Our Service

Installing a boiler or full central heating system, is an important investment. Done well, it could save you money on your energy bills, and add value to your home, so it's important that you make an informed decision and have the work carried out by experts. At Diamond heating, we can help you find a reliable, affordable and energy efficient solution to your needs. We supply and install a wide range of boilers and controls. We are not tied to one manufacturer, which means we will recommend a boiler to suit the application, not one that suits us.

Below, we have listed some of the terms used in our quotation, to help you make an informed decision.

Power Flushing

Whenever a new boiler is installed, it is a requirement of the manufacturer and the building regulations that the system be cleaned. This is to remove any loose oxide debris, sludge or other contaminants that are in the system, and stop them from blocking your new boiler. All new boilers have much narrower waterways than their older counterpart, so will block fairly easily if this is not done.

To do this, we connect a power flushing machine and use system cleaning chemicals to remove as much of this debris as possible. This can also help to improve the efficiency/ heat output of your radiators. Once the work is complete, we add an inhibitor chemical to help prevent further build up.

Magnetic System filter

The vast majority of debris in a heating system is metallic, caused by ongoing corrosion of the radiators. No matter how well a system is flushed, it is inevitable that some debris will remain. A magnetic filter is fitted to the system before the boiler to capture this debris, which is then removed on your annual service. This gives maximum protection to the boiler and helps keep the system working efficiently.

Thermostatic radiator valves

The building regulations require all heating systems to have thermostatic radiator valves fitted to at least some of your radiators. They give a greater degree of control over your heating system.They allow you to have a different temperature in each room. This will conserve energy, as radiators are not on if they are not required, saving energy and money. Good for you, good for the environment.

Boiler controls including boiler plus

Recent changes to the building regulations mean all new boiler or system installations require the system to have a minimum of time and temperature control, also known as boiler interlock. In addition, combination boilers must also have one of the following:

  • Weather compensation
  • Load compensation
  • Flue gas heat recovery
  • Smart controls with automation and optimisation

These controls will minimise the boilers operation and reduce gas consumption.

In most cases, these controls are wireless, so can be sited anywhere that is convenient, reducing the need to run additional unsightly wiring.

Boiler/System commissioning

Once the boiler or system has been installed, it has to be commissioned. This means it has to be run and tested to ensure that the boiler and controls etc are working correctly. The boiler flow and return temperatures are tested, the gas rate of the boiler, the hot water flow rate and the hot and cold water temperature difference, (combination boilers only) and the flue gas products are then tested with a flue gas analyser, to ensure the the boiler and system are operating safely, efficiently and according to the manufacturers installation instructions.

The boiler installation is then notified to building control via Gas Safe register, who will issue a certificate to verify that the installation has been carried out correctly by a registered engineer.

I hope you find this information helpful. If there is anything you are not sure of, or if you require any additional information, please don't hesitate to contact us and we will be happy to answer any questions you may have.

Thank you.
