Plant Room Upgrade
WHAT IS A BOILER MANAGEMENT UNIT?

The boiler management unit is a device designed to control the burner firingPlant-image1
patterns on conventional gas or oil fired boilers of 50Kw or above. It is designed to control the boiler only, and will not conflict with an existing Boiler Management System.  Instead, it provides optimisation, compensation and sequencing systems or legionella control for stored hot water.

Integration with Building Management Systems (BMS)

A BMS will control the boiler output by signals from various sensors
located around the building, as well as incorporating time scheduling,
boiler sequencing, weather compensation (variable temperature control)
or demand control. None of these control strategies create conflict or duplication with the PRU.

MONITORING AND POTENTIAL SAVINGS
How will the savings be monitored and reported back to you?

• Savings will be reported through the Remote Tracking Unit (RTU) which clients can access via a web portal.  The RTUPlant-image2 allows you to review savings within a matter of days and plot performance against expectation. It also ensures that potential problems are flagged and investigated quickly, guiding operations and ensuring maximum benefits.

Where else has it been used and how much has it saved?

• These units have already been installed in over 9,000 locations with average savings in excess of 15%. One of our clients is BUPA Care Homes for which we recentlycarried out a test pilot to further clarify savings.

ABOUT BOILER
MANAGMENT UNIT

Reducing energy consumption without reducing comfort or performance of your boiler

WHAT ARE ITS SAVINGS AND PAYBACK?

We guarantee the unit will deliver 10% savings in gas/oil consumption but we do see the unit typically delivering savings of 15% and it can help extend the lifespan of older gas and oil powered boilers, potentially delaying the replacement of boilers. Payback is usually around 12-24 months dependent on overall gas consumption although it can be as little as 9 months.
HOW IT WORKS

The boiler upgrade unit works with your existing gas or oil powered boiler and control systems to reduce energy consumption without reducing comfort or performance. Your heating/hot water system will not drop in temperature as a result of installing the unit. Typically you will see 50-100 less firings in a 24 hour period increasing efficiency and helping to increase the life of your boilers. The unit is easy to install, typically taking less than 2 hours, and does not interrupt the operation of the system. The unit is also certified by the Building Research establishment (BRE).

How it differs from other providers

Once operational, the unit’s unique intelligent remotePlant-graph1 monitoring software allows you to monitor savings
achieved on a daily basis from your own computer. The savings report can be accessed at any time to give up to date information on current savings levels and cumulative savings achieved.
Not an anti dry-cycle solution. Such units can inhibit the boiler from firing when the building load is satisfied and lead to unsatisfactory performance.

PERFORMANCE

Cenergist carried out test install for BUPA with unit being switched on and then off over 12 day period with meter readings taken to demonstrate savings. The units were installed onto two boilers. The ‘dips’ in the graph below show when the unit was turned on.

PLANT ROOM INSULATION OVERVIEW

 

In addition to the boiler managerment unit,it is always beneficial to insulate the plant room. This eliminates unnecessary heat wastage in boiler rooms by ensuring all un-insulated valves, flanges, cnnections and other awkward shaped fittings are insulated. A recent case study at a school in Eastbourne showed that where 115 assorted plant room insulation covers were fitted in the plant room, a payback of 1.5 years was achieved based on a fuel cost of 2.5p/kWh. All of the products that we offer our clients demonstrate quantifiable energy savings – oth fiscally and also carbon, we always provide clear payback periods. Simple to install Plant Room Insulation keeps heat in the system and delivers valuable savings.
