    I was searching for prices and a supplier, came up frustrated. Does anyone have a link? I seem to have some circulation problems.

    Also New Horizon Corp has a Danfoss Valve, on ebay check Marc at "Passion for fire and water" search Thermovar.

    I am looking for a Thermobac, LK822, p/n 181110, low opening pressure check valve to use in my piping for natural circulation from a wood boiler to a storage tank for a low of power dump zone. Seems that they are all in Europe! and shipping is a killer. Any Suggestions??

    I think the premade loading units are the way to go, but I have all the components except the check valve. I could use a brass swing check but I am not sure the tank has the height to open the swing and get the max flow. Any restriction in a natural convection circuit is an issue.

    thanks TJ
