šæ DHW Tanks for Heat Pumps – High-Efficiency Domestic Hot Water
š”ļø Engineered for Low-Temperature, High-Performance Heating
Standard water cylinders often struggle when paired with modern heat pumps. The DHW Tanks for Heat Pumps category at Termix.ro provides the specialized storage solutions needed to bridge this gap. Because heat pumps operate at lower flow temperatures ($35^\circ\text{C} - 55^\circ\text{C}$) compared to traditional gas boilers, they require a significantly larger heat exchange surface to transfer energy effectively into your domestic water. š
Our heat pump cylinders feature "oversized" internal coils, ensuring your system maintains a high COP (Coefficient of Performance) while providing a steady supply of hot water for showers and baths.
āØ Key Features of Our Heat Pump Cylinders:
-
š Extra-Large Heat Exchangers: Features internal coils with up to $2\times$ or $3\times$ the surface area of a standard cylinder. This allows for rapid heat transfer even when the heat pump is running at its most efficient low temperatures.
-
š”ļø Premium Enamel or Stainless Steel: Choose between high-grade glass-lined (enamelled) steel with sacrificial anodes or maintenance-free stainless steel tanks for maximum hygiene and lifespan.
-
š§„ Superior Energy Insulation: Wrapped in high-density, CFC-free polyurethane foam (C or B class) to ensure minimal standby heat loss, keeping your water hot for hours with zero energy input.
-
ā” Integrated Backup Heater Port: Equipped with a dedicated 1 1/2" port for an electric immersion heater ($kW$), essential for the weekly anti-Legionella thermal disinfection cycle.
-
šļø Strategic Design: Slimline and vertical models available to fit into compact mechanical rooms alongside your indoor heat pump unit.
š Why a Specialized Tank is Essential for Your Heat Pump:
-
Maximized Efficiency: A large coil prevents the heat pump from "ramping up" to inefficiently high temperatures, saving you money on every $kWh$. š
-
Fast Recovery Times: Even at lower input temperatures, these tanks can reheat 300L of water in a fraction of the time of a standard cylinder. ā²ļø
-
Bacteria Protection: Designed to handle the higher flow rates required during a "Booster" cycle for domestic hygiene. š¦
-
System Longevity: Reduces the workload on the heat pump compressor by allowing it to operate in its most stable, efficient thermal range. ā³
š” Expert Advice from the Termix Team:
-
The "Surface Rule": For a standard air-source heat pump, you generally need a coil surface area of at least $0.25\text{ m}^2$ to $0.3\text{ m}^2$ for every $1\text{ kW}$ of heat pump power. š
-
Anti-Legionella Cycle: Since heat pumps usually store water at $45^\circ\text{C} - 50^\circ\text{C}$, ensure your controller is set to use the electric immersion heater once a week to raise the tank temperature above $60^\circ\text{C}$. š”ļø
-
Sensor Placement: Use the dedicated sensor pocket (thermowell) located near the middle of the coil for the most accurate temperature reading, preventing the heat pump from over-firing. š±
