I never realized how ingrained you and Athena are into my Sunday routine. It was so weird drinking my coffee without a fresh dose of spiffiness last week. Glad you're back and feeling better! Also, that shot of Athena in the beginning she looks so shiny and beautiful, really, really great job on the paint.
Jessi I had the same experience, pacing around my iPad wondering how the next spiffy video was coming along? Hoping Mads didn’t have Covid, regards from 🇨🇦
Yes! You were sorely missed last sunday! Welcome back.
Welcome back! Exhaust suggestion is keeping it centred on transom so it's always same height above sea level no matter angle of heel when under way. Best of luck
I thought about that, but will that get in the way of his wind vane steering? Looking at his device in older videos, it mounts up and down along the center of the transom too (unlike other vanes, that mount with four points spread out in a box like shape).
Welcome back to the land of the living :). Glad you're feeling better.
Glad to see you back Mads. Hope you feel better soon.
if i do say so myself, its good to have you back. :)
Mads, good job. Points to consider - a "sealed" system will be easier to vent, have less tendency to sludge, occupy less space as the expansion vessel will only need to be small (4% of the total volume and the pressure variation should be no more than 0.5bar - 2bar). Inhibitor can then be added and basically forgotten about and you'll have no issues with boat movement, frothing/aeration in the vented expansion tank, plus no evaporation and so on, it's normally a no brainer. A temperature and pressure relief valve is all that is then needed discharging to a safe place (I would suggest bilge). I don't know the heater but if it is modulating keep the circulating water as small as possible for response times. The boat, even with insulation is going to be cold but will heat up very quickly so a modulating burner would normally be an important consideration rather than just running the water at a constant temperature. The circulation pipes looked suitably small bore (10mm?) which is great for small volume and response times. Make sure the pump (integrated?) is accessible for servicing. The accumulator tank is a strange one to me but is obviously part of the manufacturers instructions and requirements - follow them. Fit quality isolation valves everywhere for ease of servicing - full bore and temperature rated, butterfly valves save space. Lag pipework where you don't need heat. Heat loss from pipes can be a pain but it will stop condensation and mould in cold climates. As high up on the transom as you can - the exhaust is not designed to mix with water and flue temps should be low-ish (condensing boiler?). A water trap may be required. We have a standard electric water heater and two Eberspaecher which blow very hot gases which means a lagged exhaust, but there are no complaints with the shower and heating! Good luck!
Hi Mads. I'm the norwegian guy with a Bavaria 39 that visited you onbord Athena in Skive harbour i 2019. I have had a water based heating system in my boat for some 14 years now and I love it. My system is somewhat different. I use a 5 Kw Eber burner and the engine via a heat exhanger to warm up the "system water", but I also have a calorifyer in the loop. This has also a 230 V heater element and I use this from time to time when shorepower is available. The system water runs in two parallell 19 mm isolated lines (port and starboard) and I have set up 7 of similar fan-heaters as yours. Each heater is set up with valves for adjustment or cut off. A small expansion tank (about a gallon) is placed in the engine room as the highest point. The system contains only 13 liters anti freeze. I have two serial connected pumps in the system. One is controlled by the Eber heater and the other starts when the engin starts as well as with a manual switch. The two cirkulation pumps makes it also easy to get air out of the system. The system has worked fine all this years, but I have had trouble with the Eber (had to change it two times). Using the boat mostly for heating water for shower and dishes, we normally run the Eber for 30 min. Then we have 60 degrees in the calorifyer and plenty for showering. When the sea water is cold, heating the boat is necessary and normally the heater do not start and stop too much.
But since you plan to use your boat for liveaboard in cold clima, I fully support your choise of a heater with variable effect. But you will also use the engine many hours and using the heat that it produce would be an advantage in my opinion.
Regarding exhaust: I recommend the place you first pointed to. I don't think the mooring lines will be a problem, but make sure you don't hang fenders there :-)
Can you run an eberspatcher on fresh water and use it for radient heat? Also the dometic runs 15k btu on low, I believe the eberspatcher goes down to 5k btu, thoughts?
@@rogerkerkmann Yes, I'm sure you can run it on fresh water, but if you have the boat i Norway - as I do - the freezing temperature is the problem when not in use :-)
My heater is rated at 5 kW - around 17000 btu I think. It regulates itself down to about half of that - can not be set to run permanent on half speed.
Glad you are feeling (a little) better.
One of my favorite Sunday treats. Pretty dang spiffy. Thanks. See you.
same
We had the same set up in our lorry but webasto diesel we found not have any stored hot water was a problem if we wanted to do some washing up we had to fire the heater up which on and off isn’t good for them. We removed the heat exchanger and fitted a calorifier in its place good thing now w3 have hot water for at least 20 hrs after heater is off and if we are on shore power it has an immersion heater in it so we don’t need to run the heater. We also dump excess solar power into it.
I wish the x30 had been available when I installed my X45 several years ago. Except for one small hiccup that the manufacturer covered it has been working flawless for 8 years. I use it also to heat my domestic hot water for bathing and washing dishes instead of engine heat. So we can turn those nice fan coil units off for summer and still have hot water. I also installed heat sensors on the fan coil units so the only start blowing when the water is up to temp. Good luck with your install, it will be one of the most satisfying installations for your boat. Enjoy being warm.
Glad you are back I thought there was a glitch in the matrix when there was no saillfe video last week ,👍😁
I hope you continue to recover and feel better soon.
We have had two heaters on our boats. First exhaust was right where you started, by the docklines. One melted howser on a cold winter's night in Catalina was a lesson learned. The second, on the boat we have now, is on the transom and right above where the dinghy would tie and where feet could get more than toasty! Will be a good challenge to figure that one out.
I just generally give your videos a like before I watch them. Over the years, you've never disappointed.
Ha same!
I generally like all the channels I watch regularly and I always Like the video before it even starts. Don't understand how a video can have over 18K views and less than 3K Likes...
I forget to like when using the fire stick a few clicks and no comments ether
I'm kind of surprised more companies are banging on your door -- or companionway wash boards - with free gear. You're meticulous, you read the directions, and you do fantastic work.
Glad to see you are feeling better. Stay well Mads. Missing my Sunday Sail Life fix is 💩. 😜
Someone else mentioned return air openings. Proper placement of these can also dry out bilges and wet lockers, as well as helping to provide even heat distribution throughout the boat. Avoid engine rooms, fuel storage areas, etc which might contaminate the interior air.
Glad your feeling much better
Nice to see you back Mads. Glad you are feeling better. We have a catamaran with a eberspacher would love this system, the advantage of running hoses instead of ducting would save loads of room and the hot water another huge advantage. Trouble is paying for it all... £4000+. Way out of most sailors/cruisers budget
Center of the stern if posible. On the side would be in the water when healed over
Surely all exhausts should be through the transom and roughly on the centerline. You don't want to immerse an exhaust outlet when the boat is heeled over. Ooops! Sorry, almost identical to the post above!
I am doing the same head scrating myself.
Thruhole on the stern. It’ll be mostly dormant while you’re in climates conducive for swimming. Hope you’re feeling better soon. 🇨🇦
It is so awesome seeing you walk to Athena in the water Mads...It is so encouraging to see 😊👍
The expansion tank should be closer to the centerline. Also I'd put the big tank underneath the cabin sole for lower center of gravity and a bit of floor heating.
The 'on demand' water heater is a good choice. Not only will it save electricity by not having to constantly heat water in a storage tank but the storage tank would take up a good amount of space depending on how much water you want.
Mads, place the exhaust outlet up high on the side of the hull. I have an Espar diesel heater with the exhaust on the transom. Airflow with the bow into the wind (at anchor) causes a low pressure back circulation of the exhaust which allows some exhaust fumes in the cockpit.
Good to see you back Madz.👍 Just one teensy weensy suggestion - if you see a cockpit tent in your future consider another pair of heating pipes from your manifolds - see RAN’s latest mod. Gives you can extra room on the boat for 7 months of the year if you are in Northern Europe.😂⛵️
smart!
Wow! She looks great on the water!
It's great to see you up in action again. Stay healthy and take care of yourself. Your health is more important than putting out a video.
Great to see you back 👍
Nice to have You back :-)
Great episode.
Winter up north, sail south for sun and fun. Summer time sail north. Seems like a logical and a lot more desirable approach to me.
Welcome back!
If you can pull the return pipe from the radiator in the bathroom in a loop benieth the floor boards you will get some really nice floor heating in colder climes. We lived aboard our Bavaria 42 in Göteborg during 4 cold winters and we loved that luxuary. Just put som insulation benieth so you dont warm the ocean instead.Took me like 30 min extra and soo worth it!
Great work!
Glad you’re feeling better.
Always a joy to watch , get yourself fit and well .
Excellent work! Looking forward to finished product.
Great job as always , Mads! Gett well soon!
The most important thing is the ventilation! Not only inside the sailboat, but also the air in and out of the sailboat. Without good ventilation, you'll get condensation! A LOT!
Kind regards.
Another great video thanks and get well
Love that lighting Mads
Get better. Missed you last week.
I'm excited about the interior look. Its something that I was curious about for a while.
Glad your feeling better.
Good to see you again. 😁👍
Glad you getting awesome job you are doing.
Welcome back Mads! Glad to see you spry! Great video!
Assuming the 6400 and 6000 numbers indicate thermal power, you should put the saloon and forward cabin on a separate circuit. You want an equal temperature drop in every circuit, that how you maximize efficiency. The hydraulic resistance of every circuit is going to be quite similar, so they are all going to get the same flow, in the diagram you are going to extract twice as much heat from one circuit than the other two. So the exittemp of circuits 2 and 3 will be higher than that of one. Then all is going to cool in the buffer tank, so all that heat is lost. (oh, and please insulate the buffertank).
Glad your on the mend, we missed you.. 👍
Glad you're feeling better. Take care of yourself.
Take care of yourself and feel better, great video. Thank you!
Well done!
Your heating system is looking like it will be fantastic, colour me envious!
So good to see it in the water in the opening
I'm really glad that you are well again, I was missing your video.
Great channel. Consider adding heat in the cockpit. You'll appreciate it when you install an enclosure.
we are trying to find a good way to do that too
I know !! That's where to put the exhaust😁
Its Wild seeing Athena in the water. LOVE IT!!
I like you man and your videos, free advice, Merch is not a word.
Hope you’re feeling better. 👍👍👍🤞🤞🤞
Merry Christmas to both of you!
I can “hear your sick” in the video. It always sucks when you’re not feeling 100%. Hope your recovery continues and we get to see you next Sunday for a “visit” because your back to your usual self. Be well.
Thanks for entertaining us although you are under the wind - take care of you !
If the fans are noisy and you don't like it, you can rubber mount them. There's these T pegs made out of rubber that you can buy online, and the legs are plastic. That plastic has 3M red double sided tape, so you can mount them anywhere you like. Cuts a lot of the noise, which is vibration.
You also need a hole through which the air to enter, not just exit. Just letting you know.
Mads, in addition to the vent on the cockpit I would put the heater exhaust on the right and move the ladder to the other side unless there is a reason it needs to be on the right.
I hope you feel better soon!!!
Glad you are feeling better. We missed you last week.
Nice one Mads. I'm really looking forward to seeing how the heater works out. It looks like a great piece of gear.
Pleased you’re back on deck. Hope you stay well and thanks for another great video.
Hope you get feeling better!
You’re back!!!!! Man you had me worried... so glad you are feeling better.
Good to see your back on your feet Mads, slow is ok till your feeling 100% again. I like that heating system and all the good thing's connected to it for hot water, long hot showers would be awesome and the secret is safe with all of us here, We Promise. Stay safe and Hope the Holidays are terrific for you and yours !
Glad you are well and thank you for the video.
To cut down on future heating cost, make some kind of heatexchanger for the exhaust. If it's hot, it means that you have a (big) loss.
Your boiler looks like it have the same heatexchanger as the airheater type. (like webasto) These heaters have a efficiency of only 50%, meaning that they throw 50% of the heat right thru the exhaust and out side.
Get well soon!
Nice job!!!
I’m looking forward to seeing this work. I’ve been wanting to install a hydronic heater to my diesel truck to preheat the engine in the winter.
Get well soon sir!
Cheers from Southern California USA ~
My third year of getting my dad some merch for Xmas. Thanks Mads.
I hope you get better! 💪💪💪😃
Definitely on the stern,safer from heeling,feel better.
Sorry to hear you've been ill, but very glad you're recovering - god bedring! :)
Glad your doing better Mads. I just want to say that the interior lighting looks Awesome! Great work as always. Wouldn't be a great Sunday without you.
This comment is to show the algorithm that this is a good video, and deserves to show up in search.
Nice video, get well soon
Damn good looking boat.
Wow, in the water Athena looks amazing.
Glad to see all the progress you're making. It's amazing to see your commitment to the project and fun to see all the things you try. It's definitely given me confidence to try slot of new things myself. Hope you'll be fully recovered quicklt from whatever pesky illness you have at the moment so that you can get all the things you need to get done in time! This has turned into one of my all time favourite YT channels, little did I know I was in for a double refit of the same boat but I do think all the changes you've made are for the better. Good luck with the rest!
You can put a heat shield on that one dock line to keep it from burning or add a small piece of chain going down the area where the exhaust is and then clip on the dock line.
Last Sunday not finding your video I have been worried about you but seeing you today has made my day knowing that you didn't get covid 19 take care hope you are feeling better soon
Very helpful. Going to use on my boat.
Thanks, stay healthy my friend. I agree that the places the fans are will need intake vents.
You are so good at doing 10 things at the same time. I'm don't know how you do it but it's impressive.
I was watching this thinking the video quality was great. Then I realised it’s the lighting. You definitely nailed it with the colour temp and spread of lights.
We missed you!
Welcome back Sunday friend sorry you haven’t felt well
Great to see you back, hope for full recovery as soon as possible.
Lighting is spot on, provides great video quality!
Considering the exhaust I would go with the aft position in order to avoid the dock line, but (if possible) place it under the chainplate so that is as far from the ladder also...
I vote for through the stern. Chances are you won't be running the boiler unit while using the swim ladder in the summer. Get well soon.
Cheers,
Jay
