It doesn't sound like you are done yet. Your PEX loop will have higher head loss than the rads and the old circulator might just not have the head pressure required. Now, that doesn’t mean that you’ll have hot water circulating 24 hours a day through that line. Not sure how long this has been doing this, but I just noticed that the Taco circulator pump on my home oil boiler is constantly running even though *none* of the 4 zones (3 heating and 1 domestic hot water tank) are calling for heat.

Design your hydronic heating system to not require on'off demand of the pumps. When you installed the PEX, what other modifications were made? The pump works like any centrifugal pump, with the rotating impeller building up the velocity of the fluid as the fluid passes along the impeller vanes. And second, if you believe the pump is likely to fail (your history tends to point that way) consider purchasing the pump now and having it available; last year I came home from work, notice it was already negative 15 F outside and falling, I determined that a motor had failed in the heating system, and that might have stocked a replacement was closed. Check yours in fall to be sure it remains in good working order. This may not have been a problem with the radiators as convective flow probably did a lot of the work. Then the high velocity fluid is converted into high pressure fluid in the diffusion portion of the pump casing. As long as the central heating system is properly installed and maintained, you can expect the pump to last for a long time. The problem could be a lot of things and the circulator could be one. I'm wondering if the circulator is not doing its job and that is the problem. Almost all recirculating pumps these days will have a timer on it so it only starts the recirculating at the hours when you’re likely to need the instant hot water.

Like someone else said, buy a flange set with built in valves. One thing for sure however, is that at some point in the life of a spa or hot tub, a circulation pump will develop problems. Zone valves as used in home hydronic systems are usually electrically powered. Although, in a typical configuration, they each shared 50% of the work load. It features a unique cartridge design that’s completely field serviceable plus a self-lubricating system that’s virtually maintenance-free. There’s just one circulator? Cookies help us deliver our Services. . Pump impellers do ware out and the water will just bipass internally.

By using our Services or clicking I agree, you agree to our use of cookies. Usually, they continue for more than 10 years, with a duration of 20 years or longer. How hot water circulation systems work. Circulator pumps can stop working for several reasons: a … Did your service man check to get air out on the second story and make sure the feed value is putting water into the system so you can get enough pressure to get air out and make the upper story work. Replacing a broken or noisy circulator pump on a boiler, central heating or hot water hydronic system. How Long Do Recirculating Pumps Last? Are there balancing valves? The pump does not come with mating flanges, and those have to be purchased separately ... to leave these on as long as you can. You more than likely have a problem with the way the Pex was installed. Is there a mixing valve serving the PEX? I'm afraid of the pump possible failing while I'm gone and end up with a mess. Is so, how’s it controlled? Is there any way to tell how well it's working without taking apart the piping? It has 3/4-inch pipe thread connectors, and you place it in the hot water line next to the water heater or near the fixture that needs the hot water. This ^. I recently replaced some of my cast-iron radiators with underfloor Pex heating and am having trouble getting flow through the Pex (yes, I bled the lines thoroughly). This Fall, Tune Up the Engine That Drives Your Hydronic Heating At the heart of a hydronic heating system is the circulator pump. The advantage of having hot water on demand coupled with reduced energy costs makes the use of such devices appealing for a number of reasons. As long as the central heating system is properly installed and maintained, you can expect the pump to last a long time. Circulation pumps tend to last 5-10 years, although your mileage may vary. I recently replaced some of my cast-iron radiators with underfloor Pex heating and am having trouble getting flow through the Pex (yes, I bled the lines thoroughly). In large commercial installations, vacuum or compressed air may be used instead. If you get more than 30-years out of your central heating pump, then you have done extremely well (Give your central heating pump a pat on the back). Not every pump is created equal. In-floor typically has lower water temperatures than rads. As long as your central heating system is properly installed and well maintained, you can expect the pump to last a long time. I like to say that even if a pump fails it does not mean that a better pump exists. As long as you want it to (by maintaining it properly).

We had a fairly mild winter last year but I did burn only 1/2 of the fuel oil used to heat my house compared to previous years. Did you install a true radiant manifold? The power of the pump is enough to cause the water to travel right back up to the boiler from the pipework. The problem with this option is, due to hot and cold water sharing the same pipe, the water from the cold faucet may be lukewarm or take time to get cold, especially if you have a swamp cooler. Hot Water Circulation System (highest install cost, highest operating cost, greatest hot water comfort, no influence on cold water comfort). A boiler's circulator pump is used to remove hot water from the boiler, and then pass it into heating devices such as the radiator or a convection pipe system. Is the system zoned?
