The boiler doesn't heat up--the on light never goes off and there is not hot water. What is most likely the problem--I'm not particularly techy but I can understand non-technical explanations of technical problems. Thanks.

For clarity, a Furnace produces HOT AIR for heat while a boiler produces HOT WATER for heat. Just remember...boil = water. You said your "furnace" does not produce hot water for a shower and because furnaces do not product hot water unless they have some model that do???? Usually people with a furnace have a seperate hot water heater. People with boilers though can produce hot water for use as both their sinks/showers hot water and their heat (by heating water that goes through baseboards) in their house. I don't believe any furnaces produce hot water most of the time a furnace just produces hot air for heating. So figure out what you first have.
Having said that, I'll assume you have a boiler like I do and my Weil McClean(sp?) stopped working a while back and wasn't turning on to "boil" any water. I took apart the burner and there is a light sensing photo resistor as part of the controls. If this phto resistor goes bad, the boiler will not start. The resister is cheap, I think it was $8 but you have to know what you're doing to change it. So you may be better to call someone who can work on such equipment.
Boiler's themselves are not overly complex. Home heating oil is the same diesel fuel that you can buy in a gas station only the government has "oil" companies put a RED die in home heating fuel which is usually cheaper then Diesel fuel because diesel fuel is taxed to death. The reason they do that is so that if you try putting RED tinted home heating fuel in your truck and you get pulled over (because you're a trucker with and 18 wheeler and they typically do inspections of these trucks) you will be a huge fine if they see you're running home heating fuel and NOT paying your taxed by purchasing Diesel fuel. A little bit of background so you know the fuel you are dealing with here. So it's dieslel fuel without the tax you run in your boiler. Gasoline on the other hand is VERY explosive as you know, but diesel fuel (if you're ever tried to light it) takes some coaxing to get lit. When it's cold out, diesel fuel is very hard to light and that's why trucks use glow plugs. You don't need those in your home though.
But because diesel fuel/home heating oil is hard to light, it's sprayed as a msit into your boiler, so that it can light more easily.
But because it is a fuel, you should know what you're doing when messing with it. FInd out what you have, and then have someone work on the issue if you haven't already. I'm guessing you have had it fixed by now?
then there must be a problem with the programmer as the boiler thermostat will call for heat only if the programme is on try setting the water side to 24 hrs it won't cost any more to run , but will prove if programmer is working .
Hi - hope someone can help. I have a VOKERA EXCEL 80SP combi boiler and been without hot water/central heating for two days. The pilot light is on, the fan is on, but boiler not triggering once the hot water tap is turned on.
Hopefully someone come to look at it today but hoping for some advice. Anyone else had this problem?
I have a BAXI combi Instant 105 HE bolier. It has been very cold for the past week and the hot water is not working (though the heating is). I have cleared the overflow flu pipe of ice but this has not solved the problem. Any suggestions?
The reason i ask is because I don't think you have a problem.
On this boiler it has a 'pump over run' thermostat incorporated into it, this ensures heat escapes from the boiler by using the pump to cool it down.
If you are getting hot water and heating, leave it well alone, if you reset the boiler this can have adverse effects on the boiler and evenually cause malfunction.
However, if you find that you are not getting Hot Water or Heating, then the most common fault on this boiler is the PCB (Printed Circuit Board) it is the 'brain' of the boiler and the most common fault on this make. (£160 + vat)
