A thermosiphon is a natural circulation system that creates hot water in homes by providing a return piping run to the hot-water tank. This system can be used to control temperature in greenhouses using natural and forced ventilation, evaporative cooling, and artificial heat. To heat a greenhouse for free, consider using a 1200 gallon per hour recirculating pump or geothermal systems.
A thermosyphon loop can be set up without pumps by linking all storage in series on the bottom of the tank and pulling cold from the bottom at one end. The extra mass of water will retain bacteria, and most systems with an actual pump have timers that can be adjusted.
For heating plant beds with warm water, use 3/8″ PEX pipe connected to a Noritz gas/LP instantaneous tankless water heater. For about $2,500, you can install a hot water heater and hook up a system that pumps warmed water through piping left on the ground. The goal is to allow heated water to rise into your tank, causing circulation.
The amount of heat needed to store depends on your home’s climate. A remote bulb thermostat is the most common control, which senses soil temperature and activates the circulating pump when heat is needed. However, it is important to avoid using a greenhouse without direct sunlight and to consider the potential high costs associated with greenhouse heating.

Should a circulator pump run continuously?
The hot tub circulation pump is a vital component in the spa’s plumbing system, ensuring efficient water circulation and efficient heating. It pushes water through heating elements, preventing stagnant pools and ensuring even heat distribution. The pump also reduces heat loss by ensuring consistent mixing of warm water, preventing stratification or cooler temperatures at the top surface. This active circulation minimizes heat loss and maintains a consistent temperature, reducing waiting times for the hot tub to reach desired warmth.
The continuous operation of the circulation pump contributes to easier hot tub maintenance and reduces the risk of biofilm. This ensures optimal water circulation, heat distribution, and quick heat-up times for relaxation. The hot tub circulation pump provides the convenience of quick heat-up times and spontaneous relaxation sessions, allowing users to enjoy their hot tub without waiting for it to heat up.
How can water flow without pump?
The initial level of the water source was higher than anticipated, and a video was produced to document this setup, which will be included in the description.
Does a hot water recirculating pump run all the time?
Most common circulator pumps operate continuously, causing heat dissipation in pipes and requiring the water heater to work harder to keep the water hot. This combined energy use makes these pumps some of the largest energy hogs in homes and buildings. Some pumps use timers to run at specific times of the day, but these are only marginal improvements.
There are other more efficient models that save water while using only a small fraction of energy, such as pumping on demand when hot water is needed or using advanced control solutions in large apartment buildings. These smarter circulators can save more money on your energy bill, adding to the water bill savings. Energy Solutions reports that these energy and water savings pay back for the cost of the pumps within 2 to 6 years, considering they can last for decades.
What is a bypass water pump?
Temporary plugs are utilized to facilitate the positioning of the suction manhole in an upstream direction and the discharge manhole in a downstream direction.
Where should a hot water recirculating pump be installed?
A hot water recirculation pump is a device that facilitates the continuous circulation of hot water from the water heater to the sink or shower, thereby ensuring its immediate readiness for use. The device functions by means of a circulation system that transports water from the water heater to the sink or shower, thereby guaranteeing the continuous availability of hot water when required.
Where is the best place to install a recirculating pump?
The cost of installing hot water recirculation pumps depends on several factors. The location of the water heater, the existing electrical system, and the number of pumps required are all important factors to consider. If the existing water heater is in an area that doesn’t allow for the installation, it may require additional plumbing or wiring. If the electrical system needs to be changed, it can add to the project’s overall cost.
Burgeson’s offers both plumbing and electrical work, eliminating the need for hiring another contractor. Additionally, larger homes often need a second water heater, which can increase the installation cost due to extra time, labor, and parts like shut-off valves.
Is a hot water recirculating pump worth it?
Hot water recirculation pumps are a valuable home improvement that offer convenience, water and energy savings, and environmental benefits. They come in various types, including demand-controlled, timer-controlled, and temperature-controlled pumps, catering to various household needs. The installation cost of a recirculating pump can vary depending on the type and whether the installation is done by a professional or a homeowner.
On average, professional installation costs range from £400 / $500 to £1, 200 / $1, 500. Therefore, considering your hot water usage patterns and specific requirements is crucial when choosing the best system for your home.
What does a hot water circulation pump do?
A hot water recirculating pump is a device installed on a water heater that circulates hot water from the water heater through pipes and back to the water heater, ensuring quick availability at faucets and showerheads. This method saves energy and water, and provides more immediate hot water at fixtures. The speed at which a recirculating pump can send hot water to a shower depends on factors such as the pump’s size, the distance the water needs to travel, and the flow rate of the shower head.
Typically, recirculating pumps have a flow rate of around 1-2 gallons per minute, which can vary depending on the specific pump. A higher flow rate of the shower head also affects the speed at which hot water reaches the shower. Recirculating pumps are recommended for energy savings as they reduce the time it takes for hot water to reach fixtures, as traditional plumbing systems require continuous heating of the water in pipes.
Do you need a recirculating pump for a water heater?
A recirculation pump installed near a kitchen sink or shower can improve hot water speed and efficiency. It also helps prevent water waste by cutting back on the daily water waste of over 30 gallons due to waiting for hot water to reach the faucet. Tankless water heaters are a popular choice for households looking to reduce energy consumption. Even with professional installation, homeowners can make a quick return on their investment due to reduced water and energy costs. The average homeowner can recoup their initial investment in just a couple of years. Overall, a recirculation pump is a cost-effective solution for a better water experience.
Does a hot water recirculating pump use a lot of electricity?
Hot water recirculation pumps consume a significant amount of energy, consuming around 200 kWh of electricity annually. The average electricity price in the US and Canada is $0. 13 per kWh and $0. 17 per kWh, respectively, making the cost of running the pump between $26 and $34 per year. Even with the exaggerated expected water savings of 11, 000 gallons, the electricity cost to run the pump would still be more expensive than the average water savings for most of the country.
Additionally, there is no payback period for the $200 to $250 price tag of the pump and plumbing installation fees. Some models of hot water recirculation pumps come with timers that allow for reduced electricity use during high-demand periods, potentially reducing annual electricity use to 40-50 kWh or less than ten dollars per year. Therefore, hot water recirculation pumps may not make economic sense for most homeowners, as the electricity cost may outweigh the expected savings from reduced water bills.
Does a hot water system need a pump?
Circulating pumps are essential for hot water systems, as they can save time and reduce water waste. They are similar to energy-saving LED lights, costing between £160. 30 for small-scale home pumps and £7, 429. 50 for large-scale pumps. However, these pumps use minimal electricity, often less than 100 watts, and can save up to 70% of electricity compared to D-label pumps.
Recirculating pumps have a long lifespan, often lasting up to and above 15 years. However, failure can lead to issues like no hot water, noisy pipes, or leaks. Over time, recirculating pumps can cause wear on pipes due to constant water flow, but this is usually a long-term concern. Proper installation by an expert can mitigate these issues.
In summary, circulating pumps are a cost-effective solution for hot water systems, providing efficient and reliable hot water. They can save up to 70% of electricity compared to D-label pumps and offer a more efficient and reliable solution for hot water systems.
📹 Circulating pump: What is it & why is it important?
In this video, we’re going to talk about the circulating pump, why it’s important and what circulating pumps are used for.
Endless Hot Water for Your Home (No Electricity). This is a very cool instant hot water heater that can run off of regular cooking/vegetable oil and generate heat/hot water for your home for up to 24 hours running on a single small tank of oil. This instant hot water heater only weighs three pounds. It is very light weight and can be carried in a backpack and used in a case of power outage or emergency. Also, any water can be boiled down so that it can be used as drinking water in case of water outage. In case it is used indoors, an exhaust pipe has to be installed to vent the fumes outdoors so that the heat radiation can also be used as a source of heat. For the sake of the article, we used a small fountain pump, but a heat pump may need to be used that is designed to handle boiling water temperature.
Was thinking of a bigger design that runs off an indoor woodstove, only issue I could think of is how all my pex and pvx lines would need to be swapped for copper to handle such hot water flowing through the lines. Though there are other designs used for this to work, like a system that mixes the how water with well water from the blatter right after it comes out of the hot water reservoir so it brings the hot water back down to a normal hot water heaters temperature range, so all the pvc(plastic) lines already installed can stay. Plus to have pressure to the hot water system it needs to be tied together with the house main in some kind of setup. If already using firewood to heat our homes during the winters this would give us free hot water all winter. All year if you want to have an outdoor woodstove for summers. Starting an indoor woodstove for hot water when it’s 90F outdoors sounds like a bad idea 😂
Fantastic work, great article, as usual. Just a tip, it’s just a “water heater”. “Hot water heater” is a redundancy, sort of like “ATM machine” Again, awesome job. As someone else commented, you really could go into production with your projects, you have the website traffic, and people would buy your stuff.
I think you may be able to delete the pump. With copper tubing..Go from bottom of hot water reservoir to flame coil ..that discharges to the top of the hot water reservoir.. the heat causes pressure and that will push your fluid..like a coffee maker. I think.this is the thermosyphon effect?. U will probably have slugs instead of Constant flow. But u may be able to eleimate the bottleneck of the upper pump te.perature limit…speaking of bottleneck, it may be a good idea to put a valve at the bottom of the hot water res..limit the amount of water gets to the coil…allow u to adjust how much ur heating with constant flame.
I was thinking about doing something similar with this but at a smaller scale using a candle inside of a tin can with a little door so the candle can’t fall out and the copper coil inside as well, using a portable cooler as the reservoir to hold and keep the water hot longer and attaching the copper pipes to the water pump in the same way but add a heater core from a car with a fan behind it for heating a room in the house! Thinking it should work and shouldn’t get any hotter than 150F might even be less but as long as it’s putting out 110 120F that’s plenty hot enough to heat a room in no time at all!
The design is great however I would improve upon it and only one way Have a secondary water tank that sits above with a water line on the top of the tank and a waterline on the bottom of the tank the top one runs to one into the heat exchanger the bottom one runs to the other end of the heat exchanger and what happens when you do this as you will get a water rotation that works with gravity as the water heats up the hot water rises to the top line in the cold water is pushed down through the bottom line and then you would just run a water faucet off the bottom of the tank so you can keep the heater outside and have the tank inside
Just a thought but from a log burner you have a flue to roof. Could a coil like this shown in a flue be placed so that the secondary heat leaving the flue heats the water into a water tank next to the log burner. Is that a convection system? Then whilst using the log burner you have a dedicated hot water system?
One of the significant advances of human civilization has been the discovery of “blue flame”. This is when you mix fire with enough oxygen that the flame turns blue and this is when it burns very efficiently. Simple stovetop gas burners have air mixing inlets that lead to a blue flame. Block said holes and the flame is yellow and very sooty. Cool invention though!
Now I want to see one with a potable water tank and recirculation pump to get the stored water up to temperature for a shower and an easy way to ignite and turn it off. I’m thinking of using a spark plug attached to a battery and a button to start it and use a sealed manual damper on the intake and exhaust. For bonus points use electric dampers and have them open when the pump turns on and close when it turns off.
I love it thanks. Did we know that just some magnets rotating under that copper coil just as it is would heat it up. I’d love to see a article of somebody make it. I’ll buy the instructions for a hun if it’s in detail and can hook it up to my existing system somehow and shot off my gas. You’ll be doing the world a favor and sticking it to the slave rulers
Calculate the heat transfers 1. to bottom of pot and 2. to surface area of small pipe the RATE of hot water production was not shown and not that high either. see how long it takes to heat 5gal bucket from 40 to 95f, also temp control is a huge problem. Most heat xfer is not in the coil but at the top plate Also pump is unneeded as it will thermosyphen
I wonder if there are any clever humans out there, thinking about ways to make old coffee makers, which are often found at thrift stores, for low money, who are thinking of ways to make appliances like these work in some similar ways to the ideas in this article. How about clever people who can figure out how to make lithium battery powered appliances. I once wished there was a battery powered mini microwave, that I could have taken to the job site, when I worked carpentry in the winter time. I guess there was a mini microwave on the market at one time. More focus on units that can heat and boil which can function reliably on re chargeable batteries. I feel confident it can be done.
Your invention needs to look at cost, ease of use and accessibility. If you could somehow connect to your main water supply and have it auto switch on when the hot water tap is opened then you may have a good invention that could compete with gas geysers. I’m sure with a working proto type of that you’ll be able to get a good kick starter up and running
No electric but 12 volt motor .. it could actually run without the 12 volt motor .. that would be useful to know .. if you just don’t have any electricity.. old radiators systems used to work by gravity in the old days, just for the fact heat rises and cold drops down, creates a circle .. u know what the pump does
