OUR ONLINE BOILER QUOTATION TOOL

We have an online boiler quotation tool, for those customers that are happy to work through some simple questions about their home and know what they want. However, if you would like a personal visit from one of our heating engineers, we are still more than happy to come out to visit you in your home, adhering to Covid guidelines of course, and discuss your requirements and needs in detail with you.

WHY HAVE A NEW BOILER?

SAVE MONEY

In these hard times we are all looking at ways to save money. Your increasing gas fuel bill is one area you can reduce costs by fitting a new high efficiency boiler. These are 90% efficient where as a conventional boiler efficiency can be as low as 60%.

HOW MUCH COULD YOU SAVE? 

This will depend on how old and inefficient your existing boiler is.

Old boiler ratingAnnual savingCO2 saving per year
G ( < 70%) £3001,220kg 
F (70–74%)  £200810kg
E (74–78%)£150610kg
D (78–82%)£105 420kg

These are estimated figures based on installing a new A-rated condensing boiler and full set of heating controls in a gas-heated, semi-detached home with three bedrooms.  

WHICH TYPE OF BOILER DO I NEED?

It’s complicated, as they say… so let us help to explain some heating systems.

WHAT IS A “CONDENSING BOILER”?

Condensing boilers are now mandatory and are much more efficient than their predecessors. They achieve their high efficiency by converting the water vapour condensation into heat, hence their name.

With ‘conventional’ boilers, not all of the fuel burnt reaches the heating system to warm your house, some of the hot gases escape up the flue. However, a ‘condensing’ boiler captures some of that heat and re-uses it meaning they deliver more heat from the same amount of fuel, which will save you money on your heating bills.

Modern boilers can be installed in a variety of ways, either conventional, combination or system configurations. However, what does all this mean?

CONVENTIONAL BOILER INSTALLATION

These are also known as ‘open vented’ or ‘regular’ boilers. They have both a hot water cylinder and a supply tank.  Storing hot water is key to this system; a plentiful supply of hot water is always available. You will require space in the loft and airing cupboard for tanks.  

Advantages:

  • Hot water available from multiple taps at the same time.

Disadvantages:

  • Instantaneous hot water not available, it has to be heated first and then sent to the hot water cylinder.
  • If the hot water runs out you have to wait for it to reheat.
  • Space is required for the hot water cylinder and a supply tank.

Most suitable for:

Homes which need to have hot water in more than one place at the same time.

COMBI BOILER INSTALLATION

Combi boilers are the most popular kind in the UK.  They provide instantaneous heating and hot water with no space required for a hot water cylinder or supply tank in the loft or airing cupboard.

Advantages:

  • Unlimited heat and hot water when you need it.
  • No need for a hot water cylinder or a tank in your loft.
  • Small installation space requirement.

Disadvantages:

  • Water pressure might be reduced (flow) if you need hot water from more than one tap at a time.

SYSTEM BOILER INSTALLATION

System boilers, are also known as ‘sealed systems’.  They are similar to a regular boiler in that they have a hot water tank but they do not have a supply tank and are filled directly from the cold feed instead. 

Advantages:

  • Hot water available from multiple taps at the same time.
  • No need for a tank in your loft.

Disadvantages: 

  • Instantaneous hot water not available, it has to be heated first and then sent to the hot water cylinder.
  • If the hot water runs out you have to wait for it to reheat.
  • Space is required for the hot water cylinder.

Most suitable for:

Homes which need to have hot water in more than one place at the same time.

WHAT BOILER IS BEST FOR ME?

A regular (conventional) boiler is actually more efficient than a combination boiler at producing hot water in the first place, but then some heat is lost when the water is stored in the hot water cylinder, so a combination boiler can be more efficient overall. 

The best option for you will depend on a number of factors:

How much hot water do you use? 

A large family using lots of hot water could be better off with a conventional boiler – a smaller household using less, may be better off with a combi.

Are you short of space? 

A combi boiler doesn’t need a hot water cylinder, and so needs less space.

Are you thinking of installing solar water heating?

Many combis are not compatible with solar water heating or cannot use it so effectively.

FITTING

Once you’ve decided on the type of boiler, you then need to make sure that you choose the most efficient model and get it installed safely and legally by a Gas Safe registered engineer.  

We only use reputable manufacturers such as Vaillant, Worcester, Glowworm, Viessman, Baxi, Potterton. We do not limit ourselves to one manufacturer as we believe that every customers is different and not that “one size fits all”. Our online quotation tool will recommend the boiler that we feel best suits your home.
