In the construction market, the one most important characteristic of phase change material is the operating temperature. It will not do to require ino rdinate amounts of insulation to maintain the phase state. Volume they have plenty of, so that usually is not a real big factor. Of course toxicity an d handling/ storage hazards are big.

he one I have uses direct ground to refrigerant exchange, there is no inter mediate efficiency killing glycol loop. The ground heat exchangers are simp le single loops of copper pipe (200x the conductivity of polyethylene), one loop per 1/2 ton capacity, loops connect into manifold, manifold to single pipe to ordinary mass market scroll compressor. The loops are inserted int o small boreholes to a 60 ft. depth separated with a 60o offset from horizo ntal making for a compact installation. The copper piping is protected with a continuously brazed sacrificial electrode wire along its axis making for an effective lifetime well in excess of anything considered satisactory. S ince the heat transfer is between thermal sinks effectively at constant tem perature year round and day and night, a characteristic critical to the mec hanical pump technology, efficiency is very high.
I live in mid-Atlantic so forced air through superinsulated flexible ductin g is the best option. It was possible to add in a second heat exchanger for radiant heat distribution through the underside of the flooring, but that would have required an additional 20% capacity in the central unit, more co ntrols and mechanicals, and of course added cost and all for a relatively s hort heating season of maybe 4 months- so I stayed with forced air year rou nd.

You do not need any to know that they used the term universally back when they started doing it. If it is a compound of Sodium then the property they are after is the Sodium component.
Ford makes high end exhaust valves which are filled with actual pure Sodium. They are sealed units. The solar farm I referred to does as well. There are several systems which do not and use variations on the theme essentially cashing in on the thermal properties of the Sodium component. Salts of the Earth, as it were.
Just go to Home Depot and buy a box of TSP. In your case, you might have to smuggle it in from Nevada, though.
...or Canuckistan.

Home Depot sells TSP in the paint section here in Sacramento.

LOL- that's what you get for eating too much! And there's no law says you can't flush once, twice or even thrice during the "major event."
I suppose you could soak the dishes in the sink for a few hours first. Water dissolves all sorts of stuff. It's kind of polar that way :D
What? You don't collect the cold shower water in a bucket before the hot water comes online, then use that water for flushing? :D
Michael
You need to read the fine print on the box, if you have not already done so. My son lives in New York State. He has a box from Home Depot which is clearly labelled TSP. But the fine print says it is Calcium Carbonate, a TSP substitute. Selling TSP is against the law in New York.

Well wow, "Supplier Trade Secret" for chemical name, huh.
Thanks. I never would have suspected...
Michael
You mean eating at all.
But it wastes water. These low-flow toilets clog easily and then tend to overflow, so people flush often, which wastes the water they were supposed to save. Some sort of compromise, like 2.5 gpf, would have made more sense. But government make sense? Rarely.

Hey, maybe we could wash them by hand!
No, we water plants with that.
A grey water system, shower runoff into the garden, would be great, but that would be a nightmare to install.

You might try a different make, something like this in 1.28gpf:
it's critical to keep that siphon jet channel clean, it concentrates the water to push the waste into the trap, use a stiff cylindrical brush:
Not as sanitary. The heat from the dishwasher sanitizes better, unless you have some quaternary ammonium handy for sanitizing after rinsing? :)
Wow, you have that many plants? :) :) :)
Yeah it would...
Michael
Well, toilets aren't something that you try like pens.
I prefer appliances that just work.

LOL at Ford. Sodium-filled exhaust valves were standard equipment at Alfa Romeo in the 1960s. So was all-alloy engines, twenty years before Ford started trumpeting "Alloy head" on badges on their cars. It's no wonder that the USA doesn't have a car manufacturing industry any more. You kept making boring ugly 1930's vintage tractors too long.

That one is highly rated, not expensive, maybe $200 at HD, installs without tools. The only spec you need to know is whether your drain is 10" or 12" from the wall, get the corresponding model. It comes as a complete kit, inc ludes gasket, and you don't need any tools. Just get white, any other color can double the price, can't believe the fools who fall into that designer bathroom crap.
