Hot water tank blowing hoses off - Maxum Boat Owners Club

Free_spirit · 06-05-2015, 10:29 PM

Hi all. Very new to boating and have the SCR 2400 (1998). It has a Hotpot hot water storage tank. Whenever I fill the water tank and heat the water it seems to blow the hose off the cylinder, filling the engine compartment with the content of the tank.

The water also seems to be 'boiling hot'. The hose when I tighten it using the jubilee clip I can't remove with my hand. So it seems to be as tight as I can make it but still it blows off.

Any suggestions would be appreciated.

Not sure where it is located but you may need to adjust or replace the thermostat. The water should not be boiling hot..

+1 thermostat is either set to high or stuck on.

Funny the high pressure valve is not opening to release pressure as it should. You may want to replace it.

Spam or a guy telling us about his male issues.

Spam.

It's happening a lot more since the site was acquired by the new owners. Either more exposure or less controls.

Honestly, it's about the same. Take it from the person that deletes this stuff. About the only difference I can see is the current version seems to leave the post, where previously we could delete it completely.

Now hijacking is another story altogether, as is whining about management. LOL!!!

Back to the OP's issue.

Welcome aboard Free_Spirit!!

I had never heard of a HotStot hotwater storage tank. To be honest, I did find the company, but couldn't find a product under 80 gallons. What is the size and model? Everyhing I have seen looks like residential and commercial use. How is it connected to the system?

Hotpot Twin Coil Calorifier (Universal Mount / 40 Litres)Part No. 520340
In stock .

Is it one of these?

It is regulated by the engine thermostat, so check your engine cooling system. the thermostat can get frozen/rusted, or may be changed to a high performance high temp.

The hotpot expects the engine water to be below 85c degs. If it is above this something will blow.
