Thank you for this information. I love my boiler west end of Lake Erie propane is expensive here and I’ve had this natures comfort for nine years . The year we bought it gas was five twenty a gallon we burn about eight hundred a year. Paid 4500for a 2year old boiler. Unlimited supply of wood. Thanks carl.
I am confused about something. In Idronics 10, it is several times emphasized that with a wood-fired hydronic system, the load supply should not be more than 120 degrees. However, later, in the section on boiler protection, you advise using a boiler protection valve, or ThermoBloc, to ensure that the return to the boiler should be around 140 degrees or higher, depending on the moisture content of the wood. How can the inflow to the boiler be 140 degrees while the output from the boiler to the heating system be less than 120 degrees?
leslie, the boiler protection needs to be 140 degrees or higher. then you mix the water temp down to 120 or less for use. this limits you mostly to radiant type heaters. this setup with radiant heat is the most efficient to use of the available heat.
Dear Mr. Siegenthaller, Thank you for your interesting presentation video, I found it fascinating, and was wondering if you could answer some questions I have regarding 2 biomass systems I own. In 2013 I installed 2 separate 50Kw biomass systems at 2 separate properties. I am having exactly the same issues with both systems, which seems to be beyond coincidence. When I heat up the biomass boilers, the hot water is not being transferred through the Caleffi 281006 component into the 2000 litre Buffer Tanks. I have had a plumber out to look at the system this morning, he says the pump is working. At the moment, when the system is heated, the Caleffi 281006 component and two of the pipes going in to it are boiling hot, and one of the pipes is stone cold. I would appreciate and advice you could offer as to why this issue may be occurring. Many thanks from freezing North Wales
Good afternoon, thank you for comments. We would like to help you find the reason your system is performing the way you described, but we will need more detailed information. We suggest you to contact our technical support at our U.K. branch for direct assistance: www.altecnic.co.uk/component/option,com_flexicontact/Itemid,20/ Let us know if this could be a way to solve your problem. Have a good rest of the day.
In starting to heat the boiler water with the recirculational boiler loop, when there is no flow to the load, should the main system pump be turned off? (This question refers to minutes 33-34, or Figure 6-4a in idronics 10.)
Great question. Most often wood or biomass boilers are connected to a buffer tank usually 100 gallons or more. So the boiler would maintain that tank at 180F (~82C) or more. The loads would pull from the tank at a lower temperature with a mixing valve or device. That allows the the loads to run off an outdoor reset control and the temperature to the load would vary based on outside temperature. In case you are not satisfied, we advise you to contact directly our UK/IRE Company www.altecnic.co.uk/contact/. Enjoy your day and thank you for your many comments!
Everyone thinking of a outdoor wood boiler needs to watch this.
Great video guys. Thank you for posting this back in the day. I was brushing up on some things and this was great at jogging the old memory.
Love the idronics series. 25+ years as a HVAC Engineer and I'm still learning.😁😁😁
idronics is a wonderful educational resource! Thanks for sharing your experience.

Less bs and more direct info would be great. We are busy out here. Thumbs down.
