  • 8/25/08 Monoflo Tees

    • Monoflo Tees are usually installed on the return side of heaters with the middle portion of the tee facing upwards. Looking at the tee this way, the left side is the where water enters, the middle (on top) is where air escapes, and the right side is the outlet. Sizing is done with the first number representing the inlet and outlet and the second number representing the middle. Monoflo Tees
  • 8/22/08 What is a sillcock?

    • A sillcock is a type of hose bib (or bibcock) with female threads where it connects to the house. The back of the sillcock is flared, so that when it is screwed into place, the flared part covers the hole in the wall where the pipe comes through. Sillcocks are used for outdoor faucets, gardening, watering lawns or washer hook-ups. Sillcocks
  • 8/21/08 Honeywell Aquastats and Wells

    • On the side of your Honeywell Aquastat is a copper sensor. Vertically mount the Aquastat, slide the well over the copper sensor and fasten with a coupling or bushing. Emerge the well into the boiler water- the copper sensor and copper well allow for the transfer of heat but not the transfer of water. Regardless of the type of boiler you have, an Aquastat acts as a safety device for measuring the temperature and assuring that it does not go too high.

    Honeywell Aquastats with different model numbers can serve different functions, but all Aquastats require a well. In some cases, the Aquastat will turn the boiler on and off, and some check the water level, temperature, and/or pressure. Make sure that your Aquastat meets the specifications required to perform the functions needed by your boiler and that the well is of the proper size.

    Honeywell Aquastat Wells

  • 8/19/08 Heat exchanger maintenance

    • Hydronic heat exchangers should be taken apart and cleaned approximately once a year or once every other year for optimal performance. To clean your plate heat exchanger, take apart the pieces and soak it in lime (the acid). The lime will un-clog any potential issues and make sure that your heat exchanger will work properly again. Hydronic Heat Exchangers (FP-Series 5" x 12" Models)
  • 8/18/08 Replacing a Taco ESP Zone Valve

    • Taco ESP Zone Valves (or Energy Storage Principal Zone Valves) are just an older model of current EBV Zone Valves (Electronic Ball Valve). The EBV's are a direct replacement of the ESP, only the name has changed, so if you're looking to replace your ESP Zone Valve, just make sure that the sizing matches up for your new EBV Zone Valve. Taco EBV Zone Valves
  • 8/15/08 Solar Panel Installation

    • When it comes to flat panels, for every 10 square feet of home, you need approximately 2 square feet of panel. This should only be used as a guideline, as other factors involved in determining the number of panels include the area you live in and how much sun your home is able to soak up.

    When installing solar panels, always face your panels towards the equator. For the USA and Canada, that means face them toward the south in order to obtain maximum efficiency.

    Flat Plate Solar Panels

  • 8/4/08 Taco Flo-Chek Operation

    • Taco Flo-Cheks open automatically when the circulator starts running. When the room thermostat is satisfied and the circulator is stopped, the Flo-Cheks close immediately, preventing gravity circulation. Gravity circulation of water is induced by the difference in specific weight or density of the hot water in the vertical supply pipe and the cold water in the vertical return pipe. The lighter hot supply side water, which naturally wants to rise, is drawn up and around the system by the "pulling down" effect of the heavier cold water in the vertical return pipe. The amount of gravity circulation is dependent on the height of the system and the differential between the hot and cold temperatures. In systems with multiple zones, "ghost flow" may occur if a Flo-Chek is not installed on each zone. Ghost flow is induced when a circulator on one zone is running but is still able to bypass water through a zone that is not calling, due to a differential in piping resistance between the two zones.

  • 7/23/08 Exactly how long are your loops?

    • You don't need a tape measure to know how long your loops are. PEX Tubing is marked every 3 feet, so if you look at the markings going from and coming back to your manifold on the same loop, you can just subtract the lower marked number from the higher and know, within a few feet, the length of your loop. Make sure not to use loops longer than 300 feet in radiant heat applications to avoid heat loss. 1/2" 1000 ft hePEX Tubing
  • 7/22/08 Which pumps use Webstone flanges?

    • Webstone Isolator Flanges can be used with circulator pumps of all kinds including all Taco pumps, Grundfos pumps, and Bell & Gossett pumps. Webstone Isolation Flanges
  • 7/21/08 Water Heater Adapters

  • 7/18/08 Firomatic Oil Valves

    • The handle of Firomatic valves is made of a special alloy that melts at a very low temperature. In the event of a fire in the boiler room, the handle of the shaft melts off which frees the plunger and shuts off the oil flow to the burner. Firomatic Oil Products
  • 7/17/08 Sizing your pressure reducing valve

    • A properly sized valve prevents noisy operation and premature valve failure. A valve that is too large can lead to problems such as wire draw under low flow conditions. In general, the minimum flow through a water pressure reducing valve should be 10% to 15% of the maximum flow rate desired in the system. Pressure reducing valves should be selected based on the flow and pressure ranges listed, not by the size of the pipe they will be attached to. You should select a regulator whose operating pressures fall within the middle of its rated range. Pressure Valves
  • 7/16/08 Naming tees

    • Tees are named first by the size of the ends, and then by the size of the middle connection (typically called end-end-middle). The order of the ends does not matter; for example, a 1/2" x 3/4" x 1/2" tee would function the same as a 3/4" x 1/2" x 1/2" tee if you just flip it around. If a tee only has one size listed, all three connections are for the same size pipe. Brass Tees
  • 7/15/08 How far will heat travel from each blue heating wire?

    • Suntouch wires are woven 2.75 inches apart so that people will not feel any cold area between the blue wires at that spacing. However, if your tile extends three inches past the wire, you will probably feel a temperature drop. Your radiant heated floor temperature can also be affected by the presence of ductwork below, insulation variations, solar gain, and heat loss outside. All of these are good reasons to plan your layout so you can install the heated floor mats where they will do the most good. 240 Volt Suntouch Radiant Heat Mats
  • 7/14/08 Plumb like a pro

  • 7/10/08 Tools for your manifold

    • Different manifolds require different tools. If you are using a HydroPEX Crimp Copper Manifold, you have two choices for your tool- either the HydroPEX Clamping Tool or the Watts Crimping Tool. Both of these tools are used with HydrdoPEX fittings but require different rings to make the connections (stainless steel for Clamping and copper for Crimping). HydroPEX Crimp Copper Manifolds
  • 7/9/08 An uphill tank

    • If your septic tank is located uphill from your house, a sewage pump will be required to get the waste to the sewer line. Make sure that you get a pump large enough for the waste to travel the full distance and install check valves to ensure that sewage water does not re-enter the sump and building. Little Giant Sewage Pumps
  • 7/8/08 What voltage does my thermostat use?

    • Thermostats run on either line voltage or low voltage. The easiest way to tell if you need a line or low voltage thermostat is to look at the wire. If it is a very thin wire (like a doorbell or speaker wire), you will need a low voltage thermostat. If it is a heavy wire, you will need a line voltage thermostat. Honeywell TL8230A1003 Line Voltage Thermostats
  • 7/7/08 Matching your flanges

    • If you need a pump for potable (drinking) water, you must use a bronze pump. With a bronze pump, you absolutely need bronze flanges. Cast iron flanges will rust, compromising your whole system. With a cast iron pump, you can use either bronze flanges or cast iron flanges. With no clear benefit of using bronze flanges with a cast iron pump, most people opt to save some money and use cast iron flanges. Bronze Taco Flanges
  • 7/3/08 Facts about Indoor Air

  • According to the Environmental Protection Agency, the air in homes can be up to 100 times more polluted than outdoor air.
  • The National Academy of Sciences Institute of Medicine reports that exposure to indoor pollutants is a key contributor to the asthma problems of this nation.
  • Most allergy and asthma sources are passed from person to person through the air.
  • The air in a single room can contain hundreds of thousands of infectious bacteria, viruses, fungal spores, and contaminants, which can only be seen with a microscope.
  • Health effects may show up immediately, or after years of exposure to poor indoor air quality. These symptoms include some respiratory diseases, heart disease, and cancer. They may be severely debilitating or fatal.


    • Clean your indoor air with UV light using a product that is friendly for the environment and your wallet. UV-Aire Air Purification Systems
  • 7/2/08 Thermostat placement

    • Where you put your thermostat can greatly change how effective it is. If your thermostat is directly under an air conditioner or next to a window, this cool air will make your thermostat think that the room is colder than it really is. If the thermostat is over a lamp, television or heat source, it will read warmer than the room is. Put your thermostat away from these items and you'll get accurate readings to send the right commands to your heating and cooling systems. Series 300 Robertshaw Programmable Thermostats
  • 7/1/08 Save water with an efficient toilet

    • An efficient toilet or flushometer can really save money on your water bill. Some flushometers use less than 2 gallons of water per flush while others flush almost 5 gallons! To check if your toilet is silently wasting water, place a few drops of food coloring in the tank. If the colored water makes it to the bowl without flushing, you are losing water.

  • 6/27/08 How did polyethylene get its start?

    • Polyethylene was invented in the early 1930s and played an important role for the Allied Forces in World War II. British scientists took polyethylene and used it as an insulator allowing British pilots to have radar on their planes for the first time in history. Airborne radar was a great technical advantage for battles fought through clouds with low visibility and for long-distance warfare. Polyethylene has come a long way, as it is now cross-linked and used for plumbing and heating water lines all throughout Europe and North America. ThermaPEX 1/2" x 300' Tubing

  • 5/28/08 Installation position of heating pumps

    • Never install a pump with the can pointing up. Most Taco and Grudfos pumps are water lubricated and most pressures in residential heating systems will never overcome the 20 psi constant to lubricate the cartridge. This can make the pump seize forcing you to replace the cartridge earlier than under normal operation. Cast Iron Taco Pumps
  • 5/27/08 Make your boiler more energy efficient

    • Hook up a boiler reset control such as the Taco PC700. Your boiler is designed for worst-case scenario heat loss, but a PC700 will modulate the boiler to true outdoor conditions. This quick fix can save you between 18% - 35% on your fuel bill. Taco Boiler Reset Controls
  • 5/23/08 When to pressure test your radiant heat system

    • After you've laid out your PEX tubing for a radiant heat system, make sure to pressure test BEFORE you pour your slab to make sure that nothing has punctured or disconnected. You should pressure again DURING the slab pour and then once more AFTER the pour, just to make sure that everything is working properly before you need to rely on that system for heat. The more you pressure test, the more sure you'll be that your radiant heat will keep your home comfortable all winter long. TruFlow Pressure Test Kits

  • 5/20/08 Why use a full port zone valve?

    • A full port zone valve is true to it's pipe size. A 3/4" zone valve full port is true 3/4" throughout the bore, therefore the CV value the valve can handle is higher than a valve that is not full port. In other words, the pressure drop through a full port valve is a lot less than with a valve that is not full port. 3/4" Taco 570 Series Zone Valves
  • 5/19/08 Don't push through that valve, pull through it.

    • Always put your pump after your mixing valve. Never push water through a mixing valve- this can damage the valve. Putting the mixing valve first will allow it to function properly for years to come. Taco Mixing Valves
  • 5/16/08 How to bleed a radiant manifold

    • Radiant heat manifolds should be bled one loop at a time. While you might think that bleeding everything at once will make the job go faster, this will actually add several hours! The fastest, most efficient way to bleed a system is one loop at a time. Radiant Heat Brass Manifold Packages
  • 5/15/08 How a thermostatic radiator valve works

    • There is a dial built into the thermostatic radiator valve. The more that you turn the dial closing the valve, the less heat is emitted. This valve works as a thermostat and a valve built into one. Thermostatic Radiator Valves

  • 2/29/08 Placing a barrier between your galvanized and copper pipes

    • Many old homes have galvanized pipes, and many more have corroded galvanized pipe that has been replaced with copper. It is important to make sure that the copper and galvanized pipe never directly touch each other--when these dissimilar metals come in contact, electrolysis results, which speeds up the deterioration of the pipe. Putting a dielectric union between these metals will solve your problem and make for a safe connection. Galvanized Fittings

  • 1/16/08 How to unclog a toilet

    • A toilet auger is a special tool that has an offset hand crank, a long sleeve handle and a special auger bit at the end to break through a clog or retrieve an obstruction like a rag. The auger bit is connected via a flexible shaft to a crank handle that you control. It's reach is about 3 feet. Here's how you use this tool.

    * Some toilet bowls drain to the front, some to the rear. Whichever way yours drains is the direction you want the curved end of the auger handle pipe to face.
    * Leave about 4" to 6" of cable between the drain hole and the end of the curved handle pipe, then tighten the set screw.
    * Push the flexible cable into the drain and crank the auger clockwise until it stops then push forward.
    * The auger may feel like it grabbed something or it may just break up the clog. If it feels like it grabbed something, pull it out to check. If it gets stuck, gently turn the crank back and forth or push and pull the tube, but never force the auger or you may break the toilet porcelain.
    * After breaking up the clog use the plunger again to make sure the obstruction is cleared.
    * Once your sure it's OK, flush the toilet and you're done!

  • 12/19/07 What is thermal expansion?

    • With modern plumbing codes mandating backflow prevention, thermal expansion can cause pressure buildup in domestic water systems. When demand is put upon a potable water system, hot water is drawn from the water heater. Cold water from the supply line enters the water heater to replenish it. The cold water is heated to replace the hot water used. With the installation of a backflow preventer, check valve or pressure reducing valve on the supply line, the water heater and the system piping from a closed plumbing system under pressure. As the water is heated, thermal expansion occurs. Pressure increases until the relief valve opens and the expanded water spills from the water heater. This spillage results in wasted energy and a potential safety hazard.

    A thermal expansion tank provides control of maximum pressures at a level below the relief valve setting and accommodates the increased volume of water created by thermal expansion, returning it to the system when hot water delivery is demanded.

  • 12/13/07 Why do I need a Flow Control, can't I just use a swing check valve?

    • A Bell & Gossett Flo-Control has two jobs. First the Flo-Control valve acts as a check valve, keeping the system flow from short-circuiting into places where it doesn't belong. Second, and just as important, the Flo-Control valve stops hot water from migrating into a zone that's not calling for heat.
    A swing check valve will do the first job (preventing flow from short-circuiting), but it usually can't do the second. The Flo- Control valve has a weighted check. When the water in the boiler is hot, it tries to rise into the system piping. We call this gravity circulation. The Flo-Control valve's weighted check stops gravity circulation before it can create a problem with your customer.

  • 12/5/07 Should I install insulation in my in-slab radiant heat system?

    • Heating and cooling ("space conditioning") account for 50 to 70% of the energy used in the average American home. About 20% goes for heating water. On the other hand, lighting and appliances and everything else account for only 10 to 30% of the energy used in most residences. It makes good sense to turn lights and appliances off when they are not needed, and you'll save even more on your energy costs if your reduce the amount of energy needed for heating and cooling.

    Unless your home was constructed with special attention to energy efficiency, adding insulation will probably reduce your utility bills. Much of the existing housing stock in the United States is not insulated to the best level. Older homes are likely to use more energy than newer homes, leading to very high heating and air-conditioning bills. Even if you own a new home, adding insulation may save enough money in reduced utility bills to pay for itself within a few years, continue to save you money for as long as you own the home, and increase the resale value of your house.
