Boiler Replacement: What Costs Should You Calculate?

Household appliances don't last forever, which also applies to larger ones. A hot water storage tank in the heating system rarely needs to be replaced. The situation is quite different for the boiler. We wanted to determine what costs can be expected for a replacement from Zara Heating's experts.

Replacing an old boiler allows both to gain comfort and save money on your energy bill. Over the years, the equipment evolves and becomes more and more efficient while consuming less.

Not every old boiler necessarily has to be replaced. But in which cases is a boiler replacement necessary? Should I wait until my heating finally stops working, or does it make sense to act beforehand?

When Should You Replace Your Boiler?

Suppose your existing boiler is only a few years old. In that case, it probably does not necessarily need to be replaced because it is technically not so outdated that extreme energy losses occur during combustion. The situation is different, of course, if the existing heating system is not very old, but expensive heating repairs are imminent. A comparison should be made as to whether a boiler exchange would not make more sense in this case. Because of this, one secures at the same time a significantly higher efficiency, thus lower energy costs and a lower environmental impact.

Suppose the boiler is more than a few years old and the building is more than 25 years old. In that case, you cannot avoid replacing your boiler in the long term, even if it still works perfectly, because the constantly rising heating costs are not doing you any favours in terms of energy costs for the future.

The initial investment costs for a new heating system often pay for themselves after just a few years due to the savings from lower operating costs. We have listed a few indicators that it is time to replace the current boiler.
Your Boiler is Worn or Outdated
The average lifespan of a boiler is 12 to 15 years. However, it is not uncommon for a boiler to operate without too many problems well beyond this time. Deterioration and wear lead to a loss of performance and an increase in consumption that can reach 20%. If your boiler is over ten years old and non-condensing, it's probably time to consider buying a new model.

Avoid Breakdown Fees

Having your boiler regularly serviced by an authorised specialist will prevent malfunctions and other unpleasant surprises. However, your boiler will not stand the test even with periodic maintenance. If it frequently displays error messages or is subject to recurring malfunctions, your boiler is probably close to obsolescence. In addition, a breakdown almost always occurs unexpectedly, and repairs generally generate substantial costs.

When you plan to undertake renovation work, give heating the importance it deserves. The main item of residential energy consumption, heating, represents a significant percentage of a household's energy expenditure.

Prefer Clean Energy

New generation boilers are not only advantageous in terms of energy costs but also for preserving the planet. Under the European Ecodesign Directive, only condensing boilers meet central heating standards.

Compared to a high-efficiency or low-temperature boiler, a condensing boiler offers around 10% higher efficiency. Compared to a conventional atmospheric boiler reaching the age limit, this percentage can rise to 35%. A new generation gas boiler can achieve an efficiency of 111%. This is because the European directives do not consider the heat losses of the flue gases.
Old Boilers are Expensive and Polluting Appliances
Turning to devices that use less fuel or renewable energy is recommended to save money. Changing from an old generation oil or gas boiler to a high-energy performance boiler has the advantage of better respecting the environment. These new appliances consume less and thus emit less CO2 into the air.

The Dilemma: New Boiler or Technical Service?

And now the big question you are surely asking yourself is shall I fix my boiler or repair it?

It is difficult to answer because it depends on each case. Experience tells us that it is convenient to start thinking about changing it after ten years because it has a much lower performance. As said before, we recommend changing the boiler before the age of 15, and this is important in terms of its useful life.

As for breakdowns, it will depend on the type of failure and its costs. Generally, a boiler that gives many problems throughout the year is not usually profitable. Problems and repair costs may increase.

Also, remember that there will come a time when it is not easy to find spare parts for your old boiler. And that, beyond being an economic nuisance, can also give you more problems if the breakdown occurs in the middle of winter with freezing temperatures outside.

What to Consider When Replacing a Boiler?

The majority of heating systems are more than 25 years old and are therefore technically more than outdated. If you also have one of these, your heating system does not use a condensing boiler.

This is not up to the latest standards and enables the exhaust gases produced by combustion to be used again to generate heat. If you would like to replace your old oil or gas heating system with such an efficient model, there are a few things to consider.

In most cases, the chimney must be prepared for the operation of a condensing boiler, which results in additional costs because such a boiler uses water vapour condensate from the exhaust gas of the thermal bath to generate heat. A unique stainless steel chimney is required for this.

Replace Hot Water Tank in Heating System

The costs of replacing the hot water storage tank initially depend on the storage capacity. The required storage capacity can be easily determined based on the number of people in the household: around 30 to 50 litres of storage capacity are needed per person. Depending on the required litre, the cost of a hot water tank will vary.

Q: What kind of fuel does your boiler use?

The boiler is a water heater, not a hot water tank. The acquisition costs for an electric boiler are usually between £1,500 and £3,500, for a gas boiler around £500 and £2000.
