Happy new year everyone!
I would very much like to hear from sailors with first hand experience with Glembring diesel
Until a couple of weeks ago, I was determined to order a Refleks diesel heater
manufactured in Denmark
. Even though I hate making irreversible alterations to the boat
, I have come to the conclusion I simply need more heat on board to keep on sailing comfortably during the winter months. The Refleks heaters are installed in countless fishing
boats, and have proven to be extremely reliable, capable of 24/7 operation during the harsh Scandinavian winters. My mind was initially set on the 2000K (4,2 kw) or the 60M (5,8 kw model) The former, being a convection model, would hopefully distribute the heat more efficiently than the latter, being a regular model relying primarily on radiant heat. Hopefully the convection effect might compensate for the 28% lower output. Both of these models can be equipped with a cook top and a tiny round window so I can see the flame going on in there. No matter which heater
l will buy, I´ll probably add an EcoFan or something similar to facilitate air circulation. Unfortunately, I´m not able to install water
circulating radiators to distribute the heat. Simply not an option given the interior
of my boat
In the process of researching, I came across some pictures of the Swedish made Glembring heaters. With the exception of not having a convection model listed on their website, the heaters seem to be pretty much equal to the Danish counterparts, both regarding technology, fuel consumption
and physical dimensions. However, the swedes can be delivered with a rather large rectangular window, which I find extremely aesthetically pleasing. Much of my (tentative) thinking has taken place in front of a fireplace, as I find the flames very cozy and relaxing. Therefore, I´m most tempted to install a Glembring heater, rather than the Refleks. The Glembring IG 92/7 (4 kw) or IG 92/8 (8kw) models are the only options I guess, but assuming all models are created equal (only different sizes), I very much would appreciate information regarding any Glembring heaters, no matter which model you are familiar with!
I am primarily interested in information regarding reliability
. How much heel will the Glembrings tolerate? Will the regulator
turn off reliable in case of overheating
, excessive heel etc? Will they tolerate running on low effect without clogging or leaving the cabin
smelling diesel? The latter is very important if I should pull the trigger for the 8 kw IG 92/8 model, as I suspect it might be a tad too big for daily use. Nonetheless, the hole I have to cut in the deck
, the extra diesel tanks
(both a big one for fuel
supply and a smaller expansion tank mounted below the regulator
in case of an overflow), the pipes and shielding needed, and the interior
alteration to my salon
will be the same no matter which model I choose, so a heater with some extra output certainly is no deal breaker, as long as it runs clean on low effect as well..
I know quality of combustion and risk of backfire will be related to good draft
, so while not sailing, I will rig a tall insulated and easily detachable flue pipe on deck
. I´m not planning on using the heater while under way, at least not sailing upwind.
The Glembring factory is located in Gothenburg, which is a three hour drive/ a long weekend sail from here, so an added bonus with the swedish heater is I could easily go there to pick the brains of the manufacturer. Needless to say, I don´t cut 5” holes in the deck of my beloved boat on a regular basis, so this is a “ask five times, cut once” situation.
By the way: I have two Webastos on board (AirTop 3500 and 5000) so there´s no need to recommend forced air heaters as an alternative. My Webastos work
very well for heating
in an instant, but I long for a reliable heat source that doesn´t use electricity, that can be used 24/7 without annual labor demanding/ expensive rebuilding or replacement. Also, the added bonus of putting the kettle on top of the heater in case I run out of propane
in priceless. I´m no good without my coffee..
I don´t post links to any products, as I´m not here to promote neither the Refleks nor the Glembring heaters. I just want you to tell me the juicy details I won´t hear from the people selling them..
So, I already know the refleks has an excellent reputation.
My hope with this thread is to learn how the Glembring performes in comparison.
How they compare pricewice is not a factor in this equation. Safety
, fuel consumption
, comfort and aesthetics is all that matters.
Thanks in advance, your first hand experience is highly appreciated!
