Our old milking pump got there slowly. With a new one and a warmer environment you can make a big impact !

Jonathan, it depended on the starting moisture reading and the heat we could get into the area, for the dampest areas we had to do 3 or 4 hours to make a difference. What was really interesting was as we dried one area the reading fell around it as the dampness in the core moved to the drier areas. Sadly we did most of this in the middle of a cold Belfast winter, if you were doing it in a warmer climate and had a new vacuum pump the time would be greatly reduced.

@@BottomUPBoats Thanks. I'm looking at doing ours next winter (we'll also be stuck with colder ambient temperatures). Interesting to see a nice low-tech approach. 👍

It can be easier to increase the temp rather than the pressure depending on how new your pump is. We had a heat pad both on the outside (under the rubber) and on the inside when we could get it in place to heat up the core. As per the chart on the video the more you have of both the better....

I'd struggle to get a meaningful mat on the inside of ours as it's small, but I can direct warm air at it - in October I had 25° on the outside surface of a keel stub (air temp 14°) from a 2kW heater blowing on the inside. Your video states electric blanket (for a bed?). I was anticipating using underfloor heating, which I would expect to deliver more heat but haven't checked.

@@jonathanwebb9862 you will have a lot more heat than we did. We had air temp of between 0 & 5 C when we did the majority of our work. It was not an electric blanket for a bed, it was a small fabric heat pad about a metre square. If you get 25 C i think you should have a good chance to boil the water out of the skin.

Boiling points for salt or fresh water?

Great question, I had not thought of the impact of the salt on the process prior to you point this out. Tables are done with fresh, if there was salt content it would increase the boiling point which would increase the pressure required to dry out the hull.

@@anthonypeterson5618 you are correct, sorry about that. I should have paid more attention to my chemistry class while I was as school, I have edit to the original reply to keep the information correct for other who may read. I will have to do some research into osmosis to see how the salt content changes as osmosis. From memory osmosis is speed up the higher salt content in the water. I can only assume that a high degree if not all the salt transfers into the hull with the moisture.

you are not explaining Osmosis properly at all.....its not a cemical reaction at all....just read up on osmosis....

Thanks for stopping by and for the feedback, I should have paid more attention in chemistry class. You are correct that both the chemicals dissolving in the water and the pressure that pulls the moisture into the core are physical reactions.
