Re: Removing Hot Water Heater

The extra coolant tank (actually a header tank) in the locker is only there because you have the water heater. The fill point and a reservoir must be the highest point in the system. When the water heater is added, the heat exchanger in the heater is higher than the engine water jacket, hence the added header tank. If you remove the heater you can revert to using the tank on the engine. Just make sure you put the right pressure cap on the engine tank. Currently the one on the engine either has no pressure release or a higher value than the one on the tank in the locker. Hence the one in the locker relieves pressure first and vents air. If the one on the engine vents first it release coolant as it is under water. When the heater/tank is removed, put the cap from the header tank on the engine.
It is in principle a very simple job, but it's a boat so it won't be simple at all.
Good luck.
Paul

expansion tank

I need to flush my coolant. I don't have a second tank above the heater so not sure how to purge the system. My wife really likes the hot water so for now ill keep it. Suboptimal above the batteries and with echo charger and Genasun in there too.

Re: Removing Hot Water Heater

Cheoah,

Do you have a t-fitting with a **** for bleeding in the coolant line to the water heater? Its installed on my PSC34 in the port locker close to the water heater. I have a surge tank but I could imagine to purge the water heater through this set up.

Cheoah,
Big brother is watching me. The **** in the last post is a Charlie Oscar Charlie Kilo aka as a technical term for an opening/closing armature.

Re: Removing Hot Water Heater

RainDog,
We recently removed our water heater as well and it was pretty straight forward as Dave says. I found a metric plug at McMaster-Carr for one port and then bought a temp sending unit at Catalinadirect.com. Catalina used the same 3jh2e on their boats and they sell a metric threaded temp sending unit that works with a Teleflex temp gauge.
Since we had to drain the system we pulled the heat exchanger and cleaned out the crud buildup, changed out most of water hoses, and replaced the exhaust riser and elbow. Maybe it is just me, but I'd swear that the water flow increased dramatically exiting the exhaust.
Incidentally, the space created from removing the hot water heater allowed me to install 4 Trojan T105s - I had to lengthen the existing battery compartment opening 2 inches.

Would love to see some pictures of your battery install if you have any. That is next on our list once the HWH is gone.

Re: Removing Hot Water Heater

RainDog,
Here are a couple of photos before I finished routing and cleaning up the wire runs.
I have more detail on our website (still under construction) at Electrical System - Cruising Indigo

Re: Removing Hot Water Heater

Wow. Great write up. Thanks for taking the time to do this. I am going to pretty much copy exactly what you did. Exactly what I have been looking for. Where did you install your charger? I hate to put it with the batteries or the engine, but also hate my other options. Still trying to decide.
