Reduce Your Carbon Footprint with Air Energy

Air to Water Heat Pumps


Based on the "Reverse Carnot Cycle" principle, air to water heat pump is a type of air source heat pump (ASHP) systems, which utilizes energy from the air to generate heat and provide domestic or commercial hot water, house heating and/or cooling. Small heat pumps are usually designed for domestic settings.

SPRSUN is one of the leading air to water heat pump manufacturers in China, which provides several types of air to water heat pumps such as hot water heat pumps, DC inverter (monoblock & split types), EVI low temp, household, and swimming pool heat pumps.

Air to Water Heat Pump Sourcing Guide

Before choosing a manufacturer of air to water heat pump or selecting the type of air to hot water heat pump for certain applications, there is some information to note.

What is an Air to Water Heat Pump?

An Air to Water Heat Pump is a heating and cooling system that extracts heat from the outdoor air and transfers it to a water-based heat distribution system. There are two basic types: Monoblock Heat Pump and Split System Heat Pump.

How Does Air to Water Heat Pump Work?

Basically, an air to water heat pump works by extracting heat from outdoor air and transferring it to a water-based heating system. It comes with a refrigerant in the evaporator that absorbs heat, then compresses it into high temperature and high pressure gas, providing efficient heating for residential, commercial, or industrial spaces.

Air-to-Water Heat Pump Installation

The air to water heat pump is positioned outdoor in a central position with connection to the indoor unit, as well as the water distribution system, which includes the water tank, heat pump kit, floor heating plumbing and buffer tank. They are all linked to the various fan coils.

How to Select the Trustworthy Air-to-Water Heat Pump Supplier and Manufacturer

Selecting a manufacturer and supplier for your high or low temperature heat pump is crucial. Because it makes or breaks your business and word of mouth. The factors below should be carefully examined and consulted before choosing from the many air to water heat pump suppliers on the market.
Minimum Order Quantity (MOQ)
Confirm if the MOQ of the air to water heat pump supplier accommodates the quantity you want to order. At SPRSUN, we offer a MOQ of 3 units, allowing both small and bulk orders.
Turnaround Time and Packaging
Confirm how long it will take to deliver your order and how safe the packaging is. At SPRSUN, we are done with production within one month, and the heat pumps are packaged in strong wood containers to avoid damage during transportation.
International Quality Certificates
Firstly, confirm if the air-to-liquid heat pump's production standards conform with your target market's regulations. SPRSUN products are manufactured based on EN14511 standard with MCS, TUV, KEYMARK, BAFA, SAA, ERP, RoHS, and CE certificates. We also comply with specific regional standards to help you gain access to the market.
Is There A Provision for Accessories & Replacement Parts?
Check if the air to water heat pump supplier provides accessories and replacement parts for heat pumps in case of damage. SPRSUN provides a heat pump installation kit and accessories to reduce installation costs and time. You don’t need to buy new installation kits and replacement parts.
