As of 2015, hydronic floor heating systems are considered the most cost-efficient option for floor heating in climates where heating is the primary concern. Hydronic heating can also reduce costs due to its efficiency advantages compared to convection heating in some situations.
Hydronic floor heating systems are generally more cost efficient for residential applications than air-based floor heating or concrete slab heating unless a significant amount of concrete is available. Since hydronic floor heaters radiate heat near the floor, they are also more energy-efficient in structures with high ceilings as compared to convection heaters due to lower heat losses from rising hot air. This can lead to overall lower energy costs for the hydronic heating system, especially if it is powered with a high-efficiency boiler.
