How It Works

An air to water heat pump uses a fan and heat exchanger to harvest free energy from the air outside your home.  This energy is transferred to your hydronic distribution (in floor heating, radiators, etc.) using a compressor and refrigeration cycle.   You only pay for the electricity to run the fan and compressor. The rest of the energy is free and renewable from the environment. It’s so efficient, you’ll use up to 66% less energy.

Why an ATW Heat Pump?

If you have radiant infloor heating and you want low operating costs, an ATW heat pump makes so much sense.

• Hydronic distribution and heat pump delivery temperature are a perfect match.
• 2 in 1 – Floor cooling is an easy add on, and it costs way less than a separate air conditioning system.
• No fossil fuels or carbon monoxide worries, make everyone breathe easier.

Why Stage 3?

We’re experts at getting the most out of this technology and ensuring your system is reliable.  There are numerous manufacturers and configurations available. Stage 3 Renewables will work with you to get the best solution for your home.

• We specialize in radiant infloor heating too. We can provide a complete package that sets your home apart from the rest.
• We can custom design a hydronic heating system for whatever you want to build.
• Retrofit? No problem! Retrofitting hydronics is easier and more flexible than forced air (ducted) systems.
• Stage 3 Renewables means higher performance and better value.
