Comfort and Health: Hot water and steam heat systems rely on natural convective air currents and radiation of heat. Forced air movement is good for cooling, but poor for heating for drafts have a cooling effect on your body (that is why fans are used on hot days). Ducted air systems also tend to be dirty while the gentle convective air movement in hydronic heating systems does not “stir” the dirt, hydronic heat is cleaner and healthy. Many people have converted their warm air heating system to hydronic heat due to dust allergies.
Efficient: Hydronic heat uses small pipes to transport heat to heated areas. Heat lost through these pipes is minimal. Forced air uses large ducts, large ducts lead to air leaks with large heat losses. Moving hot water throughout a typical house requires a circulator pump that uses a lot less than 100 Watts and it budget figure is around $25.00 of electricity per year. A typical forced air heating system’s blower uses more than 500 Watts and it costs approximately $200.00 of electricity per year to move the warm air throughout the house. A hot water boiler and warm air furnace A.F.U.E. range is generally from 82% to 95%, so that is similar. However it does cost a lot more to distribute heated air throughout a house than it does to circulate hot water throughout the house.
Quite: Hydronic heating systems are generally quieter than a warm air system. With hydronic heat the hot water is gently circulated through small pipes. With warm air is forced through the ducts and discharged into a room with fast enough air flow often creating a “whooshing” noise.
Bottom line is hydronic heating systems are:
- More Comfortable
- More efficient
The one drawback is a forced air system is cheaper to buy.
But do you live in the cheapest house or drive the cheapest car?
Hydronic heating is a great way to save energy and still stay warm, without sacrificing comfort. Hydronic heating works by circulating hot water throughout a location by warming the essential parts of a house like baseboards, radiators, or radiant tubing in floors or ceilings.
HOW IT WORKS
Hydronic heating works by moving heat using the conductor of water to where it is most needed to warm a space. Unlike furnaces, which simply warm the air and disperse warm air throughout the house, hydronic heating uses water instead as its “conveyor belt” that moves the heat via the water to its destinations.
BENEFITS OF HYDRONIC HEATING
• Unsurpassed comfort
• Energy saving
• Design versatility
• Clean operation
• Easy installation
BENEFITS OF HYDRONIC HEATING FOR ENERGY-SAVING
-Hydronic heating uses boilers (either gas boilers or oil boilers) for the medium that it needs to heat up the water that will pass through the various channels. This saves energy by bypassing the need for furnaces or central heating and will also save on your heat bill.
-Since using gas boilers or oil boilers keeps the process localized in a central boiler or chamber, energy is contained within a specific area until the product (heat) is dispersed throughout the house or building via warm water that has been heated up by the boilers.
-This method of heating is also ideal due to the fact that there is less heat loss, which often results in higher energy bills. Because a hydronic heating system does not focus on air exchange where some heat can escape, the warm is dispersed through a contained environment that results in radiant floor heating and this creates a more even heating result throughout the space.
WHY UPGRADE YOUR EQUIPMENT?
Hydronic heating is perhaps one of the best methods to keep heat in during the cold months, and the cold out. It saves energy by keeping the heating system in a contained environment and disperses the heat evenly through a process known as radiant heating. But your system is only as good as your equipment. It is important to keep your boilers upgraded so that your system will operate at peak efficiency. By replacing old equipment, such as gas boilers regularly, you will keep your hydronic system running at top efficiency at all times. Upgrading your boilers and other equipment also keeps your system running clean, which further contributes to protecting your energy source and the environment. By keeping your hydronic heating parts updated and running clean, you will enjoy a better heating system for years to come, save money on energy bills, and know that you are doing your part to preserve the environment.

THE 2015 “SHOW & TELL BOILER INSTALLATION CONTEST”
From Daniel Y. of Lowell Mechanical, Medford, NY
East Hampton 4,500 sq/ft private home (6) zone Climate Master Geo thermal heating and cooling system with Slant/Fin CHS high efficiency L.P. fired boiler for supplemental heat, hot water, pool heat, spa heat and garage heat.
New steam boiler installations introduce chemicals, such as cutting oils, into the steam system. Mud and dirt build up in the system piping for years and often breaks loose during removal of the old boiler and installation of the new boiler. This often leads to foaming (priming) and surging of the boiler water. Surging and priming lead to low water cut-off shutting off the boiler and can also lead to boiler failure. Clean water is required to prevent this. Therefore new steam boiler installations require cleaning, this cleaning may require multiple return visits to the job.
A clean system and clean water are the goals. Even when you clean the boiler water in a new replacement boiler after operation scale, dirt and oils present in the system piping will be flushed back to the boiler.
Boiler and system cleaning
- Draining and flushing of the boiler will remove solid material and dissolved additives, however it does not remove oils, grease or other films that have lined the boiler and system piping.
- Chemical cleaners made specifically for steam boiler systems, such as Utility brand “Dry Stream”, help prevent priming and foaming surging, also loosen rust and mineral deposits and aid in cleaning of the boiler and system. Remember to flush all additives from the boiler and system after a week or two. Dry Steam is a product of Utility Manufacturing located in Westbury, NY. We have found Dry Steam to be an effective boiler cleaner.
- Dry Steam is a great cleaner and there are a couple of methods for “blowing-off” a Slant/Fin steam boiler.
- Galaxy GXH and GXHA boilers without tankless coils have a skimming trough built into the casting. This trough is located just below the normal water level. The double sided trough extends for 6 inches in the boiler casting, this gives 12 effective inches to skim the top layer (where the oils sit) of the water surface. Follow the detailed instructions within the Galaxy steam boiler installations instruction to take advantage of this unique feature.
- Boilers without a skimming trough.
- Turn off electrical power supply to boiler. Allow boiler to cool down and also allow pressure to reduce to zero before attempting removal of components. Check for pressure by testing pop safety valve. With no pressure in boiler install skimmer valve and skimming piping as shown in Figure B. Make sure the bucket used to catch skimming discharge if covered with a cloth to help prevent hot skimming discharge escaping the bucket and leading to a dangerous situation.
- Cautiously open the skimming valve, do not open the boiler drain valve. Slowly fill the boiler with water until water seeps into the bucket. Maintain this water level so you are just able to continue skimming. Fire the boiler and allow water the slowly skim and seep into the bucket. Empty the bucket frequently and continue skimming until water is clean and no oil can be seen floating on top of the water in the bucket. This process may have to be repeated until the system and system water are clean. On dirty systems this process may have to be repeated after a few days or weeks.
- When finished remove the skimming piping, remove tee below pop safety valve and install pop safety valve following the boiler’s installation manual.
- Never install a valve between the boiler and the pop safety valve. Install discharge piping on the pop safety valve following the boiler’s installation manual and local codes. Make sure all pipe connected to the pop safety valve is sized the same as the pipe connections to the valve. Never decrease the pipe size connected to the inlet and discharge sides of the pop safety. Never have a valve installed in the piping to or discharge side of the pop safety valve.
- Never add any type of chemical or cleaner to a steam boiler or steam system unless it is a product made specifically for steam systems. In a low pressure steam boiler water liquid expands around 1700 times when the water becomes low pressure steam. A lot of action goes on within a steam boiler so the boiler and system must be clean to produce quality dry steam into a steam heating system. Further, to ensure proper water level stability during steam boiler operation it is imperative the “near boiler piping” is installed exactly as detailed in our boilers’ installation instructions. During operation the pressure at the supply and return openings to the steam boiler must be equal, this is why you install the “equalizer” piping. Improper piping and cleaning of a steam boiler also leads to noisy banging (water hammer) in the system pipes. Steam velocity is fast and can exceed 40 miles per hour, this is one reason why “dry steam” is the only steam that should leave a steam boiler.
- We suggest you adjust the cut-out for the PA404A1009 Pressuretrol to a maximum of 2 P.S.I.G. with a 0.5 P.S.I.G. cut-in for normal residential boiler operation.

THE 2015 “SHOW & TELL BOILER INSTALLATION CONTEST”
From Bill S. of Verne & Ellsworth Hann, Inc. Cleveland Heights, OH
“The homeowner had become increasingly concerned with the original coal boiler from her house. The house was built in the early 1920’s. It was converted to natural gas at some point. During the extremely cold winter months, the homeowner decided it was time to invest in peace of mind and higher efficiency. Old boiler hauled out, new Slant/Fin Galaxy Steam boiler in its place… the heat was back on in one day.”
A Hybrid Boiler System is a combination of two types of boilers used in the same system. Slant/Fin Hybrid Boiler Systems combine high efficiency condensing boilers with non condensing cast iron boilers.
How do you decide the make up of a Hybrid Boiler System?
On most existing hot water heating systems generally two thirds of the boiler system capacity will be in the non-condensing water temperature range and one third of the capacity is in the condensing water temperature range. Condensing water temperature is 130F or lower and above 130F water temperature we are above the condensing water temperature. Your mechanical engineer can calculate what percentage of your heating load can be satisfied in the condensing water temperature range and therefore, choose the condensing boiler capacity for your heating plant.
