Combination Boilers and how they Work
Mains pressure water comes into the boiler and is heated by passing through a mini cylinder. The flow of water from the mains switches on the burner the pump and a diverter valve, which sends water from the heat exchanger around the cylinder and back again. When central heating is required, the electronic programming is required, the electronic programmer
Switches on the burner and rammer switches on the burner and heating circuit. The expansion in the heating system as the water gets hotter is taken up by a pressure vessel inside the boiler casing. This extra pressure is higher than that of an open vented system and requires good quality radiator valves to pre* vent small leaks. Although combination boilers are methodically finishing each connection before starting the next. The mains water The boiler should have a strainer fitted into the pipe work at some point to keep small through a hosepipe with a permanently connected double-check valve assembly. This is connected temporarily from the rising main to a valve on the heating circuit.
By far the most complicated of all boilers in terms of what lies within their casing, from an installation point of view they could not be more straightforward. The confusing maze of pipework inside the boiler eventually comes out of the bottom all clearly market and ready for connecting to and ready for connecting to the: system with compression fittings.
If all the pipes to the boiler are run in the right order so there is no need for any last-minute ducking and diving, the finished job will be neat. Once the boiler has been hung on the wall with the flue in place, screw a row of Pipe brackets into the exactly below the connections, so all pipes come up parallel. The pipes can be run in any order but it is often best to work through particles out of the gas/water valve is usually incorporated in the connector. If it is not, fit one immediately before connecting to the boiler.
In this computerized age modern central heating controls have become very sophisticated. Or companies may offer to update your existing controls with ‘electronic energy management systems’ that claim to save up to40 percent of your fuel bilIs. depending on the cost installation it may take several years to recover your costs, by which time you may need a new heating system anyway. If a heating system is running at 40 per cent below efficiency because of inadequate controls, even if only during the summer, there is almost certainly something that can be done on a DIY basis to improve it dramatically. The pay-back period is likely to be months rather than years. Before deciding what improvements can be made, you will need to know how up-to-date your controls are or, for a new system what controls are needed.
