Hi all, Just wondering if anyone has ever tried this product I found on ebay, called a WoodMinder Wood Boiler Monitor? If so, I would appreciate feedback about it. If not, does anyone know of similar products? I have a wood boiler in my shop with a heat exchanger in the house, and I am about to install a propane boiler in the basement to use in the summer and as a back up heat source. This is exactly the kind of device I am looking for that will turn the propane on if it is needed, and will allow me to monitor the boiler (and reduce the amount of time I spend trudging back and forth through all that lovely white stuff!!) I know nothing about electronics.....does this appear to be a legitimate product that could do what it says? Any information you can offer would be appreciated! Thanks! Patti Here is the link for it: http://www.ebay.ca/itm/WoodMinder-Wood-Boiler-Monitoring-System-Wired-/191454406735?hash=item2c9392684f:m:m8yeRu2zICw0p0GGXeoHf6w Below are pictures, installation diagram, and description from the ebay listing. The WoodMinder TWC is the perfect accessory for your outside or inside wood boiler. It won't put wood in the boiler for you, but it’s the next best thing! This is why you should own one: Safety - The WoodMinder let's you know if your wood boiler is approaching a dangerously high temperature. The visual and audible alarm is preset at 200 Degrees Fahrenheit. Convenience - The WoodMinder brings the status of your Wood Boiler into the comfort of your home. You don't need to make repeated trips out into the cold to check on the wood boiler. The WoodMinder’s patent pending design lets you know how much wood is remaining in the boiler and when you need to refill with wood. The WoodMinder has a Fan LED that lights when the Boiler’s Forced Air Draft Fan is cycling; displays the Boiler water temperature and the ON/OFF status of the Gas Valve Relay. Peace of Mind - The WoodMinder will do the minding for you by letting you know if the wood boiler needs attention. You don't need to wonder what is going on with your wood boiler any more. Economy - The WoodMinder eliminates the need to purchase a Gas Valve control Aquastat and saves $$ by eliminating your back-up furnace from coming on when the wood boiler is above the desired temperature. Vacation Mode allows you to fill the wood boiler before leaving for an extended period of time. The WoodMinder will automatically turn on the gas furnace when the wood boiler temperature drops below a user changeable cutoff temperature and turns the power off to your wood boiler after a user defined vacation time delay period after it falls below the cutoff temperature. Flexibility - The WoodMinder is user adjustable to the size of your wood boiler and the way you fill it with wood. It has a user changeable gas valve cutoff temperature and it displays the temperature in either Fahrenheit or Centigrade. Styling - Handcrafted solid oak case with a brushed stainless steel faceplate is about the size of a small alarm clock (7"w X 4.5"h X 4"d). Functional Design - Intuitive controls and displays, Easy to read boiler water temperature, Boiler Fan Status Indicator, Wood Consumption Status in 25% increments, Gas Valve Indicator, Switchable Audible Alarm. Easy to install - The WoodMinder is as easy to install as a thermostat and comes with clearly labeled connections and instructions. The WoodMinder TWC requires low voltage wiring (not included) between the Base/Display Unit and the Wood Boiler and gas furnace. 90 Day replacement warrantee. If interested I can send you additional product information, including installation instructions and operation manual.
