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
