The Cosmogrill Original 5 Gas Burner Garden Grill delivers serious cooking power with four 1.8kW stainless steel burners plus a dedicated 2.1kW side burner. This configuration provides 9.3kW total output across a generous 61cm x 32cm cooking area.
Built for convenience, it features enamelled grill grates that resist sticking and clean easily. The full-length warming rack keeps food at serving temperature whilst you finish cooking. V-shaped flame tamers prevent dangerous flare-ups and protect the burners from grease damage.
Practical storage comes via the spacious bottom cabinet with doors, perfect for gas bottles and accessories. Castor wheels make repositioning simple, whilst the built-in thermometer ensures accurate temperature monitoring for perfect results every time.
You need a 37-mbar regulator for propane gas (patio gas) or a 28-mbar regulator for butane gas. The regulator and hose are sold separately and not included with the barbecue. Most UK garden centres and DIY stores stock these regulators. Check your gas bottle type before purchasing as the wrong regulator pressure can affect cooking performance and safety.
Assembly typically takes 1.5 to 3 hours depending on your DIY experience. Whilst possible to build alone, having a second person helps with holding panels during attachment. The barbecue comes flat-packed with all fixings clearly labelled in individual packets. You'll need basic tools including screwdrivers and spanners, though an electric screwdriver speeds up the process considerably.
The 61cm x 32cm cooking area accommodates food for up to 10 people. You can fit approximately 8 sausages and 4 burgers simultaneously, or one whole chicken, or various skillets and vegetables. The warming rack provides additional space for keeping cooked items warm whilst you finish preparing other dishes.
The enamelled grill grates clean easily with warm soapy water and fit in standard dishwashers. Remove them after cooking whilst still warm for easier cleaning. The enamel coating prevents rust and food sticking, making maintenance much simpler than traditional steel grates. The removable grease tray underneath catches drippings and slides out for emptying.
The barbecue weighs 27.3kg when assembled, providing good stability in moderate wind. However, strong winds can affect flame performance and temperature control. The V-shaped flame tamers help protect the burners from wind interference. For very windy conditions, position the barbecue in a sheltered area or consider using a windbreak.
The four main burners each produce 1.8kW and heat the primary cooking area through the flame tamers and grates. The side burner delivers 2.1kW directly to pans or skillets placed on top. Use the side burner for sauces, vegetables, or boiling water whilst grilling meat on the main cooking surface.
The hood-mounted thermometer measures internal air temperature rather than food temperature. It's useful for monitoring cooking environment temperature and ensuring consistent heat levels. For food safety, always use a separate meat thermometer to check internal food temperatures, especially for chicken and pork.
The barbecue comes with a 30-day return policy for many issues. The supplier provides specialised customer support seven days a week via phone or chat. Many problems can be resolved without returning the product, such as supplying replacement parts for minor damage or manufacturing defects.
