Is the control that operates the pump located in the storage tank? If so the pump not be pumping. A few factors might be needed to solve the issue.

    it's possible that it's located there. They should be wired in to an aqua-stat control of some type. If you know where it's located, turn it to a higher setting to see if it comes on. If not test to see if you have power to the calculator. If you do the pump is NG and needs replacing.

Hi,
You have a problem with your fill valve or pressure reducing valve...it is not uncommon for these valves to plug up or fail to work right.... this valve's job is to maintain 12 psi in your system.
If you do not have enough pressure it will not push the water to the upstairs air handler...
You also will then need to get the air out of the pipes for the pump to work right after getting the pressure problem fixed...

Here is a tip that will help you with that also...

Taco 007 circulating pump stays on even though boiler shuts down


Don't know your specific unit, but in general, heating systems are two-stage devices:

1: Its too cold: the motorised HW/CH valve moved to the required position, and on achieving it, the circulaion pump starts and the boiler is enabled. (The circ pump may start immediately - its not usually important.) The hot water from the boiler circulates through the heat exchanger and/or radiators until the thermostat thinks its target is warm enough, whereupon it disables the boiler, stops the pump and closes/relaxes the valve(s).

2: The boiler is off while disabled. When enabled, it heats the circulating water to a 'high' temperature and seeks to keep it there. If it reaches that temperature, the boiler will cycle on and off as necessary to maintain the set 'high' temperature. (The circulation pump must run all the time the boiler is enabled.) This may be what you're noticing. Additionally, some boilers will run the circulation pump for a little while after being disabled to reduce the temperature if the water in the pipes and boiler.

Your question doesn't say how the pump running corresponds to thee thermostat settings, but if it were stuck on, I think you'd know!

Installed a year-and-a-half ago, problems so far: thermostat replaced on hot water tank within one month of installation, one pump replaced, leaking plug in the front of boiler with Dunkirk rep never


Its probably time for small claims court and a new company to install good equipment. Have a couple different companies/contractors give an estimate and possibly expert advice/witness you would then be able to use in court so you can get reimbursed from a bad company. Hope it all works out.

How to design and calculate the solar heat panel for hot water system for the concentrated 100 nos. staff toilets and changing rooms of commercial building in Beijing. What is the basic and ancillary...


Usually toilets do not require hot water.
Is the plumbing divided into hot and cold water pipes?
If toilets are hooked to hot water, how many flushes and how many gallons per flush per day.
What is the expected consumption per each worker?
What is the latitude from equator, and expected solar input. Further north, and hazy atmosphere reduce input. Beijing has smog I believe.
How often is the solar panel going to cleaned of smog and dirt for maximum collection?
If the area has hard water, then the entire system is prone to sediment build-up and failure unless water is artificially softened.
Solar water heater temperatures can exceed 180 degrees at times. This temperature will damage storage tank that is not made for that temperature.
Most solar water heater systems have pressure regulating valve and expansion tank to accommodate occasional high temperature and pressure.

A good fellow to contact might be at following website:
http://www.builditsolar.com/Projects/WaterHeating/water_heating.htm

Solar collectors are usually connected to a circulating pump, and then the heated water is stored in a tank.
The pump circulates water continually from solar collectors through a storage tank.
This type of system would use ordinary tank-type water heater for storage.
Most of these systems also utilize a back-up heating element inside the tank.

More complicated systems circulate special liquid through spiral tubes inside the water heater.
This type of heater would be an indirect water heater.
Indirect heaters are used for solar collectors, and used with boilers, or any outside heat source.

Amtrol water heater WH-7P gets barely warm water


From what you are saying it sounds like an issue with either a circulator pump or a zone valve. It depends on what type of system you have ... if you have a circulator pump that only runs the Amtrol then that is probably bad. If you have a zone valve system then it is probably the zone valve if you still have heat for the rest of the house. If you have no space heating then it is probably the circulator pump.

Central heating circulating pump


The vent pipe should be in front of the pump so that the pump pushes towards the vent pipe NOT sucks from it. I hope this vent pipe is part of the heating system and not of the hot water
Pumps like to push not pull and therefore it is better if the pump is located further down - say at the bottom of the cylinder or lower.
With an indirect cylinder, the hot water & heating are separate circuits and are not and must not be interconnected. You will need a separate pump for the hot water which should be taken from the hot pipe coming out of the cylinder. You may get vacuation in the cylinder - then you will need an Essex or similar valve to replace the hot water outlet connection
By the way - The pressure at any hot tap is directly related to the height difference between the tap and the header tank in the loft [thus a shower downstairs feels stronger than one upstairs]

Taco circ. should be bronze in color for domestic applications. If it is green, it's wrong. Average temp for hot water should be 120 degrees. Overheating of circulator may be the cause of premature failure.
