What are the cons of combi boilers?

  • Combi boilers can struggle with high water demand. Having multiple taps or showers on at the same time may lead to one of them to go cold. A combi boiler is not recommended when you have more than one bathroom. 
  • Combi boilers require high pressure water from the mains. If you live in an area with low water pressure, then the water coming from your taps will also be at low pressure. 
  • An old plumping network might not be able to cope with high pressure water flow from your combi boiler. So your home might require new pipes before getting a combi boiler. 

System boilers

System boilers work together with a hot water cylinder in order to provide hot water and heating for your home. System boilers take water directly from the mains.

  • When you use all the hot water stored in the cylinder, you’ll need to wait for the boiler to heat some more.
  • System boilers need a hot water cylinder so if you don’t have enough space at your home they might be inconvenient for you. 
  • If you live in an area with low water pressure, a system boiler might not be the best choice. What is more, if you have old radiators, they might not be able to cope with the high water pressure of a system boiler. 
  • Due to having more parts than a combi boiler, a system boiler might require more maintenance. 

Regular boilers

Regular boilers or heat-only boilers can provide both hot water and heating to your home. They are designed to draw water from a cold water tank and to store hot water in a hot water cylinder.

What are the pros of regular boilers?

  • Replacement is simple and easy 

Replacing your old regular boiler with a newer version is less costly and damaging to your home. So it’s always the safer option to go with if you don’t want to spend a lot or worry about damages. 

  • Meets your high demand of heating and hot water 

If you have a home with multiple bathrooms, then a regular boiler is a great choice. It can meet your demand for hot water and heating. With a large capacity to store hot water, it means that you can use several taps and outlets at the same time. 

  • More efficiency 

Older boilers with no condensing technology should be replaced with a condensing boiler. Condensing boilers are more efficient and consume less energy. As a result, they will reduce the cost of your heating bills. Nowadays, some regular boilers are 97% efficient. 

  • Able to have an immersion heater as a backup 

A backup immersion heater would make sure that you don’t go out without hot water in case your boiler breaks down. The immersion heater would be fitted in the hot water cylinder. 

  • Solar compatibility

Read about: Regular Boilers and how does it works

What are the cons of regular boilers?

  • Hot water isn’t always instant in busier times 

Once you use all the stored hot water in your cylinder, you have to wait for some time to be able to use hot water again. Always buy a cylinder with the capacity to meet your hot water demands and needs. 

  • Needs lots of space 

Regular boilers need space for the water tank and the hot water cylinder. That’s why it’s not a good choice for smaller homes that don’t have much space. For smaller homes, a combi boiler is more suitable. 

  • Installation can be costly 

Because there are many parts to be installed around the house, a new boiler installation can be pricey. Aside from being expensive it can also take a lot of time.

Although combi and regular boilers are different in some ways, it’s not such a bad idea to replace your conventional boiler with a combi one. You just have to make sure that a combi boiler can meet the hot water and heating demand of your home. 

Generally speaking, replacing any type of old boilers is a great improvement since new boilers use condensing technology and are much more efficient. In short, you will pay less money on energy bills to achieve the same end. Condensing boilers can also help reduce your carbon footprint if that is your concern. 

Without a doubt, combi boilers have many advantages. There are many reasons as to why you should replace your conventional or regular boiler with a combi boiler. These pros will be discussed in this blog. 

Best Condensing Boilers

How much does it cost to replace a regular boiler with a combi boiler?

  • Brand
  • Model 
  • Size
  • Efficiency 
  • Warranty length 
  • Other special features

The installation costs can vary based on different regions in the country, the rates of your heating engineer. However, the main factor that affects the price of installation is the complexity of the job at hand.

Factors to consider when selecting a boiler

As has been noted, a new boiler replacement might not be that cheap. So it’s important to consider some key factors before making your final decision.

The size of boiler you need (kW output)

When we talk about boiler size, we do not mean its dimensions, but rather its power output. The unit of measurement, used for boilers, is the kilowatt (kW).

To clarify, the higher the output of your boiler, the more powerful it will be. Nonetheless, it’s never a great idea to get the boiler with the highest output rating. A too high output rating would increase your energy bills. And a too low output rating will not meet your demand.

Through counting the number of bathrooms and radiators in your home, you can find the most appropriate output rating for you. This information can also help you have an idea of the level of demand for domestic hot water and central heating.

With this purpose in mind, we advise you to get a quote from a Gas Safe registered engineer. If you have a brand in mind, then you should check their website and guidelines. A lot of manufacturers, nowadays, offer advice on their websites.

Boiler Installation in Reading

Importance of hiring a Gas Safe registered installer

A Gas Safe Registered heating engineer can ensure that your boiler installation will be safe and as smooth as possible. There are several risks involved in boiler installation associated with gas and carbon monoxide.

In order to keep your home and your family safe, we advise that you always get a Gas Safe Registered engineer to install, maintain and service your boiler. Make sure to check that your installer is Gas Safe Registered.

Step-by-step guide to installing a boiler

There are several and different processes involved in installing a boiler. These depend on the complexity or complication your installer might face during work.

The number of steps differs of course. For instance, replacing a like-for-like combi boiler would require fewer steps than replacing a combi boiler with a system or a heat only boiler. Changing the location of your boiler might also mean more work and extra steps.

Aside from how complicated the work can be, three main steps are necessary for your new boiler installation.

First Step: Removal of the old boiler

Before a heating engineer can start with the installation of your new boiler, the old line will need to be removed.

This can be made easier for them if you clean the space around your boiler to make sure that they have easy access to your boiler.

If your boiler is fitted in the attic, then it should be accessible via a set of stairs and a safe walkway, and the room should be lit sufficiently. For a more complicated boiler fitting or the relocation of a boiler, the heating engineer may need to remove old pipework and radiators, before installing the new boiler.

Second Step: The installation of your new boiler

After the removal of the old boiler and pipework, the heating engineer will start with the installation of your new boiler and its pipework. This step might be extremely quick, depending on how much work is needed and how complex the job ahead might be. It will not take a long time if you are getting a like-for-like boiler.

Third Step: New boiler product tour

A product tour will take place after the completion of the installation process. A heating engineer will check to make sure that your boiler has been properly installed. Then he will show you the ropes. You will be instructed on how to use the controls, the features of your new boiler and how to set a schedule for your boiler to be turned off and on. Make sure to ask the heating engineers about anything that you might need help with. Taking notes might also help you in the long run to maintain your new heating system.

Safety checks and testing after installation

After the installation is complete, safety checks and tests will be carried out by our installer to ensure that your boiler is working properly and smoothly.

Regular maintenance and servicing for optimal performance

Regular maintenance and servicing are equally important if you want your boiler to last long and to operate as efficiently as possible. Servicing your boiler and fixing any issues in their early stage can prolong the lifespan of your boiler.

More Complex Systems

In order to operate efficiently, condensing boilers have a more complex internal system. As a result, they might be prone to have more issues. A common issue with condensing boilers is a blocked or frozen external condensate pipe in extremely cold weather. 

What is more, the condensate can lead to corrosion if not well maintained. That being said, condensing boilers are still worth the investment due to their high efficiency. 

Condensing

How can I choose the best condensing boiler for my home?

When choosing the best condensing boiler for your home, there are some important factors you need to consider. These are things that can help you make the best possible decision. These factors include boiler type, house size, output size, fuel type and cost. 

FAQs 

What is meant by a condensing boiler?

A condensing boiler operates by using condensing technology in order to make the most of the heat it generates. Gases are usually released via a flue when a fuel such as oil or gas are burned. In a non-condensing boiler, these gases are released into the atmosphere and any heating potential they have would be lost. 

What are the different types of condensing boilers?

Three main types of condensing boilers can be found in the boiler market. These include: combi, system and regular boilers. 

What is the difference between condensing and non condensing boilers?

Combi boilers have become increasingly popular among UK homeowners in recent years, especially for those living in average-sized homes. While combi boilers offer convenience and space-saving benefits, they can encounter issues from time to time. In this blog, we’ll delve into the components of combi boilers and explore potential breakdowns. We’ll also address common problems associated with combi boilers. But first, let’s understand what a combi boiler is.

What is a combi boiler? 

The term “Combi” is short for combination boiler, a type of boiler that serves dual purposes by providing both hot water and heating from a single unit. This modern system offers several advantages over older immersion heater systems, which relied on water tanks positioned high up. With older systems, hot water wasn’t always readily available on-demand, requiring advance planning to heat water. Additionally, operating older systems incurred high costs and expenses. Furthermore, older systems typically occupy more space due to their larger size.

How do Combi Boilers work? 

In a combi boiler system, cold water is supplied directly from the main water source and heated by burning gas fuel. The heat generated in the combustion chamber is transferred to the water through a heat exchanger.

When the thermostat detects a drop in temperature inside your home, it sends a signal to the combi boiler to ignite and start heating. Once the desired temperature is reached, the boiler modulates its heat output to maintain a consistent temperature, reducing energy waste while keeping your home warm.

Combi boilers deliver hot water to any outlet you’re using, whether it’s a hot tap, shower, or bath. When the tap is turned off, the boiler switches back to providing central heating. It’s important to note that a combi boiler cannot supply hot water to multiple outlets simultaneously; it prioritizes either hot water or central heating depending on demand.

Is a Combi Boiler the perfect choice for your home? 

Combi boilers draw water directly from your home’s mains water supply, relying on the pressure from the mains to provide adequate water flow. If the mains pressure is insufficient, a combi boiler may not be suitable for your home.

Combi boilers have two outputs: one for hot water and the other for home heating. Providing hot water for central heating requires less effort than delivering on-demand hot water. It’s essential to select a boiler that meets your hot water demands accordingly.

Furthermore, if you reside in a large home with multiple bathrooms, a system boiler is more suitable for your needs.

Does a combi boiler use a lot of electricity? 

Although electric combi boilers are more expensive to run than gas boilers, they’re much more efficient. While most gas boilers have an efficiency rating of around 93%, electric combi boilers typically have a 99%–100% efficiency rating.

Combi boilers parts and breakdowns:

1- Air Pressure Switches 

The safety of a combi boiler is ensured by its air pressure switch. This critical component ensures that the fan effectively removes waste gases through the flue before the boiler ignites.

A fan is employed to create the necessary draft to expel harmful gases from the boiler through the flue.

Before initiating the boiler’s firing process, the air pressure switch verifies that the fan is functioning correctly. It only sends a signal to ignite the boiler when the fan is confirmed to be operational.

There are two potential signals from the air pressure switch: one confirming the fan’s proper operation and signaling the boiler’s safety for ignition, and another indicating that the fan is malfunctioning, rendering the boiler unsafe for ignition.

Why does a boiler air pressure switch fail? 

It’s hard to exactly pinpoint why a boiler air pressure switch would fail. There are many reasons. These might include: 

  • A faulty boiler fan 
  • Blocked flue is blocked 
  • A broken PCB 

How do I know if I have a faulty air pressure switch? 

There are some signs to indicate a faulty air pressure switch: 

  • Your boiler will keep turning on and off at random times 
  • The fan is working but your boiler is not 
  • Your boiler is displaying fault codes which are related to faulty air pressure switch 

Is trapped air a problem? 

When air becomes trapped in the heat exchanger, it can impede the transfer of energy, limiting the system’s efficiency.

Ensuring that water makes full contact with all surfaces within the hydraulic or chilled water system is crucial. Any air must be expelled from the system to optimize its performance.

Air can become trapped in various components and locations within your heating system. Therefore, having a mechanism to effectively remove air from the system is vital. This is why an automatic air vent plays a significant role in maintaining the efficiency of your system.

2- Auto Air-Vents (AAVs) 

Loud noises emanating from your boiler may indicate trapped air within a sealed heating system. This can lead to uneven heating in your home and, in severe cases, result in a boiler breakdown. To prevent such issues, regular maintenance of your boiler’s air vent is highly recommended. This ensures uninterrupted heat supply when needed.

Typically installed within cylinder cupboards, the air vent automatically releases trapped air from your heating system.

Trapped air in your boiler can cause pump cavitation or overheating within the heat exchanger, potentially leading to performance issues or system damage.

Why does a boiler Auto Air-Vent fail? 

During operation at high pressure, excess pressure within your boiler system is directed to the auto-air vent. These vents are designed to alleviate pressure levels that exceed the boiler’s capacity. However, there are instances when these valves may become stuck. When this occurs, they may not only release trapped air but also water.

How do I know if I have a faulty auto-air vent? 

  • Water leaking from your boiler 
  • A fault code is being displayed by your boiler .

3- Boiler Expansion Vessel

Inside a combi boiler, there is an expansion vessel whose purpose is to maintain consistent pressure and prevent abrupt fluctuations in your boiler’s pressure.

Insufficient air in the expansion vessel can lead to excessive pressure, causing water to be expelled from the pressure relief valve. Conversely, an excess of air can lead to over-pressurization of the system, also causing water to be discharged from the pressure relief valve.

How do I know if I have a faulty boiler Expansion Vessel? 

  • Poor flow rate from your taps 
  • PRV is dripping 
  • A low-pressure fault code will be displayed  
  • Your boiler will not be able to meet your hot water demand 

4- Boiler Fan 

The primary function of a boiler fan is to expel toxic gases from your home.

When fuel burns in the boiler’s combustion chamber, it releases harmful gases. The flue pipe is responsible for directing these toxic gases away from your home to ensure safety.

While the flue pipe provides an escape route for these gases, the fan plays a crucial role in pushing them further away, preventing their accumulation or slow movement within the flue pipe.

What can cause a boiler fan to fail? 

  • The connections and wiring might come loose due to the vibration of the fan. As a result, the signals going to the boiler’s PCB could be blocked 
  • Fan losing speed over time. A heating engineer could easily fix this problem 
  • Signal issues can also be caused by damaged connection or wiring. 
  • A complete failure of the fan due to wear and tear. The fan should be replaced 

How do I know if I have a faulty boiler fan? 

  • Boiler is making noises 
  • Boiler is not turning on 
  • A boiler displaying a faulty code 

5- Boiler Gas Valve 

A boiler gas valve is responsible for the gas flow to the pilot light and burner as well. An electrical signal from the printed circuit board (PCB) controls this valve.

Best Condensing Boilers

What problems are common with Boiler Gas Valve? 

  • The gas valve can fail to get the signal to work due to connection or wiring problems coming from the PCB to the gas valve.  
  • Your boiler gas valve can get stuck  
  • Faulty boiler gas valve 

You can tell that your have a a faulty Gas Valve if your boiler is displaying a fault code or if your boiler is not turning on.  

6- Boiler Printed Circuit Board (PCB) 

A Printed Circuit Board (PCB) is an essential  part of your boiler.  

To put it simply, the PCB is the backbone of your boiler. It connects the electrical components (pump, timer, thermostat etc) together. 

If your PCB isn’t working as it should, it can lose power, lockout and display and error code or completely shut down.  

PCB problems 

A gas engineer will inspect your Printed Circuit Board (PCB) to identify any issues. If possible, they will repair it; otherwise, it may need to be replaced. The cost of replacing a PCB can be as high as £500. Therefore, it’s essential to consider whether it’s more cost-effective to replace the PCB or invest in a new boiler.

How do I know if I have a faulty PCB? 

  • Your boiler is leaking 
  • Boiler has no power 
  • Burning smell coming from your boiler  
  • Intermittent display panel operation  

7- Circulating Pumps 

Circulation pumps, also referred to as central heating pumps, play a vital role in heating systems. They are responsible for circulating hot water throughout the system.

These pumps ensure a continuous flow of heated water from the boiler to the radiators. The heated water travels through pipes to reach various components such as radiators, hot water cylinders, and towel rails. Subsequently, the water returns to the boiler to maintain a consistent flow of warmth throughout your home.

Combi Boiler Reviews

What are the signs of a faulty Circulating Pump? 

  • The pipe is leaking 
  • The water flow pipe is not hot despite the fact that the pump is running 
  • The pump casing is too hot 
  • You have no hot water 
  • You radiators aren’t heating  
  • Strange noises are coming out of your pipe 

8- Diverter Valve 

A boiler diverter valve plays a crucial role in determining the destination of hot water in your home. Over time, it may develop faults, leading to issues with hot water distribution to either radiators or taps.

Functioning by opening or closing, the diverter valve directs hot water to either radiators or taps/showers as needed. It’s primarily utilized in systems where water is heated on demand, such as combi boilers. System boilers or conventional boilers, which store hot water in a cylinder, do not require this valve.

When a tap is opened, the combi boiler heats water and the valve redirects the hot water to that specific tap. Similarly, when heating is activated, hot water is sent to the radiators. If both the shower and heating are in use simultaneously, the valve prioritizes the shower.

What are the signs of a faulty Diverter Valve? 

  • Only lukewarm water is coming out of your taps 
  • You have hot showers but your radiators are cold 
  • You have hot water only when your central heating is turned on.

9- Heat Exchanger 

A heat exchanger facilitates the transfer of heat between two fluids or substances, typically gas and water, without allowing them to mix. When you activate the heating in your home with a combi boiler, water is sourced from the mains and circulated through your radiators.

During operation, the combi gas boiler burns gas, generating heated gas that rises toward the heat exchanger. Simultaneously, cold water from the mains passes through the heat exchanger. As the water circulates, heat is transferred from the gas to the water, causing it to heat up for use in your tank or to warm your radiators.

In summary, the process involves hot gas and cold water supplied from the mains. Through the heat exchanger, the result is cooler gas and hotter water, with the two fluids remaining separate throughout the exchange.
