Today’s high-efficiency hydronic heating systems rely on optimal water quality to maintain peak performance. Iron oxide sludge, also called magnetite, can destroy water quality and, in turn, affect total system health. This black sludge is an unavoidable result of oxidation inside untreated hydronic systems, and it can cause loss of system efficiency and expensive damage. According to Dr. Neil Watson, ADEY® Global Technical Director, “Nearly 70 percent of circulator pumps returned to pump manufacturers fail due to iron oxide and other water quality issues. Data also show that over 95 percent of debris in hydronic heating systems is made up of iron oxide.”
ADEY, a U.K.-based company launched in 2003, is introducing MagnaClean Micro2™ to the North American market to protect total system health. It features a unique, patented magnetic filtration system that, within minutes of installation, begins to capture and remove virtually all of the suspended iron oxide that collects in hydronic heating systems, restoring optimal water quality. MagnaClean Micro2 is specifically designed for smaller installations, making it ideal for tight spaces.
Designed for ¾-inch copper and ¾-inch NPT iron pipework, the MagnaClean Micro2 is suited for baseboard and smaller residential installations. The compact unit is easily fitted on the return pipe to the boiler/circulator via rapid-fit connectors. It can be installed in minutes and serviced even faster, due to the unit’s quick-release trigger, low-profile drain valve, and built-in air vent.

Bosch Thermotechnology Corp. announced a new line of high-efficiency Climate 5000 Ductless Minisplit Heat Pump Systems, ideal for residential heating and cooling up to 48,000 Btuh, available for single-zone or multi-zone applications. These ultra-quiet, inverter-driven heat pump systems function properly across an extended operating range from minus 13 to 122 degrees F, with indoor sound levels as low as 20 dBA in “silent mode,” which is quieter than a whisper at a library.
These minisplit systems offer quiet comfort with a seasonal energy efficiency ratio (SEER) rating of up to 22, far exceeding the U.S. Environmental Protection Agency requirement of at least 14 SEER for minisplit systems. The intuitive indoor air handler regulates temperature levels in each room, and can be programmed for automatic operation. The “Follow Me” feature uses a remote sensor to heat or cool toward a set temperature based on a user’s location. The unit’s “turbo” feature speeds up the unit when users desire faster, on-demand comfort.
Easy Installation and Maintenance
Installation is simplified with easy mounting of the indoor air handler and quick connection of the refrigerant lines and electrical connections. The unit requires only a three-inch-diameter or smaller opening to run the entire line set. No ductwork is required, making the system perfect for tight spaces or areas where technicians cannot install ductwork, helping to eliminate potentially messy renovation work. Multi-zone system installation is made even easier with the auto-correction function, which verifies and automatically compensates for wiring/piping errors between indoor units and the outdoor section of the system.
The integrated multi-part filter system refreshes and cleans circulating air by reducing potential odors, allergens, viruses and bacteria. Additionally, the system traps dust, pollen, mites and other particles that plague people with allergies. The self-cleaning mode helps remove additional particles as well as moisture via water-wicking Blue Fin technology, thereby reducing mildew buildup.
The Climate 5000 Minisplit Heat Pump Single-Zone Systems are available in four capacities ranging from 9,000 to 24,000 Btuh, in both 115/120V (up to 12,000 Btuh) and 208/230V power requirements. An electronic expansion valve works together with smart inverter technology (variable speed compressor) to achieve the highest efficiency of a SEER 22 rating.
Climate 5000 Minisplit Heat Pump Systems are also available for multi-zone applications. The multi-zone systems enable one condensing section to be paired with two to five indoor air handlers. Multi-zone condensing sections are available in four capacities from 18,000 Btuh to 48,000 Btuh, in 208/230V. For more information, visit www.boschheatingandcooling.com.

At nearly half the decibels and almost twice as fast the new Milwaukee M18 FUEL Surge hydraulic impact driver smoked its predecessor, the M18 FUEL ONE-Key impact driver in a head-to-head tool fight. As I explained in the video above both impacts were loaded with fully charged 5.0Ah battery packs and had new Irwin Speedbor MAX 1/4′ hex chuck drill bits. The 2″X stacked Douglas Fir replicates typical wood framing found in residential and some light commercial structures. The Surge is a quieter, faster and stronger impact driver. I almost never drill small diameter holes with an actual drill. I do this because the impact driver is by my side all the time and the drilling performance is excellent. Carrying another tool into the job, chucking up bits and charging more batteries slows me down and time is money.
Tools tested:
M18 FUEL Surge 1/4″ Hydraulic Impact Driver 2670-22
M18 FUEL ONE-Key 1/4″ Impact Driver 2757-22
Sometimes in order to get a true sense of how a tool stacks up against others in it’s category there is no better way to find out than pitting it against other tools in a head-to-head battle. You may have read a recent review of the Bosch 12V impact driver (PS42) here on The Hub Read more
Sometimes in order to get a true sense of how a tool stacks up against others in it’s category there is no better way to find out than pitting it against other tools in a head-to-head battle. You may have read a recent review of the Bosch 12V impact driver (PS42) here on The Hub and if you have you’ll know there was mostly positive feedback from the three ProStaffers who worked with the PS42 but also a couple notes of contention from myself. Mainly my reservations against the Bosch impact driver were based on my longtime work experience with the Milwaukee M12 Fuel impact driver [2453-22] and its now almost five years at being one, if not the best in the 12V category. So naturally I was curious if my claims of under-powering were true about the Bosch 1/4″ driver.
Some notes on the comparison:
Both impact drivers are built with brushless motors. The EC Brushless motor and drive system puts out no-load rpm numbers of 0-2600 [speed 2] and beats per minute (bpm) of 0-3100 [speed 2]. Typically the telling rating of torque is what most buyers will look at which the Bosch puts out 975 in. lbs.
The Milwaukee on the other hand puts out a class leading 1200 in. lbs of torque with the FUEL motor and drive system. No-load rating for rpm’s are 0-2650 [speed 2] and bpm 0-3550.
Each impact was mated to a 2.0Ah battery pod, and each were fully charged. My personal preference for drilling small diameter holes for water piping and heating lines has me constantly reaching for my 12V impact driver and loading it with the Irwin Speedbor MAX tri-flute self feed drill bit. Each of the impacts were loaded with unused 1′ diameter, 1/4′ hex chuck drill bits.
The test I used was that of a typical residential or wood-frame commercial wall in which I stacked two 2″x8″ Douglas Fir boards in my Rockwell JawHorse vise. With identical bits, fully charged battery packs and identical requirements I started both impacts at the same time in a head to head match. Here is the test:
I never expected that!
To be completely honest I expected the M12 to win. By the numbers it had every advantage but in this case the rpm’s of the Bosch and the smooth motor and drive technology may have been the difference that kept pace with the er hitting Milwaukee. My view on the Bosch has changed slightly from our PorStaff review; I have always maintained that the PS42 by Bosch is well built but now I feel my comments of being under-powered were slightly misguided. I have used the impact for a few months and at times felt it fell short of my previous favorite (the M12 FUEL) but I did know the ratings and hadn’t pitted them in a head-to-head battle. Both are very impressive tools and worth a look without a doubt. A lot of professionals skip the 12V tools and write them off only to insist that anything less than 18V power is not worthy of their time or money. Honestly, that’s a result of experience with old outdated technology and misinformation or lack of new tool education. Today’s brushless 12V tools are powerhouses that get the job done in a lot of arenas. I’m happy we were able to test the Bosch because now I have a second favorite impact on the truck!
