The first app of its kind designed for use with any iPad or iPhone, Slant/Fin’s “Hydronic Explorer” makes it easy for today’s heating professional to determine, in-home, the ideal equipment a customer needs for maximum comfort at minimal expense. Professionals simply enter a set of required measurements into the Hydronic Explorer to calculate the total heat loss, then go to the Boiler/Baseboard Product Selection Guides to determine which Slant/Fin product(s) best suit the customer’s specific heating load needs.
