NOTES

1.  The diagrams shown are generic. For 

exact product specification refer to 

the table eg. the number of immersion 

heaters varies depending on model.

2.  The specifications shown are the 

standard range, but these can be 

changed at the time of order to suit 

specific installation requirements.

3.  All connections are within 145

˚

, but if 

more detail is required, please contact 

our technical desk on 01253 474584 or 

your local Gledhill depot.

4.  The domestic hot water volume and 

maximum hot water flow rate figures 

are based on the store temperature 

being 75

˚C.

5. 

Heat pump models use a 30 plate PHE.
