An air to water heat pumps system consist of four major elements that allow the refrigerant to pass from the liquid state to the gas: a compressor, a condenser, an expansion valve and an evaporator.
1. A fan passes air over the evaporator, the refrigerant absorbs heat from the outside air. The refrigerant boils and evaporates at a low temperature giving us vapour.
2. The vapour passes into the compressor and compression increases the temperature.
3. The warm vapour is condensed is the heat exchanger and the rejected heat is passed onto the heating and hot water system
4. The condensed vapour returns to liquid, passes back through expansion valve, reducing pressure and temperature, ready to start cycle again

New build & retrofit applications
Daikin’s versatile heating range fulfils all your needs, whether you are renovating your home or involved in a new build project. Whatever the age of your property, you can depend on Daikin’s heating and cooling solutions to last for many years to come, providing reliable service whatever the weather.
The Daikin Altherma low temperature air to water heat pump system is a perfect heating and hot water system for any new build project. This low temperature system is a perfect combination for underfloor heating, low temperature radiators or fan coils. The integrated indoor floor-standing unit combines heating with domestic hot water heating. The compact unit has a small footprint, but it offers big benefits. It features a high capacity 180L or 260L tank with 50% less heat loss compared to a standard tank. Intelligent controls offer a schedule function (heating the tank at a specific time of day) and a reheat function (automatically reheating when the temperature drops below a specified minimum) A well-insulated home will have varying heat load depending on the ambient conditions. A heating system is usually sized for the worst case scenario but an inverter based heat pump can vary its heat output to match the heat load of your home. Energywise solution will react and ensure you’re only consuming the exact amount of energy required to heat your home. The Daikin Altherma system is available in two different configurations, a monobloc system and a split system.
Energywise’s most popular air to water heating system is a split integrated system. The split integrated system has a small indoor footprint, it combines the hot water cylinder and the hydrobox in one sleek floor standing unit. Stacking the hot water cylinder and the indoor unit eliminates piping and reduces heat loss between the two units. This new floor standing configuration results in a compact footprint and drastically reduced installation times due in part to plug-and-play couplings. A programmable commissioning function for underfloor heating will gradually increase the system’s water temperature in time blocks of up to 72 hours to allow for proper screed drying.
The Daikin Altherma outdoor unit includes a heat pump that extracts heat from the outside air resulting in 2/3 of all usable heat coming from a sustainable and free source. Split systems are used when there are internal space constraints or when the distance between the outdoor unit and the cylinder/property is large. Pipes carrying refrigerant gas are laid between the outdoor unit and an internal wall mounted unit called a "hydrobox". A hot water cylinder is also required. The split system comes in sizes of 4-8KW and 11-16KW. The indoor unit can be wall mounted or floor standing which includes water cylinder.
A Daikin air to water heat pump can provide more than efficient heating for your home. It can also provide a total solution for domestic heating and hot water. The whole heat pump system can be connected to solar collectors, for even greater efficiencies. The solar energy helps to deliver 60% of your hot water energy needs throughout the year.
When there are internal space constraints, the Daikin monobloc air to water heat pump offers a perfect solution as it combines the compressor and the hydraulic components in a single outdoor unit. It contains all of the components to generate heating and hot water and output this to your property. The monobloc unit sits outdoors and comes in sizes of 6-8KW and 11-16KW. With a monobloc system, hot water pipes run between the outdoor unit and the hot water cylinder in the property.
In older or harder to heat properties, you need a system that reliably delivers higher water flow temperatures of up to 80ºC, without necessarily replacing the whole radiator system. The Daikin Altherma high temperature system can perfectly replace a traditional boiler and connect to the existing piping. The Daikin Altherma high temperature system is therefore the ideal heating and hot water solution for retrofit or refurbishment projects. The Daikin High Temperature heat pump range is unique in that it outputs hot water at a much higher temperature than standard heat pumps. It uses a two-stage heat pump system to raise the output water temperature to around 80°C. This high temperature system can be used in conjunction with existing steel radiators designed at a flow temperature of 70°C to 80°C so there is NO need to replace the radiators as well! The space saving design offers a modular configuration to ensure easy installation in even the smallest of spaces. Optional solar connection is available. It comprises of an outdoor unit, an indoor hydrobox and a hot water cylinder.
The Daikin Altherma heating system has the option of using solar energy for hot water production. Our customer like this product because it offers them flexibility for the future. With the HPSU compact, the retrofitting of a solar thermal system is incredibly simple. You don’t need to worry about finding extra space later on, as the heat pump is already prepared for everything. If the solar energy is not required immediately, the purpose-built hot water tank can store large quantities of heated water for up to a day for later use as domestic hot water or for heating.
An air to water heat pump works more efficiently than a traditional fossil-fuel boiler, generating 3kW of usable heat for every 1kW of electricity used. Talk about a good investment!
The Daikin Altherma air to water heat pump produces no direct CO2 emissions, so you personally contribute to a better environment. The pump does use electricity, but even without renewable electricity the CO2 emissions are still much lower than boilers that use fossil fuels.
An air to water heat pump takes heat from the air. No digging or excavation works are required. Both the outdoor and indoor units are compact. The external unit can be located easily outside any building, including flats. Without flames or fumes, there is no need for a chimney or constant ventilation in the room where the Daikin Altherma unit is installed.
An air to water heat pump uses a sustainable energy source. It extracts heat from the outside air which is free. The system consists of a closed circuit containing a refrigerant. A thermodynamic cycle is created through evaporation, condensation, compression and expansion. A heat pump “pumps” heat from a low to a higher temperature level. The heat raised is transferred to the water distribution system (under floor heating, low temperature radiators and/or fan coil units for low temperature heating systems and high temperature radiators for high temperature heating systems) in the home via a heat exchanger. A Daikin Altherma air to water heat pump delivers about 3kWh of usable heat for every kWh of electricity it uses. So this means that approximately 2/3 of your required home heating is free!
An air to water heat pump works without oil, gas or other hazardous substances, thus reducing the risk associated with these. Moreover, you don’t need a gas connection or a fuel tank. No risk of intoxication, smell or pollution from leaking tanks.
A Daikin Altherma air to water heat pump provides hot water and heating and is suitable for most domestic or (light) commercial projects – new build or retrofit.
Daikin offers 2 different air to water heat pump types:
Low temperature – new build applications
High temperature – retrofit applications
COP (Coefficient of Performance) or gain factor, this number indicates the amount of usable heat the heat pump delivers for every kWh electricity the heat pump uses. This number is dependent on the interior and exterior temperature and is therefore only a snapshot indicator.
SPF (Seasonal Performance Factor) or performance factor of the heat pump system. The SPF takes into consideration both the energy consumption of the heat pump system as well as the consumption by peripheral equipment, such as pumps, over the entire heating season.
I had been researching the new developments in renewable energy for a couple of years in preparation for my build. I met the Energywise Ireland team at their showroom in Blackpool in Cork City and found the team to be very knowledgeable. From the initial enquiry stage right through to the after care service has been of the highest quality and the ability to pop into the showroom at any stage is very reassuring. The team provided me with design drawings in advance of all works which gave me great assurance that I knew exactly what was being done in advance. The house is always very comfortable and we can’t believe how fresh the air is within our home. Our running costs have been very low to date and we are looking forward to a lifetime of comfort in our new energy efficient home.
