Worcester Greenstar 18Ri ErP 18kW Heat Only Boiler + Horizontal Flue

 

 

Overview

 

Inclusive of all labour and Parts 

 

The Worcester Greenstar 18Ri is a 18kW heat only boiler ideal for small to medium sized properties with one bathroom. The Greenstar 18Ri is efficient and reliable, helping to reduce energy bills while providing enhanced heating performance. This 18kW boiler is lightweight and compact, small enough to be installed within a standard kitchen cabinet or other areas where space is limited. Installation is fast and easy, a steel wall-mounting plate comes as standard, allowing sufficient space for the included flow and return pipes to fit cleanly behind the boiler. The Greenstar 18Ri 18kW features a highly efficient and reliable heat exchanger and simple user friendly controls, while low NOx and CO2 emissions make the 18Ri much more environmentally friendly.

Condensate pipe

The condensate pipe will be connected into a soak-away or into the existing rain water/ fowl sewer drainage system

 

Room Stat

To meet the current building regulations, we will include in our estimate for installing the following modern controls

 

• Wireless room thermoset

 

A new balanced horizontal flue will be fitted from the boiler through the wall/roof and terminated externally.

 

Electrical works

Allowance has been made for wiring the controls on the boiler and to the controls mentioned above.

 

The mains supply to the boiler and controls will be taken from an adjacent point with all wiring hidden where possible, otherwise run on the surface of adjacent walls

 

No allowance has a been made for service cross bonding which may be required in the house. If this is not present our electrician will advise you.

 

Gas Service

The gas service will be taken from the existing 22mm supply and connected to the control valve on the boiler.

 

System Clean

To meet the current building regulations and conditions of the boilers warranty the heating system needs to be flushed out in accordance to BS7593.

 

This is because the heat exchangers in the new boiler are a lot smaller and can be prone to damage from sediment from radiators.

 

To ensure we remove as much sediment from the sytem as possible we ude a power flushing machine with the aid of Frenox cleaner.

 

This is a long process as each radiator is separately power flushed until the water running through the cleaner is clean.

 

To improve the process, we also agitate the sediment by quickly altering the direction of water flowing through the system and use a rubber mallets or mechanical agitator or magnetic roller on the radiators.

On completion of the works the use of the controls will be demonstrated and a handover pack will be issued with all relevant documentation require to sustained a health system

 

Testing and Commissioning

On completion of the works the use of the controls will be demonstrated and a handover pack will be issued with all relevant documentation require to sustained a health system

 

Handover

On completion of the works the use of the controls will be demonstrated and a handover pack will be issued with all relevant documentation require to sustained a health system

 

Protection

Throughout the duration of the works we will install full carpet/flooring protection to all works areas and access routes with the addition on dust sheets where appropriate.

 

All works areas will be left clean and tidy upon each day’s work and we will endeavour to keep dust levels to a minimum throughout
