Hot Water Recirculation

Quicker Hot Water Means Less Water Waste

Are you looking for ways to minimize your energy costs while still maintaining a high standard of care and convenience? When it comes to hot water, many of us waste litres of water – water we pay for – just waiting for the hot water to come out of the taps. There is a better way and our Calgary Plumbers can guide you!

Hot water recirculation

Right now in your house, water in the hot water lines is rapidly losing energy. When you next want to wash your face, the dishes or run the washing machine, the water in those lines will be dumped down the drain while you wait for fresh hot water to make it from the heater to the faucet. With a hot water recirculation system, a system of valves sends the cooled water back to the heater through the cold water lines and brings fresh hot water directly from the heater to you. It’s more efficient not just from an energy perspective, but it’s also a better way to use water. By recirculating the water rather than just dumping it, homeowners can reduce their water bills while still enjoying a high degree of comfort and convenience.

Benefits of the system

Not only will you enjoy instant hot water, your appliances will too. In fact, with hot water on demand, you will likely see better performance from those appliances that depend on hot water to do their best work. Washing machines, dishwashers, showers – all will see positive impacts from the technology. But the most satisfying impacts may be the ones that hit you in the wallet. With a reduction in water consumption – a goal the City of Calgary is avidly pursuing – consumers will see a reduction in water costs as water is recirculated within the home rather than dumped into the municipal water system. It’s a can’t-lose proposition!

How we can make it work for you

The hot water recirculation system can work in both new builds or be retrofitted into older homes. We love the Grundfos Comfort System, a dependable and high-quality product that has already saved between 12,000 and 38,000 litres of wasted water in the average US household.

While it is more expensive to install a recirculation system on existing plumbing infrastructure, we have to say it’s a LOT cheaper than the tankless water heater option. If we’re able to work with you during the building process, a recirculation system will cost around $350. To retrofit existing homes, expect to pay in the neighbourhood of $950. Whether you’re building your home or hoping to improve performance and efficiency in an existing home, talk to us so we can plan the most efficient, user-friendly and effective recirculation system for you. If your goal is cost-savings, greater convenience and performance or water conservation, the recirculation option is a system that delivers. Give us a call and let’s get started!
