weekend projects

A weekend project for you guys with leftover parts..

Everybody is familiar with the wood subfloor notched for pex tube. Ever thought about putting some under your mattress? Use a night setback stat to get it warmed up an hour before bedtime, or a timer if you've got it balanced exactly right. Don't forget flex connectors between the mattress and manifold.

Most people spend 1/3 of their time there, so you might as well be comfortable. You can create multiple zones, if somebody wants their side warmer. Space the tubes closer at the far end if your feet get cold.

    Ask hot rod

    hot rod I'am sure had experimented with your idea ? I bet just about every square inch of his home has pex running through it by now :)

    radiant bed

    Someone posted pictures here, about a year ago, of a bed frame with radiant tubing installed. Someone commented that their wife made a fairly good radiant bedwarmer. I recall thinking that, since my wife is more of a hot-air bed warmer, whether I could convert her or install a more recent radiant model.

    to say, Aidan, that your wife does not frequent the wall ;-)

    Air Alternatives

    Aiden, have you considered adding some heat recovery ventilation with perhaps a carbon scrubber for bedside relief? Works well with a radiant system... :)

    Nice job, Bob. Looks like you guys are way ahead of me.

    However, if my wife makes me re-upholster my favorite recliner, there might be a couple feet of tubing added while it's apart.

    And maybe the couch too.

  • thanks Carl

    you hit the nail on the head. people laugh, even radiant guys snicker, when i tell them about it, but like you said you spend 1/3 of your life there. i think it makes more sense to heat a bed than any other application, including bathrooms. with nite setback and only the beds being heated at nite- think of the fuel savings. my 2nd floor gets down to about 50 degrees. on the hot summer nites the cool water draws heat away from your body, it's a beautiful thing. bob

    how about some pics of the piping arrangement, I remember you telling us of how you get the cooling done!!


    Outstanding !!

  • it dosen't sweat

    at all. i have used it for 2 cooling seasons so far. the pex is sandwiched between insulation and the mattress. it's a simple piping arrangement- primary secondary piping with a thermostat, relay, circ. pump, and a thermostatic mixing valve set to 120 degrees. bob

    That's the one!

    That's the one I remember. A brilliant idea. You can get electric underblankets, but they've got a bad reputation as a fire hazard. My mother had one, but never took it out of the box. Going to sleep under a 230V wrapping doesn't appeal, tukeys and bacofoil come to mind.

    I found out, a long time back, that if you sleep while you're cold, you wake up tired. The body is doing vigorous shivering to keep warm and the mind sleeps uneasily. How much more restful would a night's sleep be if you could control the environmental conditions (T, Rh) at the ideal level, like in those isolation tanks? The conditioned space would only be around 25 or 30 cu. ft.. The psychologists must have researched this one.
