Infrared Heating - Which Panels?

Hey guys,

I'm pelretty sure infrared heating is the right choice for us to heat out sporadically used garden room /summerhouse thingy that were having renovated soon.

However, there doesn't seem to be tonnes of reviews of information on which panels are good, bad, over the top etc.

I wondered if anyone on here has looked into this and found much they could share.

At the moment my hunch tells me Hershal seem decent, if expensive based on competition... But that's not based on much really!

Any thoughts much appreciated
