STEP-BY-STEP INSTALLATION




Basement conversion



How the unused basement with the cement slab floor was converted into kids playroom with heated floors.


 

 

300 sq.ft. of the basement cement slab floor.

Purpose of the room: kid's playroom.

 

ELEKTRA electric radiant heating chosen for:

 

  • Ease of installation.
  • Comfort.
  • Safety. Nothing but the thermostat high on the wall is exposed.
  • Relatively low cost.
  • DIY (except for the final check & 30 min. hookup completed by the electrician).
  • Turnaround installation time.
  • Energy efficiency.
  • No need for the maintenance.
  • Simplicity.
  • Reliability: 20-30 years of maintenance free service expected.

 

Two ELEKTRA MG100/12.0/240V mats. Each to cover 133 sq.ft. 

240V was chosen to have lower Amps setup. Each to pull 5.2 Amp.

 

Controlled by: ELEKTRA OJ MICROLINE UCCG-9991-EA line voltage GFCI programmable thermostat with the floor temp. sensor. 

 

First,  "Backerboards" were attached to the slab with construction adhesive and the nail gun. This is to help insulate from the cold slab and to save energy as well as allowing stapling the heating mats instead of using the hot glue gun if the mats were installed directly on the slab. 

 

 

 

 

"Backerboard" attached with nails and construction adhesive to the original cement slab with the radiant heating mat on the top:

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

82.5F in 15 minutes!


WHEN INSTALLING THE MAT(S):

 

  • DON'T CUT THE HEATING WIRE!
  • ONLY THE FIBERGLASS MESH CAN BE CUT, NEVER THE HEATING COIL!

 

 

MAINTAIN THE DISTANCE BETWEEN HEATING COILS! 

This is NOT OK:

 

1" IS THE ABSOLUTE MININUM. 2"-3" IS BEST.


Please remember: Electricity can be deadly and wiring done incorrectly can kill and start deadly and destructive fires even when "just replacing one small receptacle". 

 

YOU ARE DEALING WITH LINE VOLTAGE, not low voltage! 

 

NEVER EVER attempt to work or even touch the inside of the electrical components without being 100% sure that the power is disconnected!

 

If you are not an electrcian and if you have the slightest doubt about your wiring ability, please contact a licensed electrician and/or repairman before doing any diagnosis, repairs or installations. The products shown here are deemed SAFE and sound by various testing authorities but the wiring process can only be SAFE when done with safety precautions. Please read manuals and/or ask pros when not sure. Most of the simple installations shown here can be done by yourself or you can have someone qualified do it for you and THEN have the electrician check it and connect it to power.
