This kit contains the underfloor heating mat, digital thermostat, floor probe,aluminium foil tape x1 & flexible conduit.


This kit should be used in conjunction with our LAMFOAM insulation. This is available as a seperate item in our EBAY shop under catergory `Underwood / Laminate Insulation`.



The RFLAM mat is installed in the same way as a normal Underfloor Heating mat. It is cut and flipped in an identical manner. This method of installation compared to other under laminate systems is far superior. For example, an alternative system would be the carbon film method. This carbon film does not come in a rolled mat format and only in certain sizes. Multiple units are required to cover the entire area, plus each unit requires individually wiring to a central point. A time consuming and outdated method.

The RFLAM mat system we are offering is of a dual conductor core, again the same as standard underfloor heating mats. This means that there is only one cable to terminate.

The RFLAM system does not require fixing to the sub-floor insulation. The only fixings to the foil mat that are required are thin strips of aluminium foil (supplied with mat) between the runs of heating mat. The foil mat should be installed on top of our insulation which is available in our shop at a very competitive price.

The foil mats can be shaped shaped and are available as single mat sizes up to 10mt². Mats can easily be combined to heat larger areas.

The foil mats are also the safest product on market for use with wooden floors. They can be safely installed under a wooden floor in both dry and wet areas without the need for additional earth grids. The mats are fully earth protected.

Standards:       Meets all test requirements of IEC 60335 and is compliant with all new 17th Edition IEE REgulations.

Safety:            Proper earthing facility is provided for safety. Conforms to the product safety requirements as per   the latest EU Directives.

Approvals:       Conforms to the requirements of CE marking.

Installation Instructions:

RFLAM Underlaminate Foil Heating Mat System

 

The RFLAM underlaminate foil heating mat system is the ultra thin underfloor heating system from Radiant Floors primarily for use under laminate, engineered woods, and other floating floors. The following instructions should be read carefully before you begin your installation.

 

Please read these instructions and complete your Guarantee and return it to Radiant Floors after installation.

 

RFLAM systems are installed directly under laminate or engineered wooden floors, on top of the underlay. The LAMFOAM underlay must be applied to the floor before the underfloor heating. The underlay (floor insulation) shall be a 6mm layer of cross linked closed cell polyethylene, designed specifically for underfloor heating.

 

Radiant Floors Part Number: RF-CCPE6.

 

LAMFOAM is fixed to the floor with a flexible latex based adhesive.

 

Electrical Requirements

 

It is recommended the installation is carried out in accordance with local electrical regulations and the wiring of the system to the mains electrical supply is performed by a qualified electrician. Wiring and circuit protection to be compliant with BS7671 - 2008

 

The heating system is designed for operation at 230V 50Hz.

All installations require a 30mA RCD (residual current device) for safe operation.

Make sure the total current (amps) of your RFLAM system and other appliances connected to the circuit do not exceed the current capacity of the circuit. Normal ring main circuits are rated at 13A and the electrical feed can be taken from a 30mA RCD via a 13A fused spur.

 

The UFHSTAT thermostat has a 16A maximum rating. When the total load of your RFLAM system exceeds 3360 watts (24m² system) use a contactor to switch the electrical load, or alternatively split the heating into more than one heating zone each operated by its own thermostat  – always consult your electrician.

In bathrooms the thermostat control should be mounted outside the bathroom.

 

THE HEATING CABLE MUST NEVER BE CUT

 

To facilitate installation the cold lead wire can be cut to suit.

 

FLOOR PREPARATION

 

Wooden Subfloors – timber floorboards and chipboard. Make sure any loose boards are firmly fixed and reinforce the floor if necessary to prevent any movement in the floor.

The floor should be level.

 

Reinforcement can be applied to the floor by covering the complete floor with 18mm WBP plywood (weather & boilproof plywood).

 

Concrete Subfloors – Before proceeding repair any imperfections in the floor and level the floor with approved building materials.

 

Wooden & Concrete Subfloors -  Clean the floor surface so that it is free from dust, dirt, grease etc.

 

Prime floors with a water based PVA adhesive primer to improve bonding between the LAMFOAM insulation (Part Number RF-CCPE6) and the base floor.

 

Most tile or hardware outlets will supply this item and you will be able to purchase the exact specification and quantity required for the floor area involved.

.

First Step

 

Plan the installation.

 

Draw a general view of the room and mark the area which will be covered with heating elements showing the placement of the mats, thermostat, floor sensor and any junction boxes. Avoid heating under units and sanitary ware as this can cause heat blockage and it is unnecessary to heat these areas anyway.

Plan to use the larger RFLAM mats as much as possible to heat the required floor area.

 

Mark the position of the cold lead wire(s), at floor level. The cold lead joint is slightly thicker than the rest of the mat. Ensure the cold lead joints are embedded in the floor insulation / floor so that they are level with the rest of the mat.

 

When positioning the sensor it need only project into the room by 500mm. Make sure the sensor is placed at the opposite end from the heating wire loop. The sensor and sensor cable must not touch or be crossed by the heating element.

 

The sensor must run centrally (in the middle) between two runs of heating element so it is important to note where the elements will be positioned when installing the sensor. When installing a sensor tube make sure it is level with the heating element as shown below.

 

 

The tube can be cut to length to suit. Seal the end of the tube.

 

Floor Insulation

 

The underlay must be applied to the floor before the RFLAM underfloor heating. The underlay (floor insulation) shall be LAMFOAM, a 6mm layer of cross linked closed cell polyethylene.

 

LAMFOAM has been tested and chosen specifically for underfloor heating. It has excellent fire retardant properties, compression strength, thermal conductivity and working temperature range (-60 / +90ºC).

 

Radiant Floors Part Number: RF-CCPE6.

 

LAMFOAM is fixed to the floor (concrete or wooden) with a flexible latex based adhesive prior to fitting the RFLAM mats. Remember to prime the sub-floor prior to fixing LAMFOAM.

 

Testing

 

IMPORTANT: Before and during installation resistance continuity tests are necessary. Also, measure the insulation resistance value - the minimum reading should be 10Mohms regardless of the element length. All tests to be carried out in accordance with BS7671.

 

  • Test before installing, immediately after installing and before putting the heating into operation.

Consult a qualified electrician.

 

 

 

 

A digital multimeter is ideal for testing cable continuity and the resistance (ohms), as well as the resistance of the sensor cable.

 

Insulation resistance readings should also be carried out as required by BS7671.  

 

Mat Layout & Fixing

 

RFLAM mats must be fitted directly on top of the underlay (floor insulation), and directly under the laminate flooring – no screeds or additional materials are required.

 

Planning is important and when calculating the heated floor area leave a minimum unheated gap of 100mm around the room perimeter. The heated floor area must be free, avoid heating under kitchen cabinets, sanitary ware and appliances.

 

Make sure the RFLAM system can fit the floor area to be heated. It is better to have too little than too much over. Remember, NEVER cut the heating element. Cut only the element carrier (aluminium), and turn / flip the mat to meet your requirements as shown in the small illustrations below. Cut across the mat width centrally between two runs of heating element.

PLAIN WALL CUT

 

 

 

STRETCH TECHNIQUE

 

 

 

DOORWAYS

 

 

WARNING:   NEVER CUT THE HEATING ELEMENT

 

The position for the thermostat should be decided at the initial planning stage.

 

Check that the cold lead wire for the mat(s) will reach the connection – this is the connection with the junction box (depending on the number of mats) OR direct to the thermostat. When installing more than two mats the use of a junction box is recommended.

 

Arrange the mat on the floor, roll out and make the appropriate cuts. Make sure the mat is the correct way up. The exposed heating element loops MUST be on the underside of the mat when the mat is laid onto the insulation. The side marked “THIS SIDE UP” is facing upwards.

 

The RFLAM system is supplied complete with aluminium foil adhesive fixing tape. The mats are installed flat and fixed to the underlay with the foil fixing tape – see illustrations. When a mat has been cut and turned, or cut as in the stretch technique shown, the wire must be covered with aluminium foil fixing tape, so that you bridge the gap between sections of mat.

 

This is required to ensure the mat maintains its ground circuit throughout the mat.

 

Electrical cold leads must not cross each other or cross over the mats.

 

 

 

 

FIXING WITH ALUMINIUM FOIL ADHESIVE FIXING TAPE

 

Electrical Connections

When installing more than one mat mark the blue and brown leads coming from each mat with the same number for identification purposes. For example, MAT 1: mark both the blue & brown leads with 1, MAT 2: mark both the brown & blue leads with 2 etc.
