About your exclusive Sun in Winter


Our Story: Inspired by Warmth

With roots in radiant heating expertise dating back over a decade, SiW has evolved from a niche provider of household heat tracing applications to a trusted brand offering smart, user-friendly solutions. We started by addressing common winter woes – like chilly feet, foggy mirrors, and damp wardrobes – and expanded into comprehensive systems that prioritize comfort, safety, and energy efficiency.

SiW – short for “Sun in Winter” – was born from a simple yet profound idea: to deliver the comforting glow of sunlight even in the coldest seasons. Founded with a passion for innovative heating solutions, SiW specializes in radiant heating and heat tracing technologies designed for homes, hospitality venues, and commercial spaces. Our name evokes the gentle, reliable warmth of the sun breaking through winter clouds, symbolizing how our products provide targeted, efficient heat that enhances everyday life without overwhelming your environment.


Our Mission: Innovative Heat for Every Space

At SiW, our mission is to transform ordinary spaces into havens of warmth and well-being. We believe that heating shouldn’t be complicated or wasteful; it should be intuitive, sustainable, and tailored to your needs. By focusing on radiant technology – which heats people and objects directly rather than the air – we create solutions that are not only effective but also eco-friendly, reducing energy consumption while delivering consistent comfort.

Whether you’re a homeowner seeking personal warmth, a hotelier aiming for guest satisfaction, or a business owner optimizing commercial environments, SiW products are engineered to integrate seamlessly into your life. Our commitment to quality is evident in every detail, from patented low-temperature heat dissipation to plug-and-play designs that make installation a breeze.
