Many people like these as the sauna gets to maximum temperature in 10 minutes to 15 minutes, with 10 minutes on the smaller ones.
NOTICE. WARNING. BEWARE::::
There are some saunas that have carbon heaters that don't get hot enough and some saunas put in rods to make the sauna hotter when actually if the carbon panels got hot enough it wouldn't need rods. The rod/carbon saunas that I approve of only use it to get the broadest range of 7 to 14 microns while most or more common ones have 8 to 10 microns. Most of the big name brand from sauna makers that have been in business for 10 years or more usually have the higher end heaters. Its the name brands that I have never heard of.
Depending on how deep someone wants their sauna's far infrared to penetrate in the body, some only penetrate 1 to 1.5 inches and some even 2 inches deep in to the body. These are things that many people can't just read and know what its like to have that one inch difference. Its kinda like when getting a massage you want them to use more pressure but its just not enough because they aren't strong enough. Having lower fluence carbon panels where the rods are there to make sure the sauna is hot enough is like having.
If you think you would prefer a combo sauna, please review the different types before you buy. Just make sure the rods aren't there to back up an inefficient carbon panel. Any brand that has doubled back to back carbon heaters usually heat up enough and give off a high enough fluence to have no need for rods. But, rods give off what carbon can't give. Each type has their pros and cons. They either go deep into the body or don't have the full spectrum or vice versa. The new trend to back up heaters with 2 heaters together have nearly double the fluence and do get the sauna hot enough. Having 2 high end heaters back to back I don't need to have a rod heater. But, having a rod heater with 2 high end heaters makes sure the full spectrum is always there.
