Artisan Plumbers :: Plumbing & Heating Engineers with 21st Century Artisan Skills.

Artisan Plumbers undertake Oil Fired Boiler installations in full compliance with the relevant Building Bye-Law Regulations.

The Boiler will be chosen to meet your requirements and the criteria to match CHeSS recommendations for good and best practice for the energy efficiency of domestic wet central heating systems.

Purchasers - Consumers should use these specifications to ensure their heating installations will conform to current good or best practice.

CHeSS was produced by the building research establishment BRECSU, in response to a request from the Heating Strategy Group of the Energy Efficiency Partnership for Homes, which recognised that one of the Key difficulties facing the domestic heating installation industry was a lack of common standards and understanding of what should be done to improve energy efficiency.

For almost 20 years, BRECSU has been promoting energy efficiency in buildings on behalf of the government. Since 1989, they have done this as managers of the buildings element of the Energy Efficiency Best Practice programme, on behalf of the UK's Department of the Environment, Transport and the Regions (DETR) and the devolved administrations.

Installation engineers should use them to quote for Boilers of defined quality, this will enable the consumer to make informed comparisons between competing tenders.

It explains to purchasers and suppliers how the efficiency-critical components should be specified, Artisan Plumbers follow those specifications in their design criteria..

Artisan Plumbers provide full system design and specification to meet your requirements.

Artisan Plumbers specification and design service Consultant will visit your home and discuss your complete Plumbing or Central Heating project.

Once we are sure you are satisfied we will provide you with a comprehensive quotation and specification ready for your consideration.

Condensing Boilers

In 2004 the UK Government predicted the UK’s native gas reserves would run dry in 12 years, the UK now imports more gas than it produces. This change from an exporter to an importer of gas has resulted in price rises, which can only get worse as demand for ever decreasing gas supplies increases. On 1st April 2005 it became law to allow the installation of only 'A' or 'B' SEDBUK rated boilers*. These A and B rated boilers use condensing technology to reach high efficiencies. High efficiency condensing boilers convert more than 88% of their fuel into heat, compared to 78% for conventional types.

A condensing boiler with a gas-to-water or primary heat exchanger, of which there may be more than one, has a larger surface area than it would within a non-condensing boiler. This extra surface area allows more heat to be extracted from the combustion process for the same amount of fuel that is consumed in a non-condensing boiler. They require less fuel to apply the same amount of heat to the system, producing less greenhouse emissions.

They are available as regular and combi models, floor standing or wall hung. Care is needed when siting the flue terminal, due to the plume effect. Pluming is the name given to visible flue products leaving an appliance terminal. When gas is burnt one of the products of combustion is H2O (water). In standard efficiency boilers, the flue gases leave the boiler at high enough temperatures for the water vapor to appear invisible. However, in high-efficiency condensing boilers, the flue gas temperatures can be significantly lower and as a result of this the water vapor in the flue gases appears as a mist leaving the terminal.

Manufacturers claim you can save over 30% on your fuel bills by switching to a condensing boiler from a standard efficiency model. In addition to this the installation of heating controls can give you up to an extra 10% saving – that’s about £150 - £180 off the average bill!

Care should be taken to ensure the boiler is installed in a clean system. A new efficient boiler on an old dirty system will not operate as effectively. The system may be corroding and may contain debris, which will inhibit the operation of the boiler. Corrosion reduces the fuel efficiency of the boiler, causes poor circulation to radiators and can lead to pump failure, heat exchanger and noisy operation. It is best practice to flush and chemically treat the system on installation of a new boiler.

*Because of installation requirements, some premises will qualify as an exception. This means a D or C rated standard efficiency boiler can be installed in these cases.

Energy Labelling

Energy efficient products are designed to make the most effective use of energy with the minimum of waste. This means that the amount of energy needed to run them is reduced compared to a standard efficiency product. To ensure you can identify energy efficient products you should look out for the EU energy label, the energy saving recommended logo and in the case of boilers, SEDBUK ratings.

The EU energy label rates products from A (the most efficient/least energy used), down to G (the least efficient/most energy used). These are used on items such as refrigerators, light bulbs, washing machines etc. Many pump manufacturers in the UK are also using energy labeling on their products so you can choose an efficient pump for your central heating system.
Boilers are rated according to how much of the fuel they consume is converted to heat, as a percentage. This rating is called SEDBUK - Seasonal Efficiency of Domestic Boilers in the UK. Like the EU energy label, SEDBUK ratings are from A to G, with A-rated boilers being more than 90% efficient. Standard efficiency boilers rate at band D, with their high efficiency counterparts rating at bands A and B.
