The assumption in this running cost estimate model is that your building has high-quality insulation materials installed in the walls, roof, and floor.

In the video above, This Old House plumbing and heating expert Richard Trethewey explains how a recirculating pump works and its benefits. Below, we’ll recap these details and answer some common questions about hot water recirculating pumps.

Technological advancements have made recirculating pumps smarter and more efficient in recent years. Modern systems can learn your household’s hot water usage patterns and adjust operations accordingly. Some of these systems integrate with home automation platforms, allowing homeowners to control and monitor their recirculating pumps via smartphone apps.

The efficiency of the underfloor heating system itself plays a crucial role. The efficiency determines how effectively it converts electrical energy into heat. Modern systems with advanced controls and high efficiency like Coldbuster use less energy to achieve the desired warmth.The assumption in this running cost estimate model is that your heating system is running efficiently at all times.

Some systems can use existing cold water lines as the recirculation line, simplifying installation. These solutions often involve a pump at the water heater and a valve at the farthest fixture to move heated water as needed. This method reduces the need for extensive plumbing modifications, but cold water still recirculates back to the heater instead of being wasted down the drain.

How does ahot water recirculating pumpwork

Installing a hot water recirculating pump benefits the environment by reducing water waste and optimizing your energy use. However, it’s crucial to use timers and aquastats effectively to ensure you’re saving rather than expending extra energy. Also, consider the energy source for your water heater. Homes using renewable energy sources will find even more environmental benefits.

Point-of-use pumps are installed at specific fixtures, as Trethewey shows with the system in the bathroom vanity. These are easier to retrofit in existing homes but may not be as efficient as full systems. They’re convenient for homeowners who want instant hot water at particular locations.

The assumption in this running cost estimate model is that your heating system is designed with zoning capabilities for customised temperature control.

Installing a hot water recirculating pump requires careful planning and execution. Here are some key factors to consider:

Integration with home automation systems allows homeowners to set schedules, monitor energy consumption, and receive maintenance alerts. These features make it easier to manage the system efficiently and ensure continuous optimal performance.

Proper maintenance extends your hot water recirculating pump’s lifespan and keeps it operating efficiently. Here are some maintenance tips to keep your system in top condition.

A duty cycle for electric underfloor heating represents the percentage of time the system is actively heating versus its total operational time. After the floor reaches its set temperature, the system cycles on and off to maintain it. The calculator factors this in and assumes a 50% duty cycle.

Are you tired of waiting for hot water to reach your faucets? A hot water recirculating pump might be the solution you’re looking for. This device can save time, water, and energy by making hot water readily available at your taps. We recommend professional installation for this project, but it’s helpful for homeowners to understand how these systems function.

The design of the heating system, including the layout, spacing, and type of heating elements, affects heat distribution and overall efficiency. The size of the room in relation to the heater’s capacity is crucial. An appropriately sized heater ensures efficient heating without overworking the system.

Consider the above factors and your budget to help you determine the best recirculating pump for your home. We recommend consulting a professional to make an informed decision. A consultation can also address any concerns you may have about installation, maintenance, and potential energy savings.

We recommend having a licensed plumber install a hot water recirculating pump for you. As Trethewey says, “A recirc[ulating] line improperly controlled could be one of the biggest energy wasters in the whole building.” Do-it-yourself (DIY) installers could end up accidentally wasting hot water and overworking the water heater. A professional also knows how to comply with local building codes.

Different floor coverings have varying thermal properties. Materials like tile and stone conduct heat efficiently, while carpets and wood may require higher energy to achieve the same comfort level.The assumption in this running cost estimate model is that your flooring material is chosen with consideration of its thermal conductivity and compatibility with the heating system.

Full recirculation systems require a dedicated return line from the farthest fixture back to the water heater. While these systems are effective, they can be challenging to install in existing homes due to the need for additional plumbing. However, they eliminate cold water in the lines, providing the easiest, most efficient path for getting hot water from your fixtures.

The assumption in this running cost estimate model is that your heating system is designed and installed by experienced Coldbuster installation professionals or other suitably qualified professionals to ensure optimal performance and energy efficiency.

The assumption in this running cost estimate model is that your ceiling heights are standard (2.4 to 2.7 meters) to maintain optimal energy efficiency and minimize excess energy use.

Higher ceilings result in larger volumes of air to heat, which can increase energy consumption. Rooms with standard ceiling heights are more energy efficient.

Hot water recirculating systems provide instant hot water at your faucets, eliminating the need to clear the pipes with cold water. This is particularly helpful in larger homes or buildings where the water heater is far from the point of use.

With a properly functioning recirculating pump, you should have hot water almost instantly when you turn on the tap. The exact time may vary slightly depending on your home’s plumbing layout and the distance from the water heater, but it should be significantly faster than without a pump.

Draughts from poorly sealed windows and doors, as well as other gaps, can lead to heat loss and increased energy consumption. The type and quality of windows and doors significantly impact heat loss and gain. Double-glazing and well-sealed frames reduce draughts and improve thermal efficiency.The assumption in this running cost estimate model is that your windows, doors, and other potential gaps are well-sealed to prevent drafts and heat loss.

The efficiency and cost of the electricity used for heating directly impact running costs. More efficient energy sources and favourable electricity tariffs reduce overall expenses. Electricity prices vary by provider and plan. Choosing an energy-efficient tariff and monitoring peak and off-peak rates can help minimise heating costs.

The local climate influences heating needs. Colder outdoor temperatures increase the demand for indoor heating. Regions with milder winters require less heating and would therefore typically have lower running costs compared to areas with harsh winter and cold conditions.

Consistent and predictable usage patterns help in planning and optimising energy consumption. Irregular or excessive use can lead to higher costs.

The total time the heating system is operational impacts energy consumption. Running the system only when necessary and using programmable thermostats to create heating schedules can optimise usage.The assumption in this running cost estimate model is that your heating is running only when necessary and optimised accordingly.

The overall energy efficiency of a building, including factors like construction quality, age, design and energy ratings, all affect its thermal efficiency and hence impacts heating costs. Older buildings may have more heat loss compared to newer, energy-efficient constructions.

Coldbuster’s radiant floor heating systems keep heat in the right area – heating people in the room, not the ceiling. A heat that falls from ceiling-height is normally cold by the time it reaches the floor, a flaw in systems with less even heat distribution. Keeping your feet warm saves energy and provides the ultimate in comfort. Warm feet will spread that heat and good feeling to the whole body. You don’t get that stuffy head warmth and cold feet sensation with Coldbuster radiant floor heaters, as they evenly warm the area from the ground up.

Please note that the factors and the assumptions that underpin this Running Cost Calculator mean that results should only be used as a rough guide, as conditions (some of which are listed below) can vary greatly.

The temperature set on the thermostat directly affects energy usage. Lowering the thermostat temperature by just a few degrees can significantly reduce running costs without compromising comfort. Programmable and smart thermostats can optimise heating schedules, reducing energy use during non-peak times and enhancing overall efficiency. Setting the thermostat to an optimal temperature (e.g., 20-22°C) during occupied times and lowering it (or even better turning it off) when not in use can significantly affect running costs.

The assumption in this running cost estimate model is based on average climatic conditions specific to the region in Australia where you are located and where the system is installed.

No, a hot water recirculating pump should not run continuously. Using a timer or smart controls to operate the pump only during peak usage times can significantly reduce energy consumption while still providing the convenience of instant hot water when needed.

While a hot water recirculating pump does consume some electricity, modern efficient models used properly (with a timer, for example) can minimize energy consumption. The energy savings from reduced water heating needs can often offset the pump’s electricity usage.

Proper insulation reduces heat loss, making the heating system more efficient. Effective insulation in your floors, walls and roofs will help maintain the desired temperature with less energy consumption. Better insulation helps retain heat within the room, minimising the energy required to maintain comfort.

The assumption in this running cost estimate model is that your energy source is cost-effective and the electricity tariff is optimised for heating needs.

The recirculating pumps themselves can be included in several different systems that work for different home layouts and hot water needs.

A radiant floor heating system is invisible, with no grills or panels. It is extremely safe as there is no exposed heat source to touch or get burnt from. The system evenly spreads heat across the floor area, and as it rises it provides an even, comfortable warmth to the room. Because of this, radiant floor heaters do not need to produce as much total heat to create the desired room temperature. There are also no dust or allergens blown around the room, as there are in forced air systems – particularly useful for allergy or asthma sufferers.

Electric radiant floor heating has many benefits when compared to forced air systems, convection radiators or reverse cycle air conditioning. The manner in which warm air circulates through a room determines how effective a specific heating system is. If all the heat is going to the ceiling then you are losing a lot of the effect of the heater, and require higher output temperatures to feel the effects. Obviously, this is not very energy efficient. With Coldbuster’s radiant floor heating systems you can achieve comfortable warmth as part of a cost-effective, energy efficient solution.
