow any normal mirror fixing method to be used, so gluing or using silicon adhesive is acceptable.
Q
I've had a foil type mirror heater before that didn't work properly. How can I be sure a Mirrormaster will work?
A
The foil type mirror heaters, normally 24V, only generate a very small amount of heat. This means that they have to be left on permanently, however this does not guarantee that enough heat will be made to keep you mirror clear of steam. Our 200 watts of heat per meter square (150/m2 on the SELV) allows us to keep your mirror clear of mist even under the most hostile of conditions.
Q
Either for budget or aesthetic reasons I only want to keep a small area clear of steam. I've heard this may crack the mirror, is that true?
A
Standard mirror glass will normally with stand a 30°C increase in part of the mirror without any cracking. Our Mirrormaster only applies enough energy to heat by 15°C. The Oval and Circular Mirrormasters are designed to take advantage of partial heating allowing this artistic "window" view on any shaped mirror. If you chose to partial heat a mirror ensure the Mirrormaster is installed towards to top of the mirror. This will prevent any mist water running down from an unheated part of the mirror running down through the steam-free area.
Q
The mirror manufacturer has added a foil to the back to our mirror and they says that we cannot fit a mirror demister. Will a Mirrormaster will still work?
A
Foil is added to the back of mirrors for two reasons. One to
help protect the mirror surface from corrosion and the other is to act as a
bonding agent to keep the glass together in the event of the mirror breaking.
The MirrorMaster can perform both these functions, as well as keep your mirror
from misting. The foil will act as a spreader / reflector for the heat and cause
the mirror to take slightly longer to get to temperature.
One concern we have is that we are no longer in contact with the mirror, so if
the foil glue is weak, then the mirror may delaminate from the foil. If you are
reliant on adhesive to keep your mirror in place, then you should seek
assurances from the mirror manufacturer concerning the strength of the foil to
mirror glue.
Q
I want to dim my 12V lights in my bathroom. If my Mirrormaster is being driven by the same transformer will it still have enough power to keep the mirror from misting or will it damage the Mirror pad?
A
Our advice is that you cannot damage our Mirrormaster by running it through a phase angle or resistive dimmer, however we may not have enough power to heat the mirror above dew point, so you may experience fogging.
How Does It Work?
MirrorMaster works by ensuring that the mirror is at least 10 to 15 degrees warmer than the ambient temperature of your bathroom.
Our 0.5mm thick mirror heater pad is simply bonded to the back of the mirror by removing the backing paper and gently smoothing it onto the rear of the mirror. The Mirrormaster is normally powered by a connection to your bathroom light circuit.
When the bathroom light is switched ON the mirror will warm up and keep clear while the bathroom is in use.
Mains powered MirrorMaster self-adhesive mirror heater demister (demista or Denmista are common spelling errors) pads are available in a selection of shapes and sizes to suit your requirements.
The most popular are the 12V SELV series that can be simply applied to the rear of your mirror and connected to your bathroom light via a small 12V transformer, like low voltage lighting (see diagram). These are used in Zone 1 and 2 semi-wet areas (see I.E.E. regulations 17th Edition).
