Heat Recovery Condensing Units...

The Forbes and Hunt Boilers Heat Recovery Condensing Unit (HRCU) is designed to fit to our TN-AR Hot Water Heater range, or can effectively be retrofitted to most other brands of industrial hot water heaters.

Depending on the return water temperature from the circulating system, our HRCU can gain up to 10% heat recovery over and above the current typical 83% combustion efficiency of the TN-AR, or other similar products.

After fitment of our HRCU you can expect to consume less input energy, while reducing flue related greenhouse gasses. This not only saves you money, but also significantly reduces any environmental impact.

Energy recovery is largely achieved by utilizing the latent heat released by condensing the water vapour in the flue gases when cooled below its dew point.

The key features of the Forbes and Hunt Boilers HRCU product range include:

Significantly lower fuel costs and lower greenhouse gas emissions through increased efficiency

Minimal additional pressure drop for both the water and flue gas circuits

Standard materials of construction include stainless steel heat exchanges, water collectors and flue collectors

Standard maximum working pressure is 1,500 kPa.

Easy access to inspection points allowing effective heat exchanger cleaning if required
