Gas Boiler

When choosing a new boiler, you must take into account the following factors:

– the type of fuel
– the efficiency
– the combustion system
– the space available in your home
– your hot water requirements
– boiler warranty (most gas boilers come with a warranty between a 2 – 7 year periods Depending on the manufacturer) once annual servicing is carried out.

You may think that requesting a bigger boiler might give out more heat, but a larger boiler will still only generate the same heat but less efficiently.

Every type of Boiler loses efficiency with every passing year. When replacing your boiler, you should see savings from 30-50% on your bills as an older boiler takes more power to generate energy.

When you need to change your current boiler it is important to establish the current heating system you have and the type of boiler you are looking for. There are two types of domestic boilers as explained below.

 

A Condensing Combination boiler or Combi Boiler:

This is a compact unit suited to heating smaller homes that do not have a high demand for heating and hot water. Everything that the boiler needs is built into the unit which means there is no need for a separate hot water cylinder or cold-water tank in the home. A combi boiler takes care of both your heating and hot water, heating and hot water are controlled separately so there is no longer the need to fire up the whole system just to get hot water, it draws water directly from the mains and passes the water through a heat exchanger, which gives you instant mains-pressurised hot water to a tap, shower or Bath.

A Condensing System needs a hot water cylinder tank normally found in the hot press.

Most boilers these days are now condensing types.

Condensing boilers are also known as high efficiency boilers and can achieve in excess of 90% efficiency. If your boiler is older than 10 years old it could be operating at as low as 60% efficiency, meaning that for every €100 you spend on €40 could be wasted.

As boilers work to heat your home, waste gases are produced which are then emitted out into the atmosphere. These waste gases carry heat which is then lost, so your home isn’t benefiting from some of the heat being generated by your boiler. To combat this and get your boiler performing more efficiently, condensing boilers are fitted with 2 internal heat exchangers to ensure that less heat is lost. Thanks to this, the boiler doesn’t have to work as hard and uses less energy.

We recommend a boiler that is compatible with a heating app. This means you can control your heating and hot water remotely, via your phone, tablet or computer- no more timeclocks. Separate heating zones are set up so rooms that only need heat at certain times can be programmed which will save money.
