There are a lot of suppliers of underfloor heating and underfloor heating systems in Sweden. Most are serious and deliver a good product, but there are still a number of points to consider before making your choice of underfloor heating and underfloor heating systems.
In general, you can say that electric floor heating in the floor is a good solution for renovation and upgrading. In case of larger areas or even the entire house, you should consider waterborne underfloor heating. The reason is the construction cost is set against operating costs. On smaller surfaces, it usually takes many years before a water-borne floor heating system begins to be profitable. On such small surfaces as in the bathroom, for example, there are other advantages of electric floor heating. There you will have a nice warm floor throughout the year.
With water-borne underfloor heating you will be warmed during the warm period of the year when the heat in the house is turned off. However, there are some underfloor heating systems where the bathroom is separated from the house's other heating. Please ask your supplier of waterborne floor heating about this option. It is also possible to combine a water-borne underfloor heating in the bathroom with electric underfloor heating on top.
The most common areas for electric floor heating in Sweden are as mentioned bathroom, hall, kitchen and outdoor space.
There is a lot of space usually that we want floor heating in some basements. Then there are a number of points to consider. If you have moisture in your basement floor, you will not solve the problem of underfloor heating. You may have a dry floor where the floor heating is installed, but instead the moisture moves to adjacent rooms or into the walls. If you have moisture in the floor, you must fix it before installing underfloor heating. Normally, you need to drain the ground to get rid of the moisture. Houses built before 1975 usually have no insulation under the basement floor. About 1975, isolation began with so-called elephant mats etc. Then the floor insulation has increased up to today's approximately 25 cm.
If you have a thick dry concrete slab, the floor heating works well even without insulation. Unfortunately, it's hard to know how an old concrete slab is molded. Often the concrete slab was cast on a varying surface and could be 8 cm thick on some parts and 15 cm on other parts. Under most houses there is a moisture migration. If the concrete plate is too thin, the heat will be removed from the moisture when the plate is heated.
The most appropriate thing you can do in these cases is to isolate your source floor. Either radical by digging out the entire floor and rebuilding it according to today's standards with proper insulation or by laying insulation boards on the existing floor. Most basements do not have much space under cover, which means that in the latter case you do not want the floor to build too much. There are insulating discs of different fabrics down to 10 mm thickness. The important thing is that you choose a disc with steam transmission. That's a disc that breathes. Then you can install your floor heating on top of the disc and flush or mold it.
That's why you never put a sealant in a bathroom in the basement. You can put it on smaller surfaces like in the shower or after the walls, but it is important that the source floor in its entirety gets breathable. Another important point is that you should never turn off the floor heating in the basement . You can lower the temperature to about 10 ° C during the summer, but do not turn it off.
Regardless of the type of underfloor heating system you have chosen, you have to wait 28 days after joining before turning on the heat. What we commonly call the cure or crystallization process requires moisture and takes 28 days. If you turn on the floor heating before, the moisture disappears and the process is interrupted. This means that you can vacuum the joints and that your tiles leave the floor. Wait 28 days and you'll have a wonderfully warm floor to enjoy.
There are manufacturers who promptly claim that you will never have underfloor heating under hardwood floors. Other wood flooring manufacturers have advantageously used floor heating for many years without any problems. However, choosing the right wood floor and the surface temperature of the floor should never exceed 27 ° C. The room's humidity is another important factor. You should avoid book and maple if you want underfloor heating under your wooden floor. These two woods are extra sensitive to temperature and moisture changes. Water-borne underfloor heating works well under wood floors and provides even heat if properly controlled.
Electric heating also works well under wood floors if you choose a type that provides even heat dissipation. You can achieve this by choosing electric heat on aluminum foil or electric heating cable with at least one cm filler over the cable.
If you choose electric heating, avoid laying mattresses, heavy heats, etc. on the floor for extended periods . Then something that is called thermal blockage occurs. D vs the heat can not take the road somewhere and the floor becomes much warmer than 27 ° C on the surface, which can wipe out and cause cracks in the wood floor. Electricity under wood flooring should never exceed 80 W / m2.
All floor heating system suppliers provide guarantees, but check what they mean. Underfloor heating, whether you choose water-borne underfloor heating or underfloor heating with electricity, is a lifelong marriage. It usually works year after year as long as the floor is left without anything happening. However, it is important that you have used by qualified electricians or authorized pipelines during installation.
Make sure your warranty is a so-called full warranty. This means that your bathroom, hall or kitchen will be completely restored in case of manufacturing damage. Some floor heating system suppliers only replace the damaged material. For example, with a new floor heating cable if your floor heating system in the bathroom is not working. Most of the cost of tearing up the floor, perhaps moving bathroom furniture and then restoring it all, is not included. Therefore, always check that the supplier of your floor heating system has full warranty and is insured to completely restore your room. The best suppliers of floor heating systems have their own insurance with guarantees and do not support your home insurance.
