Replacing your boiler:

Our scope of work includes the installation of condensing boilers and renewable energy products from a range that uses the latest technology available. This may be as part of a fit out to a new or renovated property or it may be as a replacement. It has been demonstrated that modern condensing boilers improve efficiency to over 90% and we, at Coleraine plumbers, know this could save you up to 30% per year on your home heating bills. Obviously this will represent a big saving over the lifetime of your boiler.


We stress to you that whenever possible if you have an existing boiler we will try our best to ensure that it is running efficiently and effectively for you and carry out any necessary repairs or servicing. Sometimes however it becomes clear that you may need a new boiler in your home


In fact there are some indications that you might notice that your boiler is failing; before it completely stops:


1. Your boiler keeps restarting. This increases your monthly running costs to more than you were expecting.

2. Your boiler is having difficulty keeping your house and the water warm enough.

3. Your boiler is making noises!


The lifespan of a boiler can be hard to predict as it depends on the amount of use, its service history, the make and the model. Our best advice is to give us a call to come and check things out for you.


What you might be interested to know is that a new boiler may save you money!


It is in your best interests to install a boiler that is as energy efficient as possible. If you are a landlord this can be a good marketing point for potential tenants who will be concerned as to what the energy bills may be. With increasing energy costs year in and year out, this is becoming a priority for savvy tenants.


You should also be aware of the capacity of your boiler in that it should have enough capacity for your property. Small boilers may not fill a large bath, so be conscious of how many people live in the property and how many people the new boiler install is required to serve. Using an appropriately sized boiler prolongs the life of your boiler.


Moreover determining the correct energy needs of the boiler (e.g. kWatts for electric boilers) ensures that the flow rate is sufficient to circulate to all radiators. The higher flow rates help your boiler to heat the water faster.


When installing a boiler, we need to ensure it is well ventilated when fitted and we can advise you of the best position for a boiler. Be conscious also if a landlord that it is a legal requirement to fit a carbon monoxide detector by any boiler installation to protect the safety of your tenants.


Wall mounted boilers have replaced floor standing ones over recent years. Changing from a floor standing to a wall mounted boiler or repositioning your current boiler to a different room or wall may require extra work and cost. This will consequently add to the cost of the installation. Our engineers will advise on the best position for your new boiler and tell you if there will be any additional cost.


Something for you to consider is that there are different types of boiler:


You most likely have heard the phrase "condensing boiler" and that is because installing a high efficiency condensing boiler became a requirement under government legislation from 2005. That’s why the most modern boilers are therefore the condensing type.


What is a condensing boiler?


This is a boiler which requires less heat from the burner - so it is more efficient - they are better able to make use of the heat they generate from burning fuel - whether gas or oil.


A non-condensing boiler loses some heat in the form of hot gases released from the flue. A condensing boiler captures some of this heat and uses it to heat water returning from your central heating system.


A condensing boiler is fully sealed and takes air in directly from outside this makes them safer as there is a much lower risk of anything being sucked into the boiler and they are very energy efficient.


There are 3 main types of condensing gas boilers


Combi boiler

System boilers

Conventional (also called traditional, standard, regular or open vent)


Combi boiler - probably the best for most homes - they control both hot water and central heating and are very energy efficient. They heat hot water directly from the mains when a tap is turned on - thus you get unlimited hot water. They require no cylinder or water tank. You save space in your home and there is less installation time.


But - there can be some drawbacks - they are not great for low water pressure areas - and it's not possible to run two baths or showers at the same time - so they are not ideal for larger homes or HMO properties.


System boilers - can be good if you have more than one bathroom - they require a hot water cylinder but not a water tank. (both the pump and the expansion vessel are inbuilt) so there are no worries about frost damage or leaks from that. They are also compatible with solar thermal systems making them an energy efficient option


In terms of drawbacks these include finding the space for the cylinder and that you may have to wait for hot water to reheat if it runs out.


Conventional boilers - these are comprised of both a cylinder and a water storage tank. They can supply large volumes of water to multiple bathrooms - and are suitable for homes which already have traditional heating systems in place as the pipework may not need changing. They can also be used along with solar heating systems.


Drawbacks are that hot water isn't available on demand - and they are not a compact option. The requirement for both a cylinder and a tank can make the installation more complicated and therefore expensive (if starting from no system)


What type do you need?


Well that depends on your heating requirements and your hot water requirements - generally tank based boiler systems are best if a property has multiple bathrooms while combi boilers are likely the best for smaller homes with one bathroom.


Choosing the right boiler depends on different factors, for example, whether having gas connection or using oil, the hot water requirements in the home, the available space and the efficiency of the boiler.

To replace your old boiler with the same model is always easier, but the advantages of a newer and more energy efficient model is many cases outweighs the disadvantages of an old one.


Because of safety measurements, by law, a Gas Safe registered engineer must conduct boiler installation. Without the required qualifications, one may put one’s home or family at risk, which must obviously is something you want to avoid.
