Targa 32 - Test Eberspacher D4 Airtronic 4 KW and how quick the temp falls after shutdown of heater

[@johningham4942]

I've noticed that targa boats have a lovely heating system on all of their boats,lars and they heat up very quickly. It's no wonder that Targa are the all year round boats and in most of the seas can they operate while other boats are confined to port.

The defroster on the Targa is the beste I have tested in any boat. It keeps the boat warm when driving. With other boats you usually have to use the diesel heater instead.

In my Targa, I use three different systems to maintain warmth on board: 1. Factory-Installed Electric Heaters: These are placed in both cabins and the engine bay, using shore power. They can keep the moisture away. However, especially in winter, they struggle to keep the interior above freezing if the external temperature drops to -5°C or lower. Unlike Lars, I haven’t added extra insulation. 2. Eberspacher Diesel Heater: This has been good in all conditions. It heats up the boat effectively, though it can take a long time. The remote activation feature is a plus, allowing the boat to be warm upon arrival. 3. Targa’s Built-In Defroster: This system leverages heat from the main engines to warm the boat. It’s quite effective. From my experience, the utility of the electric heaters is debatable. They seem most beneficial when staying overnight on the boat during milder seasons like spring.

Hi, I have the same as you. Targa heater in the engine room and in the aft cabin. But they are only about 300W. When it is -10 - 15 it is not enough. I therefore have 3 more heaters of about 1500W each. They heat up the boat great when I am at shore power. The new insulation mats have helped keep the engine room much warmer than before. Merry Christmas !
