When buying or renovating a home, it is important to know what types of boiler you can install. This will help you choose the one that best suits your home and your needs.

After all, the good life is also about feeling good at home.

Gas boilers

You could compare the operation of a gas boiler to that of an oven:

When we turn it on, the gas reaches the burner and combusts. The heat generated by this reaction then heats the water that flows through a pipe that reaches the burner.

The hot water then flows into the heat exchanger and heats another pipe, which is used for the domestic water that you will use in your home, distributed through a pumping mechanism to radiators and taps.

Gas boilers: advantages

This is why you will love gas boilers:

  • For larger houses and with a higher consumption of domestic hot water and heating, gas boilers are highly recommended. The supply is virtually guaranteed, as it is not subject to power outages or liquid fuel shortages.

    And, unlike electricity, which can be disrupted by storms or adverse weather conditions, gas travels through underwater and underground pipelines that are protected against these unforeseen events.
  • If the environment is high on your list of priorities, the good news is that gas boilers emit fewer pollutants than diesel-fired boilers. What’s more, they do not generate unpleasant odours or soot.
  • Added to this is the high efficiency of this type of boiler. More and more efficient models are being designed, particularly for condensing boilers, which use almost all of the heat they generate, in some cases reaching 90% efficiency.
  • Another good thing: natural gas is very cheap compared to other energy sources, especially oil.

Diesel-fired boilers

Diesel-fired boilers essentially differ in the type of fuel they use, which is liquid fuel instead of gas.

This fuel is stored in a tank and, from there, it is pumped to the combustion chamber. Once it reaches the combustion chamber, the fuel burns and transfers the heat to the heat exchanger, which then heats the water that will be used to supply the heating system and hot water taps.

Bear in mind that installing a diesel boiler is more expensive than other types of boiler, as it requires a tank for the fuel and, due to its weight, it usually requires several installers to get it up and running.

Diesel-fired boilers: advantages

Although diesel boilers are not as popular as they used to be, they still have certain advantages that should be considered:

  • Diesel boilers, especially condensing boilers, can reach higher efficiencies than gas boilers. Diesel boilers use almost all of the heat and gas that is generated by burning fuel, so they do not waste as much energy.
  • By installing your diesel boiler outside, you can save valuable space inside your home. You will also reduce any risk in case of leaks and you will not be disturbed by any noise caused by the boiler’s operation.
  • One of the major advantages of installing a diesel boiler is that you are not tied to a long-term contract with an energy supplier. You can buy and store diesel as you wish.

Especially if you have a large tank, you can buy it in bulk and reduce your costs even further.

Electric boilers

Electric boilers are becoming increasingly popular for small and medium-sized houses, as they do not take up much space and can produce enough hot water for heating and domestic use.

The way electric boilers work is very simple: they are connected to the mains electricity and cold water supply. When you turn on a hot water tap or switch on the heating, the boiler’s heating unit heats the cold water it receives from the mains. So the main difference with gas and diesel boilers is that electric boilers do not use any fuel.

Types of boiler

Electric boilers: advantages

  • As they do not require a tank and are small in size, electric boilers are cheaper to install. No ventilation duct is needed either, as they do not generate waste gases.
  • Electric boilers are very easy to maintain and do not require regular maintenance, unless there is a specific breakdown.
  • They are also very efficient. By not burning fuel, they do not lose energy through the waste gases they emit, reaching an efficiency of up to 99%. And because they don’t emit any waste gases, they have a much smaller impact on the environment. Great for reducing your carbon footprint. 😉
  • And they are safer, because no harmful gases such as carbon monoxide leak out, as could -though very unlikely- happen in a gas boiler.
  • An electric combi boiler is also a great option for homes that are not connected to the gas supply or do not have a lot of space for a tank.

Now that you have the information, it is time to choose. If you need advice or are looking for a new home in which to install one of these boilers, we look forward to seeing you at Sonneil.
