What are the Different Types of Boilers? 

Before going ahead with your purchase it’s important you know what you need from your boiler and therefore what boiler would be best for your home. Now, we’re going to take a look at the different types of boiler you can have installed in your home. As well as the advantages and disadvantages of each. 

Combi Boiler

Combi boilers (combination boilers) are one single unit and they generate all the heating and hot water for a home. No water tanks are needed, this is one of the more popular options in the UK because of its space-saving design. Because there’s no water tank storage this means you have hot water at the turn of a tap. 



  • Because there are fewer components needed (water tank and water cylinders) installation is often quicker and cheaper than other methods.
  • The most energy-efficient way to heat your home.
  • Heat on demand.
  • Showers at the mains pressure.


  • Using more than more tap at a time can cause combi boilers problems. This doesn’t make it a great choice for those with larger homes to heat. 
  • It can take longer to fill up a bath because water is heated on demand. 

Conventional Boiler

Unlike the more compact combi heating solution conventional boilers have some of their components housed outside of the boiler itself. The type of system usually requires cold water, as well as an expansion tank in the loft. This method of heating stores hot water in a hot water cylinder inside of the storage tank. Water can be switched on and off as required but is not continuous. 



  • Great for larger homes or homes that use more than one tap i.e they have multiple bathrooms. 
  • Water can be switched on and off as required.


  • No heat on demand- having to wait for the water to heat up. 
  • You can run out of hot water. 
  • You need both the hot water cylinder and water tank in your loft. 
  • Installation can be more expensive as there are more components to be installed. 

System Boiler

Also known as closed vent boilers, with similar components as the combi boiler without the bonus of hot water production. Quite simply to install and there are fewer components overall that could go wrong. A great option for the larger homes where hot water may be required in more than one tap. And a fantastic option for those who live in low water pressure areas. 



  • Suitable for large homes that have multiple bathrooms. 
  • No need for a water tank in the loft. 
  • Simple to install


  • Waiting for water to heat up. 
  • You can run out of hot water. 
  • You need to have space for a water tank. 
  • System boilers suffer heat loss which makes them less efficient than combi boilers.

Now, we’re going to go through our top 5 reasons to choose a Worcester Bosch Boiler for your home. 

1. Market Leading Brand

With over 50 years and so many Which? Best buy awards to mention here, Worcester Bosch means quality. And that’s why they’re the UK market leaders in domestic boilers. Founded in 1962, Worcester Bosch boilers are even inside the Queen’s estate at Sandringham. They have a large range of boilers and cater to all types of homes and people’s needs.

3. Long Lifetime

Worcester Bosch means quality when it comes to boilers, when compared to products from their closest competitors on average Worcester Bosch have a better chance of surviving. Of course, having your boiler serviced each year will not only keep the warranty valid, but it will also increase the longevity of the boiler. 

4. Fits all Homes

As we’ve briefly touched upon above, Worcester Bosch has a boiler to fit all needs and all sizes of homes. No matter how many bathrooms you have, Worcester Bosch definitely has an option to suit your needs as Worcester Bosch makes Combi, System, and Regular boilers. Not only that there are several different options to choose from, so you’re bound to find one that fits the size of not only your home but your budget as well.

5. Parts Availability

Being that Worcester Bosch boilers are the market leaders when it comes to part availability you can be sure there won’t be any problems. Oftentimes we can source parts for Worcester Bosch boilers on short notice. Also, because parts are so readily available they are relatively cheap to buy. This will lower the cost of any problems that do occur with your system.

What Size Boiler Do I Need? 

We’re going to take a look at some of the factors that need to be considered when measuring what size boiler is needed for your property. 

The size of a boiler is actually measured in Kilowatts (kW), rather than physical dimensions. The Kilowatt refers to the unit of measurement used to measure the energy output of the boiler. To put it simply, the more hot water output your house needs the more energy your boiler needs to be able to produce. 

The 5 Factors to Consider

Below are the 5 factors that your Engineer will consider before advising you on what boiler is correct for your property. 

  • Hot water demand – How much hot water does your family use? Do you have multiple bathrooms? Is there a shower on the property? These are all questions that will need to be answered when calculating what type and size of boiler your property requires. 
  • Amount of radiators – How many radiators and how large your home is is another factor that will influence your decision when it comes to choosing a new boiler. 
  • Fuel type of boiler – The type of fuel that is available to your property is another factor that will sway your decision on a new boiler. Seek advice from a professional about what fuel is available to you. Most homes in the UK use Gas which has the greatest level of energy efficiency. However, there are still options for those houses not connected like using an oil-fired or LPG (Liquefied Petroleum Gas) system instead. 
  • Water pressure – Not generally a problem in more modern builds, not having suitable pressure in your water supply can impact what size of boiler you require. Whilst the information about the maxim flow rate for your boiler is probably at your fingertips, a trained professional like one of our team of accredited Worcester Bosch engineers at Greener Homes can help advise you on what is the best option for your home. 
  • Losing heat – Whilst no boiler is 100% efficient, modern boilers can reach up to 90% efficiency. While a boiler that is in its twilight years may well only be receiving 70% at most. This translates over to your wallet too, as you could be wasting over £200 per year.

How Much is a New Boiler? 

Cost of a New Boiler on Its Own

The cost of a boiler system itself can vary from as little as £400-£3,600. All depending on the brand and type of boiler that is needed.

Worcester bosch boilers can range between £750-£3,600 without an installation.

You should never try to install a boiler yourself. And should always ensure that the engineer installing it is Gas Safe Registered.

Cost of a New Boiler Fitted

The cost of a new boiler fitted can vary from as little as £1,500 to £4,500. Again, it all depends on the boiler that you are having installed and the amount of time it takes to install the boiler.

Reasons to Get a New Boiler 

Here at Greener Homes, we consider the boiler the heart of the house, it provides hot water and heat all year round, keeping your loved ones warm and happy. But, how do you tell when you need to get a new boiler? Age is just a number and in the case of boilers with a few tweaks and regular servicing, there’s no reason why you can’t keep your boiler working into its twilight years. 

However, in some situations, there’s no other choice other than having that old boiler taken out and having a new boiler installed.

How Long Will a New Boiler Installation Take? 

When it comes to having a new boiler installation we believe that planning is key, so knowing how long your installation is going to take to complete is absolutely vital. 

Your engineer will take into account several factors like the type of system you’re having installed, its location, and the complexity of the job when providing you with an accurate time frame for your project. Having an accurate time frame should enable you to make plans and preparations while you’re waiting for your boiler to be installed. 

To give you a slightly better idea if you were replacing your boiler in a like for like situation then the time it would take to complete would likely be one working day (4-6 hours). Whilst, fitting a different type of boiler or changing the location of the system could take between one and three days. 

In contrast having an alternative system fitted, such as a heat pump, installation could be between three to five days. 

Do not fear though, You will receive an accurate time frame when booking your installation. Or you can ask before you book in with us, a member of the team will be able to help and advise. To get a quote on a boiler installation click here.

When Should I Get a New Boiler? 

Now, we’re going to take a look at some common signs that your boiler is about to kick the bucket and conk out. 

Frequent breakdowns

Having to call out an engineer to look at your boiler can be a costly and unwanted expense. Having an engineer coming to fix your boiler once probably doesn’t warrant the purchase of a new boiler. However, if you’re calling out an engineer more than once a year this is a sure sign that you need a new boiler. 

Bills are becoming more expensive

At this point, you’ve probably seen the phrase ‘efficiency rating’ when it comes to boilers. But, what does that mean? Simply put, it means a less efficient boiler will cost you more to run. Modern boilers that are A-rated will operate on more than 90% efficiency, whilst G-rated models may run at 70% or less which could be £200 more expensive a year to run. 

Lots of noise

Central heating systems can make a few different noises and hearing a click here or tap there is nothing to be concerned about. However, if you hear humming, vibrating, or banging coming from your system this may well be a sign that something more serious is happening.

If you hear lots of noise coming from your boiler then it’s time to call an engineer to have investigated properly. This is a definite cause for concern if things have changed recently, noises have gotten louder or more frequent. 

Blue flame turns yellow or orange

A sure sign of when it’s time to get a new boiler is if your flame begins to turn yellow or orange. This means that there is a problem with your boiler and you should turn it off immediately. You should then call the Gas Emergency Service on 0800 111 999.

They will help resolve the gas issue, but we advise that you then get your boiler replaced as soon as possible. 

Strange smells

If you can smell a sulfurous or eggy odor when your boiler is in use, this is a sign of a gas leak. Your boiler must be immediately switched off, then please call the emergency gas line on 0800 111 999. Then get in contact with a registered Gas Safe engineer like one of our team here at Greener Homes where we have been installing and maintaining boilers in the bristol area for over 20 years. 

Leaking pipes

Your boiler shouldn’t ever leak water. If it does it’s a certain sign that an internal component has probably broken. However, if left unattended this can lead to structural damage to your property or short circuits that could lead to fire and your family’s safety. If you have leaky pipes please switch off your system and call a professional. 

No replacement parts

Just like your TV and game consoles, boilers have new innovations and designs all the time. So, if your current boiler is in its twilight years it may well be hard to find the correct parts that need replacing. The mounting price of having to scour the internet for replacement parts may well mean that it’s actually more cost-efficient to have your boiler replaced. 

High energy bills

Do you feel like your energy bills are too high in general? Maybe you’ve been chatting with your neighbor and they’ve enlightened you to the fact that they pay lots less than you every month, then this might be a sign that it’s time to get a new boiler. 

A new boiler will be safer

Not only will having a new boiler installation make your bills more manageable, but it will also provide you with a safer alternative than running your old system. New systems are less likely to go wrong in general, when compared to older models, and peace of mind is one of those priceless purchases that will truly help you sleep better at night.

Smart home

In today’s mobile-focused modern world no matter what you’re talking about there’s probably ‘an app for that’ and boilers are no different. With smart home integration, the ability to control your boiler from your smart device is now a reality, and more that makes lots of sense the more connected we become. 

Not Heating Property

If your current boiler is not heating up as quickly as it used or you have no heating at all, it is time for a new one. A major sign that your boiler is on the way out that is it not working as effectively as it used to.#

2. Clean your boiler

Most people’s boilers are in a cupboard or a building outside so when it comes to the daily chores you may well not think about giving the boiler a clean. But, when it comes to prolonging the life of your boiler, giving it a regular clean will certainly help. Also ensuring the area where your boiler sits is cleared of all clutter will help stop the vents from clogging up over time.

However, if you wish to have the inside of a boiler cleaned it’s advised you call a registered Gas Safe Engineer to come and complete the task for you. 

3. Check your boiler pressure

Keeping a keen eye on the pressure of your boiler is another welcome tip from the team at Greener Homes and it’s a really easy one to keep up with. Ensuring your boiler has the correct amount of pressure will help ensure the boiler performs correctly. Checking the pressure once every couple of months is recommended, most systems run around 1- 2 bars of pressure if it falls below this contact an engineer or consult the instruction manual. 

4. Get carbon monoxide detectors

Carbon monoxide poisoning can be lethal and cause serious potential health risks for you and your family. Buying a carbon monoxide meter is a cheap but effective way of knowing that in the case that your boiler does begin to leak, you’re going to be notified immediately. 

5. Get a regular power flush

PowerFlushing is essentially cleaning out your radiators. Over time radiators can get filled up with sludge, rust, and other debris. These elements will prevent your boiler from being able to circulate the hot water around them. A sign that your radiators need to be flushed out is the boiler becoming increasingly noisy.

6. Bleed your radiators

One of the most common methods of maintaining your boiler is ensuring that again the water can circulate around the radiators in the manner it’s intended to. From time to time radiators can get air trapped in them, to prevent this you can bleed your radiators, this is a quick reasonably easy job. Bleeding your radiators is most recommended to do just before the winter months arise in the early autumn time.
