jIf you are a contractor sometimes you make contracual arragements with people who agree to pay you by progress payments and everytime they are suppose to pay you a certain sum they take advantage of their finacial situation and always try to short you money so you can’t finish the job properly. Mr. Prashant Patel is a prime example. I suggest that no contractor should work with someone like this because the person will give you so many problems that you will never be able to complete the job and make both parties happy.

Look here for an alternative that apparently is better. I uses no pumps just pressure.

Thanks for the info Chester. It answers Gennaro’s question or “confusion” with the cold water entering the return line.
With a check valve installed the cold will not be mixing back into the warm return line and will also prevent the warm return heat mingling with the supply (cold).

carroll;
In brooklyn ,the price of electricity is so expensive,that we do not use it commonly to heat water.The units are natural gas fired.

Genero,
A btu meter is a good idea to install,but wait after the solar part is done ,so that the solar input can be coupled with the boiler and will be able to show in real time and on this site the hour by hour performance.I will talk to you personally about it.Remote monitoring.

This is chester replying to \"sam\" in michigan.The domestic hot water return in the diagram is mixed with the incoming cold water to increase the incoming water temperature in the tank or the boiler so that the boiler will be on for a shorter time to make hot water than if normally the cold incoming water entering the tank,without a return;the boiler will take a longer time to bring the water to the same temperature.
Another advantage is the readily available hot water at the fixtures without wasting water.A check valve is placed at the junction of the cold water and the hot water return.The circulator will be set-up to be timed and resond to temperature difference on the line.

Sam,
To answer your questions. I’m still not 100% knowledgeable in the hot water water mixing method. From what I understand yes the two mix together and enter the boiler in one pipe. And yes there are check valves.

I would like to monitor the energy used by the pump. I’ll probably do it manually using the KillAWatt watt monitor.

Carroll you write funny. You write just like the writing on Dr Bronner’s Magic All In One Soap bottles.

Some questions I have about your hot and cold mixing question:

Does the boiler have more then one inlet or just one inlet the hot and cold have to mix prior to entering boiler?

Are there check valves on the cold and hot return lines before the two mix together and enter the boiler?

Will you monitor the power usage on your pump to determine the actual energy usage to see if it is “tongue” worthy.

Keep up the good work.
