FAR INFRARED

Cost effective heating

By not relying on convection heat, Kelvin can keep your environment warm whilst using 30% less energy than traditional electric heaters.

Ensuring a warm and safe home

Kelvin is backed by years of research and development. An essential part of the R&D process was ensuring Kelvin is certified to the EN 60335-2-30 and EN 60335-1 standards. These certifications ensure Kelvin meets the highest European safety standards. All models also have an IP44 rating allowing them to be used safely in bathrooms and kitchens, where resistance to water splashes and moisture is needed. Kelvin also complies with the more recent EU Lot 20 Legislation around heating efficiency.

    HAVE QUESTIONS?

  • How do I install a Kelvin?

    accordion-icon

    Kelvin can be DIY installed in under 5 minutes with all screws and guides included in the box. For USA clients, we include dry-wall anchors for easy installation without any tools required. If you are not handy, no problem! You can get in touch with any handyman or local installer for quick and easy installation.

  • Where should I install a Kelvin?

    accordion-icon

    We recommend installing the Kelvin facing high areas of use. If it’s your home office, then the ideal positioning will be facing your work desk. This allows you to feel comfortable at lower air temperatures and maximise the energy saving capabilities of infrared heat.

  • How many Kelvin heaters do I need?

    accordion-icon

    That depends entirely on the size of the room you wish to heat and your ceiling height. We recommend the Kelvin Large heater for larger rooms of 10m²-19m² (107 sqft - 204 sqft) and the Kelvin Standard heater for rooms under 9m² (96 sqft) assuming a standard 2.4m (7.8ft) ceiling height.
