No matter if you have a big restaurant terrace or a small private one in your own backyard; you will spend a lot more time there if you heat it. So what are the secrets to get a good heating distribution?
By positioning the heaters around the open space and facing inwards you will get an even and comfortable warmth. Since radiant heaters only warm up the surfaces they reach, you will feel cold on your back when facing the heater. But with heat from at least two directions you will feel warm all over.
Output for open air or glazed patios
In an open-air dining area that is not protected from the wind, the output demand is high to achieve the level of comfort of the heating. Suitable radiant heaters are products with high element temperatures. Reckon on a power requirement of 750 – 1000 W/m². Glazed patios increase the chances of achieving a comfortable indoor climate, as wind stresses are eliminated, however, it can still feel cold. If there is no insulation whatsoever radiant heaters with high surface temperatures must be used. Reckon on a power requirement of 250 – 600 W/m² depending on insulation. If the space is sufficiently insulated radiant heating with low surface temperatures can be used. Supplement with stepless control/timer for best comfort.
Accessorize for a better installation
There are numerous alternatives for radiant heaters on the market today, in all kind of price ranges. Make sure from the start what you expect from your heater. Do you need to be able to move them around? Are they protected from rain and bad weather or do they need to be corrosion-proof? Last but not least are your terrace/patio built in a way that makes it easy to install the heaters correctly? If not, choose a heater with many mounting possibilities and adapt it to your terrace instead of the other way around. With accessories like posts, wires and different extension brackets you can make sure that the installation fits your terrace perfectly.
