BOILERS, PUMPS & VALVES
Can you save energy by using a domestic boiler
in commercial premises? For thousands of businesses operating out of commercial spaces across the UK, a commercial boilermay not be necessary, as Sean Keleher, technical director at Navien UK, explains
T
o ensure such a vast amount of space is adequately heated and all hot water outlets
can be used with ease, commercial properties usually require a much larger, more powerful, boiler. Traditionally, the size or output of a commercial boiler is 70kW or more to provide enough power for greater reach throughout the property, while domestic boilers will typically range from 24kW to 42kW outputs but can, in fact, range anywhere between 50kW and 70kW for larger homes. These tend to have six or fewer occupants living in the premises and more than 12 radiators to heat the house. A key difference between domestic and
commercial boilers is their lifespan, which can differ depending on how much they are used and how often they are serviced and maintained. Domestic boilers usually have an expected lifespan of 10 to 15 years, while commercial boilers can be anywhere between five to 15 years, as these systems will typically work harder to reach a much a higher demand. However, while most commercial properties
require larger systems,many businesses have the same, if not fewer requirements, than a small to medium-sized home. This would include smaller high street stores, corner shops and local cafes, as these types of businesses would typically only use one or two hot water outlets and have a much smaller space for central heating to cover.
CONSIDERING BUSINESS TYPE Business type will have an effect on the system selected. For example, a high street travel agent and a hair salon will operate out of similar spaces
but will require different appliances because of the service they provide. As a travel agent may only have two or three rooms to heat, with a hot water outlet in both the staff kitchen and bathroom, the business would benefit from a combi boiler designed for a medium-sized home – such as the Navien NCB500 ON Combi Crossover which provides up to 41kW of hot water output. However, while a hair salon would also benefit
from this system, it would require an additional hot water heater – like the Navien NPEWater Heater – for customer facing hot water outlets, as they require instant hot water consistently throughout the day to meet the demands of the business. Otherbusinessessuchassmall officesoroffice
blocks would benefit from a domestic boilermade for a larger home, such as the Navien NCB700 ON Combi Crossover, which provides a powerful 54kW hot water output. These larger, more powerful systems, can heat 20 to 30 radiators depending on heating design temperatures, making it a great choice for smaller businesses looking to heat the property but for a lower cost. Both the NCB500 ON and NCB700 ON feature the
same technology from Navien’s NPEWater Heater to provide consistent hot water without seeing a drop in flow rates, all from a single unit. Price points for a commercial boiler typically
start from around £2,000 and can be in the tens of thousands for more powerful units, which are commonly used for much larger properties. For domestic applications, most units are under £1,000 and are between 10% and 20% servicing and maintenance costs.
Navien UK’s boiler range comes in at incomparable
prices to ensure home and business owners can have a superior system with premium quality build and excellent performance.
SAVING ENERGY The NCB ON Combi Crossover range offers hassle-free installation thanks to its highly efficient capabilities in a compact unit. The range has been designed to offer the same power of a high- performance system boiler with the cylinder-less advantages of a compact combi model. This lead Navien to create the Combi Crossover range, an entirely new category for the industry. For business owners, choosing to install a
domestic boiler instead of a commercial boiler could even help them to reduce their energy usage and their bills. The NCB ON Combi Crossover range is 20% hydrogen-ready with an ErP A+ rating when used with Navien’s Smart Plus controller, which offers users a wealth of advanced features. The advanced control can be accessed from a mobile phone, allowing business owners to control the system from wherever they are, which helps to reduce energy bills even further. Featuring innovative AI technology such as
Smart Forecast and Geofencing, Smart Plus is designed to make heating simpler. Smart Forecast will respond intuitively to the current weather conditions to ensure the property remains at a comfortable temperature, while Geofencing allows users to switch the boiler on or off, purely based on their proximity to the premises. This feature is particularly useful for business owners who may have other members of staff arriving at the property before them, as Smart Plus can be used on multiple devices to maximise comfort and convenience.
