I have one like the heater in the third pic (the green dash). That one has a round core. I also have the one that is shown at the end in varios stages of ressurection. They both have good cores and good tins. What are the upsides and downsides of each? It looks like one is always circulating and the other deluxe has a thermostatic plumbing bypass switch. What is deluxe about the deluxe? Does one give moor foot room? Like maybe my dog won't bonk his head on the smaller one?? What are the correct color codes for these? Hey, thats a good segway to my other thread idea.
