Espar

Here is the complete manual. I had one for 12 years and never had to do any maintenance. In that time, my total hours would approximate the use a burner would get in a year or two of full time use. However, the sitting time is probably more damaging than running time, but I had no problems, none the less.

Espar D5 Heater Question

We have a 2009 Espar D5 Heater and need to find out how to reset it. There is not a reset button on the heater or the control box that is installed near the heater. I have heard that there is a way to reset the fault que by jumping across two pins on the main wiring harness connector. do you happen to know this procedure? do you know the wire colors/purpose, in case the connector is different? I have tried grounding the "blue & white" "diagnostics lead"..but I am concerned about connecting it to the hot lead for obvious reasons.

Thanks, Jay

Jay,

Have you tried shutting off the power supply/circuit breaker for several minutes?
I'm not sure if it would help, but it might.

I've supervised installation on new boats and tracked warranty, personally I would choose the Webasto, but the Espar is good too.

Caveat: Very limited time using a diesel furnace for cabin heating

I chartered a Nordic Tug 32 out of Juneau two years ago. The boat had a diesel furnace, but it also a "bus heater" where generator or cooling water">engine cooling water would be used to provide cabin heat. The hot water heater was powered by 110V via the generator, or main engine heat.

I found the diesel furnace to be LOUD in this installation, as well as on another I heard on a marine patrol boat. The furnace was much louder than the generator. The generator made a soft low rumble we could barely discern, while the furnace roared at about the same volume and frequencies as speech, obliterating the ability to comfortably carry on a conversation.

Since we needed the generator from time to time anyway (110V service, microwave, hot water, recharge the laptop, cameras, and phones, ...) we found we generally just turned on the generator when we wanted to warm the boat up, even if just for 10 to 30 minutes at a time.

I did see many people with diesel furnaces up there, including on outboard powered fishing boats that had special diesel installations just for the diesel furnaces. So they do have quite a following in the field.

I was just surprised that using the generator to heat the boat was a more pleasant option.

hmmm.....I found the Webasto units to be nearly un noticeable in 24-32 ft aluminum boats.. certainly nothing even near to a gen set... most of these were installed under a setee.... in a cabin 8-10 ft long... I do like the water/heater core units though. However they will only heat if you want to run the engine or gen set....

I have installed and used two D5s.

Good units, I wouldnt touch the ESPAR water heater units use webasto. But the Espar airtronic units are good.

If you are travelling away from civilisation , I would bring a spare control box, spare electric pump and spare glow plug.

They are actually simple enough units to take apart as well.

Generally the like being used and most problems come from underuse.

The electric pump has a tiny ( very tiny) integrated filter in the input of the pump, Its like a tiny sowing thimble. It can get blocked. I have the prefilter unit unit before the pump and mine still blocked.

other then that , if it aint broke dont fix it.

The digital timer module is useful to have ( you can get then on ebay) as its displays the faults codes and diagnostics.

NOte the modern D5 units do not have a lock out system, and hence dont need to be reset, like the hydronic units. This change came in around 2008. ( Eperspacher confirmed this).
