Korean way of installing radiant heat over wood subfloor. Koreans having been using this heating for decades. electronic control can be expensive and prone to breaking down. simple manual valve to each circuit is good enough for hot water flow adjustment and good for your lifetime. absolutely no fancy control equipment. 1. install the tubing after all walls are done. each room has a separated circuit. no circuit in bathroom. minimum circuit on passby area. architect's drawing often make the install complicate. Just do it after all walls are done, then you would't risk nailing to the tube . to each room, lay in the order of the following material to the subfloor 1. a thin plastic or vinyl paper to have some concrete proof effect to the wood framing, vinyl should go a few inches up the wall above the final mortar level. 2. 2 inches thick rigid form ( usually pinky) Tape them to prevent mortar leaking 3. 2 layer of rebar net ( the cheap wire net, commonly used for sidewalk concrete) . 4. tubing ( plastic pipe) tie the tube to the rebar 5. 1 more layer of the rebar net on top of the tubing. tie them again to the bottom rebar. 6. a nylon mesh of the very flexible nature, sagging in its own and loose enough that mortar will flow freely into the mesh. Do not pull the mesh flat . loosely folded here and there . This mesh is critical to prevent the concrete from cracking. 7. pour the mortar, just waterly enough as to almost level itself. absolutely no gravel. pouring room by room is much easier to work. pouring whole floor at once? out of mind? good luck.
it's very common and traditional heating system in south-korea, which is called "온돌" (ondol, means warm stone). its history goes back to more than 2000years. in the old days it used stone, mud and smoke to heat the room and to make path upto the chimney. e.g.) put fire kitchen furnace->smoke goes through stone and mud tunnel->room heats up -> smoke comes out to the chimney but now days we make it like that way shown on the video. it's very good way in winter. it makes all the room very warm that's why korean don't wear shoes in the house and sleep on the floor.
Interesting we (central europe) never called that korean style but underfloor heating and I saw first example in 1970 but if you think a style on ancient system well than I could find that: www.ancientpages.com/2018/01/14/hypocaust-first-central-heating-invented-ancient-romans-2000-years-ago/
Definitely worth paying a good company to do this. The amount of underfloor heating I've inspected over the years that has been poorly laid or just thrown in is unbelievable. It's always worth paying for some thermal imaging afterwards to see how the floor is performing and to make sure the pipe runs are as described by the company/manufacturers instructions.

First Last its not really that nice because you have to wait about 10 plus hours for the heat to really get in the floor and if you want them hot in the morning you will have to deal with the heat while your trying to sleep so I only do other rooms other than the one I'm sleeping in
What is the difference between this and the heating Matt things. This is a larger pipe and spaced more apart but difference in efficiency? Heat wise etc? Can we see that
If you have the whole floor radiating out an even heat, this seems more efficient than a radiator as the surface area is so big? The air is warmed right above the floor and this is where the cold sits.... by directly convecting from the floor, does this lower bills by having a lower temperature and a much bigger surface area? Or am I over estimating the efficiency?
On the whole underfloor heating is approximately 25% - 30% more efficient than radiators. This is due to the larger surface area being heated and a lower flow temperature used. Feel free to get in contact with our team, we will aim to answer any questions you may have. 0333 800 1750
Korean "On-Dol" is a bit different than the Romans in that, Koreans didn't heat the floor the sake of heating a room. They took the fire in the kitchen for cooking, etc. and re routed to heat a room.
Hi there, This time-lapse video shows the laying of an underfloor heating screed system. The installers are a company that specialise in screed, they had pressure tested the system prior to screed being laid (just not shown). Pressure testing is important to do and should also be done for a second time prior to commisioning the system. If you have any other questions, please feel free to contact our team on: 0333 800 1750 Thank you.
All our systems consist of one long run of pipe which is always pressure tested before being set in screed. We very rarely see damage, unless someone has damaged the pipe by drilling/cutting the concrete etc.
Yeah I can see system failing due to lack of power for extended time during freezing system.... but that is kind of a rare possibility and if the pipe has enough flex then the freezing won’t crack the pipe
That was a great video. But a serious question. Isn't the person rolling the tubes on the floor going to fuck up his back after a few projects? My back hurts from watching this video. Although it was informative.
Hi there, In this situation, the pipe would need to be repaired with a coupler that we can provide. We would recommend replacing the loop though as it would reduce any issues that joining pipe may cause. When the repair is completed a full pressure test would be required. If you have any further questions please feel free to contact us through our website: www.ufh.co.uk or by phone: 0333 800 1750

Looks like a great job. Have you looked into using load compensation with underfloor heating ? Having a floor heat output perfectly match the room heat loss brings a new dimension to underfloor heating, total comfort and stable room temperature. Coupled with a condensing gas boiler load compensation and underfloor heating is a perfect partnership. In many cases the expensive room controls, actuators, pump sets and zone valves are no longer required. This reduces instalation costs and running costs while providing better comfort levels that traditional underfloor heating. Viessmann make the ultimate boiler and controls to partner underfloor heating.
I am aware my question is based in ignorance, which is why I am asking it, but why is PVC used as the underfloor piping? Wouldn't copper pipe conduct heat into the floor better? Is it used purely out of convenience of installation?
It is a good question and there are 2 main reasons that underfloor heating consists of plastic pipe. 1. Our pipe is 1 long length with no joins/connections (unlike copper pipe) so is incredibly reliable and not prone to leaks. 2. The plastic pipe does not corrode like copper pipe can.

It uses radiant heat, or radiation heat. It just makes you feel good and keep the humidity in your room stable. IMO it's better than using convection heat. Heated air coming through vents makes my room dry. and I think it is pretty economic even though the installation cost could be pretty steep, once you have the system installed in your house it is fairly cheap to run it depending on the insulation. If I had money I would definitely get it.
I will make you remove your carpet and footwear and walk barefoot on the floor and the best thing is you can sleep ditectly on the floor... this a unique korean floor heating system called "ondol" practiced thousands of years ago..

it is possible to use the exact same pipes. But You cant have both, heating and cooling at once. Few challenges may arise.

This is same korean houses. Most of korean house have this sistem.
Apparently (reading through the comments) this is common in South Korea.
All south korean houses uses these types of heating the floor system
It's names is 온돌
If only installations were as epic as that music track makes them seem. . .
This is a perfectly executed underfloor heating installation. Good guys and a really good job.
Here in South Korea they have been doing this for years. So many years in fact that before gas the use fire to make the floors hot in the winter

Is the finished pipe space 250mm? Or is that the first run then back in between giving a 125mm space. Thanks.
