It is not only this century and the last, that man has attempted to heat their houses and water.
Throughout history humankind has made an effort to heat their houses, cave men with the fire. Ancient Asians used hearths and stoves to heat water or air, channelled through their floors. As the Romans used hypocausts to heat up their public baths and villas and also the Spanish radiated their floors with a system locally known as ‘gloria’, which used hay as a combustible.
During the middle ages, when fireplaces started to become popular, heating systems became virtually unknown. Until in 1777, William Murdoch learned that gas could be used for light. Then in 1824, the birth of gas cooking emerged, and naturally evolved to be utilized to heat homes and water for bathing. Surprisingly, baths were not used until 1850 when gas jets would heat the bath from underneath.
However, it wasn’t until 1868 when Benjamin Maugham, painter and decorator had the thought of heating water with gas. Although, Maugham didnt realise it, the technology of heating our homes in the 21st century was created. He or she is generally accepted as the inventor in the Combination ‘Combi’ Boiler, which he called “the Geyser”.
Maugham invention disappointingly, was considered as dangerous as well as a health risk because it had no temperature controls so scalding was possible plus it had no flue for ventilation, meaning people could be subjected to lethal emissions. He had not been an engineer and will make little if any money from he’s invention.
But in 1889, 21 years later a Norwegian Engineer Edwin Ruud came across Maughams ‘Gas Geyser’ prototype and after studying the design and style plans and making a few improvements, Ruud launched he’s own water heater in america, after emigrating from Norway. Hes new Ruud Manufacturing company had been a huge success and is also still running today in Pittsburgh.
Initially, the combination boilers were popular in the US, and was exported to Europe where it had been highly popular, however in the UK, many people prefered the traditional system boiler which utilized space in the loft and allowed many people to bathe simultaneously. It is actually only within the last 10-15 years that Combi Boilers Yorkshire have started to emerge as the number one boiler system throughout the uk, attributed with well over 50% of all the new boiler installations.
Probably the most commonly asked questions i get asked is: why there is no hot water in my taps? So that you can diagnose this problem we need to establish the kind of heating system which is installed in the property under consideration. Generally you will have several choices to select from such us: instantaneous electric hot water heaters (electric), instantaneous gas hot water heaters, storage water heaters, electric showers, gas fired combination boilers, gas fired traditional boilers and hot water cylinder, unvented very hot water cylinders and variations on above.
This number of articles will cope with the most typical systems in UK starting with combination boilers also referred to as ‘combi’ boilers. Other systems we are going to discuss in further articles are:
No warm water on combination boiler. The first thing to check in case there is not any hot water on combination boiler is to find out if it functions in central heating mode. To do that you will need to make certain that your wall mounted thermostat is calling for heat. In addition, you could have a programmable thermostat. In that case make sure that it really is set to constant on central heating mode. If boiler fires up we can suspect that the diverter valve is stuck on heating mode. A visit from an engineer will be asked to replace this part.
If combination boiler does not operate in both very hot water and heating modes there are a few steps that can be performed by the homeowner before calling a heating engineer to eliminate most apparent possible causes. Combination boilers require on average 1 bar pressure in central heating system system to function satisfactorily. Choose a pressure gauge on the front in the boiler or sometimes on central heating system pipe work.
Most boiler makes may have markers in green or red pointer (as on the picture) showing required system pressure. If system pressure is low then that may be the explanation for boiler not firing up in both domestic warm water and heating modes. By low we understand below marked field on the gauge. Most boilers will never fire up if pressure drops below .5 bar. If low pressure has become detected next phase would be to top up system pressure. Greater part of boilers on the market could have been fitted using a filling zdodxn that comprises of no.2 valves and a flexible metallic connector. Good plumbing practice requires that filling loop needs to be detached and left by the boiler without.2 valves capped of in order to avoid accidental over pressurising the system and leaks from PRVs (Pressure Relief Valve). In fact however 90% of installation have filling loops attached. Let’s assume we have now our filling loop in position.
Some filling loops could have a singel tap while other might have 2 taps or even a flat screwdriver point. On single tap ones it is sufficient to turn one tap on. On filling loops with 2 taps you will need to turn both on. On filling loops without taps you may need a small flat screwdriver to turn them off and on.
Bear in mind that some combination boilers rather than fitted with filling loops. The best example is Worcester Bosh CDi variety of boilers that require a special plastic answer to top them up.
With energy prices rising year on year lots of people have prefered the combi boiler because of its advancement in efficiency, energy cost benefits and the ever growing necessity for more storage area within their homes when compared to inefficient, high running cost and huge storage needs of the traditional system boilers.
