hello; I’m thinking about a reno in a large ensuite. I currently heat my house with hot water heat through a boiler. I have no in-floor heating at this time, but am considering installing during the reno. I’m thinking of installing an additional loop for the ensuite (and add to it during a future bathroom reno) – using your warmboard in the process. I currently operate the boiler at 170 degrees during the cold months; and I’m wondering if the water temp will be too high for the floor heat??
Hello. Thank you for your question.
You are correct – running 170F water through a Warmboard system is much too hot. Most of our radiant heating systems run between 80-110ºF. The best method to bring down the water temperature for this radiant floor loop (loops), is to install a 3-way adjustable thermostatic mixing valve (we can recommend the Caleffi 521 as a good option) and a circulation pump. This will allow you to maintain water temps in the rest of the house while circulating lower temp water through the radiant floor panels.
If you have further questions, feel free to call. You can also ask for our Technical Director, Paul at 831.219.1011.
