6 Things to Look for Before Hiring a Heating Engineer

Are you thinking about hiring a heating engineer for your home? While it’s a good decision to make if there are issues in your home, you might want to rethink the move and instead make these six checks first:


1. Radiators

The radiators of the unit might not be operating efficiently. There’s a problem when the radiators don’t give off enough heat. The cause of this could be because there is a little air trapped in the radiator.

A common problem is a radiator that is a little warm at the bottom and cold at the top. The good news is that the problem is very easy to fix. Taking some basic steps can help to solve the problem. You can research online for relevant articles on this.

2. Cold/hot radiators on different floors

You should first bleed the radiators. Air in the system could be causing the problems. Another option is to check the pump near the boiler. There’s an inspection hatch to see if the pump is turning properly.

3. Boiler’s electricity

This is a major issue to consider if you’re not getting any hot water. There could be an underlying problem with power getting to the heating unit.

Many people make the wrong assumption that gas boilers only get their power from gas. However, power is necessary for powering the unit’s lights/digital display. Making sure they’re working is important.

There are other issues to check if you’re not getting any hot water. That includes the thermostat, timer, pilot light, etc. The problem could be resulting from these items.

4. Boiler controls

Various boiler controls can malfunction, so it’s important to check them. They include the thermostats, programmers, electronic developers, radiator valve, etc. It’s important to check these issues before you call a professional. They’re quite easy to check. You can save a lot of money if you can fix the problems.

5. Pressure decrease

It’s important to check the pressure gauge after you’ve bled the radiators. Other factors can cause the pressure to drop. The primary reason is a leak in the system. The leak often happens around any place of the system where the connection points link with the valves.

6. Noisy boiler

These can involve banging, hissing, or other sounds. Different issues can cause it. That includes scale within the heating system, not enough water/pressure in the central heating system, boiler failure, faulty boiler controls, etc. It’s important to check these issues to find out if they’re causing the noises.

The Process of a Central Heating Powerflush

Does your home have central heating? It’s very common, and such systems require the proper maintenance. That includes a power flush. The process involves removing dirty water in a boiler end system, which includes iron oxide sludge. It requires a particular machine that’s linked to a central location.

The vast majority of homeowners don’t own the right equipment to do a powerflush. That’s why it’s important to hire a professional to handle the work. The process helps to clean the entire system, yet doesn’t require removing the radiators, which is a plus.

Workers add powerflush cleaner to the system water. That helps to start loosening rust. Then the heating is switched on, and cold spots are checked for on the radiator’s surface. Workers then flush water throughout the single radiators and cold spots that are vibrating. That helps to loosen the sludge quickly. The slurry moves out from the radiators. Magnet filters are then to collect it.

The flushing of the radiators and pipes continues until the workers collect water samples that are both clean enough and also pH neutral.

Next, a corrosion inhibitor is then added to the system’s clean water. Workers then balance the radiators.

Companies often provide a certificate after the work has been completed. That’s because it’s a written record that the heating system has had power flushing done. It’s critical for your records in case you have any issues in the future.

You might be wondering why you should consider the power-flushing process for your heating system. Here are some of the main reasons you should take the step:

  1. Fuel wasted

When boilers haven’t undergone a powerflush, various types of debris including deposits, rust, sludge, etc. build up. That reduces the flow of water and heat from getting to all of the system’s parts. The loss of heat means that you’ll have to turn up the heating system. That will result in extra costs.

  1. Cold radiators

When radiators at hot at the top but cold at the bottom, it shows that there’s sludge build-up in your heating system. It’s a result of a build-up of iron oxide-based sludge at the radiator’s bottom. That results in the flow of water being restricted.

  1. Total boiler breakdown

If your boiler has problems, there’s a chance it could overheat because of extra heat build-up. That’s caused by deposits and sludge reducing heat transfer.

  1. Limited hot water

It could be caused by blocked pipes as well as heat exchange because of the extra build-up of deposits/sludge.
