Is the switch off?

Check the fuse panel/breaker box.

Is the thermostat switch set to heat?

Is system oil heat? If so check the following...

Some systems that use oil have an emergency switch (sometimes with a red plate) located away from the unit usually the basement staircase.

The oil systems also have a heat element above the burner on ceiling that "trips" if there is excessive heat. This shuts everything down so as not to feed a possible fire with oil.

Check the gun (burner itself) and try and locate a little red reset switch located near the back side of gun. Try pushing it in to see if its tripped.

If these quick checks don't help then it would be wise to call a technician to check your system for issues. Heating systems are too critical to "play" with and problems are best left to the pros for safety's sake. Good luck, I hope this helps.

How a Central Air Conditioning System Works
amn_howac.jpg


Facts:
  • The typical central air conditioning system is a split system, with an outdoor air conditioning, or "compressor bearing unit" and an indoor coil, which is usually installed on top of the furnace in the home.
  • Using electricity as its power source, the compressor pumps refrigerant through the system to gather heat and moisture from indoors and remove it from the home.
  • Heat and moisture are removed from the home when warm air from inside the home is blown over the cooled indoor coil. The heat in the air transfers to the coil, thereby "cooling" the air.
  • The heat that has transferred to the coil is then "pumped" to the exterior of the home, while the cooled air is pumped back inside, helping to maintain a comfortable indoor temperature.
  • Central air conditioning can also be provided through a package unit or a heat pump.

Benefits:
  • Indoor comfort during warm weather - Central air conditioning helps keep your home cool and reduces humidity levels.
  • Cleaner air - As your central air conditioning system draws air out of various rooms in the house through return air ducts, the air is pulled through an air filter, which removes airborne particles such as dust and lint. Sophisticated filters may remove microscopic pollutants, as well. The filtered air is then routed to air supply ductwork that carries it back to rooms.
  • Quieter operation - Because the compressor bearing unit is located outside the home, the indoor noise level from its operation is much lower than that of a free-standing air conditioning unit.

Got a baxi back boiler about 20 years old works fine upto the other day when the heating is on the thermosate dos'ent seem to be working the boiler is just running on full all the time and not coming on...


Can you control heat with thermostat by turning it all the way down. I assume from your description that burner is running. If it is and turning t-stat all the way down made no difference I would remove t-stat from wall and remove red or white wires from it.This should cut power to gas valve turning burner off. If this works replace t-stat. Hope this helps. Thanks.

Burner propblem


have you tried to wipe off the fire eye on the unit if it has one? If it's dirty too then it will not see the flame and not let the unit come on correctly. Good Luck and have a Happy New Year.

Bosch greenstar 30 CDi - no central heating or hot water!


it sounds like the system was not cleaned properly when the new boiler was fitted. all new boilers need to have the pipework flushed to remove any debris scale sludge and flux from the system. this is now usually done by a power flush which is basically a big pump mounted on a big bucket and it washes the dirt out of the pipework and collects in the bucket. if this is not done the dirt will block up the small passages in the heat exchanger. i suggest the system is cleaned flush and the heat exchanger changed to help protect the boiler a filter should be fitted (for example a magna clean) if the company who installed the boiler is corgi registered then they are liable for the damages. call corgi for advice.

Ariston micro genus combi boiler central heating works okay but domestic hotwater fails to rise but burners seem to be lit and the boiler doesnt appear to cycle dhw temp gets to about 30 degrees instead of...


having found a circuit diagram, realised that the divertor valve was electrically operated.i unplugged this then unclipped the motor from the valve body,the diverter valve is spring loaded and once i'd removed the motor the spring raised the valve to divert water through the dhw heat exchanger,giving us hot water but no heating, if i refit the motor the problem comes back heating no dhw.ordered new motorised valve assembly £30 next day order .
this was a simple fix without having to drain the system down.

Replace the nozzle, don't try and clean it. After the burner runs a few seconds, do you have to reset the control (red button) before it will start again? Does it sound like there is a pulsation in the flame when it starts or it is running out of oil? You may have a bad ignition control. Start with the small stuff, nozzle, strainer filter, oil tank filter and then work to the more complicated.

My central heating system comprises a worcester bosch system boiler and honeywell smartfit controls. The problem I am having is that the central heating doesn't seem to knock off at the preset temperature...


You could possibly have an ignition problem. The controller will go into a lock-out condition if flame is not established. Turning the temperature control down and then back up may be serving to reset the control system so it tries again.
