Solar hot water collectors (Solar Water Heating Systems) interface well with radiant heating (radiant heated floors) due in part to the large thermal mass common to radiant systems. This mass provides an excellent storage medium for the energy generated during the day. At night, this stored thermal energy is slowly released into the living space and a steady, even, and consistent comfort level is maintained.

The environmental benefits are only one of many reasons why solar hot water heating/solar thermal heating is increasingly used in conjunction with radiant heating systems. Simplicity, efficiency, and proven performance make modern solar equipment an excellent supplemental heat source.

Sizing a Solar Radiant Floor System

There are several variables to consider when it comes to sizing a solar radiant heating system. Latitude, solar orientation, budget, heat loss, type of collector, domestic hot water requirements, esthetics, and performance expectations are all factors needing careful consideration.
