Heatmor / Pressurize a HEATMOR?
« on: January 07, 2017, 10:01:19 AM »
I bought a used 200CSS, about ten years old. I'm tying it into my oil boiler in the basement. System pressure in the house system runs at about 25psi.
I know that HEATMOR says the furnace cannot be pressurized. I'm wondering if anyone has tried pressurizing any of these units? What would fail, if anything?
If anyone has successfully pressurized one of these jackets, I'd love to hear about it. Warranty issues don't apply so much to me since my furnace is old and I'm not the original purchaser. I'd love to send my house system water straight out to the HEATMOR, just like I did with my old stove, which was a homemade job with a little less capacity than the 200CSS. I'm not relishing installing the water-to-water heat exchanger and the additional circulator.
If it's absolutely clear that bad things will happen if I pressurize the 200CSS, then can anyone help with suggestions on flat plate exchanger sizing and a good brand for price? My loop from OWB to oil boiler is about 160 feet total in 1 1/4" copper and I need to transfer about 150--200K BTU/H.
