Why you should upgrade your Oil Boiler

Upgrading to a Condensing Oil Boiler can result in significant savings not just financial but in CO² emissions as well.

Even the best oil boilers require replacement approximately every 15-20 years. Even if you have had your boiler regularly serviced it will still undergo general wear as with any equipment with moving parts. Also, within its lifetime there will have been many engineering improvements and updates which in general help make boilers run more efficiently.

Alternative Energy Ireland install Grant Engineering condensing gas oil boilers. These boilers have a great reputation and experience of boiler applications in Ireland. Grants have the highest efficiency oil boilers available in the Irish market and also have a full range of SEDBUK “A” rated condensing oil boilers.

Sustainable energy authority of Ireland

Avail of a significant grant when you upgrade your Oil Boiler

SEAI are offering grants of €700 to everyone upgrading their heating controller along with their high-efficiency oil boiler. To receive this grant, you need to install the high-efficiency boiler, upgrade your central heating controls and have a BER cert issued for your home after the works are complete. We can easily perform all this for you in two days. Know more about the oil boiler grants.

Grant are one of Ireland’s and the UK’s leading manufacturers of quality high efficiency oil-fired boilers. The company has built its reputation over many years for reliability and excellent levels of after-sales service. Efforts to safeguard the environment by reducing domestic levels of energy consumption have led the company to design their unique range of ultra-high efficiency Vortex oil boilers.

Zoned Heating System

Should I get a multi zone heating system or 2-zone heating system?

There is a lot of talk these days about a zoned heating system. You may be wondering how this “zoned” heating system differs from a standard heating system. You need to think of a typical standard heating system as one circuit, or “zone”, with one controller, one set of pipes all linked and a pump; and when the system is turned “on” all the pipes gets hot water sent to them and all the radiators heat and the hot water cylinder heats to whatever temperature the boiler is heating to.

If your heating system has 2 zones the piping to the cylinder and the radiators is in two separate circuits, or “zones”. Therefore, you can heat all the radiators OR the hot water cylinder zone separately, or both at the same time. This is especially convenient in the summer when you do not wish to heat your radiators but still require hot water.

However, with our smart heating controls, we can give you as many zones as you wish, with none of the mess. You can have the open plan diving kitchen area as a zone, the bathrooms on a separate zone, the kids play room on a zone and all the bedrooms as their own zones. Each zone can be heated by itself and to different temperatures at different times of the day. This is all done from your phone in a very easy to use app and everything is flexible. please use our online cost calculator for condensing oil boiler prices in Ireland.

Flexible heating zones?

Yes, when your house situation changes, we can adjust your zones to suit.

Let’s take the home office as an example. In early 2020 lots of houses had to find space for a home office. The spare room, now becomes a home office. We can then heat your home office to 21 degrees from 9am to 5pm Monday to Friday. We can also set our smart controls to heat your kitchen for an hour at lunch time. When rads are off in areas that heat is not required, you’re saving money.

When kids move out of the house, we can set our smart heating controls to keep a low level of heat in the kids rooms all week, but when they come to stay, we can heat the rooms as normal.

Towel rads can have their own zone, so that you have warm, dry towels all year round.

If you go away on holiday, you can set your heating system to keep the house at a mild 10 degrees so that you don’t need to worry about pipes freezing or mould forming. Then, the day before you come home, you can revert the controls back to normal.

You can decide to move a rad from one zone to another, you can do this yourself or we can do this for you for the lifetime of your system as it’s all accessible remotely.

You can also control your lamps and other electrical devices from our smart heating system app.

Grant Efficient Heating Solutions


The Vortex range of domestic boilers are extremely high efficiency condensing oil boilers and are all independently certified to SEDBUK Band “A” and “B”. The incredible efficiency of the boiler enables Grant to lead the way by constantly looking for ways to increase the efficiency of their oil boilers. The incredible efficiency of the condensing boiler is due to the development of a single boiler unit with its two unique heat exchanger units. This additional surface area aided by the unique patented baffle design, increases the amount of heat extracted from the combustion process and thus reduces the heat wasted to the atmosphere. So much heat is extracted from the combustion gases that their water vapour element condenses into liquid form, releasing the latent heat that was used to create the vapour in the first place.

It is this heat gain that gives the condensing oil boiler its significant advantage over a non-condensing oil boiler and results in it using less fuel and having lower running costs. Because of their increased efficiency the Vortex series emit less carbon dioxide than all other domestic condensing boilers, which will contribute to efforts of reduced global warming.
