super heater for absolutely windless corners

Hello everybody,
We have brought us the device for our covered terrace.
We are, alas, smoking and therefore sit outside in summer and winter.
At 5 degrees and in the immediate vicinity you hold already NEN whole evening out of.
From 5 degrees and less want to leave the heater no more 40 cm.
Here I have already read that another downstream pressure regulator (an adjustable and can be set to 70 MBR) can block. Thus, the heat output will probably increase. Unfortunately I did not find such a regulator and can to give any details.

As such, the purchase is worth for us absolutely, because without it would be even colder :)
