Gas patio heater - Are they efficient?

[eveares]

I am looking at a 12Kw FireFly gas patio heater from Primrose, and just wondering how long will they run for on average based on a Full 13KG Propane bottle with a 12Kw burner on it's highest setting?

How does the efficiency compare electric patio heaters?

If efficiency is important to you I think you should reconsider buying a device that effectively tries to heat the entire atmosphere.

To heat one side of a person on patio you need radiant heat from the patio heater. It is possible that some electric patio heaters will give a better level of perceived "comfort" than a gas patio heater of the same kW output
