We have changed the standard Aquastat on the boilers from the Honeywell Electronic unit to the HydroStat Model 3250 Plus with built in low water cutoff. When existing stock runs out the new units will be shipped with the new control. More information is available here: http://www.hydrolevel.com/pages/pdf_files/hydrostat_3250_instructions.pdf If you are interested in purchasing the new Aquastat for your existing boiler please contact us.
The Outdoor boiler production model has been delayed by a supply issue with the panel manufacturer. We do not want to offer these units for sale until all issues are resolved. In the mean time you can purchase an AA220 and install it in a shed, we will assist with any questions you may have since many of our customers have already done this. We apologize for the delay and are working diligently to resolve the issue.
We are working on an outdoor boiler that is based on the AA220 unit and will be completely self contained with optional automatic ash removal and 2, 4 or 6 ton remote storage with automatic feed. The first prototypes will be available in late August and will look similar to the sketch shown below. Please contact us if you are interested in helping us test this new design as one of our first customers to purchase one.
The 60 CFM Combustion Fans found on the WL110 and AA220 Boilers have been found to be undersized in some installations, the symptoms are flames coming off the coal bed at full fire that are only 8 to 10″ tall. This issue first appeared during the colder weather in January. Research using the 60 CFM fan showed that it needs to be replaced by a 65 CFM fan on some boilers (to ensure no issues we are shipping the larger fan with all new Boilers from now on). The larger combustion fans bolt on in place of the old fans and need to be adjusted for proper over fire draft (the procedure is found here). If you feel you have a under performing Combustion Fan contact your dealer and we can determine if you need a new larger fan.
