I'm sure that most of you have experienced the death of your original waer heater. Mine is in itsfinal stages now. The only problem is how do I remove the dead carcass without distroying the cockpit or interior. Also, what is your choice for a replacement?

Cut it up!
Dave,I had the same problem, in the process of removing mine now. Check the "Forum Archives", most everybody else has sawed it up to remove it , then found a replacement to fit back in w/o a hassle, hope this helps let me know how it works out , and what you used for a replacement, later Cecil

If you can't get one out......
Cecil; If you cannot get one out without cutting it up how are you going to get the new one in? There has got to be some of those tried and true Cherubini owners that have done this without cutting the water heater up to remove it. Most of the water heaters are about 13-14" wide.

An idea or two.
You may want to post this item on the "Ask Any Sailor" forum in case some H30 owners don't read this forum. I have noticed that some owners have installed smaller water heaters in more convenient places, like under the sink. But these are usually 110V only or propane or diesel only, not also heated from the engine. Don't know anything about the H30 but on my H37C the water is heated both with 110 and the engine.

Heater removal and replacement
Dave, Here's what I did: went to a tool rental place, rented a reciprocating hacksaw for $25. A couple of hours later, the old iron beast was cut up and out of the boat. Ariston makes a nifty little 110v heater that fits in nicely on the forward bulkhead of the starboard cockpit locker. I bought mine from Defender for about $150. That's all you need for that boat since you can't use a engine heat exchanger (since the engine is raw-water cooled). John Reid Cheese 'n Crackers john.patti.reid@juno.com

Tankless Hot Water System, Inc.
Dave, this may be the answer to our problem, haven`t priced them yet.Check them out at www.webmerchants.com/tankless/ Their e-mail address is ThwsInc@ix.netcom.com I saw these or something similar featured on "This Old House", don`t know why they couldn`t be used in a marine application.Later Cecil

Tankless solution.
Don't think this will work but would like some other opinions. The only 110V option only provides 3KW. If you study the chart of "temperature increase" you get +20 at a 1.0 gpm flow. And only +10 at a 2.0 gpm flow. FLOW RATE (GPM) .5 .75 1.0 1.5 2.0 3.0 kw | 41 27 20 13 10 That's not going to be a very pleasant shower. And the dishes will not come clean. Then there is the issue of no hot water from the engine so you would need an inverter and lots of amp/hours. What am I missing here?

Ed-One Cecil-0 Thanks Ed
Thanks Ed, didn`t read the fine print,checked and found out a home shower head flows about 2.0gpm, I was unable to find out what the hand held units flow(pg 476&477 of Boatus catalog 2000), this is what my boat is equipted with.The heater I`m removing doesn`t have eng assisted hot water.Any thoughts on solar assist? Also thoughts about the shower draining into the bilge? I have the eng. out of my boat,I believe I can remove & replace the water heater if I remove the fuel tank(a task that must be done), cutting up the old one seemed the simplest thing to do after reading the past forums on the subject.Thanks again for the insight, later Cecil

For what it is worth...
On my H 33, I replaced the old tank with a nifty little one from Rheem, capacity of nine liters (2 1/3 gals). It has a 1500 watt element, normal for somewhat larger heaters, so it heats more quickly. Since my engine is raw water cooled, I had no need for a heat exchanger. I also have a large battery banks, so I installed an inverter. It is ideal for warming water at the end of the day, using the inverter while the engine is running to either dock or anchor. It will also heat water without the engine running, but will deplete the battery banks by about 10%, which can be recharged the next morning while getting underway. In practice, the charging comes from a combination of running the engine (and inverter) while anchoring and recharging the balance while upping anchor. Plus, if I happen to be motoring, I will just heat the water then and it stays warm. With a little thought and management, it works well.
