Can we buy 'UFH4U' products in the shops?
No. We only sell online and are the only supplier of these products. Selling our products direct to the public enables us to provide the best prices and services.
What flooring can the UFH4U' products be installed under?
Our products can be used under any floor surface. They may be used under:
Tiled floors (up to 200watts/sqm) by placing the mat or cable in the tile adhesive during installation.
Under wooden, carpet, linoleum, vinyl, or laminate by covering the heating mat or cable in 10mm of a flexible levelling compound first.
How can I get the best results from my system?
The best results can be achieved by taking in to account:
how well insulated the room is
the size of the room
the heat loss experience
whether you want the system to be a primary or secondary heating source
In addition, buying the most suitable product for the job. Further, efficiency can be achieved by sing 'UFH4U' insulation board - which will stop the loss of hot air and the will minimise the transfer of cold air up from the subfloor..
Where are your products made?
Our heating mats and cables are made in Germany.
Our Thermostats are made in Denmark.
How long will delivery take?
All orders placed before 3.00pm will be delivered the next business day by our couriers.
Do your products come with a guarantee?
Yes.
The guarantee on the Heating mats and the cables is 10 years as long as our installation instructions are complied with.
The guarantee on the Thermostats is 1 year.
Are your products different to your competitors?
Yes, most of our competitors use PTFE (Poly Tetra Fluro Ethylene) to insulate there cable. We use Teflon, which means our products are more expensive to manufacture, but it allows the cable to have a much higher burnout point, making our products much more reliable.
Our heating mats also have a fully adhesive backing g on them meaning you can obtain 100% contact and adhesion to the sub-floor. This assists when finishing the floor either with tile adhesive or levelling compound as there is no chance for the cable or mat to 'float' to the top.
Is your website secure?
Our site is hosted on a secure server in a secure data centre. We use 128 bit encryption for all of our order processing and credit card functions. Once we have processed your order, your credit card details are deleted from our system
Can you use more than one cable / matt from a single thermostat?
Yes. You can have up to 16 Amps (approx 3600 watts) connected to a single thermostat. If your room area requires a heating system which produces ore than 3,600watts then you will either need to use an additional thermostat or will need to have an electrical contactor installed
How do you join the heating mats or cables if you need more than one?
All the heating mats and cables are connected in Parallel (NOT in series). This means they each either connect in to the back of the thermostat or in to a 'junction box'. You can easily connect 2 mats / cables to the back of the thermostat - if you have more than 2, a junction box is required.
What is the maximum wattage per SQM allowed?
The highest wattage per SQM we would recommend is 200 watts per SQM and this should only be used beneath tiled floors.
Under carpet, wood or linoleum we would recommend a maximum of 160 watts per SQM.
What wattage would I require?
If you are looking at just taking the chill out of the floor, 100 watts per SQM is sufficient, if the room and sub floor are well insulated.
If you are heating a normal room 160 watts or greater is required, (choice will depend on floor finish).
If you are heating a conservatory or a bathroom (or other high heat loss area), we would suggest you use 200 watts per SQM (floor finish permitting).
We would also recommend the use 'UFH4U' insulation board to increase the efficiency of your system.
Will the heating system be able to heat the room sufficiently?
As long as you:
have selected a large enough product and
use the wattage as recommended above and
a floor and room which are suitably insulated
The system should be able to heat the room and act as the primary heating source.
If you have any doubts about the insulation, to achieve better results we recommend you use UFH4U' insulation board.
Do 'UFH4U' systems cost more than conventional heating to run?
Underfloor heating may be slightly more expensive than a conventional boiler / radiator system. However, the flexibility of having each room heated independently allows for greater control so these costs are negligible. Also by using insulation boards, the heating system is significantly more efficient. Whether using electrical under floor heating or any other electrical heating system, if operated at the same time of day they should cost the same to provide 1 KW of heat.
How safe is underfloor heating?
As long as our installation procedures are followed, our products are very safe. The cable is double insulated using Teflon, and has an earthed screen. In addition, the Thermostat we supply has a floor probe, which is buried, under the floor to monitor the temperature of the floor, if this gets to high, the thermostat will automatically turn the floor off.
Unlike many competitors, our systems use two conducting wires to minimise electrical magnetic radiation.
Can I install the 'UFH4U' heating system myself?
The heating system is very easy to install for the DIY enthusiast. We supply wiring diagrams and instructions for every aspect of the installation.
suitably qualified Electrician must be consulted about the provision of the electrical supply.
How hot does the floor get?
The floor will reach about 22 - 27 degrees Celsius depending on the room and floor temperature set. The thermostat supplied with your underfloor heating kit includes a floor probe. The floor probe is buried under the floor and stops the floor from getting too hot. The actual maximum temperate of the floor will depend on the:
wattage output,
insulation beneath the under floor heating and
Heat loss of the room.
Can I get help in working out what products I require?
Yes, if you send a room layout with all measurements shown, and the type of flooring you are using. We can provide a product list for you.
Please send your drawings to info@underfloorheating4u.co.uk or fax them to 0207 117 3084
A layout diagram can be downloaded from the support section of our website.
What happens if the floor gets wet?
'UFH4U' heating products all have waterproof terminators. They are also fully earthed in case of damage.
Can I use screws / nails to affix items to the floor on top of the heating system?
NO. Do NOT affix items to the floor using nails or screws as you may damage the heating cable. If the cable is damaged the earthed screening will protect you by tripping the RCD.
When planning your room and the installation of the heating system, do NOT put the heating system beneath areas where objects need a fixing e.g. Toilets, Kitchen units etc
Do you have to use a thermostat and floor probe?
Yes. You need a thermostat to protect the heating system, and to ensure the floor or room maintains your preferred temperature. Setting a maximum achievable floor temperature is essential with some floor finishes (maximum recommended by manufacturers under some finishes is 27 degree C) and you require the floor sensor to do this.
Is it dangerous to use electrical underfloor heating in a bathroom?
No. All our products are waterproof and must be installed with a RCD. When installing in wet rooms you will need o use a 'Damp Proof Membrane'.
Why do you need to use a primer on the sub floor?
This is normal procedure in preparation for tiling. The primer seals the floor, increases the tackiness of the floor and improves the adhesive qualities.
What is the output of the mats and cables?
The 3mm heating mats and cables are 15 watts/ linear metre
The 5mm In-Screed heating cables are 20 watts/ linear metre
Why do you have to use self-levelling compound or tile adhesive?
Levelling compound or tile adhesive must be used to cover the heating system to optimise its effectiveness and safety by equally distributing and transferring the heat.
Leveling compound / tile adhesive must be of the flexible kind and must completely cover the yellow heating cable to allow them to transfer the heat to the floors surface evenly. If not completely covered, the cables could burn out.
What is the best type of levelling compound to use as is required when laying under laminate, wood, etc?
The use of levelling compound is required when the floor finfish is to be anything other than tiles. The most important thing about using a levelling compound is that it must be flexible.
