What is Varme Underfloor heating and is it really worth it?
We’ve all heard of underfloor heating – a “mod con” that actually dates back to 5000BC. Since it was first used, it has adapted and evolved to suit the needs of modern buyers throughout the 7000 years.
A buyer of today has many options when it comes to 2019 underfloor heating, with both water and electric systems available on the market. We at Flooring Village sell Varme Carbon Film Underfloor Heating that’s suitable for around the home and in conservatories.
What is Varme Carbon Film Underfloor Heating?
Suitable for laminate and wooden floors, Varme Carbon Film system is a cost effective, unobtrusive solution to heat your floors. At less than half a millimetre (<0.5mm) thick and an included Depron underlay of 6mm (making the total height approximately 6.5mm), it is not dissimilar to a regular underlay (often 3mm or 5mm in height).
The carbon film is a thin layer that sits between a Depron underlay and a 200-micron dielectric membrane (plastic sheet). The Depron underlay ensures that the heat travels upwards into your home, rather than down into the subfloor, and the 200-micron dielectric membrane acts as a moisture barrier that stops water from reaching the underfloor heating, which would not only damage your underflooring heating, but also could cause sparks, fire and in some cases electrocution.
This product is manufactured in a UK based, BEAB approved factory.
How it works
When installing an electric underfloor heating system like the Varme Carbon Film underfloor heating, the carbon film is laid on top of the underlay (such as the Depron underlay provided with this flooring). This ensures that the heat travels upwards and not into your sub-floor.
The heating wires are then connected to the mains supply by a qualified electrician. A sensor will be placed into the flooring to help monitor and regulate the floor temperature. The thermostat provided controls the temperature of both the floor and the overall floor temperature and set the programmes of when you would like the system to turn on or off and what temperature you would like your room or flooring to be.
Unlike radiators or a fireplace/ hearth, Varme underfloor heating heats up a room evenly. A room with good insulation and a wooden sub-floor generally heats up to the optimum temperature within 30 minutes to 1 hour; on a concrete floor it will take longer (however, concrete sub-floors cool down slower as they retain the heat). Varme carbon film underfloor heating systems are supplied with a thin insulation layer and therefore it will not take any longer that 1 hour on any sub-floor.
Should I use 130W/m² or 160W/m²?
Varme Carbon Film underfloor heating is offered in 2 different Wattage options – 130W/m² and 160W/m². The 130W/m² carbon film is designed for any room in the house, whereas the 16W/m² is designed specifically for areas with higher losses of heat, such as conservatories.
It is important that you do not use 160W/m² in rooms with normal heating conditions/ losses as the additional heat omitted can cause damage to your floor, such as loss of moisture (drying), which may cause your floor to crack, warp or split.
Is it worth it?
Many people may wonder how expensive or inexpensive underfloor heating is to run, but this is a truly unique cost to each person. An estimate given by Varme is that their Carbon Film Electric underfloor heating costs approximately £3-£4 per m² per year if used as main heating and approximately £8 per m² per year in a conservatory.
Varme carbon film underfloor heating comes with a lifetime warranty for both the home and conservatory products. The included thermostat has a 5-Year warranty from the date of purchase.
Common Questions and Answers
How do I control the temperature and timings?
The floor and room temperature and timings are controlled using the included thermostat. The FH-01 thermostat has a 7 day/ 24-hour timer built in, meaning that you can set programmes for when you would like the Varme underfloor heating to turn on and at what temperature you would like the room to be.
Is Varme underfloor heating noisy?
The Varme carbon film underfloor heating system should be silent. If you hear a noise when the product is heating up or in use then please contact an expert for advice.
Can I use my Varme underfloor heating as a primary heating source?
Yes, it can. Underfloor heating is often more efficient that more traditional methods of home heating as it warms up evenly across the room; whereas radiators or fireplaces will heat up the area surrounding it quickest and will eventually heat up the whole room.
How long does it take for the Varme underfloor heating to warm up?
A room with good insulation and a wooden sub-floor generally heats up to the optimum temperature within 30 minutes to 1 hour; on a concrete floor it will take longer. Varme carbon film underfloor heating systems start to heat up within minutes due to their thin insulation layer. Please note that it should not take more than 1 hour on any type of sub-floor.
How warm will the flooring get? The Varme underfloor heating will heat the floor to a temperature of 27°C; this is the limit that most wooden flooring can be heated to without causing damage. The flooring will be warm underfoot but never too hot. Remember that the floor temperature can be adjusted using the thermostat provided.
Am I able to install it?
Yes, Varme carbon film underfloor heating is simple enough to install that anybody with even basic DIY skills is able to install it; however, a professional electrician MUST connect the Varme underfloor heating to the electric mains.
Is there a guarantee?
Varme underfloor heating comes with a lifetime warranty for both the home and conservatory products and the included thermostat has a 5-Year warranty from the date of purchase.
