Wood floor requirements
Wood flooring with glueless locking can be floated over the top of the foil heating system. For effective heat transfer avoid wood flooring thicker than 18mm. Always check that the wood floor is suitable for use with underfloor heating.
If using an underlay make sure you choose one that is suitable for use with electric underfloor heating and with a low tog rating to allow heat to pass through.
Do not use the foil heating mats with glued locking systems or laminates that have an underpad or cushion material pre-attached to its underside. – The foil heater is only designed for use with floating floor types.
You can glue locking systems down if you use WDOC (Warmup Dual Overlay Concrete) over the heater and then glue the flooring to the WDOC.
Do not overlap heating mats, fold or wrinkle the foil heating mats. – This will result in failure of the heating system.
Do not install foil mats within approximately 50mm of any heat conductive building part, such as cold-water pipes.
Do not use this heater directly under any floor covering other than wood or laminate. -Only when used in conjunction with the dual overlay system.
Do not install the heating mats direct contact with a cement or concrete slab. The heater must be installed on top of a suitable soft Insulation material. – Installing the heater between two hard surfaces will cause friction damage resulting in failure of the heating system.
Always use the foil strips provided to bridge any gaps when cutting and turning the mats. This is important to keep the earth intact.
Do not leave insulating materials such as bean bags; linen or towels on the floor surface.
Do not place heavy/sharp tools (or any other potentially damaging object) on top of the heating mats.
Do not install foil heating under and floor finish that is greater than 1 tog – Anything greater than 1 tog will impact the performance of the system and could cause overheating resulting in failure to the system.
Do not place items on the floor surface which will stop the air flow or not allow heat to rise into the room. – Thermal blocking will can result in the floor overheating resulting in failure of the heater and damage final floor finish.
Always ensure that the floor sensor is fitted so that the heater does not exceed the maximum floor temperatures allowed. – 27/28°C is maximum that most wood floor manufactures recommend.
Using other floor types with the foil heating system.
Dual overlay application
- Floor Finish (Carpet /Vinyl)
- Warmup Dual Overlay
- Warmup Foil Heater
- Warmup Insulated Underlay
Once the foil heater has been installed the dual overlay boards can be fitted.
Step 1 - Lay the 3mm base boards in a brick like fashion making sure that all the boards are tightly butted together.
Step 2 - Install the 4mm top board on with the adhesive side face down.
The top boards should be laid so that they overboard all the base board joints.
Push down firmly on the board to give a strong, permanent full-surface bond.
Do not use the dual overlay boards in wet areas – the boards will expand upon contact with moisture. If you want to use in wet areas, use WDOC (Warmup Dual Overlay Concrete).
Do not install wood flooring on top of the dual overlay system.
Do not use the dual overlay with any other heater but the Warmup foil heating system.
Always may sure that any adhesives/glues are suitable for use with underfloor heating and are fully cured before turning on the underfloor heating.
Do not install floor covering and or underlay that exceed the maximum tog rating of 1.0.
Always check that all flooring is suitable for use with underfloor heating.
