Misconception: There have been suggestions that Radiant products necessitate CPVC venting due to high vent temperatures. This is not the case. Our industry-leading 96% AFUE rating ensures our products maintain lower vent temperatures. It is important to note that neither CSA nor any other regulatory authority mandates using CPVC vent material for Radiant products.


Misconception: It has been suggested that Radiant products are not suitable for areas with hard water. On the contrary, Radiant products showcase unparalleled resilience in hard water conditions, boasting an impressive rating of 15.6 grains. Thermal Hydronics Supply offers Filtro Water Treatment Products to enhance your system's performance further.


Fact: It is important to note that fluctuating hot water temperatures are not caused by our water heaters or manufacturing processes. Such fluctuations are typically attributed to deficiencies within the overall system. Rest assured; we stand by the quality and reliability of our products.
