An outdoor or patio heater is the tall freestanding unit that keeps a terrace usable into the evening, and it is a block hospitality and landscape designers add when a plan needs to show how an outdoor space stays comfortable. This page offers a free outdoor heater CAD block in DWG and DXF, drawn to scale and ready for AutoCAD 2004 or later, free for personal and commercial use with no signup and no watermark.

A patio heater has a small base footprint but a tall presence, so it matters in both plan and elevation. In plan its round base and the spread of its heat reach decide where you can safely place it among furniture; in elevation its height sets the visual line over a seating group. This block lets you place heaters sensibly across a restaurant terrace or a garden seating area and show them on a presentation elevation.

What the outdoor heater block shows

The heater block represents a freestanding patio heater: in plan, the round base or weighted foot with the column rising from it; in elevation, the tall pole, the burner head and the reflector or canopy that throws heat downward over a seating area. The classic 'mushroom' gas heater is the familiar form, and the block reads clearly as that tall, top-heavy outline.

The plan footprint is deliberately compact — a heater takes little floor — but the useful information is placement relative to furniture and overhead structures. Drawing it to scale lets you keep the heater clear of parasols, awnings and planting while still close enough to warm the seats it serves.

Typical sizing and placement

Use these ranges to place the block. A freestanding patio heater base is commonly in the order of 450–600 mm across, with the unit standing taller than head height so the reflector clears people beneath it. The base is weighted for stability, which is why its footprint is wider than the slim column above.

For placement, keep clearance above and around the burner from anything combustible — parasols, awnings, low branches and walls — and leave a circulation gap so the heater is not in a walking line where someone could knock it. These are planning notes for layout, not safety certification: always follow the manufacturer's stated clearances and any local regulations for the real installation.

Plan and elevation use

For the layout you work in plan: the round base placed among the tables or the seating group, on its own layer so you can see the heat-source positions at a glance. For client presentations and section drawings you switch to elevation, where the heater's height reads against the furniture and any overhead structure.

The block is drawn full size in millimetres. Insert at scale 1 in a millimetre drawing, 0.001 in a metre drawing, or set INSUNITS to millimetres so AutoCAD rescales on insertion. Drop the plan base where the heater stands, and use the elevation view when you draw the terrace face-on so the proportions stay believable.

Where outdoor heaters appear

Patio heaters show up on restaurant and café terrace plans, rooftop bars, hotel and resort outdoor seating, event and marquee layouts, and private patios designed for year-round use. They pair with the outdoor dining set, parasol, planter and decking blocks in the outdoor category when you are dressing an evening-ready terrace.

Because the block is free and clear to use, it suits hospitality concept plans and tender drawings where the heating strategy needs to be shown. The same heater carries from an early seating-capacity sketch through to a coordinated outdoor FF&E drawing, so the heat sources are accounted for throughout.

Layering and counts

Put the heaters on a dedicated equipment or services layer rather than mixing them with furniture, so you can isolate the heat sources for a services or capacity review. A distinct colour makes them easy to count and check against the seating they serve.

If you tag each heater block with an attribute — a unit reference or a fuel type — you can extract a count straight from the drawing for a tender or an equipment schedule. When the terrace layout is set, you can WBLOCK a table-group-plus-heater module and array it down a long terrace so the heating is distributed evenly without placing each unit by hand.

Freestanding, tabletop and wall-mounted heaters

Patio heaters come in a few formats, and which one you draw changes how it sits in the plan. The freestanding mushroom heater this block represents stands on the floor among the tables, claiming a base footprint you have to keep out of the walking lines. A tabletop heater is a much smaller unit that sits on the dining table itself, so it barely affects the floor plan but does take up table space you would otherwise lay for diners. A wall-mounted or pendant electric heater hangs off the structure and frees the floor entirely, which suits a narrow terrace where a floor-standing unit would block the route.

When you plan the heating, it is worth noting on the drawing which type each position is, because they place to very different constraints — floor area for freestanding, table area for tabletop, and a suitable wall or overhead structure for mounted units. Using the freestanding block for the floor-standing positions and simply marking the wall or pendant locations keeps the layout readable and tells the services trade exactly what is going where. That distinction also feeds the equipment schedule, since a tender wants the count split by heater type rather than a single lump figure.

Questions

Frequently asked

Is the outdoor heater CAD block free to use?+

Yes. It downloads free in DWG and, where available, DXF, with no signup, no watermark and no attribution requirement, cleared for commercial use.

Does the block include both plan and elevation?+

Where a block ships multiple views they are in the same DWG. Use the plan base for layout and the elevation for presentation drawings and sections through the terrace.

Does the block tell me the safe clearances?+

No. The block is for layout and presentation only. Always follow the manufacturer's stated clearances and local regulations for the real installation around combustible items.

What opens the DWG file?+

It targets AutoCAD 2004 and later and opens in AutoCAD, AutoCAD LT, BricsCAD, DraftSight and free DWG viewers.
