I have very good results with the ISOTherm (ISOTemp SPA) (e.g.: https://www.indelwebastomarine.com/int/isotemp/ ). Very good quality and they are a bit smaller (because they are round, without the box around it). They also come with the temperature regulator.
But this is a different brand, so may not be a good option for you.

It is a 6 gal. Seaward [Whale] unit and only connected to the engine coolant circuit [no A/C on board, just 12 V] Planning to replace it with the same unit as that “should” be the easiest / quickest. Two questions for the group: 1] The heater comes in galvanized steel and white epoxy versions. The latter is more $ but is it worth it from a corrosion or other standpoint? It is not visible so aesthetics are not important. 2] Found both units on Amazon for less than Defender and other distributors. Has anyone bought parts / equipment from Amazon Marine? Usually Amazon delivers when they indicate, but I ordered some ink for a home printer and it still has not been delivered after 8 weeks. Thanks, Brian Ps – Very sad news about Rob. Amazing how a “simple” fall can cause a cascade of events. Not much comfort, but at least it was tangentially boating related…
