Enviroair Air Source Heat Pumps

Domestic Hot Water and Underfloor Heating

Enviroair Heat Pumps can provide domestic hot water (up to 65°C) and underfloor heating, improving room comfort.

Compact Footprint and Sleek Design

Designed for installation in any type of property, especially homes with limited space. As this is a compact system with a single unit installed outdoors, the available space indoors remains unchanged.

Easy Installation & Maintenance

All functions are achieved with a single outdoor unit, bringing significant cost savings. Furthermore, installation is quicker and easier as there is no need for refrigerant piping and the product is pre-charged at the factory. Two-door design for easy access to internal components for easy maintenance.

Eco Friendly Refrigerant R32

• Lower GWP 675 (GWP: Global Warming Potential).
• Zero impact on the ozone layer and less carbon emission.
• Higher heat transfer coefficient.
• Better performance in poor conditions.
• Less pressure loss and no temperature glide.
• Less charged volume and less cost.

Inverter System Design

The DC compressor, fan motor and pump allow precise control of the motor speed, ensuring that only the power necessary to perfectly match the real load is used. Thereby saving energy.

Powerful Heating with High Efficiency

A+++ ErP energy rating. Efficient heating capacity even when at -7°C air temperature. Maintains continuous hot water supply up to 65°C, even with outdoor temperatures as low as -20°C.

• Operation range down to -25°C.
• Maximum LWT reach 65°C for 4~16kW models.

ErP Directive*

ns. Seasonal space heating energy efficiency.
ns average up to A+++ at 35°C.
ns average up to A++ at 55°C.
*Indicates the highest possible grade for M thermal product lineup. For specific grade of different models, please refer to the specification.

Silent Mode

The 4kW model produces 35dB(A) sound pressure level at 3 meters thanks to multiple optimisation design.
Test conditions:

1. Outdoor air temperature 7°C DB, 6°C WB; Water inlet 30°C, Water
   outlet 35°C.
2. Outdoor air temperature 35°C DB; Water inlet 23°C, Water outlet 18°C.

Smart Controller & App

• Multiple languages for customer needs.
• Modbus protocol and network flexibility.
• Built-in wifi module supports remote control.
• Holiday away and holiday home makes life convenient.

iLetComfort APP

Note: APP interface changes from time to time as it is updated and may vary slightly from those in this document.

Flexibility

A cascade system design is perfect when a higher capacity is required as the building demand evolves. A maximum of 6 units can be controlled in a group with one controller. The balance tank temperature control makes the water temperature more accurate.

Notes:

1. Balance tank (supplied).
2. Balance tank temperature sensor (can be supplied).
3. 3-way valve (supplied).
4. Fan coil unit (can be supplied).
5. Floor heating loop (supplied).
6. AHS: Additional heating source (supplied).
7. Water tank (supplied).
8. Heat exchanger coil(supplied).
9. Single way valve (supplied).

USB Function

• Programs can be conveniently updated with a USB.
• Installers can manage parameter transmissions from one controller to another via USB, saving time.

Climate Curve

The water temperature automatically changes as the ambient temperature changes. This is convenient and leads to energy savings for the end user. 32 fixed climate curves and 1 customised curve is available, covering different requirements.

Smart Grid

In order to save energy, the Enviroair heat pump adjusts the operation mode according to the different grid signals. When the electric price is low or even free, the heat pump prioritises DHW. When the electricity price is high, DHW related functions are limited. When the electric price is normal, the heat pump operates according to the user’s requirements
