With the right choice of accumulator tank, you can connect different heat sources and use them as appropriate, future-proofing your heating system and giving you the flexibility to adapt to the most cost effective heat source.
The Aqualux 500 Teknik is a 500 litre accumulator tank comprising of a 160 litre internal copper lined domestic hot water (DHW) tank and 360 litre heating jacket. The Aqualux 500 Teknik also features a built in solar coil (surface area 2.5m2 ) which is ready equipped for solar thermal panels. An air source heat pump can also be attached. Two ports are available for electric immersion heater elements (accessory).
Volume / size
The Aqualux Teknik accumulator tank is available in 500 litre , 750 litre and 1000 litre sizes.

Expansion
The Aqualux range of accumulator tanks have been designed to be easily cascaded, allowing them to be expanded to accommodate larger buffer volume requirements.
Choose from Aqualux Teknik tanks (with solar coil and internal 160 litre DHW tank), Aqualux CU (with internal 120 litre DHW tank) or the basic Aqualux UB accumulator tank.
Flow restrictors & stratification plates
Varmebaronen Aqualux Teknik tanks have unique flow restrictors and stratification plates which enables them to handle several heat sources at the same time without them disturbing the stratification in the tank and thus cancelling each other out.
Cold water is denser than hot water therefore sinks allowing the hot water to rise to the top of the tank. The stratification plates enhance the stratification and provide defined layering between hot and cold water.
The Aqualux Teknik range of accumulator tanks has up to 25 times the stratification-retaining properties of a standard thermal storage tank. This allows a heat pump's coefficient of performance (COP) to be increased from 2.48 to 3.78, which means a 65% increase at a mean outdoor temperature of 2°C. Solar thermal panel output can increase by 60-70% during the winter half of the year.
Internal 160 L domestic hot water tank (DHW)
The Aqualux Teknik range of accumulator tanks feature an internal 160 litre copper-lined domestic hot water tank, providing plenty of hot water for most requirements.
Aqualux Teknik accumulators have 15-20% higher buffer capacity than a good coil tank and produces hot water - even when the tank is almost discharged. If you have a solar thermal panel, the tank can cope with several cloudy days. Your log or pellet boiler will required to fire less frequently.
Thermometers
The thermometer dials for the top, centre and bottom of the Aqualux accumulator tank are co-located at the top of the buffer tank you can always see the temperature of the water inside the tank at a glance and you do not need to bend down to read the temperature.
Insulation
Aqualux Teknik accumulator tanks are insulated with 90mm mineral wool insulation using a special tool which avoids squeezing or reducing the fluffiness of the insulating material, which produces a higher efficiency and saves you money.
Optional Shunt for extra efficiency
Optional shunt pack for increased efficiency.
Optional shunt pack for increased efficiency.
An optional bivalent shunt pack is available for the Aqualux Teknik which further increases efficiency by allowing water to be taken from the middle of the tank first, then the top, which helps to maintain stratification and ensures the domestic hot water tank remains hotter for longer.
The shunt should be supplemented with automatic shunt control. This mixes hot water from the middle of the buffer tank with the hottest water from the top of the tank, creating a perfect blended mix of hot water that is the right temperature for the properties heat requirement at that moment. This stops all of the hot water from being drained from the top of the tank which would cool the DHW tank and impact on the buffer tanks stratification. Varmebaronen recommend the LK 110 SmartComfort RTW (actuator) with wireless room temperature unit (thermostat) by LK Armatur. The room temperature unit has 6 pre-programmed settings that will suit most people. User can also save their own settings.
