Smart energy for hotels: cutting heating costs without touching the guest experience

August 1, 2025

Hotels are among the hardest buildings to run efficiently. Heating runs continuously through the season, rooms hold temperature whether occupied or empty, and there is rarely any centralised way to adjust settings across a site. As electricity prices rise, that waste becomes one of the largest controllable costs an operator carries.

Voltalis gives hospitality operators visibility and control over their existing electric heating and enables it to support the grid at moments of peak demand, cutting electricity consumption and carbon emissions at no cost and without touching the guest experience.

Brit Hotel Morlaix

Brittany, France · 49 guest rooms · radiators and towel dryers

A mid-sized hotel in Brittany welcoming business and leisure guests year-round. All 49 rooms relied on ageing, standalone electric heating that had become expensive to run, with winter bills reaching €2,500 a month from continuous heating in empty rooms and no way to adjust settings remotely.

What Voltalis did

We deployed connected thermostats across all 49 rooms, giving staff intelligent central control of radiators and towel dryers so they can manage heating remotely, anticipate arrivals and departures, and set temperatures room by room without visiting each space. Two technicians completed the installation in two days, with no construction work and no interruption to the hotel.

  • Heating electricity consumption down 30% (12 MWh) across the winter
  • Remote, room-by-room control from a single interface
  • Installed in two days, at zero cost to the hotel

“I would absolutely recommend Voltalis. The solution is free to install, simple to use, and the results are tangible. When you analyse the data over time, the energy savings are undeniable.”

— Florian Person, Director, Brit Hotel Morlaix

Lagrange Alpine Holiday Residence

French Alps · 72 apartments · 325 connected heating appliances

A 72-apartment holiday residence in the Alps, where occupancy swings hard between full weeks and empty ones. Heating, towel rails and hot water tanks ran continuously regardless of whether guests were present, a structural source of waste common to seasonal accommodation.

What Voltalis did

We connected all 325 heating appliances to the platform and made the estate responsive to occupancy, so heating now follows real use rather than running around the clock. Two technicians completed the installation in nine days, fully funded.

  • 15% less heating electricity consumption
  • Centralised control across all 72 apartments
  • Zero cost to the operator
