DIY Underfloor Heating | DIY Floor Heating Under

DIY Underfloor Heating is a great way to save money.  The unfortunate part is that the job must be inspected, therefore a permit has to be pulled.  To pull a permit you need to have a business license and a plumbing, gas, or heating ticket to do so.  Where I am from Radiant Heat in the slab is the one of the most profitable parts of being a plumber.  And at the same time if done wrong the job is a total waste.  If you can find someone to pull the permit for you then you can do this job yourself.  The easiest way to find someone is to pay them well for doing nothing.  I know that you may feel ripped off.

But if someone paid me $1.00 per foot of pipe, to pick up and drop off the pex, pull the permit, and come back to test the system prior to inspection, then I would do that.  At that price I would still be making good money.  On a 1000 square foot slab, you would be saving (or making) about $600 for only a day's work.  In this case your hourly rate would be much higher than mine.  The alternative is to be cheap at this stage and not do it and regret it forever, or to do it illegally and run the risk of $5000 in fines and 6 months in jail.  So many people do not want to do it this way, everybody thinks they should get something for nothing.  If you realize that everyone needs to make a living then you will be fine with these savings.

DIY Underfloor Heating

Your plumber will have picked up half inch pex pipe that has an oxy barrier.  This pipe will need to be ran at 6 inch from the exterior wall.  I make the first two runs at six inches.  Then I place the next runs at 10 to 12 inches.  Use tie strap to hold the pipe to the rebar.  Make sure the pex is tight to the rebar or it will float.  Cut off the excess tie strap or it will be above the concrete after pouring.  The runs can be no longer than 250 feet.  Make sure that you will make it back to your header each time without running out of pex.  If need be the runs can be a lot less than 250 feet.  Try to divide your space ahead of time, so that each run will be as close to equal as possible.  That way the system will be naturally balanced.  The loops will be equally spaced throughout the slab except for close to the header.  At this space there will be spacing of one inch or less.  This spot will be a hot spot, but this is the best way to do it, and the heat given off will not matter enough to do this another way.  

Watching plumbers do this, makes the job look easy.  If you do not want to do this yourself, you should hire a plumber.  This should be done in every new home built.  You will never get a second chance to have radiant heat installed once the floor is poured.   If you would like to learn more then there is an awesome ebook on the market called Radiant Heat Made Easy, and if you decide to buy this book through our link we will give you our free ereport 'Do you ask these 7 questions to weed out the criminal contractor'  and if you also buy another book from our ebooks list we will make you a lifetime silver membership of our products page.  This will give you discounts on any of our products for life.
