Looking for a cheaper alternative to the spray in expanding polyurethane foam to insulate my spa. Ive found the pour in variety to be much cheaper, though it will require a bit of work to make it insulate the whole spa. Ive only seen one other person do this on youtube but cannot find the video at the moment. wanted to reach out to yall and see if this is a bad idea before proceeding.

Thank you!

Howdy! first time on this forum, hope everyone is having a good day. I'm trying to replace the circulation pump in a Balboa EL Neptune (pretty sure that's what its called) Original pump in Hot tub was a Waterway cp-1/15-1n22a 3410020-0E motor The pump motor specs are labeled as follows 1/8 H.P. 230v 0.8A S.F. 1 1725 RPM Continuous run time. Just about every reasonably priced pump ive found (sub $200) is rated at 1/15 H.P. Does it matter? Should I spend ~$300 to get one rated 1/8HP even if the lower HP motor has the same RPM? also the one i keep seeing (Iron Might 3410020-1E) has a lower SF value of 0.63A Is this a big deal? top contender for replacement: https://www.walmart.com/ip/Gecko-Alliance-3410020-1E-Iron-Might-Circ-Pump-44-230V-0-8A/115706139?wmlspartner=wlpa&selectedSellerId=1582&&adid=22222222227046475627&wl0=&wl1=g&wl2=c&wl3=96531595610&wl4=pla-218879689010&wl5=9016858&wl6=&wl7=&wl8=&wl9=pla&wl10=113139572&wl11=online&wl12=115706139&veh=sem&gclid=Cj0KCQjw0rr4BRCtARIsAB0_48Ou_bwsIFM0jSFsDZtfPGZ9KGOZM3lUx4drDR7m_BK6TGXa5vWt9AkaAhUeEALw_wcB Pardon my naivety, first time Hot Tub owner.
