some like it hot...

The heat pump in our house died. The compressor outside hums but doesn't spin up. It's either siezed or needs a new starting capacitor.

Aquarium was hovering around 88 degrees last night. This is verrry bad. I unscrewed all the light bulbs, so that when they come on only the fans run to cool the water off via evaporative cooling.

Unfortunately the house is pretty humid inside. I opened all the windows and that helped considerably. Thankfully it's not 110 degrees outside.

If we throw parts at this thing, it's definitely time to upgrade it. I'm going to tear into the furnace tonight and find out what size electric blower motor it is, frame 48, frame 52, etc .. and see about upgrading it at the same time to something that is stronger but consumes less current (higher efficiency), and hopefully to gain some RPM to increase the overall CFM output.

seems the aquarium needs some sort of temp control system...
may be some peltiers (so can heat and cool by just inverting polarity) or some gadget like so.
good luck with the heat pump.

The aquarium is a bottomless pit of money sitting on the edge of disaster that requires more money to fix any given problem, at all times.

When things in the tank die, it can cause a snowball effect where everything cascade fails, and in the span of a few days everything in the whole tank can die.

So it has redundant heaters because they're not too expensive and if one dies the other can pick up the slack.

Cooling the water will take a chiller unit that's at least $500. Not bothered with one yet since it's normally cool enough in the basement even during the hottest months, as the A/C system of the house undercools the top floor and overcools the basement due to the nature of heat rising.

A battery power backup system is also in need. Right now a power outage of more than about 4 hours spells death to everything .. we have no UPS system for it. A normal UPS system has a modified sinewave output that cannot drive magnetically actuated water pumps. The pumps sieze, overheat, and can even catch on fire. So we need one of those super expensive "True Sinewave" output UPS systems, and it has to handle around 1200 watts. Then we need a bank of 12 volt deep cycle batteries to handle the current draw for however long the power is out. It'll be about 1 D4 RV battery per 2 hours of run time. Total cost would be anywhere from $1500 to $2000, as I've priced things out.

So a chiller to account for when the a/c system fails, and a UPS to account for when the power fails .. neither of which normally occur ... disaster planning sucks when failing to plan for it creates a disaster in it of itself.

As much as that really, really sucks, I have to ask...

Did anyone else not understand that last paragraph at all?

Basically I'll make it blow more air and suck less energy doing it.

There! Words that can be understood by my sleep deprived brain.
