How to heat complex or poorly insulated interiors?

Heating is most often seen as an element that is used to heat the air directly (heaters, air/air heat pump  etc.).

However, when the constraints are too important the traditional solutions are no longer adequate.

What are these commun constraints prohibiting conventional heating methods?

• Great heights (very high ceilings).
• Large open interior spaces (large floor areas).
• Poorly insulated, difficult to insulate or simply non-insulatable spaces.
• Premises with continual opening and closing facing the outside.
• Premises with covered outdoor and sometimes exposed to the wind.

What are the inside areas concerned?

These are:

• churches and places of worship,
• library,
• lobbies with almost permanent opening (department stores),
• sheds and warehouses with sectional doors,
• industrial or building sites, factories,
• gyms,
• garages,
• yachts and pleasure boats,
• similar spaces.

What are the covered outside areas concerned?

These are:

• atrium or patios, conservatories,
• outdoor eating areas,
• stadiums,
• verandas,
• terraces,
• balconies,
• similar spaces.

Heating solutions you should look for:

• with minimal servicing and maintenance.
• which do not heat the entire volume of air, but only dedicated areas.
• that will heat quickly and only when you need it in order to limit the consumption.

They can be stationary or mobile (support heater, terrace heater according to affluence, etc.).

For all of the above described building structures the solutions are common:
