A designated "mechanical room" is typically used to house the boiler (water heater), pump(s), manifold, valves, and controllers that form the complete hydronic snow melting system. Homeowners need to be aware of this as they consider their radiant heating options. And although the installation costs of a hydronic snow melting system can be considerably more than that of an electric radiant heat system, the operating costs can be lower. A hydronic radiant heat system's boiler / water heater can be found that uses the most economical souce for your area. Boilers can use propane, natural gas, oil, electricity, etc. For this reason large hydronic radiant heat systems may operate at a slightly lower cost than large electric snow melting systems.

Whether you are looking to install a large driveway heating system or simply needing to install a minimal radiant heat system to melt snow in troublesome areas (such as a steep incline) so you can get in and out of your driveway on stormy winter days, Warmzone has the flexibility to meet all of your radiant heating demands.

Legionella is the bacteria responsible for Legionnaire’s Disease, an acute bacterial infection of the lower respiratory tract. This bacterium was first identified in 1977 by the Centers for Disease Control as the cause of an outbreak of pneumonia that caused 34 deaths at a 1976 American Legion Convention in Philadelphia.

Pontiac Fever is a less severe, non-pneumonia, flu-like disease that is associated with and likely caused by Legionella bacteria. Legionella is a fairly common water bacteria and has been found to exist widely in many surface water sources such as; lakes, rivers, streams and ponds. It can also be found in ground water sources and some soils. At the levels found in these naturally occurring sources it typically does not pose a threat to public health.

Hydronic radiant heat systems can often be installed to use the existing boiler or water heater. The liquid used for hydronic radiant heating systems consists of a special mixture of water and propylene glycol (anti-freeze). After being heated, the specialized liquid is then pumped through a network of specially manufacturered PEX tubing installed beneath the surface. (The tubing for hydronic snow melting systems can be installed in just about any medium, including concrete, asphalt, and brick or stone pavers, etc.) Ranging in diameter from ½ to ¾-inch, the flexible tubing can be curved to accommodate the various layout patterns needed. This unique tubing is designed to resist chemicals and corrosion without becoming soft at high operating temperatures or brittle at low outdoor temperatures. (NOTE: In many cases you can use the same water heater for your radiant heating system that you use for producing your domestic hot water.

There are many methods of controlling colonization of Legionella bacteria. However, a widely accepted and preferred method is to maintain the hot water system storage temperature continually at or above 60°C. Unfortunately, the elevated temperature necessary to minimize the growth of and kill Legionella bacteria has the potential to cause serious scalding injuries.

Active Plumbing can offer the services of installation and periodical testing and certification of Thermostatic Mixing Valves Just call us on 1300651965

Installation Testing and Certification of Thermostatic Mixing Valves. Thermostatic mixer valves are used in a wide variety of applications. Restaurants, Nursing Homes, Preschools, and Commercial applications.

For more details about hydronic heated driveways and snow melting systems, call a radiant heat expert today at 888-488-9276.

Thermostatic Mixing Valves maintain and limit mixed hot water to a desired, selectable temperature, helping to minimize SCALDING. More than 90% of scalding incidents occur in the home. The tender skin of very young children and the slow reaction time of the elderly and the handicapped make them most vulnerable to serious hot water burns. Scalding injuries are tremendously painful, and the effects can last for years. Scalding occurs for a variety of reasons. In some cases, water heater thermostats can be faulty, or set too high. In others instances, temperature regulating valves at the domestic hot water source are either malfunctioning or missing altogether. Water heaters are normally set to temperatures above 55°C to prevent development of harmful bacteria, such as Legionella, in the water supply. Water at temperatures above 41°C is painful. At a temperature of 55°C a child can be scalded in less than 4 seconds. Thermostatic Mixing Valves maintain and limit the mixed hot water to a desirable selectable temperature, helping to prevent scalding injury.

TMV’s are required to be commissioned by a technically competent and qualified person. 2. Is there a maximum height that TMV’s may be installed from floor level?

Thermostatic Mixing Valves maintain and limit the mixed hot water to a desirable, selectable temperature allowing for the storage of domestic hot water at the higher temperatures necessary to reduce the risk of Legionella growth in the system.

Every year, thousands of people suffer serious thermal shock or scalding injuries in their bathtubs, basins and showers. Additional untold numbers become ill due to water-borne bacteria, such as Legionella.

Often, injuries in the shower are caused by slips and falls in reaction to a sudden increase or decrease in water temperature. Ideally, if the supply of cold or hot water is lost, the water flow should be shut down immediately. Termination of flow would eliminate the instinctive but dangerous reaction to move quickly away from a too hot or too cold water stream.

Warmzone snow melting systems can be designed to heat specific shapes and areas. You can install radiant heat to warm entire driveways or just heat two 24-inch wide tire tracks. Some customers choose to heat an 8-foot strip in the middle driveway, or a 2-foot wide path in the center of a sidewalk.

Under these conditions Legionella can rapidly colonize, forming higher concentrations that can pose the public health threat of Legionnaire’s Disease.

When the bacterium enters a domestic water system it can find an ideal host environment of warm water temperatures 40-46°C, stagnant water areas (storage tanks and dead-end piping legs) and ample food sources (sediment, scale, deposits and biofilm).

TMV’s are to be watermarked against AS4032.1. This Australian Standard then refers to AS4032.3 Requirements for field testing, maintenance or replacement of TMV’s. This standard states that:

The Warmzone® hydronic snow melting systems utilize a series of pumps and specially treated PEX tubing to circulate specialized liquid to heat concrete, asphalt, paver driveways, or other radiant heat applications. The boiler or water heater heats the liquid which is then pumped through the closed loop of tubing to warm the surface area. Hydronic radiant heating systems can be customized to heat almost any size and shape of driveway, ramp, or walkway, etc. Hydronic heated driveways and snow melting systems can also not only be customized to meet your specific snowmelt needs, but can be tailored to better accommodate your budget.

A record of test results and repairs shall be provided in accordance with AS4032.3 Appendix B. A management system shall be established to ensure the devices are tested and maintained in accordance with relevant regulatory requirements, AS4032.3 and the manufacturer’s instructions.
