Domestic & Commercial Engineering solutions
Due to the current energy concerns and the associated rise in fuel costs, viable renewable alternatives are becoming increasingly important. BCD Energy offer a wide range of products and solutions to ensure that your heating system is specified for your individual requirements.
Air-to-water heat pumps, due to their ease and low cost of installation, are both economically viable and environmentally friendly as a renewable alternative to traditional heat generators. The high efficiency of the Aermec ANZ range, even in harsh outdoor conditions, ensures low power consumption and running costs throughout the year. They can be installed in any building at any stage, existing or new-build, along with any back-up system, oil, gas or electrical.
The Aermec ANZ Series air-to-water unit contains the new high efficiency Copeland ZH scroll compressor, designed specifically for heat pumps. The compressor features more extended operating ranges, making it possible to run the heat pump in harsh conditions. These heat pumps have a COP up to 20% greater than traditional air-to-water heat pumps.

Low power consumption and running costs, even in harsh conditions
The large surface area of the heat exchangers means that, since the required fan speeds are lower than with other air source heat pumps, this unit is very low noise. Additionally, the compressor is mounted on shock absorbers and the heat pump is fitted on anti-vibration mounts, reducing structure borne noise.
Aermec ANZ Series heat pumps are available with the following features:
Aermec air-to-water heat pumps consist of one compact unit, with no requirement for any special installation space. The heat pump, control panel, buffer tank and electrical back-up are contained in one unit, comparable to the size of a washing machine. Since there is no collector, there is no impact on garden space and no additional installation cost associated with boreholes or horizontal loops.
Aermec Air-to Water heat pumps, unlike traditional air-to-water units, do not stop heating during their defrost cycle.
The control system includes weather compensation, allowing the water set-point to be adjusted based on the out door air temperature and the building heat requirement. This provides optimal comfort throughout the year and maximises the efficiency of your heating system.
A low temperature heat distribution system like under-floor heating is ideal for use with a heat pump. The large surface area of the under-floor system in comparison with conventional radiator heating systems means that the required heat output can be achieved with much lower floor surface temperatures. For new build homes, this is the ideal solution.
The Waterkotte hot water system, designed specifically for use with heat pumps, comes available for installation with all our DS Series geothermal systems.
The Waterkotte Hygienic Hot Water Module heats water directly as it is drawn from the tap. Mains water is diverted past a thermal store, which is heated to 55ºC by the heat pump. The water is heated instantly by a high efficiency plate heat exchanger
Waterkotte hot water heating offers an abundant supply of the highest quality water, i.e. it offers hot water of the same, or better, quality as running tap water.
Energy is absorbed by the earth from the sun throughout the year and stored in large quantities in the subsoil. The atmosphere absorbs this solar energy from the ground. The energy is entirely renewable but, on cold days, when heating is required, it is relatively low-grade compared with the energy in a building. As a result, it cannot be used directly for heating. Our task is to upgrade this energy.
To achieve maximum efficiency, the temperature of the air must be as high as possible and the flow temperature on the heating side must be as low as possible. Unlike a ground source heat pump, the efficiency of an air source heat pump decreases with the outside temperature, while the heat load of the building simultaneously increases. With the correct design of the heating system from heat source to heat distribution, Airmec air-to-water heat pumps can achieve a co-efficient of performance (COP) of up to 3.5 (defined for an air temperature of 7ºC and a heating side flow temperature of 35ºC), i.e. for every 1kW of electrical power used in the compression stage, there is 3.5kW of heat output, 2.5kW of which comes free from the air.
