How To Get Your Central Heating System Working Again If It’s Blowing Cold Air

If you’re experiencing problems with your central heating system, there are a few things that you can do to try and fix it. This article will teach you how to diagnose the problem and how to fix it if it’s something relatively minor. If the problem is more serious, or if you can’t get in touch with your boiler supplier, then you’ll need to call a professional Plumber Leicester.

What is a Low Boiler Pressure

If your central heating system is blowing cold air, there may be a low boiler pressure problem. A low boiler pressure can result from a variety of issues, but the most common cause is a clogged or blocked heat exchanger. If the heat exchanger is blocked, the water in the boiler cannot reach its boiling point and steam cannot be produced to heat the home. In order to diagnose and fix a low boiler pressure issue, you’ll need to take into account the specifics of your home’s heating system.

How to Identify if You Have Low Boiler Pressure

If your central heating system is blowing cold air, there’s a good chance that your boiler pressure is low. Here’s how to identify if you have low boiler pressure:

  1. If the system is not warming up, check the boiler pressure. Boilers typically produce between 6 and 12 psi of steam at full load. If the pressure is below 6 psi, the boiler may need to be replaced.
  2. If the system is already warm, but the pressure isn’t higher than 12 psi, there may be a problem with one or more valves in the system. Check for leaks around joints and fittings, and replace any that are found. Finally, check for clogged heat transfer tubes near the furnace or heat exchanger (if present).

How to Tell If You Need a New Boiler and Central Heating System

If you notice that your central heating is not keeping your home warm, it may be time to replace your boiler and/or central heating installation. Here are four signs that you need a new system:

  1. Your home is consistently cold in the winter.
  2. You have to use the heating system a lot more than usual in the winter to keep your home at a comfortable temperature.
  3. You have to open all the windows in your home to get any warmth from the central heating system.
  4. Your energy bill is high in the winter compared to other seasons.

If you’re like most homeowners, you probably don’t want to spend the money necessary to replace your boiler and central heating system. There are a number of alternatives available to you that can save you money on this important repair. Here are four of the best:

  1. Switch to an Electric Heating System:

One of the best alternatives to buying a new boiler and central heating system is to switch to an electric heating system.

They also use significantly less energy, which can save you money on your electricity bill.

  1. Consider a Solar Heating System:

Another great alternative to buying a new boiler and central heating system is solar heating. Solar heating systems work by using solar panels to convert sunlight into heat, which can then be used to warm up rooms in your home. They’re relatively affordable, and they typically only require occasional maintenance in order to keep them running smoothly. Plus, they produce zero emissions so they’re environmentally friendly as well as cost-effective.

  1. Upgrade Your Existing Gas Boiler:

If you currently have a gas boiler in your home, it might be worth upgrading to a more modern unit instead of replacing it completely. New gas boilers tend to be more efficient than older models, which can save you money on your energy bill over time. Plus, they typically come with


If your central heating system is blowing cold air, there are a few things you can do to get it working again. First, make sure that the thermostat is set to the correct temperature. If it’s too high or too low, the system will not work properly. Next, check for any obstructions in the system such as pipes that may be blocked or filters that need to be replaced. Finally, try restarting the unit by turning off all of the breaker switches in your home and flipping them back on one by one until you reach the central heating unit.
