Welcome to our forum.
Last night, went in the HT and turned on the jets and felt cooler water running out of the jet. The water turned warmer after serveral seconds (15 seconds). I have a HS Envoy, which 24hr circ pumps, and understand that the water is not moving through the plumbing tubs feeding the jets. I'm just surprised that the water temp would be noticable in a FF tub. The tub was used on Monday and Tuesday, so the water wasn't sitting for a long period of time. Plus in NY, the outside temp has been warm (60 degrees).Is this normal? I checked the water temp and it was 100 and felt the heater kick-on on last night as well.

Must depend on the type of insulation, mine does not do that. My tub is TP insulated and the inside cabinet stays between 100 and 114 all the time, it gets heat off the circulation pump and the Ozone light. It gets up to about 114 when the jet pumps run. I have a remote sensor inside and monitor the temp. The water is always warm when I first turn on the jet pumps.
But Bosco has an Arctic so why does his spa do that? In fact, an Arctic doesn't foam the shell from my understanding bu relies more on insulating the outer panels and bottom so I'd expect his to have this occur to the least degree compared to a full foam or standard thermopane. I'm a bit confused on the varying results but yes, it is common for the plumbing lines temp to be a bit lower if the pumps have been off an extended time.
