What kind of boiler do you have?

Take a good look at the boiler you have and the heating system already installed. But not knowing which boiler you don't have is not surprising. It is likely to be one of three types below:

Combi boiler

Boiler with tank

Back boiler

If the boiler heats hot water for immediate use and there is no hot water cylinder, it is most likely a combi system. If there is a cylinder for hot water and a tank for overflow that is probably in an attic, then it is probably a low pressure gravity-fed system. High pressure, or unvented, system produces water at mains pressure and is the least common of the three options.

Should I replace my boiler?

We have listed some of the reasons why you should replace your gas boiler with a new one. This may be for different reasons such as breakdowns, energy savings or due to established regulations.


By breakdowns:


Due to energy savings: The new gas boilers on the market have higher performance and save on gas bills thanks to their technology.


By regulations: Take into account the established European regulations, your boiler may not meet the requirements and you should change it. Boilers installed 10 years ago are no longer allowed by the European regulations due to their low performance and high emission of polluting gases.

How often should I change my boiler?

The average time to change the boiler is between 10 and 15 years.

Q: What kind of fuel does your boiler use?


If your boiler is more than 20 years old, it is necessary to make a change even if it works correctly. The repairs of this type of boiler are not usually profitable since the parts are not found and the fixes are not durable over time.


If you have a boiler that is more than 15 years old, its operation is not entirely optimal and neither is its energy efficiency. If your boiler is over 10 years old, it means that its life is over. If there is some kind of malfunction in your combi, it would be correct to replace it.

Advantages of replacing your old boiler

Condensing boilers are the most efficient on the market, being respectful of the environment and providing lower gas consumption in heating and hot water installations.


Replacing the boiler is necessary for a newer and more advanced combi with high efficiency. Buying a new boiler gives you the following main advantages:



The best time to change the boiler is in summer, since in this period when the heating does not need to be turned on and hot water is not as necessary as in winter.

Boiler replacement cost

The replacement or installation of the new boiler for heating should be done at home every 10-12 years. The new boiler system you purchase from Zara Heating will both reduce your gas bill and make it possible for you to heat more efficiently. 


When buying a boiler, you should not forget that the price reflects its characteristics and energy efficiency. It is normal to think that some gas boilers are expensive only because of the brand or the manufacturer. However, the truth is that behind the price of a gas boiler there are benefits such as power, efficiency, safety, durability.
