Answer the following statement(s) true (T) or false (F)
1. Although space heating is the primary load, hydronic systems can also provide heat to other auxiliary loads. Examples include domestic water heating, garage heating, pool or spa heating, and snow melting. 2. Domestic hot water (DHW) is by far the most common auxiliary load to be combined with hydronic space heating. 3. An indirect water heater is an insulated storage tank that produces its own heat, as does a typical direct-fired water heater. 4. For garage heating, radiant slab heating is the least efficient in situations where a relatively constant temperature will be maintained. 5. The author's position is that antifreeze must be used in all hydronic garage heating applications.
