Hot Water Cylinders There are basically two types of hot water cylinder, gravity and pressurised (unvented). Within this they can be heated direct or indirect. There are advantages and disadvantages to both types, in some cases the type of property will dictate the type of cylinder you will have due to location or space issues. Factors in deciding this will include incoming mains pressure, and flow rates, access to loft space, is there even is a loft space? Ease of installing safety blow off pipe as laid down in the G3 Building Regulations
Open Vented (Gravity) This type of cylinder is gravity fed via a storage tank of water which must be above the cylinder. The higher the tank, the greater the pressure, 1 Metre head equals 0.1bar (some shower will fail to operate on such low pressure). You can calculate the working head (pressure) by measure the height from the outlet (e.g. shower head) to the base of the storage tank in attic. In order to vent the cylinder when filling and to accommodate the expansion of the water when heated, an open vent to atmosphere terminating above the cold storage tank is installed. The cold storage tank is usually sited in the roof space. Obviously this roof space is not always available e.g. in a flat.
Unvented Unvented hot water cylinders store water supplied directly from the mains water supply, and heat it using either electrical heating elements or with heat from a boiler. This provides high pressure hot water supplies capable of feeding outlets with high flow rates of hot water. The cylinders store water under relatively high pressures 2 bar upwards, this is depended on the mains cold water supply. The increased pressures also make for more powerful showers, without the need for mechanical pumps. As hot and cold water supplies are fed from the mains there is no more need for a cold water storage tank, keeping loft spaces clear, and pipework to a minimum, and less chance of frost damage, also reduce heat loss normally associated with the pipework in attic.
The Advantages of Unvented Cylinders:
High pressure system. No pump required, means no noise or another item to break. No need for cold storage tank in attic. If stainless steel, has long life span. The Disadvantages of Unvented Cylinders:
Relies on mains pressure. Higher installation costs. Contact Us We install all types of hot water cylinders throughout the South Lakes and Cumbria area. If you want to purchase a hot water cylinder, contact the MCC Heating Services Ltd team today on 01539 263424 or 07968024114 today.
