Flymo FH20B
Best OverallPros
- High heat output for large areas
- Sturdy base and anti-tilt switch
- Easy ignition system
Cons
- Requires propane gas bottle
- Heavy to move around
The Flymo FH20B is a powerful gas patio heater designed for medium to large gardens. It produces 13 kW of heat, enough to warm an area up to 20 square meters. Owners on Amazon and Argos praise its quick heat-up time and the safety features, including an automatic shut-off if tipped over.
Assembly is straightforward, though the unit is heavy at 12.5 kg. The stainless steel burner and powder-coated finish hold up well in outdoor conditions. Some users note that the gas bottle is not included, which adds to the initial cost.
Flymo FH15E
Best Budget ElectricPros
- No gas bottle needed
- Lightweight and portable
- Lower running cost
Cons
- Lower heat output
- Requires outdoor power socket
The Flymo FH15E is an electric patio heater ideal for small patios or balconies. It delivers 2 kW of heat, sufficient for a small seating area. Reviews on B&Q and Amazon highlight its quiet operation and the convenience of plug-and-play use.
It features a halogen bulb and a reflector to direct heat downward. The unit is lightweight at 4.2 kg, making it easy to mount on a wall or stand. The main drawback is the limited coverage area, which may not suit larger gatherings.
Flymo FH25G
Best for Large PatiosPros
- Highest heat output in range
- Wide coverage for large areas
- Durable construction
Cons
- Heaviest model
- Higher gas consumption
The Flymo FH25G is the most powerful gas patio heater from Flymo, with 14 kW output covering up to 25 square meters. It is built for large patios or commercial use. Owner feedback on Amazon notes that it heats up quickly and maintains warmth even in breezy conditions.
The unit has a large reflector and a robust base for stability. It is the heaviest at 14 kg, which can make repositioning difficult. Some users mention that the gas bottle lasts for about 10-12 hours on the highest setting, so running costs are higher than smaller models.
Flymo FH10C
Best Compact GasPros
- Compact and lighter than other gas models
- Good for small to medium patios
- Easy to store
Cons
- Lower heat output
- Stand feels less sturdy than larger models
The Flymo FH10C is a compact gas patio heater designed for smaller spaces. With 10 kW output, it covers up to 15 square meters, making it suitable for a couple of chairs. Reviews on Toolstation and Amazon mention it is easier to move than the larger FH20B.
It uses the same propane gas system but is lighter at 9.8 kg. Some owners report that the base is not as heavy, which can be a stability concern in strong winds. The heat output is adequate for mild evenings but may struggle in colder weather.
Flymo FH18R
Best Radiant HeatPros
- Radiant heat feels more direct
- Adjustable heat settings
- Good build quality
Cons
- Narrower heat spread than FH20B
- Gas bottle connection can be fiddly
The Flymo FH18R uses a radiant heating element that provides a more focused beam of heat, ideal for directing warmth to a specific seating area. It outputs 12 kW and covers up to 18 square meters. Owner reviews on B&Q highlight the adjustable heat settings, which allow for better control.
The build is solid, with a powder-coated finish that resists rust. Some users find connecting the gas bottle to be slightly tricky on the first use. The heat spread is narrower than the FH20B, so it is best for smaller groups sitting close together.
What to check before buying a Flymo patio heater
First, decide between gas and electric. Gas models like the FH20B offer higher heat output but require propane bottles and have higher running costs. Electric models like the FH15E are cheaper to run but produce less heat and need a nearby outdoor socket.
Second, measure your patio area. For spaces under 10 square meters, an electric heater may suffice. For larger areas, a gas model with at least 12 kW output is recommended. Also check the weight and portability if you plan to move the heater frequently.
Mistakes to avoid
A common mistake is underestimating the gas consumption. A 13 kW heater can use a 13 kg propane bottle in about 10 hours on high. Always factor in the cost of replacement gas bottles.
Another mistake is placing the heater in an unsheltered area. Wind can significantly reduce the effective heating area. Position the heater against a wall or windbreak for best results. Also, ensure the base is stable to prevent tipping.
