Some of the more advanced thermostats will track how often they are running. I have a Filtrete Wifi-Enabled Progammable Thermostat. It gives you a per-day total of how often the heat and A/C are run. You can also download an hour-by-hour export of the usage in CSV format. I am in no way affiliated with this company. It is simply a product I have ...

I have an ancient oil-fired steam boiler with a "tankless" hot water heater. I built an Arduino-based board that connects in parallel to the thermostat wires at the furnace. It uses a MID400 AC optocoupler to detect when the thermostat is calling for heat (24VAC when not calling for heat, 0VAC when it is), and then sends that to a computer via an XBee ...

While this won't specifically isolate your furnace from the rest of your energy usage, I'd recommend getting a Blue Line PowerCost Monitor (or the Black & Decker branded version, which is cheaper) their WiFi Gateway, and a free Microsoft Hohm account. Current Amazon links and prices: Black & Decker EM100B Energy Saver Series Power Monitor, $43.99 ...

Since hot rises, upper stories will tend to be warmer unless the design of your air conditioning system properly compensates for it. An energy audit, as mentioned in the comments by @mikes will tell you if you have any reasons for heat gain that may be correctable. Assuming you have a single thermostat that controls a unit that supplies both levels, here ...

When electrical appliances talk about Amperes it usually means how much max POWER it can OUTPUT or how much max POWER it can MEASURE In your case, the spec actually means not to exceed the 16A limit. So if you are monitoring a 10A socket that is well under the spec. So you will be fine. As long as you do not exceed the 16A monitoring device limit you ...

You could mount a wind speed logger in your ductwork or in front of your air intake vent. It should have negligible drag effects on airflow through the system. I'm not sure how accurate the results would be though. The air movement from your furnace running is going to be a lot less than outside wind levels, which is what most wind speed loggers are actually ...

As you'd need to maintain those $370/year savings for 54 years to gain any return on your investment you do need to consider other factors. As you point out - you need to work out if it significantly increase the value of your home. Another side to this though is would it make your house significantly easier to sell? In a buyers market if you can offer ...

Its a pricey solution, but get a Nest thermostat. It will track that and send you an email every month on how much the system has run so you can track it and the costs associated. I just installed it, took less than 20 minutes. The feature I really like is that the system is remotely accessible. I travel extensively for work and will put it in away mode ...

Jay, if you need to monitor just the furnace (what kind of furnace), a very simple Amprobe chart recorder will do the job by monitoring the electrical inputs to the burner or pumps without any invasive wiring or computer interface. Old fashioned, but used in industrial applications for decades.

There is no real right answer here. Obviously if you just crunch the numbers it is a very long ROI. Personally if it were my house and I had the budget and inclination to do something, I would start with projects that are currently subsidized by the government or energy company. I would also consider doing any really cheap but effective (according to the ...
