Floor heating (床暖房) transforms cold winters in Japanese homes. This guide covers the top 10 floor heating manufacturers, the difference between hot-water and electric systems, and key installation considerations for landlords and homeowners.
Two Main Types of Floor Heating
Hot-Water (Hydronic) Floor Heating
Heated water circulates through pipes beneath the floor. Energy-efficient for large areas and widely recommended for whole-room heating. Requires an initial boiler/heat source installation.
Electric Floor Heating
Electric heating cables or mats heat the floor directly. Easier to install and ideal for smaller areas like bathrooms or entryways. Running costs can be higher for large spaces.
