Are Drain Water Heat Recovery Systems Worth It?

A large portion of the energy use in domestic water heating is lost to the drainage channels. Channel by applications such as showers, baths, dishwashers, and so on. It has been demonstrating that recovering waste heat from domestic wastewater flow is a sustainable method of increasing and building energy efficiency. Water heating accounts for up to 20% of total home energy consumption, ranking second only to space heating in terms of energy consumption. Drain Water Heat Recovery (DWHR) systems are an energy-saving technology that can reduce the energy consumption of your water heater by up to 25%.

How Drain water heat recovery does it work?

Heat is a capture from hot water going down the drain and used to preheat cold water entering your water heater by drain water heat recovery systems. As a result, the amount of energy required to heat water to the desired temperature is reduced. When you use hot water while it is also flowing down the drain, such as during a shower, you save energy. This is referred to as concurrent flow consumption.

Benefits of Using Drain Water Heat Recovery

  1. Energy Savings

A typical drain water heat recovery system can save up to 25% on your water heater’s energy consumption. You’ll save money on your energy bills if you use less energy.

  1. Extend the Life of Your Water Heater

Because the drain water heat recovery system pre-heats the cold water entering your water heater, the water heater does not have to work as hard to heat the water, extending the life of your water heater.

  1. Flexibility

It can be used with any type of water heating system. As technology advances, your drain water heat recovery system will help to reduce the energy consumption of any future water heating system you choose for your home.

  1. Simplicity and Reliability

A drain water heat recovery system is made of copper. And, has no moving parts. So it doesn’t need to be maintained regularly. The system has a product life expectancy of more than 30 years. You can simply forget about it. And once it’s installed and reap the benefits of lower energy consumption and lower utility bills.

How Does it Save?

Energy costs, location, system configuration, water heater type, and water usage influence cost savings. If the hot water is provided by a 78 percent efficient natural gas hot water tank. It may be possible to recover enough heat. Heat to meet up to 15% of the total hot water requirements (about 130 m3 of gas). If a traditional electric hot water tank provides the hot water. The unit may be able to recover enough heat to meet up to 20% of the household’s total hot water (about 1100 kWh).

How Do You Choose the Right System?

Two key performance ratings are Assign to heat recovery systems. The unit’s airflow capacity, measured in cubic feet per minute (CFM), indicates how much ventilation it can provide. The energy recovery reliability, expressed as a percentage, tells you how much heat is recovering from the air before it leaves your home. Before purchasing a system, it is also a good idea to consider the noise level and compare warranties.

What Is the Payback Period for a Drain Water Heat Recovery System?

Drain water heat recovery systems are simplified. Simplify innovations can provide substantial benefits to any home. But, Qualified plumbing and heating professionals must install it. While configuration may be less expensive in new home construction. In existing homes, it can also be install. homes with a payback period of 2.5 to 7 years, according to the US Department of Energy.

All-In-One Heat Pump for Drain Water Heat Recovery

Firstly, The Piranha Drain Water Heat Recovery & Cooling System is a specialized water-to-water heat pump. Secondly, That recovers energy from wastewater and uses it to produce hot water. Secondly, The Piranha has a specially designed evaporator that recovers and transfers energy effectively from wastewater into a refrigeration circuit. That transfers energy directly into treated wastewater.

  • Recycling heat energy from wastewater is less expensive. Energy costs for heating and cooling can be reduce by up to 80% when compare to traditional methods
  • Sewer heat exchangers are environmentally friendly and contribute to long-term sustainability. Using a sewage treatment heat exchanger can reduce the use of fossil fuels. This also curtails the environmental impact by lowering CO2 emissions and carbon intensity. These mechanisms also conserve water that would otherwise evaporate in cooling towers
  • Sewer heat exchangers can save space, giving users more options for building design. Configuration is straightforward and quick too
  • There is practically no limit. Limit to the amount of wastewater. Wastewater that can be produce. Wastewater is a low-cost, localized, and decentralized source of heat. There is no affect in existing seweer system. And, only minor construction is require to gain access to the wastewater.
