Pressure increase

Could be your expansion vessel needs re pressurising, or it has failed, finally there could be a hole in your heat exchanger, whatever you need a GasSafe engineer to look at it.

How do I connect the two thermostat wires from a Honeywell R8184G4009 to a programable thermostat. My old thermostat is not marked.

On the Protectorelay Oil Burner Control R8184G4009, you connect the two thermostat wires @ "T" and the other "T". On the ACE Smart Temp Universal programable therostat, connect one wire to "Rh" and the other wire to " "W". Be careful if you are using this thermostat for A/C. In that case, make sure there is no jumper between "Rh" to "Rc".

Cannot light pilot on 4 year old heater rheem tells me part not available in supply house is this right part i need isvile that is broken below pilot light

I can't tell if you have tankless or tank heater.
Rheem has gone big into tankless the last few years and maybe first models don't have parts any more.

Even so, Rheen probably sells the whole burner assembly.
Most plumbers prefer to replace whole assembly so they're not doing a call-back next month.
Check with Rheem for whole assembly.

Another option is to roll the Rheem heater out of the way and install generic brand from Ace, Home Depot, Sears, or Lowes. Read manual cover to cover to prevent failure. Keep dust, lint and chemicals out of same room. Loosen anode rod before installing. Connect ground wire jumper to hot and cold pipes.
Fix the Rheem when parts become available, or use it as tempering tank to passively preheat incoming cold water, or set tank in wood box with glass cover and make passive solar tank.

Paloma tankless water heater is reading 14 - 0on the display what does that mean

There is a piece of clear plastic film wraped around the heat exchanger. Conductive material (black) is coated on that film. In case of overheating, the film melts, break the circuit and the heater stops. That's how it works, in theory. I had the same problem and had to remove the heat exchanger to inspect the film on the back side. It's a pain in the @#$%, especially found no problem with the film itself. This is what you should do: Find and disconnect connector U in the center of the board with 2 tiny white wires. Measure resistance between those 2 wires, should be 50K~100K. If it's open, either the film is damaged or, in my case, the connector on the film is bad (on the right side of the heat exchanger). Since no other tankless maker uses this protection scheme, I don't think it's doing much. My solution is to fool the controller with a 100K ohm resistor across the 2 white wires. If you're not comfortable with my micky mouse solution, replace the film.

Hi, my halstead ace high boiler has started losing pressure and when i top it up to put the heating on after 10 mins the pressure is high whats wrong with it?

Probably a waterlogged expansion tank. The tank provides a springy air cushion for the water to push against as it expands, and the air pushes back as the water contracts. This scheme minimizes the pressure change that would otherwise be caused by expansion and contraction of the water, giving the water somplace to go when it expands. If the air cushion is gone ... big pressure swings.

Halstead ace high boiler making a whining noise when central heating is turned on also pressure reduces after about 4 hours, need to top up verey day.

Whining = pump bearings
Pressure reduction = pressure relief valve diaphragm either perished of gunged up - look for water coming out of the overflow pipe from the valve
leak in ch system look at all joints

I have a Halstead High Ace which will not light up the light flickers then goes off we have fitted a new dectection electrode but still will not light the boiler We also have flushed the system out ....

sounds basic, but make sure the electrode is in the pilot flame
check the overheat thermostat is not jammed on
disconnect and join wires together for temporary override check and run boiler.
