Frequently Asked Questions of the heating mats for floor heating.
1. How much does the heating mat cost to run?
Consider an average room size of 10m 2
. The heated area is approximately 80%, or 8m 2 .
In the case of the 150W mats, when the heater is ON, the hourly consumption is 150W times 8m 2 , or 1200 Watts per hour.
properly insulated room, controlled by the recommended energy efficient
thermostats, will operate at a duty cycle of 20% to 25% (meaning 20% to
25% of the time the heater will be ON, and the rest of the time OFF).
In this circumstance the average electricity consumption for heating the room will be 240 - 300 Watts per hour.
The actual hourly cost depends on your local electricity rates.
2. Should I use insulation when installa the heating mat?
strongly advise to the use of insulation when installing the electric
underfloor heating system. By using insulation you can reduce warm-up
time of the floor from over an hour to only a few minutes. This will
provide you with a greater level of comfort and result in reduction of
3. Is it safe to use the heating mat in Wet areas?
Yes, the cables are earthed.
4. How easy is the heating mat to install?
The cable electric underfloor heating mats are extremely easy to install.
tiles, the installer simply lays the cable electric underfloor heating
mat directly between the sub floor/insulation and tiles. The same
flexible tile adhesive used for fixing the tiles is used for bonding the
Insomax insulation onto the subfloor.
laminate/ engineered wooden floors/ vinyl/carpet, the installer lays
the heating mats on the appropriate insulation as normal. A layer of
latex based self leveling compound (8-10mm) is then laid on top of the
cable heating mat. Once dry, the wooden flooring/ vinyl/ carpet can be
laying of the insulation and mats can be done easily by any consumer.
Due to the web like mesh, in most cases a primer will also not be
required- only a little amount of duck tape is needed to fix the mats
A qualified electrician must complete the connection between the heating mats and the electrical circuit.
5. How do I know which size mat to order?
the available exposed floor space in your room. It is advised that you
purchase a system which allows 80-90% coverage. For example, if your
room measures 15m 2 , you would purchase the 12.7m 2 Mat.
If a room is of an awkward shape with many fixtures in the centre of
the room, it is advised that you purchase a system that allows
approximately 80% coverage.
6. What if my room is larger than your largest available mat?
mats can be connected in parallel to a junction box. Please remember
that the thermostats allow a maximum of 15 amps, therefore the maximum
on one circuit is approximately 23m2. If the amperage in one room
exceeds 15 amps, then either a contactor will need to be installed by
your electrician or another thermostat will need to be purchased.
7. Can I cut the mats?
You can cut the mesh but not the heating cable.
8. What is the thickness of the cable?
The cable is 4mm thick.
9. Can I lay the mats under heavy objects/ fixtures?
- the mats can only be located in the available free space. There must
be some form of air gap between any furniture and the floor, so the heat
10. Does it provide a primary heat source?
most cases in a new build / well insulated property, the system can
provide primary heating. In cases where homes have single glazing,
vaulted ceilings, poor insulation levels or less than 80-90% cable
heating mat coverage, the system may need a source of back up.
11. What if my mat is a little too big for the room?
ordered mats can happen, in circumstances where the mat is a little too
big you can remove the mesh and lay the cables closer together. Please
note the smallest gap between cables is 5cm. Be aware that in doing this
you will find this area with the cables laid closer will be slightly
warmer compared to the rest of the area.
12. How safe are the mats?
mats are manufactured and tested in full conformity with IEC
(International Electrotechnical Commission) Global Quality Standards.
The continuous foil-coated screening jacket ensures 100% guarantee of
electrical safety and absence if electromagnetic radiation.
13. What is the warranty of this system?
The heating mats come with a 12 year manufacturers warranty 25 years
