Excellent! Very helpful, detailed, and easy to follow. I will be sure to leave a 14 cm border. 5 years ago, we laid heating cables connected to rebar, then poured concrete over it in our garage with Saltillo tile on top. The slab heats up during the day (we have solar panels), the garage stays cosy in winter, and wecdon’t have to worry abt the pipes freezing. Getting ready to remove the last of the wall to wall carpet in our master bedroom. Will run cable on an uncoupling membrane then tile over it. Wish I had done that in the rooms upstairs as well. Thank you for taking the time.
Very good video guys, im thinking of installing my own underfloor heating after experiencing for the fiest time in the epilepsy centre (weird thing to say but yeah) but yeah i didn't know the floor was heated and when i turned the thermostat up a bit as the room was cold i came in middle of the night to the bathroom and the floor was warm and then I i found out and now moving to my first home and in process of decorating it and everything and with such cold winters in the UK i want to invest in one for sure. Continue the great work
Great video, I have done electrical work now ten plus years, I never fitted underfloor heating though although the instructions seem easy I wasn’t 100% sure. However i want it in my conservatory once completed so will be adding it in very soon. Your video was clear and I will be referring to it if I hit a block
Great video. Very helpful. I would like to see how the tiles went down, a bit more of an explanation on the thickness of the tiling compound and what you do if the mats stick up. Thank you
Thank you. If the mats is sticking up you need to place a piece of timber over and remove it before the levelling compound gets really hard. There is a video on the channel about the tiles that we installed over this underfloor heating. (Herringbone pattern tile installation)
Brilliant video I'm going to be laying electric UFH myself but was worried about the electric install part but feel better how you tested it. Then carried on with laying it, screeding it then installing the final electric bit
Great video. Thanks! Question, can we put any display to a 4m2 floor heating mat? Are they all interchangeable? Can't find any info. Only that most mats and displays says 16A.
Hi , if you are talking about the thermostat you can have a different thermostat from the mats manufacturer. The only issue is the floor sensor. You need to install this from the same manufacturer as the thermostat otherwise they may not work. I’m n my opinion is best to get everything from one manufacturer. It is easier with insulation, warranty etc .
Hi Great video thank you. Please can you explain. Do you need to seal the joints on the insulation board with tape if there are small gaps and also does the whole thing needs priming again after the insulation board and electric mats before pouring self level
Hi , thank you If you have gaps you need to seal them . If the insulation is tight there is no need to use tape . This insulation is a tile backer board and doesn’t need a primer. It may differ from insulation to insulation.
Very helpful video. Thank you!Can I ask if you laid down the underlay before laying down the wooden floor? If so, which is the underlay you recommend to use with the underfloor heating? Thank you!
Hi On this job we have installed tiles not wooden flooring. For wooden flooring you need to install the insulation then the underfloor heating mat ( which is different from this one ) , then the flooring can be installed on top of the mat . No need for underlay but that also depends on what type of underfloor heating is used. If you need to use underlay you can use but only the ones designed for underfloor heating.
Hi For engineered wood I have used different underfloor heating system. This is for tiled floors. For wood you need to use something like this : www.theunderfloorheatingstore.com/products/warmup-foil-underfloor-heating-kit?dfw_tracker=170908-WLFH-140W/140&gclid=EAIaIQobChMI78rSlNrF_wIVku3tCh0YCwfWEAQYASABEgIOwvD_BwE This is designed for wood floors. It is ok but not as efficient as the tiled floor.
I'll be honest, sealing underfloor heating in with leveling compound seems like a nightmare waiting to happen, especially if there is a failure in the wire element. The underfloor wire element resistance might test well before installation but long term the wiring could be develop a hot spot and break or the quality of the element might have a defect that doesn't show until a few years. Also are you keeping the radiators? I thought part of the benefit was getting rid of the radiators?
This cables have lifetime warranty so no need to worry about this . In an event that one cable is burning there are ways to detect where and ways to fix it. If you have installed tiles before ( specifically the tiles from the video ) you will understand the reason for self levelling compound. There was one radiator kept as the rest of the house is still on central heating. It will help with the bill. The underfloor heating was installed to have a worm floor as it is very cold in the winter.
Hi The underfloor heating with aluminium foil is designed for laminate/wood flooring. Depending on the floor covering you have different electrical underfloor heating systems.
Great video! I'm just curious. I'm about to install a 35sqm area with electrical underfloor heating. It's for my wife's yoga studio where she will be running classes. Will a yoga mat, for the duration of a class pose a threat to overheating?
Hi I don’t think that will be a problem. There will be gaps between one mat to the other so the heat can escape. In my experience it’s not easy to overheat the wires . Some people have big rugs over and no problems.
@@DennisCollins79 If the concrete is nice and smooth you can lay your floor over. If you are laying flooring you have to use a different electrical mat then I have used in this video. You need to use: under wood electrical heat mat.
So how 2 matts was connected? 2 separate thermostats? Seems like 2 thermostats on wall? What if i want to install 3 zones Kitchen dining and hallway ro i need 3 diferent thermostats or i can connect all to one? And control everything on one thermostat?
So we had 3 mats connected in 2 thermostats. 10 square meters in one thermostat and 2 mats (7+8 square meters) in the second thermostat. You can connect all 3 areas in one thermostat. One thermostat takes about 15-20 square meters depending on the thermostat. That being said you can connect more square meters to one thermostat. But sometimes that creates more work for the electrician and is more expensive than having 2 thermostats.
@@iMeze 2 mats in one thermostat. There is just enough space to connect 2 cable in one point. There is another alternative to have a junction box and from the junction box one cable to the thermostat but in my opinion this is more complicated.
@@kestutisbaratinskas2634 To have just one thermostat will be more expensive because it is more work. Plus you need a decent size junction box ( accessible) . So this was the electrician choice and we went with this, client didn’t mind having 2 thermostats.
Hi For Wood/laminate flooring there are different underfloor heating mats. Search for underwood heating mats. Is the one with aluminium foil . So you have to lay the mat then flooring underlay ( suitable for underfloor heating) and the flooring on top .
What can go on top of wood boards, before laying underfloor electric heating, what are the steps exactly please, having wood boards as the base, then enginereed wood flooring as the last layer? Thanks loads.
Hello I am in process of installing water underfloor heating. As part of the project the engineer is also moving the boiler from kichen to garage. My question is when the project completed what kind of certificate and documentation should I get for the underfloor heating installation and for moving the boiler for my future record. Can you please list out what should I get from the company on completion please. Thanks,
Hi For the boiler re-position you should get a bill from the company with the specifications that they moved the boiler and also a gas safe certificate . For the underfloor heating you should get a written confirmation that the underfloor heating was installed by a authorised contractor just in case you will have to contact the manufacturer for any warranty issues.
Hi Yes , you can . At the moment is not more cost effective than the gas alternative. Maybe if you are thinking of having solar panels. Also if you are going to do underfloor heating on whole house you will need to run new power supply from the fuse board ( for the underfloor heating)
I have to cover 34 m2 and I have 4 underfloor heating 10 and 7 m2, 10 and 8 m2, how do I connect them all together, would you have a connection diagram? thank you
