FlexHeat Universal Underfloor Heating Cable

A flexible simple to fit heating system designed to provide energy-efficient floor warming or a full heating system as desired. This electric underfloor heating cable is particularly suited to small or intricate areas where heating mats can be more complicated to install.

The system's output is varied by altering the spacing of the heating cable, allowing 200W/m to be installed in conservatories and similar high heat loss areas. An additional benefit of this system is that it can be used beneath virtually any floor covering if covered with a levelling compound and installed with an output of no more than 160W/m2.

  • When installed at 200W/m2 this system is suitable for providing a full room heating system, even in high heat loss areas such as conservatories
  • Perfect for floor warming or room heating in standard rooms when installed at 160W/m2
  • Alter the heat output to match your individual requirements - outputs from 80W/m2 to 230W/m2 are possible
  • The compact FlexHeat range is designed for installers to be able to keep a small range of sizes in stock which can be mixed and matched to provide coverage for nearly any room
  • When used with Heat Mat's intelligent thermostat timers this heating cable provides a more energy-efficient and cost-effective heating system than lower powered alternatives
  • Great value for money - can be installed on thermal insulation boards to provide a faster reacting and more economic heating system
  • Significantly quicker to install than some alternative systems as there is no need to cover the entire heating cable with tape due to its high strength outer insulation

FlexHeat Cable converts electricity into heat with almost 100% efficiency, so the running costs of a system depend largely on the room’s insulation and the target temperature.

The better insulated a room is, the less expensive it will be to operate the underfloor heating system, with the largest benefit being obtained in installing thermal insulation boards directly beneath the cable.

When installing FlexHeat Cable at an output of 150W/sqm onto a well-insulated floor, we would expect the underfloor heating system to operate on average for less than 40% of the time to provide a total heating system. With electricity costs of 10 pence per kilowatt hour, this would lead to running costs of around 0.6 pence per hour when the heating system is running.

Assumptions made for the above calculations:

  • The FlexHeat Cable has been installed at an output of 150W/sqm
  • The cable is installed on top of 10mm thermal insulation board, beneath standard ceramic tiles
  • 100% of the floor is covered with underfloor heating
  • The insulation in the property is up to the current Part L regulations
  • The price of electricity is 10p per kilowatt hour
  • The system is run via Heat Mat's Part L Compliant 4th Generation NGT thermostat, with the anticipatory setting enabled
  • The system is operating while the average ambient temperature is 10oC, and the system is heating the room on average for ten hours a day

UK Delivery:

Orders over £50 - FREE DELIVERY*

Orders under £50 - Delivery £4.95 including VAT

*A very small number of large heavy items may attract an additional pallet charge to certain areas. This charge is calculated based on the overall order value and the delivery postcode area. For example, large oil-filled heaters such as the 'Rointe Radiator Range' cannot be safely transported via standard courier services. Depending on your area, there will usually be a carriage paid order value threshold where FREE delivery can still be attained.

Overseas Customers:

Please feel free to contact us for a price if you would like delivery outside of the UK.

Same Day Despatch On In-Stock Items:

We despatch in-stock items on the same working day when they are ordered before 2PM GMT. You can always contact us after this time to see if it is still possible - we are keen to help where we can. If you need a timed delivery service (Before Noon, 10am, 9am and Saturdays etc) - then please contact us directly for a price.

"Fastlec- They really mean fast, press the enter key on your computer and the doorbell rings.

I have used Fastlec three times each time I have found them to be efficient fast and happy to give you information on their products."

If You Have A Deadline:

Out of stock items will show a 'usual' delivery time on the product page, we will notify you if they are likely to take any longer than this. If you have a deadline then please feel free to contact us by email, phone or fax - we can usually meet it!

Fast and Secure:

Most in-stock items are despatched via traceable and insured carriers on a next-day service.

Domestic Addresses: Our carriers deliver between 7.30am and 6.00pm. If you are not in when the carrier arrives, they will leave a card with instructions on how to arrange re-delivery or collection from your local depot.

Business Addresses: Our carrier will attempt delivery on a working day during normal business hours. If there is no-one to sign for the delivery, a card will be left and the parcel taken to the local depot for collection within one week.

Received Damaged:

Any items being returned as damaged in transit, requiring replacement or refund, should be notified to us, either verbally or in writing, within 24 hours of delivery and must be accompanied by clear photographs showing both the packaging - particularly any damage to the packaging - and also the damaged item(s). The correct paperwork can then be sent and these photographs will ensure that replacements or refunds can then be processed with a minimum of delay.

Storage Heater Deliveries:

Even when purchasing a single heater, it will be delivered on a pallet in an attempt to ensure no damage is caused during transit due to the weight of the unit and also the weight of the bricks to be fitted into the unit on installation. Multiple heaters may even mean multiple pallets. The nature and weight of these items mean a truck fitted with a tail lift is usually required and deliveries can, on occasion, be held up waiting for the availability of specialist transport although this is unusual. 

Today's couriers, due to stringent Health and Safety restrictions, who are employed to deliver your storage heater, are contracted to deliver to the external front of your property only and are not contracted to maneuver these heavy items into your house or to their final locations. The item will be delivered to the door of the outer building if access allows (low-level pump trucks are used to move the pallet, therefore, any steps on the way will make this difficult and will probably mean delivery to the bottom of the steps only).
It is your responsibility to ensure that you have adequate manpower (2 people recommended) to transport your new heater(s) and bricks from the delivery point to its final location without injury or damage to yourself, your new heater, or your property.

These considerations have been carefully designed to implement safe shipping and handling practices that will ensure safe and intact delivery of your heater and safe working practices for the delivery personnel.
