Heating Systems.

Kingdom Installation Insulation Kerry Ireland

An Air to Air Heat Pump system takes the heat from the air and boosts it to a higher temperature using a heat pump which is usually placed outdoors at the side or back of a property. This warm air is circulated by fans to heat your home. They are ideal where there is no existing wet heating system in place, such as apartments and older houses. Benefits include lower fuel bills, easy installation and minimal maintenance.

An Air-to-Water Heat Pump system can replace your existing oil or gas boiler and provide heat to your existing radiators and hot water systems. An Air-to-Water system has an efficiency of approximately 360% compared to 92% of a modern oil or gas boiler. An average performing Air Source Heat Pump in an average four bedroom detached home could save:

Between €450 to €700 a year if replacing an oil boiler (non-condensing)
Between €1,400 and €2,000 a year if replacing an LPG boiler (non-condensing)
Between €900 and 1,500 a year if replacing electric heating (old storage heaters)

Gas and Oil Boiler Upgrades.

Most old gas and oil boilers are regular boilers that have a separate hot water cylinder to store hot water, rather than providing it directly from the boiler. When you replace your boiler you can buy a new regular boiler, and keep your hot water cylinder, or buy a combi boiler that doesn't need a cylinder. A regular boiler is more efficient than a combi at producing hot water in the first place, but then some heat is lost from the hot water cylinder, so a combi may be more efficient overall.
