Think you might need to replace your boiler? Replacing your boiler can be unexpected cost. Thankfully it’s not something you need to do every year. If you take care of your boiler through regular servicing and maintenance, you can extend it’s life dramatically (up to 25 years). That said, however, not every boiler makes it that far. Here are a list of signs that it might be time to get a new boiler:
1) No Heating or Hot Water
If you find yourself without hot water or heating, something is definitely not right! Again, there are a number of reasons why this may happen, but does that really matter when all you want is a hot shower? If you see a pattern or no hot water or heating it may be time to consider an upgrade!
2) Boiler Keeps Shutting Off
If your gas boiler is making a habit of switching itself off sporadically, it may be trying to tell you something. There are a number of reasons this could happen such as pump issues, low pressure, and a faulty thermostat. If this is happening frequently, and you find your HVAC technician is back in front of your boiler week in week out, it might be time for an upgrade.
3) Gurgling or Banging Noises
If your boiler is making funny noises, it could be due to underlying issues from the installation (if this was carried out recently) or it may be something more serious. Gurgling noises can indicate ‘kettling’, which means the system could be filed with sludge, and banging may indicate pump issues.
4) Pilot Light Keeps Going Out
There are a number of reasons your pilot light may go out. It is quiet easy for you to reignite the pilot light on your own, however, if the pilot is persistently going out, it may indicate a more significant problem. Regardless, contact a licensed HVAC technician to investigate the issue.
If you see water leaking from your boiler or into your boiler, this could spell trouble. There are multiple reasons for this but it needs to be investigated immediately. Depending on how long the leak was present and how much corrosive damage was done, you may need a new boiler.
6) Pressure Loss
If your boiler is losing pressure, it could be due to a leak in your system or air seeping through a valve. This is a common problem and can be fixed with something as simple as adding leak-sealer to your system. If the loss of pressure is unrelated to the above, than your boiler may have a serious issue. Again, you need to seek advise from a professional gas fitter and arrange an assessment of the boiler to determine the underlying cause.
In areas of hard water, limescale deposits can build up in your boilers heat exchanger, restricting the free flow of water through your boiler system. Boiler kettling is very damaging and can lead to your boiler needing a replacement. In addition to shortening the lifespan of your boiler, it will also drive up your boiler’s operating costs. Moreover, a clear sign that your boiler is kettling would be rumbling or gurgling.
8) Radiators Not Heating Up
If your radiators are not heating up like they used to, you may need to bleed your radiators, perform a power flush, which removes sludge buildup from your heating system, or get a new boiler. A quick way to test if you that you have a build up of sludge in your system is to feel the temperature of your radiators. If they are heating at the top and not the bottom, itʼs very likely that you have a build up of sludge.
