Water heat recycling from wastewater to warmth is a game-changer for reducing energy consumption and greenhouse gas emissions. This innovative technology has the potential to significantly decrease our reliance on fossil fuels and mitigate the effects of climate change.
By utilizing wastewater as a heat source, we can tap into a readily available resource that would otherwise be wasted. Wastewater can be heated to produce hot water, which can be used for various purposes such as space heating, water heating, and even generating electricity.
In fact, studies have shown that wastewater heat recycling can reduce energy consumption by up to 70% compared to traditional heating methods. This is a staggering statistic that highlights the potential of water heat recycling to make a significant impact on our energy usage.

What Is Water Heat Recycling?
Water heat recycling is a clever way to reuse heat that would otherwise be wasted. This process can provide significant energy savings, depending on various factors such as energy costs, location, and system configuration.
In fact, if your hot water is supplied by a 78% efficient natural gas hot water tank, a DWHR unit can recover enough heat to provide up to 15% of your overall hot water needs, which is equivalent to about 130 m3 of gas.
The type of hot water heater also plays a crucial role in determining the potential energy savings. For example, if you have a conventional electric hot water tank, a DWHR unit can recover enough heat to provide up to 20% of your overall hot water needs for the household, which is about 1100 kWh.
Wastewater Services and Benefits
Kemco's Heat Recovery Wastewater Services are designed to be wall or ceiling mounted, so they don't use valuable production floor space.
By using a heat reclaimer, you can provide more than one preheated temperature, which is perfect for hot and tempered water systems. This can be especially useful in commercial laundromats or kitchen operations where large amounts of hot water are used.
Stainless steel construction assures optimum corrosion resistance and longer operational life, meeting or exceeding TEMA standards for shell and tube heat exchangers.
You don't need to filter the wastewater before entering the unit, which eliminates additional electrical consumption required by filtration systems and provides hotter wastewater to the reclaimer.
Wastewater is a renewable heat source that can be reused, and it's estimated that factories use enormous amounts of hot water to clean processing equipment.
The major benefits of wastewater heat recovery include a reduction in primary energy used and cost savings for preheating the cold-water supply in a building or space-heating.
A heat exchanger is a device that facilitates the transfer of internal thermal energy between two fluids without mixing the fluids, making it a passive technology that doesn't require any external energy.
Recovered wastewater thermal energy can be used in a variety of applications, from heating swimming pools and showers to drying sludge or heating industrial process liquids.
Kemco's heat reclaimers come with a 20-year warranty and have a 4-Way Back Flushing System that guarantees against plugging and eliminates the need for manual cleaning of the exchanger.

Wastewater Recovery and Requirements
Wastewater is a renewable heat source that can be reused to benefit the environment and businesses. Typical equipment for wastewater heat recovery is heat exchangers and heat pumps.
Heat exchangers are devices that facilitate the transfer of internal thermal energy between two fluids without mixing the fluids. This is a passive technology that does not require any external energy.
A heat pump, on the other hand, is a technology that uses electricity and the reverse refrigeration cycle to transfer heat from one place to another. In some systems, the heat exchanger is used in conjunction with the heat pump.
Wastewater heat recovery systems can be designed to provide up to a 5°F "approach", which means they can preheat incoming fresh water to within 5°F to 10°F of the wastewater stream.
Kemco's Wastewater Services can recover potentially lost thermal energy by capturing the heat from the wastewater and using it to preheat the incoming fresh water.

Tanneries
Tanneries are a great example of where waste heat recovery can make a big impact. Dirty water discharges in tanneries are often mixed into a single low-temperature stream, typically between 30-40°C.
This dirty water contains a large amount of mechanical pollutants. RHeX waste water heat exchangers can make use of this low-enthalpy energy content.
By combining waste water heat exchangers with heat pumps, tanneries can produce clean pre-heated water for their process. This makes the tannery virtually steam-free.
The overall coefficient of performance of this type of waste heat recovery is extremely attractive, making the investment profitable.
