Commercial & Domestic
Commercial & Domestic Heating & Gas Services: Boiler Systems
Choosing one of the different types of boilers for your facility can be confusing. It’s important to understand each of the different types of systems as well as their pros and cons. Fortunately, you don’t have to go at it alone.
The experts at Enertech FM ltd offer years of experience helping Retail, Commercial, Education, Industrial, Corporate and, and Public Authority properties.
Our engineers and contracts managers will guide you through the process to ensure you make the most intelligible decision. In the meantime, use the following information to for an overview of the different types of boilers.
Commercial boilers are designed with a firetube, small water tube, and electric resistance. They work ideally for universities, libraries, office buildings, schools, laundries, hospitals, and other similar facilities. Among the different types of boilers, commercial boilers are some of the most diverse. These units can use propane, natural gas, non-fuelled electric only, or light oil to provide hot water or steam for process requirements or comfort heating. Based on the commercial boiler selected and application, these systems boast a fuel efficiency as high as 99%.
Commercial Heating Systems
Enertech FM ltd has years of experience with most major types of boilers within all types of commercial buildings, including:
- Boilers and multi-boilers (gas, oil, LPG, wood, etc…)
- Heating controls and sensors
- Valve and pump (including shunt pumps)
- Forced-draft and warm air conditioning systems
Hot water systems
We know that reliability and running costs are the most important factors in commercial heating systems. That’s why our experienced design team will find the right system for your organisation and offer the best solutions for your complete air comfort.
Types of Commercial Heating
Forced-draft or “Warm Air Heating” Commercial Heating Systems
This type of commercial heating is usually the most cost-effective means of heating large commercial spaces. Air is heated via a boiler or heat exchanger and circulated throughout the building through specially designed vents. This method is far more cost-effective for the larger organisation than traditional radiators and boilers.
- Heat is circulated instantly and is therefore easier to control.
- Warm-air heating produces a drier heat that removes moisture in the air
- Particularly well suited for organisations with large amounts of computer equipment.
Wet Heating Commercial Heating Systems
Some commercial building may not suite warm air heating, particularly if they have one large open space with high ceilings and little insulation. In such cases, wet heating systems may be more cost effective and economical to run.
Wet heating systems operate in a similar manner to most domestic heating systems. Water is heated via a boiler and pumped through a sealed radiator system to heat rooms.
Large Open Space Heating
Very large buildings such as factories, exhibition halls, leisure centres, museums and galleries and other open plan buildings require carefully designed heating installations. and these can include Powermatic space heating equipment for which we are now approved service and installation agents for UK South.
Under Floor Heating
With huge advances in heat pump technology, underfloor heating is becoming a much more popular way to heat newly built commercial buildings. It is cheaper to install underfloor heating than traditional wet heating systems. This efficient heating system involves feeding heated water through under floor pipes to distribute heat evenly into each room.
Types of commercial boilers
Fire Tube Commercial Boilers:
A fire-tube boiler is composed of a housing containing the entire boiler’s apparatus. Within this housing are a series of pipes threaded through a holding tank. Beneath the pipes and holding tank is the burner apparatus, which is powered by natural gas, oil or wood chips. When the burner is lit, air is heated. The heated air passes through the closed system of pipes again and again, passing its heat to the surrounding water. As the water boils, the steam passes through a separate network of pipes to heat the house, passing under floorboards and into radiators where the heat is given off. The steam condenses upon cooling and returns to the boiler, where it’s heated again. This type of boiler is very energy efficient in its working, but since it is a closed system, the pressure under which the system works must be monitored closely. As more steam is created, it causes the pressure within the pipes to build. If the pressure goes to high, the pipes can rupture.
Water-tube Commercial Boilers
The water-tube boiler is a reversal of the fire-tube concept, though it’s not found so commonly. Essentially, the shell contains a series of pipes through which water flows in a closed circuit. Around these pipes is a chamber where the heated air stays, continuously replenished by the burners. The pipes heat up and the water they contain slowly turns to steam. The steam rises up to the top of the pipes (they’re vertically aligned), where it passes through the same network of under floor heating pipes and radiators that a fire-tube boiler has. Though the pressure in these boilers is not as great, the continuously flowing water tubes are capable of creating a greater volume of steam than their fire-tube counterparts, meaning they’re ideal for large buildings and commercial structures.
Essentially, condensing boilers are water heaters fuelled by oil or gas. These units can achieve an exceptionally high level of thermal efficiency up to 98%. This high level of efficiency is achieved through the condensing of water vapor in the exhaust gases. With the condensing design, the boiler recovers a portion of the latent heat of vaporization, which would otherwise be wasted. Most models boast efficiencies over 90% when the temperature of the return water is at or below 110 ºF. As the temperature of the return water decreases, your efficiency gain will increase.
Most notably, electric boilers are known for being quiet, clean, compact, and easy to install. Without combustion considerations, these types of boilers have no exhaust stack, no fuel handling equipment, and no fuels, which means they have minimal complexity.
Among the different types of boilers, electric units are ideally the perfect solution for overcoming stringent low NOx and emissions regulations. Clients choose electric boilers in areas where the cost of electricity is favourable. These boilers range anywhere from 9kW up to 3,375 kW output.
