1)Which gunite body would I need to use to allow for a venutri system with no blower? I only see you review and discuss the 1.5 x 2 in gunite bodies and I'm not finding smaller bodies. 2) If I use a venturi system do I need a stronger water pump?
Hi Gage, the bodies that I use and have reviewed on my channel are the ones for the concrete or block tubs - they are the only only ones that I use in that type of build. For Stock tanks I use a smaller body which is a 1" water and a 1" air line. If you use venturi, no, you dont need a stronger pump - but I would recommend a blower - they are inexpensive in the hole grans scheme of things and the performance is so much better than venturi. - Thanks - Andi
This is helpful information. I have a pool that I am in the process of adding a spa with a spill over into my pool. I would like to be able to heat my pool with my heater still. Will I be able to still heat my pool with my existing heater or will i need two different heaters? I have a Hayward spa/pool heater now?
Really depends on the temperature that you want in your hot tub - putting cooler pool water into it so that it spills over is counter productive if you are trying to heat it up. I would have a divert on it so that you can stop the spill over and then just heat the hot tub. Then, arguably you can just have one heater and switch whether it heats the pool or the tub - hope that helps - Andi
Just built a hot tub for cabin heated by stainless steel stove . I want to add some sort of jets, either water or air and thinking air pumps would be easier and need less power to run cause Iam on solar setup. I read somewhere that the air would cool my water so was thinking of building a small enclosure around my stove and pump air from there. What do you guys think ? I have my tub mostly insulated cause we get cold winters.
The heat loss from the blower would be marginal to say the least - you would be losing more heat vertically whilst you were in the tub from the water. You can get heated blowers, but not worth it in my opinion, have very little impact or difference to a non-heated version - hope that helps - Andi

Thank you so much for your response! The reason I’m looking at Venturi is I’m making a system that works on 120v and 20amps or less.

Thanks Andi, any recommendations on a small blower?
I tend to use this one in most of my builds - parts4tubs.com/product/hydro-quip-silent-aire-blower-as-820u/
