Description

ecosmart™ LVP ES50LVP Modulating Hydronic Air Handler

The ecosmart™ LVP ES50LVP is a fully modulating hydronic air handler engineered to get the most out of modern high-efficiency boilers and water heaters. Designed for residential and light commercial applications, it lets you combine space heating and domestic hot water in one smart, compact system while maintaining exceptional comfort and performance.

With a nominal capacity of 1 to 2 tons and a heating output range of 29,610 to 66,110 BTU/hr, the ES50LVP is a powerful, flexible solution for combo systems, retrofits and new construction projects.

Smart Modulating Hydronic Design

What sets the ecosmart™ LVP apart is its ability to modulate both fan speed and pump speed simultaneously. The built-in smart controller monitors system parameters and adjusts air and water flow in real time, allowing condensing boilers and high-efficiency water heaters to operate in their most efficient condensing range while still delivering consistent, comfortable heat.

This intelligent control helps:

• Maximize efficiency from CAN/CSA-P.9-11 rated systems
• Reduce temperature swings and cycling
• Improve comfort and system longevity

Built-In Variable-Speed Pump Controller

The ES50LVP includes a built-in variable speed pump controller capable of varying the speed of a standard single-speed AC pump. This means you get modulating hydronic performance without needing an expensive ECM circulator.

By varying both the fan and the pump:

• Water flow and air flow stay matched to the load
• Return water temperatures are kept low for optimal condensing operation
• System efficiency and comfort are significantly improved over fixed-speed systems

Flexible Operating Modes

The ecosmart™ LVP series is built to adapt to a wide range of applications. It can be configured in the field for:

• Full modulation – for maximum comfort and efficiency
• Multi-stage operation – to match with staged controls
• Single-stage operation – for simpler systems or retrofit situations

Installers can independently set heating and cooling fan speeds from 300 to 2000 CFM in 100 CFM increments, giving very fine control over airflow and noise level.

Comfort-Focused ECM Fan Motor

A high-efficiency ECM fan motor delivers nearly constant CFM across a range of static pressures. This means:

• More consistent airflow to each room
• Better duct performance, even in higher resistance systems
• Lower energy consumption at part-load conditions

Soft-ramping fan technology brings the blower up to speed gently and quietly, enhancing comfort and reducing noise in all operating modes.

Dehumidification and Cooling Integration

The ES50LVP is more than just a hydronic furnace. With its built-in dehumidification feature and adjustable fan speeds, it works extremely well in applications where cooling coils are present, providing:

• Improved humidity control during cooling
• Adjustable airflow to fine-tune coil performance
• Better overall indoor comfort throughout the year

Domestic Hot Water & Combo System Friendly

The ecosmart™ LVP series is designed from the ground up to integrate with:

• High-efficiency boilers
• Tank-type water heaters
• Tankless water heaters
• Other hot water sources

A domestic water priority option allows you to give hot water production priority over space heating when needed, which is crucial in combo systems. The sophisticated but installer-friendly microcontrollers simplify these setups and help ensure the system is delivering both hot water and heating exactly as intended.

Installer-Friendly Controls & Setup

The ecosmart™ controller is built to make commissioning straightforward. Installers can:

• Set outdoor design temperature and modulation behavior
• Independently select heating and cooling speeds
• Choose operating mode (full modulation / multi-stage / single-stage)
• Monitor key parameters and adjust as needed

All of this is done through proprietary microcontrollers designed specifically for hydronic/air handler integration, helping to reduce setup time and eliminate guesswork.

Compact, Quiet Multi-Position Cabinet

With dimensions of 29″ H × 14″ W × 21″ D, the ES50LVP fits easily into tight mechanical rooms, closets and small spaces. The cabinet is:

• Multi-position – suitable for a variety of installation orientations (check manufacturer instructions for approved positions)
• Front or rear water connections – giving more piping flexibility
• Lined with acoustic insulation – to reduce noise and improve comfort

A standard 16″ × 20″ filter size makes replacements easy and helps maintain good indoor air quality.

Ideal Applications

The ecosmart™ LVP ES50LVP is an excellent choice for:

• Hydronic combo systems using condensing boilers or high-efficiency water heaters
• Homes that want boiler-quality comfort with forced-air distribution
• Retrofits where existing ductwork is present but a furnace change-out is planned
• Light commercial spaces that benefit from modulating hydronic systems

If you’re designing a high-efficiency hydronic/forced air system and need a smart, compact air handler that can fully leverage condensing technology, the ecosmart™ LVP ES50LVP Modulating Air Handler is built for that exact job.
