RENEWABLE SOLUTIONS - AIR SOURCE - HEATING AND HOT WATER - OUTDOOR Air-Eau range

Performance characteristics Air-Eau uses an inverter-driven compressor. This effectively modulates the heat pump output to match heating demand, enabling the heat pump output to stay constant - even at very cold outdoor temperatures.

When air temperatures are warmer and heating demand falls, the heat pump output is reduced, maximising Air-Eau's efficiency (CoP).

Best-in-class efficiency Dimplex Air-Eau boasts impressive levels of efficiency, achieving CoPs of up to 4.7 in typical operating conditions, which can mean a significant reduction in running costs and CO2 emissions. In fact, across the range of models, output water temperatures and ambient conditions, Dimplex Air-Eau heat pumps exhibit best-in-class performance for efficient heating and hot water.

Inverter driven At the heart of Air-Eau is a variable-speed, inverter-driven compressor. This modulates the heat pump output to ensure it closely matches the heating requirements of the building as ambient temperatures change.

For example, a 12kW Air-Eau heat pump is able to provide the full heating demand at -5 oC. As the outside air temperature increases, the building's heat demand falls, so reducing the required output from the heat pump. The compressor power is reduced and the efficiency (CoP) increases.

Additionally, all Air-Eau inverter-driven heat pumps have low starting currents. Compressor power is gradually increased ensuring that starting loads are not a burden on the electrical netwrok infrastructure.

Variable flow temperature Weather-compensated water flow temperatures from the Air-Eau heat pump help to further maximise the system's efficiency. Weather compensation adjusts the heating water temperature from the heat pump based on the ambient outside temperature. So, as heat demand falls, lower flow temperatures can be used to achieve the same levels of comfort - while maximising heat pump efficiency. This can lead to up a 30% energy consumption reduction over the course of a year, compared to running at fixed flow temperatures.

Easy installation Dimplex Air-Eau's "monobloc" configuration provides the ultimate plumb-and-go solution, since it combines all the main system and hydraulic components in a single outdoor unit. This means that only the hot water cylinder and control valves are required to complete the system. Water pipes, rather than refrigerant lines, connect the heat pump to the building, allowing for speedy installation - and no need for refrigerant handling expertise.

Low noise levels Sound emissions from air source heat pumps are a sensitive subject and keeping these to a minimum is an important consideration for any installation. Dimplex Air-Eau models have extremely low sound levels at distance, typically as low as 50dB(A) at 1 meter. What is more, Air-Eau heat pumps feature an innovative "Night Mode"; this allows you to program the heat pump output to be lowered during the night, reducing the sound emissions even further.

Domestic hot water Dimplex Air-Eau heat pumps are an ideal choice for providing domestic hot water as part of the whole house solution. The intergrated heat pump controller provides full programming flexibility over hot water production. When paired with a Dimplex EC-Eau heat pump cylinder, Dimplex Air-Eau offer an efficient and environmentally-friendly way to meet your home's domestic hot water needs. The heat pump and cylinders are optimally matched using a large surface area heat exchanger; this maximises the transfer of heat generated by the heat pump to stored water. And because the hot water system is completely pressurised, you can enjoy fast filling baths, invigorating showers and plentiful, powerful hot water to multiple points around the home, simultaneously.

Bathrooms Any electrical appliances installed in a bathroom should be fitted by a competent electrician in accordance with the current I.E.E. Regulations. Portable heaters are NOT suitable for use in a bathroom. Unless otherwise specified, heaters that can be permanently fixed have to be so mounted that any controls cannot be reached by a person using a bath or shower. This restriction does not apply to Dimplex heated towel rails, which do not have controls.

Safety Dimplex products are designed to comply with EN60335 the British Standard covering the safety requirements of electric heating appliances, and momentary contact with any part of the heater should not cause injury. However, in order to be effective, heaters or towel rails of any type do get hot especially (if applicable) around the air outlet grille. Therefore if aged or infirm persons, or young children, are likely to be left unsupervised in the vicinity of a heater we advise that precautions should be taken. We recommend that a guard is fitted around the heater, as is normal with many types of heating appliances in similar circumstances, to ensure contact with the heater is avoided and objects cannot be inserted into the product. Heating appliances should never be covered or positioned where objects may fall onto them.
