Operating worcester bosch 240 gas boiler


Control systems operate on a much lower voltage than the boiler. You should be able to put any kind of thermostat in for it. Just be sure of the wiring when doing it. If its a line voltage stat, I'll need more information to advise correctly.

Ravenheat 80/20 boiler. the boiler looses water pressure but only when working in central heating mode. Boiler holds pressure indefinitely if central heating is not used,hot water can be drawn without a...


Hi, your boilers pressure should be holding 1.5 bar with the relief set about 3. If the pressure is below this the flow switch will cause the boiler to stop as theirs not enough pressure to operate. Another thing, does your boiler have an auto fill system or do you need to plug a hose in to fill it? If its an auto fill system and you lose pressure you could have a leak.

Keeps giving a code of ops on boiler and will not kick blower on


Are you certain this is a boiler? Furnaces use blowers; boilers do not.

Could you be referring to an induced-draft small blower motor that normally runs immediately on a call for heat?

Is there an electronic control board measuring about 6 inches by 8 inches visible?

We can help if you give us a model # and brand name. Does it operate by oil, natural gas, or propane (LP)?

Ferroli boiler error code A3


boilers need a certain amount of water pressure to operate as specified--there may be a pressure regulator valve, allowing a certain amount of water to your boiler, and when water is drawn elsewhere, there may not be enough getting to the boiler---this is one possible solution, but there are easily 20 more, and that is where a trusted plumber is worth it's gold...very difficult to diagnose most plumbing problems without being onsite

If this is a newer boiler, if it has a control board with a 24volt output
check to make sure boiler has line voltage to it. No fuse Blown/Breaker
Tripped.

If that is not the problem and power is available it could be the thermostat. If there is a pump involved,make sure it can operate

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.
