This can cause all sorts of problems such has uneven flow around certain areas of radiators in your property or huge cold spots on radiators where the circulating water goes around the edges of the radiator and don’t have an easy path through the centre because of the blockages.

If the system is full of sludge then the pump will be straining to push the water around correctly and will eventually fail. Boiler heat exchangers can also become very badly ‘furred up’ as a result and in extreme cases thin can result in the boiler being replaced completely.

Typically Powerflushing takes around a day and doesn’t involve taking the radiators physically off the walls.

Powerflushing machines attach onto the pipe-work and each individual pipe run to a radiator is turned off except for the one you’re intending to flush. This pipe-work has water and a cleansing agent forced through it at considerable pressure in both directions, typically the water in the flusher goes black very quickly as the deposits are extracted and then dumped into the reservoir.

Once the flushing has been carried out on each required radiator and the hot water cylinder indirect loop then the system is drained and then refilled with cold water.

The system is bled of all air & then tested for heat transfer around the circuit. Any immediate problems are resolved then.

The final drain down and refill allows for a chemical ‘inihibitor’ chemical to be inserted into the system to prevent the build up of debris in the future.

Powerflushing typically costs around £400 or more, depending upon the number of radiators.

With many new houses now boasting two or more bathrooms, along with an impressive array of systems that use hot water (Jacuzzi, jet shower), users do not accept a system that cannot cope with the hot water demands of modern life. With long working hours, time in the home is valuable and people these days do not want to wait for the hot water, nor do they accept a trickle form the hot water shower. An unvented cylinder and central heating system is the answer, providing virtually unlimited volume of hot water, in a convenient pressure for the shower or any other domestic use.

There are three main groups of materials that are used in the manufacturing of unvented cylinders. Each of these has their respective advantages and disadvantages. The three types of materials are copper, Stainless Steel and sheet metal.

* Copper cylinders – the lightest material, and used to be relatively cheap until the recent sharp increase of the commodity prices of copper. Still they are very popular in the UK, despite having the lowest heat retention properties of the three.

* Stainless steel cylinders – provide middle ground in terms of heat retention and weight, compared to copper and sheet metal. They are the most expensive type, but offer the longest lifetime guarantee (normally around 20-25 years).

* Sheet metal cylinders – the most popular type in most European countries and the cheapest of the three. Inner enamel glazing ensures virtually no build up of scale. They provide the highest heat retention performance of the three, but also are the heaviest.

There are several important parameters to remember when choosing your unvented hot water cylinder:

* Volume and external dimensions – a typical household (4-5 people) in the UK will require a 200 liter cylinder. However, the cylinders come in different shapes and dimensions. Make sure to check the width and height of the cylinder, so that it fits in the airing cupboard (or any other space you plan to position the tank in).

* Heat retention properties – check the heat loss specifications of the cylinder. A good cylinder will lose very little heat (e.g. less than 3 kW per 24 hours). This will reduce energy wastage and cut your heating bills.

* Warranty and after-service – unvented hot water cylinders have good record of long life and little in the way of faults. Nevertheless it is important to check what warranty and service you get from the manufacturer.

References from neighbors, family and friends may be the best way to go when out looking for plumbers. Although not all of these people may have a good recommendation or may not have any idea who to recommend at the moment, there may be one or two who has a plumbing specialist on their phone book. In case of emergencies, one may not be as picky as one would like to be but it is advisable to be always on hand to monitor the plumber during work as well as to ask how much the labor and materials may cost before any repair is started.

A homeowners association may also have someone who specializes in these services on hand for emergencies. Some associations actually charge their members for such services, having a plumber on call. Others have a short list of professionals to choose from which may be approved by the homeowners every year. Having a builder friend or acquaintance may also help since contractors usually deal with plumbers when constructing a building. The problem with this type of recommendation is that the specialist may have a lot of pending work and will not be able to accommodate emergencies.

It is also useful to make sure and be clear with regards the actual cost of the materials and labor before allowing the professional to start working on the emergency or the job. Unscrupulous individuals may answer vaguely or appear confused with regards the cost and then charge an arm and a leg when the job is done. Others will quote just the material cost and then hit you with the labor cost after the job is finished. Reliable professionals will most likely give a ceiling price or a rough estimate which should be close to the actual price. If the damage is not clear until the wall is uncovered, the plumbing specialist may need to view the actual damage before quoting a price.

Hot Water Cylinder Insulation

New cylinders should be insulated with a bonded foam jacket on to the outside of the cylinder, these are extremely efficient and will keep the water hot for a long time.

Hot water cylinders without a bonded foam jacket should be insulated with a glass fibre jacket. An 80mm thick jacket will cut heat loss by up to 75% and are very cheap at around £10.

Types of Hot Water Cylinder

There are many different shapes and sizes of cylinder to suit the space available such as an airing cupboard. The capacity of the cylinder is important which is measured in Litres. The required size for your property will depend on the number of people living in the house and water needs, your plumber will be able to advise you on the best size for your property.

There are many types of cylinder available, the 5 main types of cylinder are: -

Direct – which are only for use with Circulators because the water is heated directly.

Indirect – which are for use with any type of central heating system. This is because the water from the central heating goes through a coil of pipe within the cylinder (giving its heat up to the water in the cylinder) but doesn’t mix with the water in the cylinder. This type of cylinder usually has an air bleed on a pipe at the side, often the pump and motorised valves are located in the same cupboard

Primatic (self priming) – only for use with gravity systems because the water for the central heating is taken from within the cylinder, and is only separated by an air lock (system additives must not be used with this type of cylinder as this will come out through the hot taps)

Thermal Storage – a large type of cylinder were the main cold water is passed through a coil of pipe within the cylinder taking its heat from the thermal storage and supplying the hot taps. The central heating circuit is also taken from the cylinder.

Unvented Cylinder – This is the same as an indirect cylinder except there isn’t a header tank, and it’s connected directly to the main water supply giving mains water pressure to the hot taps and showers. This is probably the future standard because of the reliability and true mains water pressure. They come in various sizes and are ideal for the larger home.

There will be other factors you will need to consider, such as family circumstances before you make your decision. You will need to consider your future at the property, and whether or not your family size is likely to increase. You should consider the following:

• What are your long term plans for the property?
• Do you intend to use it as a family home or will it simply be used as an investment property?
• Are you likely to use large quantities of hot water?

It is important to also select the appropriate size of the water heater as this way you will be able preserve energy. A good alternative would be to purchase a space-saving gas or electric on-demand system in which cold water is heated as needed. This can be quite good as no energy is wasted in keeping the water hot, the unit does not take up much space as it has no storage tank, and you will never run out of hot water. However, if you will be using appliances at the same time, such as a washing machine and a dishwasher, you will need to purchase more than one.

Solar water heater – good alternative?

Another option would be to install a solar water heater. If you decide to go for this option, you may need to increase your financial budget as the installation and purchase price will be high. On the other hand, it may suit you better in the long run as you may save on operations costs.

If you decide to install a full central heating system, then this is likely to add value to a property irrespective of age. On the other hand, if you have a small one bedroom apartment, installing an instantaneous heater will be more practical and appropriate. It is beneficial to consider a range of factors before reaching your decision. You will need to consider:

• Initial installation costs
• The costs involved in connecting the fuel type to the water heater
• Maintenance costs over a period of time

Generally there are a wide range of heating systems available to suit different needs. It will all depend on your own personal preference, and how much you are willing to spend.
