CDR DLX 25L (Horizontal) Specifications, Features & Compatibility Guide
The CDR DLX 25L (Horizontal) is a 25 LL Racold storage water heater designed for reliable daily hot water supply across Indian households.The 25 LL storage capacity comfortably supports a family of three to four for back-to-back morning showers.
Quick Answer
Yes, the CDR DLX 25L (Horizontal) is a smart investment if you require an energy-efficient, mid-capacity water heater for a family of 3-4. Its 4-star BEE rating ensures reduced running costs, while the 25L storage and dependable copper heating element provide a consistent hot water supply. The horizontal design further offers versatile installation options, making it a practical choice for modern Indian households.
Opt for the CDR DLX 25L (Horizontal) if you prioritize 4-star BEE energy efficiency and reliable hot water for a residential family of three to four. This model is best avoided if your usage demands exceed typical residential capacity or if your budget prioritizes minimal upfront capital expenditure over long-term energy savings.
✓ Who Should Buy
- • 4 Star performance suitable for residential spaces.
- •Verified efficiency of standard rating for reduced long-term operational costs.
- •Structural stability for consistent cleaning under rigorous use cases.
- •Hardware durability via premium components and advanced technology.
- •Built-in grid protection with Standard power cycle voltage management.
✕ Who Should Avoid
- •Spaces or usage requirements exceeding residential rated capacity.
- •Installations prioritizing minimum capital expenditure over high-efficiency performance.
- •Unstable grid conditions exceeding the functional threshold of Standard power cycle.
- •Environments incompatible with water geyser physical and thermal dissipation specs.
Product Overview
The CDR DLX 25L (Horizontal) is a 25 LL Racold storage water heater designed for reliable daily hot water supply across Indian households. The 25 LL storage capacity comfortably supports a family of three to four for back-to-back morning showers. A copper heating element ensures fast thermal conductivity and precise heating, though periodic descaling is recommended in hard water areas. Inside, a glass-lined tank creates a permanent non-reactive barrier, preventing rust and corrosion regardless of water mineral content. With a 4 Star BEE energy rating, the CDR DLX 25L (Horizontal) ensures meaningful electricity savings across every month of operation, directly reducing utility bills. High-density PU Foam insulation wraps the tank to minimize standing heat loss, keeping water hot for extended periods without re-heating cycles. Rated for 0.5-8 bar pressure compatibility, this unit handles the high-pressure pumping systems commonly found in modern Indian high-rise apartments. Racold backs this unit with a 24-month product warranty and a 60-month tank warranty, reflecting strong confidence in build quality and durability.

Engineering Analysis
PU Foam insulation in the CDR DLX 25L (Horizontal) is an engineering choice that minimizes standing heat loss, reducing reheat frequency and directly contributing to the 4 Star rating compliance. The 2 kWkW Copper heating element provides the thermal wattage required to heat the tank within acceptable timeframes while maintaining element longevity under repeated thermal cycling. Glass-lined tank technology involves applying a vitreous enamel coating to the inner steel surface at high temperatures, fusing the glass permanently. This creates a chemically inert barrier that no dissolved mineral can penetrate, solving the primary failure mode of budget geysers in Indian hard-water conditions. Safety architecture in the CDR DLX 25L (Horizontal) is built around 5 independent protection mechanisms: Dry-Heat Protection, Pressure Relief Valve, Thermal Cut-Out, Anti-Scalding, Over-Temperature Cut-Out. This layered approach ensures no single point of failure can lead to a hazardous outcome, which is critical for unattended residential operation. The Mechanical thermostat controls the heating cycle within a 25-75 °C°C range, maintaining consistent output temperatures through daily usage patterns. With a 0.5-8 bar pressure rating, the tank and valve assembly are stress-tested to handle the peak pump pressures in modern multi-storey residential buildings, where line pressure routinely exceeds the tolerance of standard geysers.
