Our engineers are fully trained and registered in the installation, commissioning and servicing of unvented hot water cylinders.
All Unvented Cylinders require servicing annually to maintain a safe operation.
These units
The advantages and disadvantages of an unvented hot water cylinder are:
ADVANTAGES
Balanced pressures at both hot and cold taps.
High performance showering throughout the house.
Faster filling baths.
No cold water tanks in the loft space to be contaminated or to freeze in winter.
Quick installation and quite in operation.
Fast heat recovery (typically 23 mins for 170L
Can be fitted anywhere in the thermal envelope of the property.
Minimal heat loss, performance exceeds CHeSS best practice and Part L of building regulations.
Faster flow rates than any combination boiler unit and still keeping the immersion heater backup.
Mains pressure potable water at all outlets, up to 55 litres per minute.
DISADVANTAGES
No storage back up if the mains water fails.
Poor mains water pressure will cause poor performance.
Need for a discharge pipe (overflow).
Requires servicing yearly.
An unvented hot water storage cylinder can be heated directly via an immersion heater or indirectly by
most heating systems providing it is not a solid fuel burning appliance (e.g. it has to be a Controllable heat
source) They are ideal where high performance is required or in multi story properties where it would be
difficult to gain the necessary head of water via a cold water storage tank to feed taps on the upper floors.
We also install thermal hot water stores
Cold water accumulators
These cold water accumulators connected with the unvented hot water cylinders can give performance
unrivalled by any other water heating system. High flow rates to multiple outlets can be guaranteed even
with an incoming mains flow rate as low as 5 litres per minute
!!!!! Unvented cylinders can be installed with an extra heat exchange coil for solar heating systems !!!!!
