4What you need for installationComponents included in your Warmup PVC kit :• Warmup PVC Mat• Installation ManualAdditional components needed as part of your Warmupheating installation:• A Warmup® Thermostat with floor sensor.NOTE: Only Warmup® Thermostats should be used.• 30mA Residual Current Device (RCD), required as part ofall installations• Digital Multi-meter required for testing the resistance ofthe mat and floor sensor• Electrical housing, back boxes and junction boxes(Back box for the thermostat must be at least 35mmdeep)• Electrical trunking/conduit for housing the power leads• Duct Tape (to secure the floor sensor and loose wires)• Scissors for cutting the fibreglass mesh• Gloves• Warmup® Insulation BoardsIf the Warmup® underfloor heating mat is to be usedas a primary source of heating you will need to ensurethat you have adequate thermal insulation. A heat losscalculation MUST be carried out to determine whether ornot the heaters will provide enough heat for your room.Floor CoveringsThis installation manual gives instruction for installation of the Warmup underfloor heating mat under ceramic, quarry or naturalstone tiles. The maximum thermal resistance of the floor must not exceed 0.15 [m²K / W].Other Floor CoveringsIt is possible to install the heating element under floor finishes such as wood or vinyl by applying a self levelling compoundover the heating mat .You must ensure that all heating cables are completely covered with a minimum of 10mm self levellingcompound. It is important that the levelling compound is suitable for use with underfloor heating.Note: Delicate floor finishes such as wood or vinyl have a maximum floor surface temperature of 27°C. This temperature mustNOT be exceeded.Please contact Warmup for further advice if you wish to install the underfloor heating mat under any floor finishes other thanceramic, quarry or natural stone tiles.As with all electrical projects all mains electrical connections must beundertaken by a certified electrician. All work must conform to currentIEE Wiring Regulations. The Underfloor heating must be controlled viaa floor sensor thermostat at all times.Installing a Residual Current Device (RCD)The Heating Mats must be wired via an 30mA RCD. You must installa dedicated RCD if one is not already present. You may wish to use afused spur/RCD. No more than 4.8kW of heating may be connected toa single 30mA RCD.NOTE: It is possible to run the heater from an existing circuit. Consulta certified electrician to determine whether or not the circuit canhandle the load and if it is RCD protected.Installing Electrical Boxes and TrunkingYou will require a deep (35-40mm) back box for the thermostat. If youare installing more than two heaters, a junction box will be required.The wiring from the heater to the thermostat should be protected byconduit or plastic trunking.Connecting the ThermostatThe thermostat must be connected to the mains electrical supply viaa double pole isolator fused spur or RCD that has a contact separationin all poles providing full disconnection under over-voltage categoryIII conditions . The thermostat should be installed within the room to be heated. In most bathroom installations the thermostatcannot be located within the bathroom itself as the thermostat is IP20 rated and must be located outside of Zone 2. In suchcases the thermostat must be fitted to the outside of an internal wall of the bathroom, as close to the under floor installation aspossible. Once the electrical connections have been made and the system has been tested, the electrician must complete thecontrol card at the back of this installation manual. As per BS7671:2008 this information must be displayed at or near to theconsumer unit.Safety - electrical considerationsPower supply viafused spur /RCD.WarmupThermostatWarmupheating matFloor SensorPower Lead(coldtail)NOTE:Always run the powersupply cable and floorsensor cable inseparate conduit /trunking |
