I definitely can find more efficiency by adjusting the warm weather shut off that dictates when the electric boiler can turn on. I can also get thermostats that would interact with the mini splits instead of using the remotes. I have 2 multi-zone units so that’s 8 heads so a lot of thermostats...

I’m back to report everything has been working as intended and I actually reduced my year over year electric bill for February! Last year I ran exclusively on the mini splits as my oil burner was broken. It has been warmer this year but the combination of the electric boiler for the hydronic...

Great dialogue here everyone. As I mentioned the electric boiler is installed and operational. I have it linked to the Taco outdoor reset control which I can set for an electric boiler’s usage parameters (such as no minimum supply temp) and crucially I set the Warm Weather Shut Down to the mid...

Long Island is expensive. If I could, I’d live where I could not see my neighbors and had plenty of space for projects, garages, and hangars. I think that a dump load controller is a great idea. I spent a lot of time looking into DC heating elements and rolling my own. But I work a lot so my...

It is installed and operational. Just started to get colder here so it will be a little while before I understand my usage. It’s an Argo 16kw electric boiler AT164410C.

I saw one in the background of Will’s latest video but I’m surprised how silent this forum has been on this new version. Looks great.

The electric boiler is a resistive heating element with 4 x 4kw elements which are electronically controlled to stage usage but can also be individually turned off. That gives me options to cap peak usage. I’m also wiring this to the outdoor reset control which should keep boiler temps low and...

Okay, I guess I need to reply twice since your edit. As I've explained ad infinitum, I have used my multi-zone mini splits to heat and cool my home for the last 2 years with great success. I have a indoor unit in every room. The oil burner was part of the previous primary heating system. It was...

The boiler replacement is in progress this week actually. I went with the electric boiler and redesigned my plumbing around the boiler into primary/secondary hydronic loops. I also upgraded my circulators to delta T models (no zone valves, each zone has a circulator as an independent pump)...

I'll see you at the weekly support group meeting, I'll bring the cookies. Initially I was in a pickle to make a decision quickly for this winter as my heat pumps were not rated below 14 degrees F. However I found LG makes a retrofit kit that allows operation down to 0F. I installed those and...

I’ll be watching this thread with interest. At present I’m planning on a parallel Growatt setup for 240v loads only. Would be a shame not to be able to use 120v in the future. Also, the Growatt’s debatable UL compliant, certified or listed rating could also write my whole project off.

Thank you for your reply, you're not late since I haven't started! I'm am really trying to stick with the hydronic system since I put so much effort into re-zoning it and the baseboards are also all new. The heat also feels nicer than the mini splits can manage at lower temps (although my...

Thanks to everyone who has read and/or replied as I went overboard explaining at the onset. The enthusiasm behind my curiosity did not match my subject matter knowledge in order to pose an accurate question at the start. Maybe I can do better now. I was inspired by installations in which people...

Appreciate the benefit of other's experience here, for certain. Trying to avoid the buy now, figure out later chaos.

I've been looking for a solar hot water heater with AC assist, there's the Rheem units, but I believe they are targeted for domestic hot water. I could do air to water heat pump as I mentioned but then it mimics the efficiency profile of my existing air to air heat pumps which leaves a gap in...
