Miscellaneous questions

Can I use an uncoupling membrane with the NADWS cable ?


Warmup now offers our own DCM-PRO cable, which is a custom designed cable compatible with all uncoupling membranes.

Can I install my Warmup system directly on top of plywood?


This page outlines installation recommendations when installing over a plywood sub-floor.

Can I connect one Warmup heater to another in series?


Connecting one system to the other in series is often referred to as “daisy chaining”. Each floor heating system must be connected individually to the operating floor heating thermostat.

Can I connect more than one Warmup heater to a thermostat?


As long as all systems that connect to the thermostat do not exceed 15 amps, running multiple leads up the conduit to the thermostat location is completely acceptable.

Can a wooden floating floor be installed directly over the Warmup NADWS system?


This page discusses installation methods required for installing a Warmup heating system under a floating wood floor.

What type of thinset should I use with my Warmup system?


We highly recommend the use of polymer-modified adhesives, also known as “modified thinset.” Since the addition of the polymer compound creates a more dense bonding reaction during the curing process, this ultimately improves heat distribution. Acceptable tile adhesives include modified polymer self-leveler or thinset.

How Long will my Electric Floor Heating System Take to Heat Up?


It depends on a lot of factors, but a classic installation over ¾” plywood with NADWM mats would take about 30 minutes to heat from 60F to 80F. Click “Read More” for details.
