Or it could be a cold - to warm water heater. Just Kidding around. Fair Winds Eric

Thanks, Eric ... and good point Ken - guess it is a "Hot Water Heater" after all!

Craig...adding as much solar completly changed how we cruised. Before i would run a honda generator as we don't have a onboard diesel one. You really can power the santorin with 100% solar.

We don't have any solar, so the Hot Water Heater heats either from the engine coolant (which may also be a misnomer - "hotant?") or from the genset, which adds a nice electrical load to that.

Craig before you do this read my post about how i make hot water from solar. Not sure how much solar you have on your boat but this is working fine for me for the last 3 weeks.

The Hot Water Heater also is a Cold Water Heater, and maybe just a Water Heater. But after the Hot Water Heater heats up the Cold Water, the Hot Water Heater keeps the Hot Water Hot. Thus, the term "Hot Water Heater". :). You see, most of the time, if left on, the unit will be heating Hot Water (this also implies that there is a Thermostat involved). Only when first powered up will it heat Cold Water.
Just another point of view...... Ken Powers SM2K 262

Spot on, Eric! Perhaps not Oxymoronic but at least redundant. However, the adverts do indeed say "Hot Water Heaters" !
Cheers, Craig

This is one of my favorite expressions—hot water heater---- why would you heat hot water? It’s a water heater. Fair Winds Eric Amel Super Maramu #376

Hi Steve,
Ah, the classic split and expanded heating element on the old orange isotemp ! I've got the same unit and I think I'm on my 4th occurrence of that problem. Once I struggled to fish out broken heating elements but some stayed inside and corroded pinholes in the tank. I finally extracted them and then sealed the the pinholes with JB Weld - I'm thinking that was about 12 years ago and it's still going strong! My thermostats also failed and I got replacements for cheap - they are really a commodity item. Amazing, but it's still going strong. Mine is 110v (on my SN) and Isotemp has long abandoned the product, but I can still google a heating element (it's 1100w versus the original 750W, but no problemo). Will be installing a new one this week, as a matter of fact. I'm now moving the preventive maintenance interval up to about 3 years - just throw out the old element even though it's working. I'll admit this really qualifies me as a CARB (Cheap Ass Rag Bagger) but I'll be dammed if I'll pay stupid expensive for the new unit if I can nurse the old one along with minor effort every few years! Cheers, Craig

Hi Gary,

Hi Stephen,
I have not had that problem (yet) but I am curious about it causing a draw vs. tripping the breaker. AnchorExpress.com has the heating elements and Thermostats although their delivery time is long. I got my new thermostat from eBay, actually but the heating element (plus a spare) is on the way.
Funny to me is that the original Stainless boiler gave zero trouble until it just died, but the new and improved all plastic one seems more prone to faults.
Ah, it's the sailing life for me :)

Good idea. It’s been 5 years since replacement, so would not be surprised if the element is toast.

Hey neighbor- before replacing it I would take the heating element out, clean the contact points and check the wiring connections (assume it's a Basic 40, so pretty easy). You'll see immediately if it can be saved. Mine had a similar symptom.

Steve, I have not experienced that, but wouldn't corrosion on the thermostat contacts result in something similar. I would check the thermostat.

The hot water heater on my SM is working normally except for one detail. Normally, when the heater is heating water it draws a little over 3 amps AC. When the water is hot, it usually draws 0 amps until it goes into a heating cycle again. Now, it seems to always have a background power draw of about .75 amps. What I’m wondering is if this means the heating element is partly degraded, but not to the point of popping the breaker yet. Have any of you experienced this symptom, and should I just changed the element now, or could there be a different problem. I’d much prefer to change the element now than enroute to Alaska in a few weeks, but don’t want to do it at all if that is not the problem. Any thoughts on the subject would be greatly appreciated.
