One of the heat systems in my house is electric powered hydronic heat.
I'm using a water heater, which is sufficient for my needs. Time-of-use
electricity makes it cheaper than propane, nights and weekends.
I'd like to do something a bit more sophisticated than my current
control system, which is a day/hour timer switch. Can anyone suggest
something which ideally would be:
1. Computer controlled (PC is OK, others are OK too)
2. Capable of driving a 30A 240VAC relay
3. Capable of taking temperature readings from several inputs
to determine if the relay needs to be on or off
4. Reasonable cost
Basically, a smart controller that knows about time and return water
temperature, and turns on the heat when it's got access to cheap
electricity and when the floor is cool enough to need it.
Suggestions of vendors, or specific products, or even homebrew solutions
are most welcome.
