Question about Air Conditioners

1 Answer

I have a old Trianco gas Boiler, that is still in good condition.when the boiler is satisfied on temperature and turns off, i have a rumbling noise.this i have been told is due to the pump shutting off the same time as the boiler.And to rectify this the pump should have a overrun stat,to allow it to run on a few seconds to pump the hot water from the heat exchanger.Is this correct and can it be done

Aquastat pops reset when reaching temp.


Aquastat cycling controls do not have a reset button. What you are looking at is a manual reset limit switch. That is a safety control set at the MAXIMUM allowable temperature for the boiler to attain. More than likely the actual cycling control is not cycling at the correct temperature allowing the overtemp condition. The cycling control will be very close in external appearance to the limit switch but it will not have the red reset button and it is wired in series with the limit control and will turn the boiler off and on automatically based on its setpoint.

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.

Where do i adjust boiler temp on a gas fired boiler


difficult to say just where the temperature control is on your system. it will likely be an immersion type control located some on or near the boiler. it should have a temperature range scale on it.

Does the boiler thermostat control the heat of the radiators as well as the hot water temperature? Does the thermostat control the water temperature and the pump - as our pump seems to be on all the...


There should be a control called an aquastat that regulates the temperature of the boiler. The thermostat will turn on the circulator to start the flow of water through the radiators. If the water coming back from the radiators is very cold, a control will shut off the circulator until the boiler can come up to a predetermined temperature then start the flow of water again. If you have a tankless coil for domestic hot water, you now have a triple aquastat that maintains the temperature for domestic as well as the boiler temp. So yes the boiler thermostat (aquastat) does control the heat of the radiators and domestic hot water. No the pump is regulated by your house thermostat. You should take an amp draw on the boiler and componants to find out what is drawing more electricity than it should and popping your fuse.

The boiler stopped twice during a week. The reset button was pressed whenever to start the boiler again(twice during a week). Is it abnormal? Does the reset button need to be replaced?


Good Question!-- Let's see if we can figure this out--

What kind of fuel are we talking about? - Gas or Oil?

Any clue as to WHY the boiler stops?--
Can you see a water level, or a temperature or a pressure setting/ gauge?
Tell us what some of these readings are--

If it is gas-- how does ignition take place?-- Spark, or ignitor ignition?

Where is the Reset button?-- is it on the burner control-- or the water level control?

Tell us more--

You gave a good description of the boiler--
now we need to hear the clues you have observed, as it fires (or fails to fire-- or what?)

Or as the water flow-- or doesn't flow?
As the cold water enters-- what does the flame do?
And does the flow rate reduce as the flow gets to the divert er valve?

How old is the boiler?-- and have we been using HARD water?
(Any water softener in the circuit to remove calcium and magnesium, etc.?)
Do you suspect a scaling problem in the interior parts?
If so-- can you circuit an acid thru the innards, to clean up the scale?

Please comment on what happens when water and gas flow-- so we can help you get to the next step.

Have raypac spa pro electric heater. set thermostat to start turn on timer heater contacts pull in heat starts then contactors fall of line. flow through pump is good,


the high temperature limit may be shutting off the heaters when they registera high temperature conditiojn that is dangerout. Have you gotten to run the heater long ehough to take a temeperature reading betweeen the supply and the return? also do you have strainer in line with the piping to the boiler.and is there a pressure switch for if the unit develops too much pressure. And how can you tell how many gpm your moving thru the boiler? these are the thing that a compenent service technician can check out and correct the prolem. exspecially since this is a boiler and if its improperly repaired it can explode and do lots of damage..that being said I strongly reccommend that you call a service company to service your boiler. THaanks for using Fixya

Hi,i have a vaillant turbomax combi boiler,the radiator side is working well but when running hot tap the boiler kicks in for about 5 seconds ,hot water starts to flow then boiler cuts out,water runs cold...


Which turbomax, as there a two different models. The more modern one, with the brass CPL diverter valve, located at the front left of the boiler, was very prone sticking & jamming, this would restrict flow through the hot water circuit in the boiler, and cause cycling. Vaillant actually modified the diverter. You can identify, if it is the old type, as there is a very small hole in the middle of the diverter on the old ones, probable no more than 1mm-2mm wide. The modfied one, is much bigger approx 5mm wide. If old type, replace as this usally sorts the problem

I have a vitodens 100-w combi boiler and tried to turn the heating on just to give it a working as was advised. However, I have no heat coming to my radiators. The boilers seems to be working as my hot...


Here's the deal: If your Vitodens 100 has outdoor temperature sensing capability, either built in or via external aftermarket control such as Tekmar or other, and the temperature outside is above warm weather shut down (WWSD), then the boiler will not operate for space heating, but will operate to make Domestic Hot Water (DHW) only. Generally speaking WWSD is facoty set at 20*C, since this is normal room temperature so the boiler will not need to operate at temperatures above this number as it is warm enough outdoors to heat the house to comfortable levels.
If your Vitodens 100 does not have outdoor temperature sensing capability then you should check to see if your room thermostats are operational and calling for heat since the boiler is only responding to this on-off control based on room temperature. (turn up your room thermostats)
In both cases you need to make sure that your heating system's distribution pump and zone valves are operating correctly.
In any case you should be calling a heating contractor if you suspect that there is a problem with your boiler and/or heating system.
Good luck.
