Fox & Co can install an unvented
hot water system such as the Megaflo which is widely regarded as the brand
leader in unvented domestic water heating. It offers levels of performance
that are quite simply unrivalled by the competition with flow rates of up to
72 litres per minute. Whether it's a single bedsit, a luxury family home or
a busy sports club shower complex, Megaflo ensures a constant supply of high
power hot water; day in and day out, year after year. Contact us now

General Information
Copper cylinders have been used
to store hot water in British homes for more than 90 years.
The advantages of copper as a
material in hot water systems are unrivalled and have been proven many times
over. Its resistance to corrosion and heat transfer capability are
properties which make copper a natural and ideal metal used universally
throughout British plumbing practice. Indeed, there are currently over 20
million copper hot water systems installed in the UK.
An
emerging demand is now being seen for unvented hot water storage cylinders
and the same properties that have made copper synonymous with domestic hot
water in Great Britain apply equally in unvented packages.
The traditional British
domestic hot water supply system, in which water is heated and stored for
use, is based on cold water feed from a storage cistern to a heated cylinder
that is vented to the atmosphere. The flow rate and pressure of the hot
water discharged from the hot water outlets is then dependent on the height
of the storage cistern above the outlets.
The desire to remove cisterns
from the roof space means increasing difficulties in meeting consumer
demands for modern designs of high performance hot water systems and in
particular the growing market for showers, from traditional open vented
systems.
Unvented domestic hot water systems can, however, meet these
expectations by utilising regulated cold water supplied directly from the
mains to the heated storage cylinder. Included with the cylinder is a
package of safety devices and controls to regulate temperature and pressures
within the system. This type of system can provide flow rates in excess of
25 litres/min thus meeting BS6700 specification for design flow rates of 18
litres/min whilst retaining the facility for simultaneous draw-off from
other hot water outlets.
Unvented hot water systems such
as the Megaflo work on a simple principle. The cold-water mains are
connected directly to the supply units, (taps etc.) providing balanced hot
and cold water throughout the home. This prevents the need for a storage
tank in the loft, thus eliminating the associated risk of freezing and
contamination. As a result, fitting time and expenses are reduced.
Keeping the hot water
generated separate from that required for the heating, of the home
results in improved efficiency and economy. This is aided by fitting the
correct size unit close to the required point of delivery, (e.g. placing
the boiler in the kitchen) thus reducing heat loss through long pipe
runs, indeed cutting out the need for long pipes altogether.

This solution results in
fast, safe, economical hot water supplies, enabling power showers
without a pump and delivering balanced hot and cold-water pressures
throughout the home.
