Common Applications
Ecolite 24V Floor Convector - LZT/TZT
ISAN by Siwa’s LZT/TZT are a great emitter of heat and given the multi-pass, high efficiency heat exchanger designed specifically for low water temperature applications (Condensing boilers or water-water geothermal heat pumps) along with it’s architecturally designed casing and grille options, make this product a must have in any building wanting to achieve significant energy savings and lower heating costs. By using a 24VDC tangential fans, the airflow is 99% uniformly distributed across the entire heating element surface area. This allows for a higher GPM to follow through the multi-pass heating element as the added airflow speeds up the heat transfer into the space compared to natural convection.
Additionally, these Siwa low water temperature convectors provide better comfort by emitting heat more evenly and gently throughout the room. They eliminate the discomfort often associated with sudden temperature fluctuations and reduce the likelihood of drafts or hotspots. Furthermore, these convectors are compatible with modern, well-insulated buildings that require lower heating loads. They can be easily integrated into radiant floor heating systems or used in combination with low-temperature radiant panels, offering flexible and versatile heating solutions. Overall, the advantages of low water temperature convectors encompass energy efficiency, improved comfort, and compatibility with modern building designs.
