Wrenches, I'm installing a flat-plate SDHW system in my own off-grid home; a PV-direct closed-loop glycol system feeding a storage tank with two internal heat exchangers. The glycol lines only need to run a distance about 25' (each line), but they need to take a circuitous route through roof and attic framing that doesn't lend itself well to flexible copper tubing. I have heard very good general recommendations about the insulated flexible corrugated solar thermal line kits - expensive but worth it. One or two stainless or copper tubes with insulation and sometimes a sensor line included, with fittings to adapt to pipe thread or copper tubing. At SPI there were a whole raft of manufacturers showing product - I mostly just grabbed literature: Easyflex Solar-Trac by OmegaFlex Caleffi Aeroline Who has used this product? Whose product do you like? Needs to be well made and readily available to ship. Thanks for any advice; I need to get this ordered and in place before the insulation is sprayed into the roof. Allan --
