What Our Customers Are Saying

What to consider when replacing your Gas Boiler

Location Location Location

The location of your new gas boiler and model is likely to impact install time and costs, particularly if you have decided on a relocation. Below are some things to consider when deciding on your new gas boiler replacement.

Gas Boiler Brand/Model

The model and brand of gas boiler chosen will impact on your price. The higher the quality of the selected boiler the higher the costs associated with it, for this reason we have a selected range of gas boilers to suit every budget while minimising the difference in quality.

Do you need heating controls?

Correctly installed heating control will not only reduce your fuel bill but will also make for a easier controlled, better performing central heating system. Dependent on the level of heating control required the installation time and cost will be impacted although grants are available to offset this additional expense.

Do you need to upgrade your gas pipe?

Your new “A” rated condensing gas boiler may require a larger gas pipe dependent on the distance from the gas meter, current pipe size and the amount of gas appliances served by the current gas line.

In addition if you are planning on relocating the new gas boiler, provisions will have to be made for re-connection of the existing heating system piping to the newly installed gas boiler. Floors coverings may have to be temporarily removed to allow the routing of piping to serve the boiler in its new location.

Condensate Disposal

Your new high efficient boiler will require a means of discharging its water vapour by product to a suitable drain or soak away. 

Boiler flue location and route

The length total lenght of flue and Flue terminal location are two very important factors to be considered when choosing you boiler location. A boiler located internally with no direct access to an outside wall will require addtional flue lenghts and components and this will impact your expenditure.

If your flue is concealed you may require addtional safety cut off controls

Do you require Independent heating zone control?

Dependent on your current heating system capabilities additional piping and cabling may be required dependent on the type of zoning required. (Hot water and Radiators)

How much space does the boiler require

Boilers come in all different sizes and with that their minimum space requirements vary greatly. It’s Important to note the minimum space requirement for service, repair and Installation.

 

Gas Boiler Efficiency  

If you have gas fired central heating in your home, your gas boiler is the main component of your central heating system. It produces the heat energy we require for both warmth and hot water. On average your gas boiler will be responsible for around 60% of your homes carbon emissions and equally the single largest consumer of energy in our homes. It is because of this high energy usage; careful consideration must be given to boiler efficiency in order to reduce both your energy bills and carbon footprint. Modern condensing gas boilers are typically over 90% efficient and replacing your old fashioned central heating boiler with one could mean a saving of over 20% on your annual gas bill.  In Ireland, there are many condensing boiler brands and models to choose between. But in term of efficiency levels there is very little difference between them. The most important factor when choosing the most efficient boiler for your home is the correct type and sizing. 

Gas Boiler Reliability 

When considering replacing your boiler, one of the most important things to consider is reliability. Just like cars there are many different makes and models to choose from, each with their own range and each offering very different levels of quality reliability warranty and pricing. No boiler can be considered 100% reliable but in the event that you are unlucky enough to experience a boiler fault, warranty back-up and support are also important factors to be taken into account. According to an independent survey by Which.co.uk the most reliable boiler brands are Worcester Bosch and Valliant. Being accredited installers for Worcester Bosch we can offer extended warranties for all Bosch Boilers installed. 

Will Replacing My Gas Boiler Result In Cheaper Gas Bills?

When upgrading your current gas boiler for a new condensing model you can expect some saving on your annual gas bill, however this is dependent on a number of variants with the most important being boiler efficiency. Below we have put together a likely cost saving related to upgrading to a new high efficient condenser model. 

If you opted to for a gas boiler upgrade with a minumum effieceny value of 90% costing €1968.00, these are the savings to be expected. You can further increase your annual fuel savings with energy saving control measures and increasing your home insulation value. 

Efficiency of your old boiler  Annual saving on your gas bill in %  Annual saving on your gas bill in €  How long it will take for your boiler to pay for itself 
60%  33%  €270 7.6 years

When To Get A New Gas Boiler 

Now you know the cost saving benefits you get with replacing your old-fashioned boiler with a new condensing model, but can't decide when is the right time to make the investment. Below we have put together some pointers that can help you with your decision. 

  • If your gas boiler is over 15 years old it may be time for a replacement. Efficiency levels decline with age, and may be as low as 60% or even lower. This means for every 100-euro spent on heating bills only 40 euro is effectively wasted. 
  • If you are unlucky enough to have had your boiler breakdown and it is not cost efficient to repair. If you have had a qualified registered gas installer out and you have been told it's no longer feasible to repair it is time for a new boiler. 
  • If your current boiler has a pilot it may be worth replacing, the constant pilot required is wasteful of gas. 
  • If you currently have a gas fired back boiler or floor mounted model, these boilers are not considered to be very efficient and replacing may make financial sense.  
  • If you gas boiler has a rather large box type flue, these older boilers are very wasteful of energy. 
  • If you have had a qualified register gas installer declare your boiler unsafe. 
  • If your gas boiler has an energy rating of G or Lower. 
  • If you are considering upgrading your current heating controls, it may be worthwhile to upgrade your gas boiler too. Currently there are grants available to home owners through the home energy scheme. 
  • If you are carrying out extensive renovation it makes sense to upgrade your central heating, controls and boiler.
