COLD WATER SUPPLY
Telford Stainless unvented cylinders are capable
of delivering up to 55 litres of hot water per
minute given an adequate supply. The minimum
recommended supply is 20 litres per minute at
1.5 bar.
WHAT BOILER SHOULD I USE?
To ensure peak performance and efficiency
the cylinder should ideally be connected to an
oil-fired or gas condensing boiler. The primary
circuit must be pumped and can be open vented
or sealed. Energy requirement (BTU/KWH) will
vary according to cylinder volume.
LOCATION
Our stainless cylinders can be sited virtually
anywhere in the home, but consideration must
be given to service clearances and the weight of
the cylinder when filled.
