PLEASE read my original post!
The point of constant circulation is that you only have one to a few circulators running. the boiler is not idling and then a heat call makes it burn hotter than hell. It keeps things relatively constant, and the TRV's modulate the continuous flow through the radiators so that they maintain a constant temp. Ideally it is never dumping cold water back into the boiler, you never have temperature fluctuations in the house. This should save fuel.
When you look at having a dozen circulators in your home that will be running at least the equivalent of 2 hours a day, if not more, you break even or save on electricity.
If I'm wrong someone with experience with this type of system please tell me?
Frustrated? Don't be.
The reason you are getting advice about other products and solutions is because your requirements and conditions are changing, for which there are better solutions. You don't have to follow those suggestions, but it would be wise to investigate them and then see the reasons they are "better" and the compromises you may get by not using them.
If you can then accept those compromises, not only will you be going in with your eyes open, but you also have the opportunity to mitigate them. Heck, if it costs you 10% more fuel and you can live with that, it's a WIN
In your other thread, it looked like you had some good options, then you threw in a "solar only" requirement. Okay, very low power requirements often require performance compromises and sometimes "old style" systems.
In addition, having a "build as you go" system (like many of us), you don't really have the benefit of doing it all at once and creating a fully balanced system- even if you had super-duper-expert help. It will be a moving target. Maybe you're okay with that, but folks here are trying to give you a heads up about it so you're not frustrated down the road.
Personally, once you went with the uber-low-power requirements of solar and only one or two circulators, I took a step back to let some others with more experience in that area step forward. And they did
Doesn't mean I don't agree or disagree, but we try to be pretty "responsible" when it comes to heating recommendations. We all know your home, your family, possibly even your life is on the line when it comes to HVAC systems and we're a pretty cautious bunch there- as you should expect. Anyone who isn't really shouldn't be heeded.
Here's a suggestion that might help.
Now that you have gotten some really good design tips, cautions, suggestions, etc with your initial scatter-shot, take that info and refine your goals and system. Separate the requirements from the wants.
Part of that should include a HeatLoad/HeatLoss calculation, and I'd suggest the Taco software that does a decent job of calculating flows, design temp requirements, etc. It takes some time, but is far cheaper/faster than experimenting physically, then finding out you have a critical problem somewhere.
Hopefully this helps!
