There are 5 main types of hot water cylinder available. Each with different operating methods and for different purposes.

Unvented:
Unvented Cylinders work off the mains pressure water, and therefore use the water mains pressurised system to move the domestic hot water around the property, and so eliminates the need for a header tank in the loft.

Unvented Cylinders offer higher hot water flow rates, and are therefore able to provide higher water pressure for showers, baths etc.  As an Unvented Cylinder does not require a feeder tank, this frees up valuable space in the loft area, and also gives you the option to site the Cylinder anywhere you want thus freeing up further space in your airing cupboard.

Unvented Cylinders are generally manufactured out of top quality stainless steel, this ensures long life and durability, and Unvented Cylinders can also carry a manufacturer’s guarantee of up to 25 years. E.g. the Gledhill cylinders range.  Other Manufacturer’s guarantees may vary.

Vented Cylinders:
A Vented Cylinder (or cistern fed) has a header tank that is usually situated within the loft area.  This header tank feeds through the cold water from the mains feed, and relies on gravity to pass the water through the pipes to your heating/hot water system.  A vented hot water cylinder is normally associated with a conventional heating system.

Vented Cylinders are manufactured out of copper, with the copper varying in thickness measured in grades.  The better the grade, the better the resistance to copper corrosion, and therefore advances the longevity of the cylinder.  A domestic vented copper cylinder is usually Grade 3 such as Gledhill hot water cylinders.

Direct:
A Direct Cylinder is heated via an internal element, usually an immersion heater.  The water in the cylinder is heated by these immersion heaters directly, hence why the cylinder is called “direct”.  The water in the cylinder is not heated via any other heat source.  Once the water has been heated, it is then fed out the top of the cylinder and supplied to the required outlet.  E.g. Bath or Tap.  Larger capacity Direct Cylinders can have up to three internal immersion heaters, to ensure the maximum amount of hot water is available.  Direct Cylinders are available in Vented or Unvented Models.

Indirect:
Indirect Cylinders are heated via an external heat source, such as a boiler or solar panel.  The water inside the cylinder is then heated using an internal coil/heat exchanger, which transfers the heat obtained via the external heat source, to the water inside the cylinder.  Although the cylinder is heated via an internal heat exchanger, the original heat is obtained externally, and therefore why it is commonly referred to as “indirect”.  Indirect cylinders may be fitted with immersion heaters, acting as a supplementary heat source, but they will still be considered to be Indirect Cylinders. Some manufacturers supply an immersion heater as standard, therefore any additional ones will need to be purchased separately.  Indirect Cylinders have a faster heat up and recovery time than that of a Direct model. Indirect Cylinders are available in Vented or Unvented Models.

Solar Cylinders:
Solar Cylinders are specially designed for Solar Heating installations.  A mixture of water and a special Glycol liquid (specially designed to absorb maximum heat from the sun’s rays) is circulated through pipe work in the solar panels.  This liquid is then returned to the cylinder where the heat is transferred to the stored water via an internal coil/heat exchanger, the liquid is then pumped back to the solar panels to be reheated.

An additional coil is also required to obtain heat from an alternative source, if the heat from the Solar Energy is insufficient.  This is most commonly referred to as Indirect “Twin Coil” Cylinder.  Direct Cylinders can be used for Solar Power, with the added heat source being supplied via the internal immersion heaters.  It is advised however, to install an Indirect Cylinder, as this provides faster heat up and recovery time.

In these tough economic times, maintenance and refurbishment makes far more sense than replacement.

Most improvements or refurbishments on houses and gardens end up costing far more than was originally expected. By trying to do as much of the work yourself within your capabilities is going to help at times like these. Garage doors for example are items that if working properly are marvellous and add to a property’s aesthetics and value. When not working properly, for example, when they are not opening or closing properly, a car is not safe when inside or imagine the horror if the door won’t open and the car is stuck inside!

An old garage door can look shabby and make the whole property look less desirable especially when it comes to selling a property. A nice, well looked after and in good decorative order garage door is part of the external appeal of a house. With car parking at such a premium these days, having a garage next to the house or integrally can add a lot of value and provide that extra decision making draw for a property.
The cables are components on garage doors that do tend to stop working properly over a period of time. These can be quickly and easily repaired by visiting a garage door spares supplier. Cables can be repaired following careful instructions.

If changing garage door cables yourself, there are some important points to follow:

1. Read carefully any Instructions that are available for your door
2. Always replace both cables/wires at the same time
3. Make sure that you have the correct tools available to enable you to complete the job
4. Make sure that you have the correct garage door parts for the repair.
   (If you are replacing the cables, please also check the roller spindles for wear, as this is a good time to also replace them)
5. Always oil all moving parts.

It is anticipated that air conditioning will be a prerequisite on new build properties in the very near future, due to the running cost saving and the benefit of cooling and heating. There are numerous systems available including the Unico mini ducted system and the more traditional wall and floor mounted options. A very versatile and popular brand is Daikin air conditioning.

Conservatory air conditioning – use it to its full potential!
Having invested in your conservatory, it’s essential you create a room that is perfect for relaxing with friends and family regardless of the season. Temperatures go from unbearably hot in the summer to unpleasantly cold during the winter. Visually, a conservatory is always an attractive and inviting room, but these extreme temperatures make it impossible to relax in. An air conditioning unit the ideal solution for this problem.

Effective cooling
Air Conditioning is the only way of cooling your conservatory effectively. In cooling mode, the heat inside your conservatory is absorbed by the refrigerant circulating through the indoor mounted unit and taken via the connecting pipe work to be released outside.

Economical heating
Heat pump air conditioning units allow the cooling cycle described previously to be reversed. A heat pump extracts “free” heat from the outdoor air and transfers the heat indoors. The running costs are up to five times less than conventional heating systems.
