Central Heating Installations

The main part of any heating system is the boiler, so it is recommended not to tighten the budget when selecting a boiler. Should your boiler develop a fault, you will in most cases be left annoyed and uncomfortable. The better quality boiler you install, the better it performs, the more energy is saves and the more reliable it is.

There are other areas you can save costs on a new heating system; cheaper radiators, leaving some system pipe work in and not moving boiler position around for example.

 

 

A heating system is normally made up of a few key components:


  1. Boiler; this is the heat source, powered by gas, oil or LPG.
  2. Hot water cylinder; either unvented or vented (tanks in the loft).
  3. Radiators; these are fitted in each room and radiate heat produced by boiler.
  4. Zone valves; these control heat from the boiler reaching different heating circuits, i.e. radiator circuit and hot water circuit.
  5. Thermostatic radiator valves; valve situated at one end of a radiator, controls room temperature automatically.
  6. Room thermostat; situated away from boiler, detects overall temperature of property and shuts down boiler when set temperature is reached.
  7. Programmer; controls the on/off times of the boiler.
  8. Pump; pumps the central heating water around the system

Above is only a simplified explanation of what is involved and included in a central heating system. When we install a central heating system we always go to our set guidelines, which apply to most properties. To get an idea of what is involved during an install please see below:


  • Old system is drained down, boiler and flue are removed. If having full central heating system installed, we remove all old radiators and associated pipe work.
  • Supply and fit new radiators, radiator valves and associated system controls valves if need be.
  • Fit new boiler, alter any original pipe work to suit and change system to a sealed system set up. A condense pipe must be taken from the boiler to a suitable discharge point as well as the safety discharge pipe from the boiler. We recommend fitting a boiler on an outside wall wherever possible.
  • Once new boiler, pipe work and radiators are installed we fill the system with water along with a suitable central heating cleaner. We pressurise the system and check for leaks. Once all the system has been checked we perform a cold flush of the heating system to remove any debris and old water. 

 

 

 

  • Gas main is completed and tested to ensure its leak free. Electrics and controls are all wired together ready for commissioning.
  • We fire up the new boiler, testing for correct operation and complete the required Benchmark certificate. We then let the boiler run while we clean up and pack up.
  • Once the boiler has warmed the system fully, we check each radiator is working, check all system controls are working then we drain the system and perform a hot flush.
  • When system water runs clean we add central heating inhibitor and refill the system, venting any air and checking for leaks once again.
  • We explain how to use the system to you, show everything is working and give you all literature associated with our installation. We leave you warm and happy!

 

Installations vary greatly depending on what you have installed, what was previously installed etc. Above is only a guideline on what to expect.
