My first post on right here but not my very first time o your website. I’ve been gleaming a lot of of good use information off this along with other internet web sites.
I simply wished to share my OWB hookup and just how I am warming my spa. My boiler I got is just a 90’s Heatmor 200css model I traded labor from the close buddy for. We cleaned and refurbished it, it had sat when you look at the forests for quite some time unused. I additionally got some model of Thermopex from him which was additionally utilized. My system is run off one Taco 007 pump this is certainly from the end that is low region of the boiler. It runs 65′ to the house about 30″ down but areas and goes through the wall that is back of household to the furnace space. After that it feeds a 24″ sidearm, 40 dish ex for on need water that is hot after that it would go to the hot spa ex, that is the same tube design as my sidearm, after which to my forced air furnace temperature ex and returning to the boiler.
Total cycle size is roughly 300′ circular trip of 1″ pex. With nothing calling for temperature a Delta is had by me T of 4degrees. This is certainly with roughly 15′ of entirely exposed thermopex sitting on the top the floor and a temperature that is outside of.
The tub that is hot got at no cost and ended up being a giant PITA to wash but happens to be awesome to possess, young ones like it! Its a 1991 Calspa and holds 1200gal of water. We ensure that it stays at 104F 24/7 so that as you can view maybe not the cover that is best about it. We T’d to the supply that is 2 and paid off it to 1″ pex that visits the Taco 007 pump after which its paid down to 3/4″ pex towards the heat ex and then dumps in to the 2″ return line back again to the bath bath tub. I entirely 
bypassed every thing to heat up the bath tub. The thing that is only utilize that the tub was included with may be the pump to run jets and clean the spa on a timer. The heat kicks on / off having a high limitation aquastat T’d to the 1″ pex supply right before the pump. It really is a rather system that is simple did not simply simply take much to have functional. It’s been installed and operating for just two months now with zero problems. The bath bath tub is definitely 104F and we utilize it very often.
I reside in central MN therefore we happen seeing mostly teenagers as well as solitary to below zero weather. We have seen really difference that is little lumber usage with hot spa included on. We have an exactly 1/2 cord rack right close to my boiler therefore I could well keep really good tabs on usage. That is my very first year utilizing the boiler therefore regrettably burning green timber mostly and I also’m sitting at 1/2 cable every 12 times using the temps as mentioned above.
If anyone has concerns on what used to do the hot spa We sooo want to help you. This web site happens to be therefore useful to me!
