What do I need to know about Heating??


 Air to water (or Air Source) heat pumps utilise energy in the outside air and transforms it into usable heat. This is performed through a refrigeration process and a vapour compression cycle, which sounds very complicated, but it’s basically how a fridge works, but in reverse.

Heat pumps work much more efficiently at a lower temperature than a standard boiler system would.  An air to water heat pump extracts heat from the outside air in the same way that a fridge extracts heat from its inside. It can get heat from the air even when the temperature is as low as -15° C.

This makes them very suitable for underfloor heating systems or larger radiators, which give out heat at lower temperatures over longer periods of time.

An underfloor heating system circulates low temperature water. Most conventional heating systems circulate higher temperature water, usually between 50ºC to 80ºC whereas an underfloor heating system circulates water between 25ºC to 40ºC.

An Air to Water heat pump is the most modern and efficient way of generating this low temperature supply of water.  A heat pump is the most efficient way of heating your home and your domestic hot water requirements for Irish climate conditions.  Air to Water heat pumps also dramatically reduce CO2 emissions and carbon footprints.



Steel versus Aluminium Radiators, which should I choose?

 Aluminium conducts up to 5 times more efficiently than steel meaning two things, your rooms will warm up faster, and also cool down quicker due to the metal reacting to dialling up or down of the thermostat more quickly. This can also reduce energy use resulting in savings on gas, electricity and water bills. Steel, on the other hand, retains heat far better than aluminium, so your rooms will stay toasty for longer after the central heating goes off. This, unfortunately, does mean that your radiator will take longer to heat up, so the choice you make depends on the purpose of the radiator in your home.   Aluminium is by far more eco-friendly than steel, it not only uses less energy to produce the raw material, but it also uses less energy and water to heat the radiator. This makes it better for yourself and the environment as you could save money on your bills as previously mentioned. Aluminium is also 100% recyclable and is often made from recycled materials making it more beneficial to the environment in the long run. Having high BTU output, aluminium radiators are winners for the environment, but they also have the highest price.  In summary, aluminium radiators will cost you more to buy and the choice of colours and design can be seen as limited. Despite the drawbacks, they are a more environmentally friendly radiator and are less expensive to run saving you money in the long run. Steel radiators offer almost the opposite of aluminium. They are less expensive at the outset, come in a vast range of shapes, sizes, colours and finishes and retain heat longer, however you don't benefit from the cost-saving aspects you would with an aluminium radiator.

What are the benefits to heating with wood pellets rather than gas/oil/electric heat?

There are several benefits of heating with pellets instead of other fuel types such as gas or oil. Pellets are clean burning, renewable, affordable, and available in most geographic locations. Pellets also give the smell and ambience of burning wood without the cutting, stacking, and splitting associated with logs, making pellets a more convenient option for homeowners.


Does a heat recovery ventilation system save me money? 

Heat recovery systems are designed to recover on average 90% of the heat normally lost through open windows, trickle vents and other break-out points i.e extractor fans. The systems will through time, off-set the heating costs and reduce energy bills, making it a worthwhile investment.

You could lower your heating costs by up to 30% against using window trickle vents and bathroom fans and improve the indoor air quality with fresh filtered air.
