Floor Heating

Start every day off on the right foot

After a restful, cozy night’s sleep, wouldn’t it feel great to step onto a nice, warm surface? We think so. With hydronic radiant floor heating, specially-designed pipes circulate a customized fluid throughout the room (and building), keeping the floor – and your feet – at a constant, comfortable temperature. 

How can we help create efficiencies from the ground up?

These highly-flexible, multi-layer pipes are made by securely bonding an inner layer of material to an outer layer of polyethylene of raised temperature resistance (PE-RT).

Used in three- or five-layer floor heating pipes, DOWLEX™ 2344 PE-RT Resin builds on the traditional strengths of polyethylene to deliver a little something extra: 

  • Long-term hydrostatic strength at high temperatures with no need for cross-linking 
  • Excellent toughness and flexibility (even at low temperatures) for durable, extremely leak-resistant performance 
  • Exceptional surface smoothness for improved flow with reduced pressure loss and deposit/sediment formation 
  • Corrosion and hard water scaling resistance for added protection of aluminum or EVOH layers 
  • Potential real-time installation savings 

This proven, highly respected solution also meets or exceeds key performance standards: 

  • North America 
    • Plastics Pipe Institute (PPI) TR-4 listing of 630 psi HDB at 180°F (82°C) 
    • ASTM F2623 and ISO 10508 (classes 1, 2, 4, and 5) non-potable heating pipe requirements
  • Europe 
    • ISO 9080 for long-term hydrostatic strength 
    • ISO 10508 for hot water applications (all classes)
    • ISO 2578 for prolonged heat exposure 
    • ASTM F2023 and NSF P171 protocols for chlorine resistance

Plus, existing cross-linked polyethylene (PEX) pipe equipment can be easily converted to produce pipe from DOWLEX™ 2344 PE-RT Resin.

How can we help keep the comfort flowing?

As in-floor heating systems have advanced, the liquid used to spread warmth throughout them has evolved from plain water to optimized formulations of water and glycol.

DOWFROST™ HD Propylene Glycol-based Heat Transfer Fluid answers the unique challenges of radiant floor heating by helping prevent:

  • Freeze-up and/or bursting caused by prolonged power loss and exposure to low temperatures
  • Corrosion, scaling, and sediment that can
    • Cause leakage and/or system failure
    • Reduce efficiency/restrict flow
    • Damage pipes, pumps, and other components
    • Increase energy costs
    • Decrease service life

DOWFROST™ HD fluid offers excellent heating performance ‒ plus peace of mind ‒ to system designers, installers, businesses, and homeowners with:

  • Cold temperature protection down to
    • -60°F (-51°C) against freezing
      (depending on concentration)
  • Corrosion inhibitors, pH stabilizers, and other additives designed to enhance system performance and service life
  • Non-toxic propylene glycol to prevent accidental contamination of drinking water

Other products used with hydronic/radiant floor heating systems include: 

  • BYNEL™ Adhesive Resins (PE-aluminum adhesive) 
  • DOWTHERM™ Heat Transfer Fluids 
  • DOWFROST™ Inhibited Glycol Fluids/Coolants 
  • DOWCAL™ Inhibited Glycol Fluids/Coolants
