Electric underfloor heating installation

This is a step by step video of how to install electric underfloor heating

[@d1nonlysnshn]

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.

Thank you for your message. Electrical underfloor heating is a great alternative specially if you have solar panels. All the best.

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

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

[@valentinointeriors3023]

Thank you . There is a nice feeling when you have a heated floor .

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

[@valentinointeriors3023]

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)

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?

[@valentinointeriors3023]

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.

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

[@valentinointeriors3023]

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.

thanks for the vid, if I only wanted to cover half the floor with the underfloor heating, do I just need to insulate board where the mats are? do I just use self level screed to level up the rest?

[@valentinointeriors3023]

@@rss2030 Hi . You can do that. If you do insulation board everywhere is a better result. This way you are not losing any heat and also it will be easier to get a level floor everywhere. It will not work out much cheaper to do levelling compound .

[@valentinointeriors3023]

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.

Hi David . I have used a spiked roller but not over the wires. The roller helps with taking the air out and also helps with the levelling.

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,

[@valentinointeriors3023]

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.

[@valentinointeriors3023]

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 .

[@noahpereira9766]

Hi have you had any success laying Engineered wood floors over the same system as in this video???

[@valentinointeriors3023]

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.

[@AlessandraTurso]

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!

[@valentinointeriors3023]

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.

[@Reprogrammed_By_SEGA]

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?

[@valentinointeriors3023]

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.

[@valentinointeriors3023]

@@dannykin9672 Hi. First you have to check the power of the thermostat. Normally the thermostat goes up to about 15 square meters of under floor heating ( depending on the wattage) . 2 x 25 m mats may be too much for one thermostat. The way that you connect the wires is the same like you have a ring circuit in a socket. So the mat cables goes both in the same place in thermostat. Very important to check how much watts the thermostat can take otherwise it will burn. If you have more wattage then the thermostat you can install 2 thermostats or hire an electrician. There is another way of installation with just one thermostat but I can’t tell you how to do it as I don’t know.
