Message: I'm evaluating evacuated tube solar pool heaters and had some questions. 1)    Would installations with multiple 30 tube units benefit from using multiple stainless steel heat exchangers? 2)    How resistant to hail damage are the tubes?  3)    Do you have any installations that have weathered hail storms or other severe weather?  Where are they and may we contact them? 4)    In Tallahassee FL we would have to mount the collectors vertically on a due-south facing wall.  The collectors would receive sunlight from about 10AM to 4PM in the winter.  Would that be sufficiently efficient?  5)   Do you have mounting hardware that would facilitate wall mounting vertically? Thanks John

Message: Hello, I have a cottage in Maine that I'm considering heating with solar.  The total space is approx 1300sq ft.  I currently heat the home with a K-1 Toyo heater located in a 400 sq ft room with cathedral ceilings.  A large fan has been installed at the peak of the room to force air back down.  Of course, we have many cold spots in the house since we are using a single source heater.  We also have a very tight addition (300) sq ft that uses a gas heater.  Our total energy use during the winter months are approximately 200 gallons on K-1 and 125 gallons of propane.  We also have a wood stove in the new room and if we are home, use about a cord of wood during the winter months. I'm providing this information to give you an idea of how much energy we need to heat the home in hopes of determining the correct size solar system.   My goal would be to have the solar heating system provide domestic hot water for showers and other hot water needs, which is currently provided by a single 30 gallon electric hot water system, and to install a radiant heat tubes throughout the wood floor system which I have access to in the basement.  I would also like to have some type of radiator in the basement to keep that space above 50 degrees.  I would also like to entertain a backup heat source such as a Rennai hot water heater to make sure I can keep my water supply at the proper temperature for my heating purposes.   I know you advocate that your systems are DIY capable but I may have to hire someone with some experience to provide support. I also am wondering what kind of Federal Tax Credits would be allowed for this type of system.  Your website says 30% but is there a monetary cap to that %. Thanks for your guidance on making the right decision for my needs.

This is inside my unheated greenhouse. I have a 100 gallon insulated heated tank(bottom). I grow tomatoes right above the tanks in the white barrels. Tanks are heated by 3 aquarium heaters. They can heat the tank to 70 F but at night if the greenhouse drops to below zero 32 F.. Water will cool to about 60 F. I would like  a small solar water heater to see what temperatures I can keep the water at. On a nice day (when the sun is out) the greenhouse gets above 80 F for several hours. If this works I have a larger commercial greenhouse available.

Hi:

As you can see I am in the solar hot water biz in Mexico.  I have been spoiled since we are in the tropics and can build direct open loop systems that are PV pumped with flat-plate collectors.  However, I have no experience with heat exchangers.  I am building a 650 gallon in-ground spa and would like to heat it with a "beefed-up" solar domestic system where I will circulate the excess hot water from the solar storage tank through the heat exchanger to heat the spa water being circulated by a 3/4" HP filter pump and will have a salt purification system.

A few questions for you:

1.  Using the SP 155K HE that you sell, do you think 1/2" copper pipe (insulated) would be sufficient for my heating loop from tank to the HE?  Or should I use 3/4".  (I use 1/2" for my solar loops and all of my HT insulation that I have had to ship and import is for 1/2"; so I am hoping 1/2" will do).

2.  I have to pay 33% over my invoice amount for items that I have shipped and imported into Mexico.  Can you give me a dealer discount on a HE and maybe a circ pump for the heating loop to the HE to help offset this?  You would only have to ship it to my forwarder in San Diego.

3.  Any other advice or recommendation on this?

The domestic SHWS is already in place and I am breaking ground on the spa next week; so your prompt feedback will be much appreciated.

Have a good day!  Skip

I would like to avoid some of the increased use of electricity that is used by the spa heater to maintain the 100-105 F degree water temp. 

I also have an extra heat exchanger ( 10 plate ) I thought maybe I could loop that into the house boiler and loop the hot tub into the other side with a 3 way automatic valve and could either tie that into the hot tub thermostat ( if possible) or have an external thermostat.

Obviously I am looking to find the least expensive way with the least amount of work.

Looking for pricing on a system that could supply hydronic heat in floor and domestic hot water.

Good Afternoon,

I'd like to augment my hot tub with solar and have a few of questions about how it would work:

1) Can you give more information about how the heat is exchanged to the hot tub.  Do you submerge one of your stainless heat exchangers into the actual water or do you have to use another pump and use a flat-plate heat exhanger?  If those are both options, which would you suggest?  I live in Virginia and we experience hard freezes so would need a heat pipe system.  

2) If the system was installed with one of your PV powered pumps (instead of a thermostatic controller) is there a concern that the collector manifold might overheat?

3) I have a 600 gallon tub and wonder about the correct sizing?  And with that number of tubes what % can I expect to be solar and how much will I need to rely on electricity?

Thanks so much!

James

I am building  (owner / contractor) a new home with geothermal and solar hot water system.

I would like someone to contact me reference the SWH-5 package system, I am wanting to use it for hot water, under floor heating in the garage floor and supplemental heating with coils in  the forced air geothermal furnace in the return air ducting.

I have questions if this system can heat what I need,   I understand that it has capability of two external heating needs along with the normal house hot water.    My plan is to use another standard 80 gal hot water heater in series (for capacity) with the 119 gal tank supplied with a circulating pump which will also circulate hot water throughout the house and return to the normal hot water tank so I can maintain constant hot water to the other end of the 60 ft. house where the bathrooms are.

I am interested in purchasing this system within the next 3 weeks.

Hi,

I am inquiring about your DC thermal pump that works with the small PV panel.  Will this work with the 30 tube evacuated collector?  We are pumping up about 12' vertical to the roof, will this pump provide enough flow?  This will be a closed loop system. 

The post DC Solar Pump appeared first on Nlsolarheating

I want a pump to circulate water through my solar panels.  I want it to work directly off of my 25 watt solar electric panels - on when the sun is up, off when it isn't.  Pump slowly when the sun is weak, faster when it is hot.

Will you Laing DC 5 pump do that?

I live on 5 acres in North Augusta (100 kms from Ottawa) and I would like to place the system about 200' from the house (less shading and aesthetics). I have a 20 kW forced air electric furnace (expensive). Will a thermal solar help offset my heating costs? Is the distance from the house a big problem? Will the system pay for itself? Is there a local distributor? What type of terms is there for a distributor? If I have a large installation, would it be a viable idea to remove some tubes for the summer months?
