I am trying to determine whether I should implement a second water
heater on my Lagoon 400
and how it should be done. I am looking for members with relevant experience or with opinions.
As part of the standard equipment
the boat came with a Quick Boiler B3 water
heater. This provides hot water when the starboard engine
has been used or when connected to shore power
. It works fine and we have had lots of hot showers.
As an extra I had a Combi D6 diesel
heater installed. This is designed to be both an air heater and a water heater with its own tank. Only the air heating
function was installed and it works fine. We survived winter in La Rochelle with a sufficiently warm saloon
. The French technician advised against installing the water heating
function. He thought I would be disappointed. Unfortunately I was never able to find out why he believed this.
We do not have a genset and I would like to continue this way.
So far we have been at marinas
with shore power
and most of the water heating has been from the shore power. This is about to change to spending a lot more time at anchor
. So I am reconsidering how we will get hot water. Shore power will no longer be available and I would like to avoid starting the engine
just to make hot water. I am considering installing the hot water function of the Combi D6 diesel
heater. This leads to my questions:
1. 1. Should I install the water heating function on the Combi D6?
Does anyone have experience with this in a marine environment
? I note that the unit was originally built for the RV market. Particularly has anyone installed it as a second heater? Does anyone know why my French installation
technician might have had reservations about its performance as a water heater?
2. 2. How should the installation be done?
It is not a straight procedure from the installation instructions. There needs to be consideration the installation of the existing Quick water heater. There needs to be a way to be able to switch between the 2 heaters. Any experience with this?
