If your boiler breaks down, you could be without hot water and heating for a while. It can be tough figuring out what’s wrong. That’s why people choose Denver boiler repair!

Some boilers, especially old boilers, only have a pilot light to tell you whether they’re working right or not! So when it comes to trying to fix your boiler, you have to rely on the pros. Here are five of the most common problems that we encounter fixing boilers in the Denver area.

Denver boiler repair: has your pilot light gone out?

Boilers are a great alternative to furnaces and other home heating methods. Unlike heat pumps and furnaces, boilers work by heating water, not air. They do this by burning natural gas and fuel, or in some cases, working with mains electricity. The majority use fuel. Even the oldest boilers used a pilot light, so that you could quickly check that the boiler is switched on and working. So if the pilot light isn’t staying on, it’s often the first sign that something’s gone badly wrong.

If your pilot light has gone out, it could be because of a faulty thermocouple or a loose or damaged seal. It either means that the gas supply isn’t getting to the pilot light either because of damage, or because it’s run out. Either way, your boiler will need either repair or maintenance. This is especially the case with older boilers, in which the pilot light is more prone to being extinguished, because of their less efficient and stable manufacture.

Denver boiler repair: is your boiler making strange noises?

All boilers make some kind of noise now and again. Modern boilers especially are guilty of this. They refill, heat up and switch on and off completely automatically. So you may be sitting on the sofa, watching TV, when it decides to switch on on it’s own. But some noises don’t sound… healthy.

You should be especially concerned if you hear a whistling noise coming from your boiler. If you’re of a certain age, you may have had a kettle you could warm up on the stove, that would whistle- just like you might see in something like in Tom & Jerry. Well, the reason for that is that the steam from your boiler is whistling through your pipes. Why? Because of the buildup of limescale which has made them narrower, almost like a clogged artery. Your boiler also might be guilty of making clanking or gurgling sounds, which can have a number of causes. If your boiler starts making a new and unusual sound, and making it regularly, you should seek out a repairman to fix it as soon as possible.

Denver boiler repair: does your boiler randomly switch off?

Today’s modern boilers can turn off for a number of reasons. Boilers today are designed to work automatically, with very little input required. You don’t have to tell them to heat up, or to stop, because just like modern AC you can set the temperature you’d like and leave it at that. But sometimes, your boiler might switch off at unusual times, like before it’s fully heated your home.

Your boiler might be switching itself off in response to a drop in water pressure, not having enough water, a fault somewhere in the system or even a problem with the thermostat. These problems are all fairly serious, so it’s advisable to seek out a professional rather than try to fix it yourself.

Denver boiler repair: is your boiler leaking?

Water leaking out of your boiler is, under no circumstance whatsoever, a good thing! There are a couple of reasons that it might be happening. Either some component has been damaged quite severely inside the boiler, or a seal has come loose or corroded away. Generally, a loose seal will produce a drip and damage will produce a more steady stream of water. But drips can quite quickly become streams if not attended to.

Damage inside the boiler is most often caused by pressure, either pressure that’s too high or pressure that fluctuates too much. Pressure gradually exacerbates manufacturing faults in the pipe. It can also make very minor damage into more major damage. Damage from other problems is uncommon because most boilers have very few moving, mechanical parts. There’s therefore little else that can cause pipes in your boiler to burst or leak.

Denver boiler repair: has your boiler’s pressure dropped suddenly?

A drop in your boiler pressure is most commonly caused by the point above! If your boiler is leaking either water or steam from any part of the system, it can cause the pressure inside your boiler to drop. This will stop your boiler from being able to properly heat your home. Eventually, it will stop it from working altogether. The only exception is the condensate pipe, which is used specifically by condensing boilers. It’s used to drain away- you guessed it- the condensate created by the boiler’s operation. Not to go into too much detail, but condensing boilers use the heat from the exhaust gas as further energy, and others don’t. The only thing they require is a way of getting rid of the condensed water they make.

Anyway- if your boiler’s pressure drops unexpectedly, this means that either your boiler has been damaged or it’s not getting enough water for some reason. Neither is good.
