With the awfully cold weather we had our here this winter, my electrical bills hit the proverbial roof.
I had been using electrical heaters with some propane burners as back ups. A real pain. There's got to be an easier way.
I'm thinking of installing a gas water heater and just recycle the hotwater. This way, the ambient temperatures will be more constant, and the air will not dry up as fast. It was the air dryness that killed off most of my lowlanders this past winter... not the cold.
any hints, or ideas

Depending on the mechanical setup the electronics and associated programming could be complicated. There could be various sensors both analogue (temperature, humidity, light etc.) and digital (valve & vent positions, motor speed, flow rates). Then controllers and start up circuits for the heaters, fans, pumps, stepper motors, etc. However the price of the electronics would be trivial compared to the mechanical components and so it would be better to just buy a commercial controller. You could get fancy and add a little web server for remote access and to send you emails when something happened.
The foam maker is just a small furnace fan. So you would have to run a couple of fan motors and a couple of low pressure pumps for the foam/ cooling water part. It could run off of temp and light sensors, timers. It would be nice to set up a PC control though and have net access.
I haven’t mentioned it yet but I have an older CNC milling machine that I converted over to PC control. The PC runs 3 large stepper motors/controllers. I built the DC power supply rewound a big toroid transformer to get 70v dc, breakout board for the interfacing. It’s a cool bot. I love to watch it. It is very cool. I only wish I had more time to play. I will have to get some picks up in the hobby post I guess.
