Unbelievable offer

How can extracting heat from the inside air putting it into a domestic water heater tank then pumping it back into the house through a rad to heat air gain you anything? These water heaters have a limited ability to use excess heat in your basement to turn it into hot water cheaper than electric alone (but it is an electric water heater too when you need more) If you have a family of 3 or more forget it, and using it as a zone heating system will cost you in electrically heated water.
It's not a geothermal heat pump it is an air to water heat pump with full electric back up. It extracts heat out of the air and puts it into the water, It does drop room temp. doing so, it will NOT stay constant! Then your plan to put it back into the air as room heat is just an energy losing proposition and it won't keep up without using the electric elements. You need to check out its recover rate and then factor in something like a 4gpm flow and a delta T of 20 degrees to see how much the heat pump won't keep up. They're great for single people or couples with warmish damp basements who run a de-humidifier already.

artificer,

in order to avoid mixing topics I will post more details in my new thread.
Ross raised the excellent question :
And I will show you my very simple device (heat recovery meter) to get the answer for his concern.
In short – I already started to utilize some underground heat thanks to my water preheater:


The design of my water preheater is very simple. A three hundred foot coil was installed into the 55 gallon plastic barrel.

Please wait for more details in my new thread.

Boris. You are not wrong to post that evacuated tubes are more efficient. The issue with evacuated tubes is overheating in the summer, lack of snow melting off the tubes in the winter, and durability.

My business has installed well over one hundred systems and repaired just as many. My experience has me putting the information out there point blank; that the tubes are not for residential applications. Then, they are all coming out of china and are pure junk. My posts are from experience Boris, it is best for people to get this information so they can research and decide for themselves.

Please read my posts again.

sevenmmm,

The ball is still in your court –see post # 19 with your recommendations and my comment to your recommendations.

I can not "buy" your new statement either:

without your real portfolio (web site, links, customers testimonials) as a proof of your experience as a Solar collector installer, especially for the SRCC certified evacuated tub solar collectors from SUNMAXX, Apricus, Thermomax, Thermo Ind.

You know, I have become bored with people who have no credentials. Ok, here is our website:

http://www.greenskyenergetics.com/

Also it is worthy to note my partner, Andy Williams, is a NABCEP Certified INSTALLER in Wisconsin. During the period of time I was marketing and selling 7 days a week, our business installed more heating units than any other in northern latitudes.

This information was given to me by various wholesalers.

Solar heating is all we did, including doing a million dollars in business in the 2010 calendar year. Now that I have burnt out attempting to convince people they should act now - while energy costs are cheap and they still have disposable income - I really don't care anymore.

Don't even know why I started hitting the ball across the net in the first place. I am learning it is far easier to let you people stew in your own ignorance.

One more piece of advice: renewable energy can never replace fossil fuels. Your only hope for a decent lifestyle in the future is to learn how to use less and use it when it is available. Then, and only then, will renewable energy fulfill realistic expectations.

Oh, and you can not beat the 2nd Law of Thermodynamics!

Here is the NABCEP website. The certification doesn't guarantee high knowledge, but does distinguish installer knowledge.

Now I can see the level of your "knowledge" about solar collectors.
Unfortunately, it’s not a rare situation for some salespersons in the areas, related to the technical issues:
-“…SRCC, a non-profit organization whose primary purpose is to provide authoritative performance ratings, certifications and standards for solar thermal products (BUT NOT INSTALLERS!), with the intention of protecting and providing guidance to consumers, incentive providers, government, and the industry.”
From: http://www.solar-rating.org/

You still did not present your portfolio, related to the Evacuated tube solar collectors, especially with evacuated tube solar collectors from SUNMAXX, Apricus, Thermomax, Thermo Ind. WHICH ARE certified by SRCC.
Therefore I would like to ask you one more time - please STOP to misinform people.
And please do not waste my time anymore. I cannot accept your recommendations without payback calculations.

Boris Romanov

The SRCC is an organization that tests for collector efficiency. It does not test collector durability, nor does it recommend how the product should be applied.

Again, evacuated tubes should not be used in a residential setting because the system will always overheat in the summer (the reason being is these are designed to increased temperatures well above the 160 degrees in the solar tank plus will scorch the fluid). They will always be blocked by snow in northern winter areas. And there is not, in my experience and opinion, a single manufacturer that will send tubes without at least one broke per shipment, nor come even close to the 40 year+ durability of a flat plate collector.

So, what I want to know about you, is, how many have you installed?
