New boilers are gas cost-efficient

September 23, 2008 at 7:58 am · Filed under boilers ·Tagged , ,

Many dwellings are currently centrally heated. With a couple of small changes to the central heating controls the system can be made much more energy efficient. Installation of a basic timer or a more complex heating system programmer will allow you to moderate when the heating and the hot water are operating. Fixing the periods when energy is actively being used will definitely cut your charges.

Room thermostats which automatically turn the heating off at a particular temperature will also preserve energy. energy use is limited to that required to preserve in the room warmth level at the set level. Each areas temperature can be individually manipulated by fitting radiator thermostat valves. This is a recommended way of holding the bedroom temperatures lower than that in the ground floor areas.

One of the main causes of high fuel costs and a leading source of energy inefficiency comes from aging boilers. A heating boiler has a typical lifespan of 15 years. New, modern boilers have more efficient designs and use less gas. Condensing gas boilers will use up to forty percent less energy. Exhaust gas heat is used to heat cold water trimming the gas consumption profile of the gas boiler. Government awards are often accessible for homes that install one of these type of new gas boilers.

The benefits of a powerflush

June 19, 2008 at 3:31 pm · Filed under heating ·Tagged

With  time your heating system could experience an accumulation of  contaminants.  The contaminants will need to be flushed out to restore your system to normal operation.

You can employ a powerflush service to remove this sludge and revitalise your gas fired boiler and system.

The buildup of sludge is a function on the heating process and therefore most types of boiler and central heating system can be impacted, older heating systems seem to suffer more. If you buy a replacement heating boiler you certainly should consider flushing the heating system first. Installing new components disturbs the existing system stirring up sludge and debris.

It is beneficial to add corrosion inhibitors to your heating system to slow this build up of contamination .

Some other problems which can be converted with a power flush are listed below : -

* buildup of contaminants in your gas fired boiler
* central heating water pump circulation problems
* clogging pipework
* corrosion impacting the heating system inside
* boiler and system blockages
* internal knocks and banging

As a consequence the advantages of the power flush could be :-

* radiator heating efficiency improvements as cold areas are eliminated
* improved central heating system efficiency so reducing fuel costs in future years.
* reduced energy consumption with improved heat exchanger performance
* cuts hydrogen gas build up which can lead to heating radiator corrosion and reduced heat output

The power flush is conducted by use of a powerflush machine. The gas fired boiler and system sludge  is filtered out as it is routed through the simple machine. The cleaning process is finished by the cleansed water being flushed through your boiler and system. The engineer will usually top up the heating system by adding a corrosion inhibitor to protect it in future years.

A power flush be finished by a trained operator to guarantee that it is completed correctly and does not create a mess.

The primary forms of central heating systems

June 7, 2008 at 10:08 am · Filed under boilers ·Tagged , ,

Buying a new central heating system is not a straightforward thing, you first need to interpret what form of system is best suited to your family. This paper will help you to visualise the options available to you. Most if not all of these Central Heating System comprise of a gas fired boiler, radiator and piping.

In northern Europe the primary family system will be the heating system probably powered by a combi boiler, although there is much talk of world-wide warming at the moment there is little mass demand for air conditioning systems. Virtually all new housing developments incorporate central heating systems as a familiar fixture within the household.

The value of central heating systems is fully realised in winter although most are also used to provide hot water every day of the year. A new central heating system can give your dwelling house the ambiance you are looking for. Another essential role for the central heating system is to create hot water. You need heating and hot water every day so you need a system that you can depend upon. You want to match the central heating system to your household needs so that it both meets your needs and uses energy efficiently.

There are two primary types of Central Heating System; pumped/vented and sealed systems.

The most usual type is a pumped/vented system. This type of system has a feed and expansion tank in concert with a hot water cylinder. Water expands when warmed and the expansion tank allows for this. The expansion tank is placed high up in the house often in the attic.

A slightly newer, more up-to-date system that several people are choosing over a pumped/vented central heating system is a sealed system. An advantage of a sealed system is that it has no requirement for an expansion tank. The water for a sealed Central Heating System is rendered direct from the main water supply. It feeds directly from the main water supply. if you embrace this system you don’t need to use your loft for housing in the expansion tank thereby saving space, the whole system is sealed, its unvented, which has its benefits:

- as the piping is removed from the attic it will not be at risk of freezing in the wintertime

- there are fewer system elements reducing any upkeep requirements

- less chance of piping developing leaks

- reduced risk of air locks, corrosion and gunk as there is not a chance of air being drawn down into the system through open vents as the system is sealed

It is usual for the water supply pressure to change and that this is dealt with by incorporating a pressure vessel. Safety valves open if the internal pressure is too high. Other automated valves open to allow the inner water in the boiler to be topped up if it drops to low.

Save money with a combination boiler

June 6, 2008 at 9:08 am · Filed under heating ·Tagged , ,

Maturing economies around the planet on going up need for energy resulting in higher heating costs.  To stop the year on year increases you need to consider how you are utilizing energy. You could trim your gas bills by up to 35% if you fit a new energy-saving condensing combination boiler.

Operating in the background your present-day gas fired boiler will be heating your home and providing hot water for washing cutlery and clothing in addition to powering your bath. Boilers have a life-time of 15 years.  Even though your current heating boiler may be running correctly it could be inefficient in comparison to the latest one.

You need to deliberate whether it is economic to continue with your older heating boiler as it reaches the end of its lifetime rather than changing to a new replacement boiler and savoring the increased energy efficiency. This can reduce your fuel costs down considerably. The most familiar boiler type is a condensing combination boiler which is well suited to smaller families who don’t need large amounts of hot water in a short space of time. A combi boiler takes cold water from the mains and heats it as required thereby eradicating any requirement for the hot water storage cylinder. If you have a gas combi boiler you will find that hot water may not be ready in the kitchen if you are filling a hot bath as it heats the hot water as necessary.

A typical gas fired boiler will use a hot water cylinder to store hot water it produces during the daytime.  You will get heat loss and gas releases even though the hot water tank is insulated.  If you have a smaller home you will find that you could have other uses for the space that the hot water tank takes up.

You can get efficiencies of up to 60 % by putting in a gas combi boiler and getting rid of the hot water storage tank. The standard gas combination boiler does lose energy through the hot exhaust gases. This can be taken by a condensing gas combination boiler which is even more economic.  The extracted warmth is then used to heat water saving gas usage.
