Geothermal water/steam is quite corrosive; here's an article on it: https://www.mdpi.com/2076-3417/13/20/11549 From the article: Among CRAs, stainless steels (SS) are the most cost-effective, with the 316L grade being widely employed in geothermal heat exchangers [75]. However, 316L SS is not suitab...

I'm glad Otter is finally up there with you. Although somewhat sad it probably means we won't be seeing Otter at the B&W meet anymore. I hope Otter will be back together and steaming the sound (with photos of Sea Otters! ) soon. I won't make it back to B&W until at least after I retire, whi...

A below-surface discharge for a blow down should have a shutoff valve at the through-hull fitting; as with all through hulls this should be closed if the boat is left moored somewhere. If the boat is going to be operated in salt water or other waters unsuitable for the boiler, I'd fit a check valve ...

Interesting... thanks for posting a link to your blog entry! A very nice write-up. Here in the US, the most common fuel oil burner is a steam atomizing jet. These are adaptable to smaller boats where the electrical requirements of a household-style burner are prohibitive, and works well in salt wate...
