Increases score by 2-3 points

Clean tech specialist, Vestemi, has today announced that its smart heating control, Radbot, is now SAP accredited in the Time & Temperature Zone Control category and live on the SAP register.

On average, Radbot increases a property’s SAP rating by 2-3 points, making it an inexpensive, unintrusive way for builders, landlords, and social housing organisations to improve the EPC ratings of their housing stock.

Stephane Blanc, CEO, Vestemi says: ‘SAP accreditation not only proves the effectiveness of our product, Radbot, but it also gives us even more opportunity in the residential property market. At a time when saving energy is more important than ever, Radbot offers the best value energy savings for every pound spent.’

As a smart TRV, Radbot is a quick energy ‘win’ for householders as it automatically heats rooms when occupied and reduces the temperature when empty, saving money and energy.  Plus, with all the technology built inside Radbot, there’s no need for apps, programming, or even WiFi.

Endorsed by the Energy Saving Trust and Energy Efficiency Award – Product of the Year – 2019, Radbot is also on the shortlisted for 5 key awards.

What makes the smart heating control stand out is that it is breaking ground, not only because of its simplicity and ease of use, but its ability to save money and the potential for carbon reduction at scale.

Not only is Radbot now SAP accredited, but it is also eligible for the Green Homes Grant scheme. This means landlords, homeowners, and Local Authorities can access funding to put towards purchasing Radbot.
