VERSOPUMP- Versol Heat Pumps : Advantages and Disadvantages VERSOPUMP Heat pumps  represent systems that ‘pump’ or move heat from one place to another by using a compressor and a circulating structure of liquid or gas refrigerant, through which heat is extracted from outside sources and pumped indoors. Pumping the heat uses less electricity as compared to when electricity is solely used as a means to convert it. During the summers, the cycle can be reversed and the unit acts like an air conditioner. Heat pumps represent the most efficient alternative to fuel, oil and electric systems in regards to both heating and cooling. Gas furnaces do a relative good job, rated close to 98 per cent efficient, however they do not represent a long term solution from a carbon footprint aspect. Heat pumps supply more heating and cooling capacity than the amount of electricity used to run them. Properly designed and installed heat pumps regularly attain more t...

Boiler is a closed vessel that is used to produce steam at desired pressure.There is a reversal chamber for flue gases between 1st & 2nd pass is provided inside the boiler shell, Based on this reversal chamber boilers are differentiated into Wetback and Dry-back. In dryback boiler rear wall is lined with refractory. In dryback boiler reversal chamber has a rear wall that is lined with refractory, which passes combustion gasses from the furnace to multiple tube sheets and resulting in radiation losses.The dry back boiler design uses a common rear tube sheet and features convenient fire-side and water-side access. Dryback boilers also require regular refractory and tube sheet inspection, which can be costly maintenance items. Wetback boiler designs have a water gap between the furnace and back wall, Hence the radiation losses due to refractory lined reversal chamber in the back end smoke box are eliminated as the complete heat of the furnace is transferred to the wat...

What is Corrosion?-  Oxidation is the reason for Corrosion. Oxygen content in the water or air in the system reacts with metal to form oxides which eat up the body resulting in formation of Cavities and holes. A.      Corrosion in Boilers A1. Reasons for Corrosion in Boilers ·        Improper and unscheduled maintenance in the system Timely maintenance is required to prevent the corrosion in Boilers and Hot Water Systems ·        Non treated Feed Water in Boiler System If the feed water is not treated, removed oxygen from the water will accelerate corrosion ·        Oxygen or Carbon Dioxide present in Water ·        Unbalanced pH- Water Shall be maintained Ph value as recommended Periodic maintenance and Water treatment is essential to control corrosion in Boilers B. ...
