heater craft question

[bergermaister]

We've used the crap out of heater this year, so much so the tubes need to be replaced...

I have the 4 port version, with 4 tub heaters and one fixed vent driver side floor near your feet. The three tubes are in the walkway and 1 behind the driver seat. The weather around here has mostly been in the 60's all summer so we've had the heat on most days...

Where you located?

I'm wondering if a heater would extend our season at all - and if it would be worth it.

I don't understand this heater thing at all. Now A/C, that might make some sense.

I've seen one of those A/C thingies before in a store... You set your beer in front of it to keep it cold?
