Inhibited propylene glycol if you are using antifreeze instead of water, But I do not understand why unless it is a vacation home or something along that line.
My heating system currently has antifreeze in it. The system is completely isolated from the house water system. A small RV water pump is used to fill the system and pressurize properly. I do not know the type of antifreeze used in the system. With complete isolation, automotive should be acceptable. I am investigating RV antifreeze as well. Automotive antifreeze is toxic. There must be no connection between the heating system and the potable water systems. Isolation valves are not acceptable.The usual FHW heating in a home or other building is connected to the water (drinking water) supply with a pressure valve at the boiler.Automotive antifreeze is deadly and can cause blindness even in small amounts.There is a special antifreeze (non toxic) for use in heating systems where a backup/mix/crossover with the drinking water could occur.You could also burn out your circulation pump by using the wrong antifreeze, which is very expensive to replace.

In order to properly install central air and heating systems into a home, one should have general experience with home improvement and maintenance, along with training in both electrical installation and plumbing.
Most home systems do offer both heating and cooling in one. Some of the older systems have separate heating and cooling. Heat pumps provide both heating and cooling. Other types of systems do not. However Heat Pumps can only efficiently heat a home if it's not excessively cold and therefore you usually need a supplementary heating system.
The evironmental standards for home heating systems are to make sure that a homeowner will purchase and have installed the appropriate heater. The heater should also be very effecient with a high AFUE rating. A good AFUE rating would be 95.

Antifreeze would be required if the home is not adequately insulated or there are spaces where cold air has access to the pipes such as holes in the walls or floors. Also, if a wood stove is operating, the rooms' thermostat will not call for heat so the pipes can freeze up and burst when thawing out. Should the home be used infrequently during winter months, it is not a bad idea to have antifreeze put in the heating system unless you are prepared to make sure the home is heated and have a plan in place in case power is lost.
