    Posted: 13 February 2010 at 18:43
My boat was delivered with four outlets for the heater - one in the aft cabin, one in the heads, one in the forecabin - and the main outlet under the saloon table.

While sitting at the table would mean burning your legs, going to bed in the forecabin would mean freeze the said legs off. (I am referring to when I am staying aboard when there is sub-zero temperatures outside and I am not actually not out sailing, just staying aboard. Everybody knows that this winter has been fairly cold)

So, I decided to move the main outlet further forward to blow out hot air in the aisle by the mast foot. This has three advantages, one being that it can be angled to blow some air into the forecabin, another that the 90 mm hose is prolonged by approximately 1,5 metres and the third that it makes the hot air more evenly distrubuted and not just concentrated to one point.

I kept the previous outlet under the table but put a 90/90/90 mm flap valve on the duct so it can direct a gentle stream of hot air in that direction.

So far I am very happy with this solution.

I don't know if this information is of any use to anybody but I thought I should share it nevertheless.

Johan

Hi Johan.

We too have often wondered why the yard did place the outlet to blow hot air into the saloo table. We will copy your solution. Thanks for sharing.

Hi Johan,
My memory says that I have an outlet in the forecabin. Have to look for it, if it has disappeared from the boat during the winter or, my memory plats a trick on me.
 
I like your solution though. I guess the airflow will be much better when not being stopped by the table.

I realize that I was a bit unclear when I wrote my post. I do indeed have an outlet in the fore cabin but it is very inefficient due to the fact that it is located a long way from the heater. In addition, its position close to the floor means that no hot air will reach the beds. You will see what I mean next time you turn the heater on on a cold spring night.

Now, both the fact that you can angle the main outlet to blow air into the fore cabin and the fact that just the last two decimetres before the fore cabin is 60 mm will help warming the fore cabin. The factory solution meant that the last 1,5 metres was 60 mm instead of my current 90 mm solution. I hope this made it a bit clearer.

Apart from the flap valve the 105 mm hole-saw was the most expensive part involved in the project. I paid a lot for just one hole! 105 mm is the width of the original hole and I couldn't find a hole-saw in a better size but if you look carefully at the picture you will see that the hole is a tiny bit too big. However, I am willing to lend the hole-saw to anyone who wants to save the cost.

Johan

Hi Johan.

If I understand you correctly. You are now able to export 105 mm holes as you have put them in stock to be lend out Tongue

I can expand your business Johan, to also include 127 mm holes. (I bought the expensive hole-saw to make holes fpr the 6.5 inch speakers)We can sell holes all over the world and the post and package cost will be close to nothing.
