What is the heating system on an Energy Kinetics boiler?
The hot water tanks on Energy Kinetics boilers are typically heated with a high-performance plate heat exchanger that allows the tanks to heat from the top down. When the burner stops heating the boiler, there is a reservoir of unheated water at the bottom of the tank. The Energy Manager dedicates the energy left in the boiler to completing ...
How does a cast iron boiler work?
Heavy cast iron boilers leave heat wasted in the boiler after every thermostat finishing call. In addition, these boilers are constructed with flue passes that are designed for excess air flow. This design causes energy to be swept out of the vent system. This combination causes up to a 40% annual energy loss. Energy Kinetics gas boilers are super insulated and utilize smart control to ensure energy is not wasted at the end of each cycle. This superior design virtually eliminates all heat loss.
Why is my boiler not condensing?
Poor Design – Most mod-con and combi boilers do not condense continuously or reliably during the coldest weather, when they run most frequently. Many designs are so restrictive that boilers have dedicated circulators and ensure flow to prevent the unit from overheating and failing. This process short-circuits flow and makes the boiler run hotter, preventing condensation. Lack of condensate prevents the unit from flushing and cleaning the heat exchanger, allowing combustion byproducts to build up. This build-up causes fouling that will eventually cause the system to prematurely fail. Also, very small boilers and water passes are prone not only to fouling and premature failure, but these systems reduce a boiler’s running efficiency. Additionally, many systems require complicated field-installed piping and extra pumps to protect the boiler from low-flow damage. This recirculated-hot-boiler-water design reduces condensation and increases fuel bills.
How long does it take to heat a cast iron boiler?
Just Haven’t Evolved – Cast iron boilers have not changed much since their inception. In fact, because they are very heavy, it may take 8 to 15 minutes just to heat the boiler itself. This means on every heat or hot water call, a significant amount of heat is left wasted in the boiler, therefore cutting efficiency up to 40% compared to the AFUE rating ( read study ). In addition, atmospheric cast iron gas boilers run very lean mixtures which increase the volume of flue products. This causes energy to exit the unit via the vent system.

All Energy Kinetics boilers are designed with wide-open flues and water passages that improve efficiency and allow for easy service access.
How often does a hot water tank need to be heated?
When a hot water tank finishes heating (typically three to five times per day), the boiler and piping also finish hot, often 160°F to 200°F, wasting energy every day that hot water is used. Combi boilers often don’t have a tank, but suffer from hot runs and wasted energy as well. In light of these figures, electric hot water tanks may seem ...
