Hi to all,

Few month after buying my boat in 2015, i had a leakage from the inside part of the water heater.

I bought a new one from isotherm ,the same model -basic 40.
Since then , 3 more boilers were leaking and replaced  under warranty by the factory- very good service, but what can be the reason for the failure of 4 boilers in 5 years?

The pressure in the water system is 1-2.5 bar.
The heater has a security valve that opens in 7 bar.

Anyone experienced this?

Ideas welcome.

Thanks to the great group!
