CONDENSING BOILER INSTALLATION 

REQUIREMENTS

The  Warmflow  condensing  boiler  can  be  fitted  to  most  installations  using 

standard practices and techniques.

There  are  however  a  number  of  considerations  that  must  be  taken  into 

account.

.  All existing systems must be properly flushed to remove any sediment/

sludge in order to prevent any blockage or reduction in efficiency of the 

boiler.

2.  The system must be fully pumped.

3.  The  primary  difference  between  an  ordinary  boiler  and  a  condensing 

boiler  is  the  condensate  drain.  The  drain  can  be  plumbed  from  the 

condensate trap in any ordinary plastic pipe, eg, plastic overflow pipe, 

directly into the household drain or soak away.

 

Any blockage in the drain could lead to an alteration in the combustion 

settings because of partially blocked flueways.

 

Where the boiler is fitted into a basement a condensate pump may be 

required.

4.  As an indicator of the increased efficiency of a condensing boiler there 

may  be  a  visible  plume  of  ‘steam’  from  the  flue.  Care  needs  to  be 

exercised when positioning the appliance and selecting the type of flue 

to ensure that the plume does not cause a nuisance to the householder 

or to surrounding properties.

 

As  the  water  temperature  in  the  system  rises  the  pluming  effect  will 

diminish. Even where pluming is not visible the boiler is still operating 

more efficiently than a standard boiler.
