If you have an old boiler, then you are most likely thinking about replacing it. A new boiler costs several thousand euros, however, so many homeowners may doubt the appropriateness of an upgrade.
But what if we told you that a new boiler can offer dramatic improvements in your budget management, home safety, and convenience? If you have a 10-20 years old gas or oil boiler, then an upgrade could significantly improve the quality of your life.
In this material, we are going to provide you with top reasons to replace your old oil boiler or replace the old gas boiler. If you have an ancient boiler, then you most likely will want to replace it after you are done with this post.
Top Reasons To Replace Your Old Gas Or Oil Boiler With A New One
In this section, let’s have a look at the top 6 reasons to replace your old gas or oil boiler. These reasons are:
- Increased efficiency.
- Improved safety.
- More reliable operation.
- Low maintenance costs in the long run.
- Space savings.
- Compatibility with solar power.
- Better, more convenient controls.
Efficiency improvements are the biggest reason to throw your old boiler away and install a new one. You could expect to be saving up to 20%-25% annually with a new boiler!
The primary reason for the dramatically increased efficiency is technological advancement. Particularly, modern condensing boilers are far more energy-efficient than their non-condensing predecessors.
Introduced way back in the 1980s, condensing boilers could boast around 90% energy efficiency, whereas non-condensing boilers go only up to 75%. The 75% applies to any non-condensing boiler, whether new or old.
For the purposes of this material, you don’t need to understand why exactly condensing boilers are more efficient. Accept higher efficiency as a fact.
Although condensing boilers are 30-40 years old, they haven’t seen widespread use before the 90s due to reliability issues. So if your boiler has been bought back in the 80s-90s, you probably have a non-condensing unit.
Aside from technological advancements, old boilers may actually become less efficient over time. If you have a decade-old boiler, then you are most likely getting much lower efficiency than when it was brand-new!
New boilers are considerably safer than old ones as well.
Old boilers typically have an open-flue design. In these boilers, the air is drawn into the boiler from the vicinity of the boiler. The gas is combusted, and waste is discharged outside.
The downside of open-flue designs is that they may allow some amount of carbon monoxide inside your property.
In contrast, modern boilers are sealed. Air for combustion is drawn through the flue and then is ejected back out. No toxic gases will make it into your home since the boiler is sealed.
These differences in design make modern boilers much safer in operation. If improved efficiency wasn’t enough for you, then perhaps better safety will be a strong reason to replace your old boiler.
Not sure what type of boiler you have?
If you don’t know the type of your boiler, then follow these tips to identify it:
- If you’ve installed the boiler more or less recently (within the last 6-10 years), then it’s most likely a condensing boiler.
- If the flue is metal, then your unit is probably non-condensing. Condensing boilers typically have plastic flues.
- If a plastic pipe comes out of the bottom of the boiler and goes into a drain, then it is a condensing unit.
The third important reason to get rid of your old oil or gas boiler is reliability.
With regular maintenance, even ancient boilers can stay fairly reliable throughout the years, requiring minimal maintenance. However, not everybody is meticulous or knowledgeable enough to keep an eye on their boilers.
If your old boiler is breaking down often, then you should definitely replace it. The longer you wait, the more time and money you will have to waste trying to make your boiler serve you longer.
Do yourself a favor and purchase a new boiler – your wallet will be very grateful!
Low maintenance costs over the long run
Needless to say, if your boiler breaks down often, then you will need to spend more money on getting the unit up and running. Not only that but finding details for an old boiler may become extremely challenging.
The costs of rare details could be astronomical as well, making repairs and maintenance a wallet-hungry procedure.
A new boiler would be much more cost-efficient over the long run by requiring less maintenance. Even when a new condensing unit does require maintenance, it probably won’t cost a whole lot.
Older boiler models are typically floor-mounted, which means that they consume considerable space in your home. With that, getting yourself a new boiler allows you to:
- Free up some areas for other items.
- Just make your home a little more space-efficient.
Modern boilers are predominantly wall-mounted, so they do not occupy floor space. Now, new boilers do require quite a lot of wall area, but we think that floor space is going to be more valuable for most homeowners.
Compatibility with solar power
With some fiddling, you can connect solar panels to any appliance that requires electricity. However, modern boilers make the transition to solar energy much easier. So modern boilers are energy-efficient not only by themselves but also by allowing you to make use of solar energy.
And the final reason for replacing your old oil or gas boiler is controls. Modern boilers have a bunch of features to make control and adjusting more conveniently. If you purchase a mid-end boiler now, it will most likely have:
- Smart features.
- A wider range of settings for adjustment.
- More convenient controls.
Of these, smart features are probably the biggest reason to replace your old boiler. Smart-enabled boilers deliver the following two benefits:
- They allow you to manage your heating schedule by the minute. Ultimately, this means that your home is heated only when necessary, which translates to cost savings over the long run.
- You may control smart boilers remotely via Amazon Alexa, Echo, or other compatible smart home assistants.
How Much Does A New Boiler Cost?
If our reasons have convinced you that your boiler needs to be replaced, then you might be interested in how much a new boiler will cost.
Well, this depends on the boiler model. But generally, expect to pay 2000-3000 euros for the installation of a new boiler.
Now, this is a lot, but you should actually be able to bring all this money back thanks to the improved efficiency of modern boilers. It will most likely take you a few years to break even, but it’s better to spend money now to get the chance to save money tomorrow than be stuck with an old, inefficient unit.
Energy Homes grants can help you save money with heating upgrades
If you have an old boiler, then you also most likely have inadequate insulation or really old heating controls. These all should be replaced for the same reasons we gave above.
But needless to say, if you have to replace a lot of stuff at once, you will need to take a few thousand euros out of your wallet.
Well, the Sustainable Energy Authority of Ireland offers grants to help owners of old homes upgrade their heating systems. There are some conditions that you need to meet to be eligible for the grant:
- For insulation and heating control system grants, your dwelling must be built before 2006.
- For heat pump and solar thermal grants, your dwelling must be built before 2011.
- You must use the services of an SEAI-registered contractor.
- You must use newly fitted materials and hardware.
- The work done must comply with required standards.
- After the work is done, an SEAI-registered assessor needs to evaluate your BER (Building Energy Rating).
Among the upgrades that grants are provided for are:
- From €400 to €6000, depending on the location of the insulation.
- Heat pumps. From €600 to €3500, depending on the heat pump type.
- Heating system control upgrade. €700.
- Solar water heating. €1200.
No grants are provided for boilers, so you’ll still have to invest in one from your own pocket. But if you have to perform large-scale upgrades, then why not make use of the SEAI grant to save money?
How Often Should A Boiler Be Replaced?
Some of our readers may wonder how often boilers should be replaced. Well, there is no universal answer to this question, but generally, a boiler should be replaced every 10-15 years.
With that said, if you have an old boiler, you don’t necessarily have to replace it. If it works reliably, is convenient enough for your needs, and your energy bills aren’t too heavy on your wallet, then you may not have to upgrade your boiler right now.
If you are concerned with the safety, reliability, or efficiency of your boiler, then do replace your old gas boiler or replace the old oil boiler. A new boiler will cost a lot, but in the long run, it will bring the investment back and will even save money!
