120V HPWH #134

Open jmaguire1 opened 1 month ago

jmaguire1 commented 1 month ago

Add a 120V HPWH into OCHRE, based on the model in OS-HPMXL. This model is based on the Rheem, shared circuit product. I can potentially also add the dedicated circuit version (higher power, but requires an open available 15A circuit). We can also allow backup elements like AO Smith includes.

This also includes adding the ability to model a tempering valve. These products have an integrated tempering valve, so you can overheat the tank to increase the stored energy to compensate for the lower heating rate.

Not all of this is supported in HPXML yet, but that's coming soon. I want to wait to merge this in until those changes happen so that we can properly support this going forward, rather than just having something triggered by temporary flags.

Fixes #133
