One of the most desirable benefits of Air to Water Heating systems is they use a FREE energy source (AIr) to power your heating system, so there are no more ‘gas or oil bills to pay!
Air to Water heat pumps work by extracting heat from the air outside and transforming this into ‘useable heat’, which is then used to heat your home, and your underfloor heating as well as giving you plenty of hot water, whenever you want it.
Air to Water heating systems is the most modern and efficient way of generating a constant comfortable temperature in every room of your home as well as producing constant hot water.
This is a renewable heating technology that offers a highly efficient home heating system, so you no longer need to use fossil fuels all while eliminating gas and oil bills.
Air to Water heating systems are a type of heat pump that use small amounts of electricity to extract heat from the air outside, even on a cold day, and transforms this into usable heat inside your home.
This happens with the help of an indoor and outdoor unit, using a refrigeration-type process along with a compression cycle. A bit like a fridge but in reverse!
The Heat Pump is located outside the home, and the heat pump’s indoor unit is connected to the water storage tank, which circulates the hot water through the heating system.
This will heat radiators, giving you a consistent cozy temperature in every room of your home, plenty of hot water and it can also run your underfloor heating.
Conventional heating systems, such as gas or oil boilers, cannot produce more heat than that which is contained in the fuel they use … HOWEVER … a Heat pump can produce 3 to 4 units of heat for every unit of electricity consumed, making them one of the most highly efficient heating systems available.
The efficiency of Heat Pumps is typically measured by the ‘coefficient of performance’, referred to as (COP). The ‘COP’ is the ratio of the amount of electricity used by the heat pump to the amount of heat it transfers. For every kilowatt of electrical power a heat pump consumes, it can actually produce 3 or 4 units of heat.
If a Heat Pump has a COP of 4, (see pump specifications) it means for every unit of electricity used by the heat pump, 4 units of heat are transferred, so this means Air to Water heating systems can be up to 400% efficient.
Compare this to conventional heating systems such as gas or oil boilers, which have a COP of around 0.8, which results in an efficiency rate of just 90 % approximately.
The efficiency of a gas or oil boiler is typically measured by the annual fuel utilisation efficiency (AFUE) rating.
The AFUE is a measure of how much of the energy in the fuel source is converted into ‘usable heat’. An AFUE of 90% means that 90% of the energy in the fuel is converted into usable heat, while the remaining 10% is totally lost through various processes. So you can imagine the savings when you switch to using a Heat Pump instead.
The SEAI offers a grant for Heat Pump systems as well as grants for central heating systems for Heat Pump and heating controls.
To qualify for the SEAI heat pump grant your home must have a ‘low heat loss’ factor to ensure your heat pump can meet the heating and hot water demands of your home, and work efficiently, so certain criteria need to be met in order to qualify for the SEAI Grant.
A technical assessment is required to ensure the heat pump is the correct size and capacity for your home and to ensure it is designed correctly to meet 100% of the home heating demand and at least 80% of your hot water demand.
As Air to Water Heat pumps work best on well-insulated homes, and work much more efficiently at a lower temperature than a standard boiler system, you may need to invest in some fabric upgrades to meet the required ‘heat loss indicator’ to ensure your heat pump is a success.
It is possible to use an existing water tank with a new air-to-water heat pump. However, the condition, compatibility, and size of the tank need to be taken into consideration.
If the existing tank is in good condition, is the correct size, has good insulation, and is compatible with the heat pump’s flow temperature, then it can be used. If not, a larger, more efficient tank would be recommended.
Air to Water Heating systems can be used in combination with existing radiators, however, if they are found to be unsuitable, upgrading some or all of your radiators may be required.
Yes, air-to-water heat pumps can be used to create hot water for showers and other household uses. The heat pump produces hot water by extracting heat from the air outside and transferring it into a water supply. This hot water can then be distributed throughout the home and used for a variety of purposes, including showers, washing machines, sinks, and other household requirements.
It’s important to note the capacity of the heat pump to produce hot water will largely depend on the size of the heat pump, and the hot water demand of the individual household. So it is very important to install the correct size heat pump for the home.
Air to water heat pumps is relatively low-maintenance systems. It is advised to service the system regularly. With proper maintenance, an air to water heating system can last up to 20 years or more.
Yes, Heat pumps work in cold weather. They are well suited to the Irish climate, even on cold days. Understandably, heat pumps need to work a little harder in cold weather to extract the heat from the air, but are designed to do this even at low temperatures, so they can transform this into usable heat inside your home.
