Combi Boiler Features

People who live in small homes and apartments will invest in a combi boiler. These are more efficient to use in these buildings because they are small in size and do not require the need to work as hard to heat the home and water. If you are thinking about purchasing a unit than you should look at the various features that it has to offer.

It is important to remember that there are several different types of these units. We feel that in order to get an idea of what each of them is like you need to know the features that each of them has. This will help you to know what will work best in your home.

Gas Combi Boiler

The gas combi boilers are built with high quality combustion systems that are easy to use and to maintain. Most are kept on the top so that they are each to replace if they should break. This will save you from having to spend thousands of dollars to replace the whole unit. The design used on the casing is made to reduce the cost of anything lost and makes the combustion noises down to a minimum. The electric ignition – which is offered on most models – makes lighting it easy and negates the need of a pilot light.

  • Used for radiant and hydronic heating systems
  • Advanced ignition system
  • High quality heat exchanger
  • Functions quietly
  • Compact
  • Electric ignition and no pilot light (on most models)
  • Modulating gas valve
  • Sealed combustion chamber
  • Is wired to be used with indirect water heater
  • Reset built indoor and outdoor
  • 94% efficiency

Condensing Boiler

A number of the modern condensing units offer a combination domestic hot water of 180 galloons every hour. This allows it to modulate the firing rate to 25% of the rated 110,000 BTU every hour. With this modulation it has less cycles and reduces the cost to operate it. This makes it better to use in smaller areas and without a short cycling. A select models are self cleaning and self descaling.

  • Standard mixing valve
  • Stainless steel heat exchanger
  • Temperature sensor built on the outside
  • Stainless steel burner
  • Negative pressure gas valve
  • Three speed Flanged Grundfos system circulator
  • Drain valve
  • Pressure gauge
  • Condense drain
  • 30 psi relief valve
  • NTC temperature sensors
  • Self cleaning and descaling
  • 95% efficiency
