What is the Envirosun HP Plus Heat Pump All About?
We live in an era where people care more about energy efficiency and environmental consciousness of their hot water heat pumps. That’s why the Envirosun HP Plus Hot Water Heat Pump is getting more attention. This innovative air source heat pump represents the next generation of energy-efficient water heating technology, specifically designed for New Zealand homes and families.
At the heart of the Envirosun HP Plus is its ingenious heat pump technology, which operates on a principle similar to a reverse refrigerator. While a refrigerator extracts heat from an enclosed space and releases it into the surrounding air, the HP Plus does the opposite – it captures heat from the ambient air and transfers it to water stored in an enclosed tank. This remarkable system maintains its efficiency even in temperatures as low as -7°C, demonstrating its versatility across various New Zealand climate conditions.
What sets the HP Plus apart is its impressive energy conversion ratio. The system can transform 1kW of electrical input into more than 4kW of heat output, achieving a Coefficient of Performance (COP) of up to 4.16. This translates to significant energy savings, making it up to 73% cheaper to run compared to conventional electric hot water systems.
Key Features and Benefits of the Envirosun HP Plus Heat Pump
Environmental responsibility is at the forefront of the HP Plus design. The system uses R290, a natural refrigerant, marking a significant departure from harmful refrigerants commonly used in other systems. This eco-friendly choice reflects growing consumer demand for sustainable home solutions and demonstrates Envirosun’s commitment to environmental stewardship.
The unit features an intuitive TFT LCD control screen that remains visible in any lighting condition. This user-friendly interface makes operation straightforward and accessible for all family members. The system includes customisable operating modes to suit different lifestyle needs:
All Electric mode for traditional operation
Fast Recovery mode for quick hot water replenishment
Eco mode for maximum energy efficiency
Mute mode for silent overnight heating
You don’t need to worry about capacity and durability of the Envirosun HP Plus Hot Water Heat Pump. Here’s why:
It is in both 200L and 330L models, the HP Plus offers the market’s largest capacity range, accommodating families of all sizes.
The system’s durability is enhanced by triple full-length anodes. It ensures maximum longevity and reliability.
This robust construction is backed by a comprehensive 7-year tank warranty, providing peace of mind for homeowners.
One of the standout features of the HP Plus is its whisper-quiet operation. Let’s explore more on it as well.
Quiet noise levels of just 42dBA during operation (measured at 2 meters)
You will enjoy peaceful coexistence with both household members and neighbours.
This makes it particularly suitable for dense residential areas where noise pollution is a concern.
The HP Plus truly shines when paired with solar PV systems, making it an ideal choice for homes with existing solar installations or those planning to add solar power in the future.
The system can store up to 21kW of heat energy in its tank, particularly impressive in the 330L model.
This stored energy remains available for use even after sunset, maximizing the benefits of solar power generation.
The advanced control system includes an automatic timer that optimises solar power utilisation, along with a secondary timer for early morning boosting.
It ensures a constant supply of hot water while maximising energy efficiency and cost savings.
The HP Plus boasts impressive technical specifications that support its performance claims:
Operating ambient temperature range: -7°C to 45°C
Default temperature setting: 60°C
Maximum heat pump temperature: 65°C
Water heating capacity: 3200W-3300W
IPX4 waterproof rating
Multiple safety features including frost protection, legionella protection, and overheat protection
Installation and Space Requirements
The system requires minimal installation space, though proper clearance is essential for optimal performance. The design specifications call for at least 300mm of clearance around air outlets and 10mm for the condensate drain. The modern styling complements contemporary architectural trends, making it an aesthetically pleasing addition to any home.
