For public and private domains

On many open-air areas of restaurants and cafés they’ve become part of the well know street scene. Decisive for any profitable outside-gastronomy is a decent load factor during an as large as possible portion of the year. Not only the length of stay increases and with that the consumption, but the outside capacity can also be utilized in the chilly autumn/fall or spring seasons. The pay-back time of such an investment lies as a rule between one and two heating periods. Furthermore, your gastronomy will receive more attention. This trend continues since the ban on smoking in restaurants and café’s.

The advantages of Alke sidewalk café heating:
-No inconvenient storage or changing of propane tanks.
- Space-saving placement on walls or ceilings.
- Immediately noticeable and comfortable heat-experience.
- Permanent usage of open-air areas, also on chillier days.
-Increase in customer satisfaction.
-Increased revenue due to increased capacity utilisation.
-Amortisation (pay-back time) possible after only a couple of months.
