Air source heat pump (ASHP) works by transferring heat absorbed from the outside air to an indoor space, such as a home or an office via wet central heating systems to heat radiators or underfloor heating and provide domestic hot water. Heat pumps work similarly to a refrigerator they absorb heat and transfer it to another medium.

Aluminum radiators are an ideal choice when looking for high outputs in both high and low temperature heating systems. Aluminum radiators respond instantly to changes in temperature, heating up much faster than standard steel radiators, thus enabling you to regulate your room`s temperature more easily

Prevents ice from forming at the bottom of the drain pan with a heating pipe.

Biofuels are a renewable energy source, made from organic matter or wastes, that can play a valuable role in reducing carbon dioxide emissions.

Biomass boilers provide you with space heating and hot water for the entire home,but instead of using gas or oil to produce the heat, they combust sustainably sourced wood pellets.

Condensing oil boilers feature a heat exchanger that gives them a very high efficiency. They extract nearly all of the heat contained in the flue gases ,turning this into additional heating energy and therefore minimising waste.

A carbon footprint is the total amount of greenhouse gases (including carbon dioxide and methane) that are generated by our actions.

Carbon is a chemical element with the symbol C and Atomic number 6.  It is nonmetallic and tetravalent-making four electrons available to form covalent chemical bonds. It belongs to group 14 of the periodic table. 

This is two separate thermostats - a control thermostat and an overheat thermostat, built within a single unit. The control thermostat allows the operating temperature to be set, whereas the overheat thermostat is a safety device that will operate if the temperature goes beyond the pre-set limit. The overheat thermostat can be manually reset at the touch of a button, once water temperature has cooled down. 

With a deep retrofit, you undertake an extensive overhaul of your heating systems that can save you over 60% on your energy costs. 

Hot water for the kitchen and bathroom sinks, tubs and other appliances in your home.

The Energy Related Products Directive is designed to assist the EU achieve reductions in carbon, NOx and SO² emissions.

This is the relationship between energy supplied to the boiler and energy output from the boiler.

An approach to reduce energy consumption, while continuing to maintain a certain level of energy output.

Fan convectors radiators are fan-assisted heat emitters which use Low Temperature Hot Water from a heat source to heat up a heat exchanger. The fan then blows the heated air into the room to heat a space quickly and efficiently.

The Sustainable Energy Association of Ireland (SEAI) offers financial grants to Irish homeowners for upgrading your heating system, installing an air source heat pump and replacing your oil boiler. Find out more about these grants here: https://grantengineering.ie/support/government-incentives/  

Allow you to easily regulate the temperature of your home based on settings input by the user to ensure maximum comfort.

A heat pump is a versatile electrical appliance featuring an efficient heating system which extracts heat from one source and transfers it to another, working like a fridge and an air conditioning unit.

Home heating provides warmth to the number of spaces within a building and optionally also able to heat domestic hot water from one main source of heat.

The Home Heating Appliance Register of Performance (HARP) database is a product efficiency database for home heating appliances used in Ireland.

Insulation is a thick layer of a substance that keeps heat retained within each room in your home.

The kilowatt-hour is a unit of energy equal to one kilowatt of power sustained for one hour or 3600 kilojoules. It is used as a billing unit for energy delivered you electrical items.

Is a control centre that controls how water is distributed to parts of the house. 

The gateway to the Neo System, providing remote control of the Neo System from IOS and Android mobile apps. 

Is the thermostat that works within the the neoSystem.

The app that works seamlessly with the neoSystem. 

The heating controls system that works effortlessly with the Grant Afinia aluminum radiators and Grant Uflex underfloor heating. 

NZEB Nearly Zero Energy Buildings was introduced into the 2010 revised version of the Energy Performance of Buildings Directive, Nearly Zero - Energy Buildings means a building that has a very high energy performance.

An oil boiler works in a very similar way to a gas boiler. The fuel in this case oil is ignited in the combustion chamber and a heat exchanger warms up cold water, either from the mains in a combi system or from a cold water tank in a conventional system oil is a more efficient fuel than gas.

Is a subsection of general building regulations that relates to the conservation fuel and energy that was created in 1997, with the latest amendment occurring in 2017 to reflect the requirements of the European Energy Performance of Building Directive (Recase) in relation to the requirement that all buildings be Nearly Zero Energy Buildings (NZEB) by 31st December 2020.

Is the independant, international approval award programme associated with the UK Noise Abatement Society charitable foundation. 

Is a HFC refrigerant, used as a replacement for R410A in low temperature refrigeration and air conditioning applications.

A type of heat emitter. Grant offers a variety of radiator options to heat your home. You can view the range here: https://grantengineering.ie/products/afinia-radiators/

Solar thermal energy is a form of energy and a technology for harnessing solar energy to generate thermal energy for use in industry, and in the residential and commercial sectors.

Underfloor heating is a form of central heating that achieves indoor climate control for thermal comfort using hydronic or electrical heating elements embedded in a floor. Heating is achieved by conduction, radiation and convection.

Under floor heating (UFH) can be a means to simply warm your floor or act as a primary heat souce replacing your radiators.

The Grant Vortex condensing oil boiler range comprises of the most efficient and reliable oil fired boilers in Ireland. Our condensing boiler range is available in 63 models with outputs from 12 – 70kW. View our range here: https://grantengineering.ie/products/oil-fired-boilers/

Is a smart control system that reacts to internal and external temperature changes which can match a heat output closer to the needs of the home.

This is the result of no carbon being emitted into the atmosphere.
