Check your fuel regulator, sounds like not enough pressure is present to open the injectors.

The emergency heat will not turn on in my system. I also noticed the emergency heat light does not turn illuminate on the Honeywell HZ322 TrueZone Panel even if the emergency heat button is pressed. The...

Yes, I believe you are correct concerning the circuit panel.

Regarding your heat pump not keeping up ...depending on what part of the country you live in, heat pumps are not the best thing to heat with. As you probably already know, once it reaches 32 degrees outside, the heat pump stops working and the electric furnace or heat strips come on to supply warm air. Frankly, when that happens, it's like turning on your kitchen toaster and blowing air across it with an electric fan. Doesn't sound to efficient does it. Plus, your electric meter is spinning like crazy and the power company is falling in love with you.

In my area (Virginia) most new home construction is now using what's called a dual fuel system. It's a heat pump, but it has a gas furnace backup for when it reaches 35 degrees outdoors. It's very, very efficient and a very comfortable heat. The gas furnace can run on either Natural Gas or Propane Gas.
In most cases this can be added to an existing heat pump system. The only thing necessary is the Gas Furnace, since you already have a heat pump and all the duct work. Could probably be added for a whole lot less than you''d expect.

The other option is to add a vent-free gas fireplace or vent-free gas logs, if you have an existing solid fuel burning fireplace. They are great for zone heating and/or supplemental heating. Plus, if you have a power outage in the middle of the winter, they'll still work, as they don't require any electricity.

I didn't mean to run own, but I hope all this helps you solve your heating problem.
Please let me know.

I plug my reddy heater in and it comes on then shuts back off. What is the problem?

Try cleaning the flame sensor. Remove the top of the heater. The flame sensor is a black rubber boot close to the fuel nozzle. Pull is out of it's holder and use a soft cloth or cotton swab to reach into the openning and clean the eye. While you have the top off, watch out for the fan and turn the heater on and use a flashlight to look for fuel spraying from the fuel nozzle into the burn and make sure the igniter is working. I don't know which type you have but it may be the spark plug type or a hot surface igniter which should just glow red hot. Let me know what you find.

Unit sprays constantly.

Mine did the same thing. There is a valve that controls the spray that seems to work its way loose from its designated spot. This in turn depresses the actuator on the valve making it spray constantly. The valve is located where the upolstry cleaner cleaning solution port is. Disassemble the upright portion of the vacuum and make sure the valve gets pushed back into its place. I was able to use a ziptie to hold it securely after correcting its position. Use the two holes in the upright portion of the vacuum directly behind the valve to ziptie the valve in place securely.

Called Beckett at 1-800-OIL-BURN and explained the problem. They told me that the solenoid on the oil pump (Clean Cut) was the cause. I purchased a new pump for $50 at the local plumbing supply and installed it. Problem solved.

I have a bosch 24cdi rsf combination boiler reaching 3 bar pressure and blowing off through release valve. any suggestions.

if this occurs when the unit is in use for only hot water, there will be an internal leak in the secobndary heat exchanger, you will have to replace it. check first that the charging link has been removed when testing to ensure it is not passing.
if it happens when the heating is switched on then check the presure in the expansion vessel ( dump all presure from system and use a car foot pump with a gauge there should be 1 bar presure) that is the big red thing behind the pump, if water comes out of the test valve on the front of it when you try to test it or it wont hold the presure you will have to replace it (a nasty job you have to strip half the boiler) if you can pump it up make sure you release the presure in the system as you pump it or you will get a false reading
