Understanding Heat Exchangers in Pumps for Heater Systems: A Guide to Sidite’s Core Technology


As the global market shifts toward cleaner and more efficient heating solutions, pumps for heater systems play an increasingly important role in residential and commercial water heating. At the core of every efficient system lies the heat exchanger—the component responsible for transferring heat effectively and reliably.

At Sidite, we specialize in innovative thermal technology and integrate two main types of heat exchangers into our pump systems:

Water-side heat exchangers (also known as condensers)

Air-side heat exchangers (also known as evaporators)

These are carefully selected and configured to ensure long-lasting performance and energy efficiency.


What’s the Role of Water-Side and Air-Side Heat Exchangers?


Type

Function

Location in System

Water-side Heat Exchanger (Condenser)

Transfers heat from the compressor into the water

Inside the pump for heater unit

Air-side Heat Exchanger (Evaporator)

Absorbs heat from ambient air to feed the system

Exposure to outside air


Water-Side Heat Exchangers Used by Sidite

✅ High-Efficiency Tank (Integrated Condenser)

Key Features:

Heat exchange coil is integrated inside or wrapped around the tank

Compact structure with built-in water-side condenser

Easy installation with no additional circulation system

Long-term energy-saving performance

Ideal for: Domestic water heating, compact pumps for heater units

✅ Plate Heat Exchanger

Keyword Highlight: Plate Heat Exchanger

Key Features:

Exceptional thermal transfer rate
