Dairy farm energy savings

HRC700 Heat Recovery Heating system

“Recycle the heat from your dairy farms waste wash water and reduce your water heating bill by up to 86%”

It’s expensive to run a dairy farm

There are a lot of fixed costs you can’t reduce.

You can control your energy spend through both low cost changes and cost effective capital investment.

The HRC700 is a New Zealand designed and patented system engineered to extract heat from your hot waste wash water before it goes down the drain, drastically reducing your power bill each month.

The system has been designed to work automatically to ensure no staff intervention is required and maximum energy savings are achieved.

By recycling heat from your plant and vat wash and using it in the next wash process, farms can save up to 85% on water heating costs, adding much needed profit to your farms bottom line. 


Reduces heating times - Heats 600L of water from cold to 80°c in one hour

No loss of performance during the season – Is not dependent on milk production

Can increase milking seasons by keeping costs down at the end of the season

Heats all the water you need when you need it

No need to change milking procedures, works automatically

Recovers wasted heat from plant & vat dirty wash water

Saves up to $1000 a month on power when using 1200L of hot water per day

Saves up to 86% on water heating costs

Can be moved from farm to farm (perfect for sharemilkers)

Are You A Sharemilker?

The HRC700 has been designed to be disconnected from and moved to another farm if required.

Most frequent questions and answers

Freshwater rises in temperature from around 14°c (average NZ ground water temperature) to 40°c.

Yes, the system is simple to disconnect and move.


The high-temperature heat pump ensures the water increases from 40°c up to 80°c efficiently ready for milk plant and vat washes.

No, The HRC700 works automatically. Depending on the placement you may require a transfer pump from the bottom of your vat to move wash water to the HRC700.

No, the system takes care of temperatures and timings automatically

Zane Wilson - Young

Inventor - Refrigeration Engineer - Energy Efficiency Expert

Three years ago when speaking with a dairy farmer at the Balclutha A&P show he asked me to explore where he was wasting energy on his dairy farm. It quickly became clear he was tipping $1000’s a year of energy directly down the drain. The engineer in me wanted to find a solution, a product to take the heat from the dairy farms waste wash water and transfer that energy into the freshwater filling the hot water cylinders.

I searched the globe for a product to do just that.

With no success, there currently wasn’t anything on the market to transfer or remove the heat, nor was there a product I could adapt to complete the task.

After years of working though the limitations of normal heat exchangers and the dairy shed processes, I have the final product. A system to take the heat from the dirty wash water and transfer it for sure in the next wash. Being able to preheat the water from 14°c up to 40°c, the natural progression was to use a high temperate energy efficient hot water heat pump to heat from 40°c to 80°c ready for use.

The HRC700 was born to provide farm owners and sharemilkers with a system to drastically reduce their power bill.

My passion is energy efficiency and helping clients reduce their power bills and I hope the HRC700 can help you too.
