Radiant Zone Addition

It would depend on the boiler equipment you have (especially the aquastat) & the way it is set to operate.

Taco Zone Valves

Grady is correct; Taco's have problems working with some programmable t-stats; if there is an adjustable heat anticipator on the Hunter it has to be set to .9.

Since the 1st floor t-stat is the...

Taco Zone Valve

Try checking the voltages with a voltage tester; if you don't have one, there's an excellent GE unit for $10 at Wal-Mart.

Turn up the T-stat to 80 degrees to close the contacts & clean the...

Frozen Pipe

Deena:

Heating the non-functioning baseboard with an electric heater is a good idea; as the metal is heated, the heat will be transferred to inaccessible parts inside the wall & may be enough to...

Low Pressure

It's best to shut off the electric safety switch at the boiler rather than simply turn down the T-stat; it follows that the procedure should be done with the boiler off.

Low Pressure

The quickest & easiest way to add water would be the same way the service tech did the last time.

Run a garden hose from a convenient faucet to the drain at the bottom of the boiler & make the...

It sounds like you're on the right track with the "backpressure" concept; the hot water "sees" the higher resistance in the zone 1 monoflow circuit & takes the least path of resistance (flowing water...

Balancing Valves

Your strategy of limiting the flow in the short loop to get better flow in the long loop is correct; this is a common problem in hydronics & is done with BALANCING VALVES.
