With rising energy costs it makes sense to consider the installation of a heat-pump air to water under floor heating. This technology has been known for many years, but installations costs have been prohibitive. The major Japanese manufacturers in recent years have developed competitively priced highly efficient air to water heat exchangers. With high c.o.p.s. For every kilowatt of energy used upto 4kws or more can be absorbed by this system. Beeline Refrigeration supply and install Daikin Altherma Domestic heating systems as we feel they are of first class quality and extremely reliable.
The Daikin Altherma total heating and cooling system is based on heat pump technology and represents a flexible and cost effective
alternative to a fossil fuel boiler, with a cooling and sanitary warm water option.The inherent energy efficiency characteristics of
Altherma makes it an ideal solution to reduce energy consumption and CO2 emissions.
Altherma’s remarkable energy efficiency stems from its unique combination of the highly efficient Daikin inverter driven
compressor and variable set point temperature capability, which enables the system to match its output precisely to the actual
heating demand of the building. Furthermore, comfort is maximized and energy consumption minimized by its ability to regulate heat
emitter temperature to the optimum level. This is a typical Altherma under floor heating system.
The outdoor unit extracts free low temperature heat from the surrounding air and increases its temperature. Upgraded heat is then transmitted via the refrigerant circuit to the indoor hydro-box.
The indoor hydro-box transfers the heat in the refrigerant to the water circulated in the central heating radiators, under floor heating system and sanitary hot water tank. In the combined heating & cooling version of the indoor hydro-box cooling is achieved by reducing the water temperature to 4°C and circulating it through fan coil units. The system can also provide moderate cooling via the under floor heating system or radiators by limiting the lowest water temperature. The preparation of sanitary hot water is performed by switching the system from cooling or heating to sanitary mode.
A purpose built stainless steel water tank, constructed to maintain the highest levels of energy efficiency, is available to meet sanitary hot water needs. The combination of an electric booster heater in the upper part of the tank and a heat pump heat exchanger in the lower part ensures the lowest possible energy consumption with rapid water heating. In addition, a built in function raises the water temperature to 70°C or higher at least once a week to remove any possibility of legionella growth.
Our fan coil range can be connected to the Altherma system for cooling.
System controls and the user interface are contained within the hydro-box and feature a weekly timer that enables the indoor temperature to be controlled according to user requirements. The timer is programmable on an hourly or daily basis so that temperatures can be reduced at night or during holidays and increased prior to rising in the morning or returning home. User comfort according to personal preference is thus maintained at all times. Where control over individual room temperatures and comfort levels is needed a conventional room controller should be added.
The under floor heating system which would include the header manifolds, control valves and room thermostats would be installed in addition to the Altherma system. This system is compatible with modern conventional under floor heating systems and can replace existing fossil fuel powered boilers.
