Caleffi has published this technical journal to help installers with design and piping. We show 8 different piping options with pressurized and...
The Habitat Re-store in Springfield MO has a pile of insulated pex, single and double tube style 25'- 50' pieces. $1.00 per foot your choice! hr
Filling and purging a new or remodeled system can be a frustrating process. To be able to "push" air from a piping system you need enough water flow...
Here are a few add on for air vents. On the left is an anti- vacuum cap. If you have a problem with air re-occuring it may be getting sucked into...
Here is one concept we will show in I-dronics 10. This provides all the HXers outside the tank, and provides instant DHW with a tankless gas or...
From friends on the floor of the ISH show in Germany today. About 5000 Euros to consumers over there. hr
This shows the heat transfer with and without plates. Notice the peaks to valleys in the direct tube staple up. This is across an 8" wide spread,...
I'm thinking about dropping some chains down the tubes in my older EKO 40, as others have. I think this "dog leg" hook will be a good way to rattle...
Here is the latest change to my system. This 50 gallon prototype tank has six 2" FIP ports on the sides and three 3/4' on top. It acts as a...
out of VT. Looks like they have done a lot of TRYNSYS energy modeling on this system. They claim R80- 100 insulation values!...
addressed in a technical journal. We have begun work on an issue dedicated to hydronic for solid fuel boilers. We have engineers here in the US,...
hope the gas petal doesn't stick.
This attaches to some of the solar controllers, via a two conductor wire. It displays solar, or boiler temperature, tank temperature, and KW...
this is the data logger that comes with the solar control I showed in another post. Plug it into a USB port and slip the SD card into it. Now you...
This piping would allow one variable speed controller to protect either boiler. The control targets the tank temperature ay say 180 °F . If the...
I have been running my system with a delta T function on the boiler pump this season. The control has a data logger built in and I will post some...
Some changes and upgrades to my wood/ solar/ LP system. I reduced the piping from the "Primary Secondary" sticky above. There are always some trade...
I've redone my control logic a half dozen times. I think I now have a completely hands free logic. I may eliminate the tekmar 155 differential when...
This control has 7 outputs (120V) 3 are variable speed triac relays, 3 relay outputs are standard, one is a dry contact. The V-bus allows a laptop...
when you start adding fuel burning appliances inside your home or shop remember they need air (O2) to burn properly. They will do everything to pull...
