It is not only this century and the last, that man has attempted to heat their houses and water.
Throughout historical past human beings has tried to heat their properties, cave men with the fire. Ancient Asians used hearths and stoves to heat water or air, channelled through their floors. While the Romans used hypocausts to warm up their public baths and villas and also the Spanish radiated their floors using a system locally called ‘gloria’, which used hay being a combustible.
During the middle ages, when fireplaces begun to become popular, heating systems became virtually unknown. Until in 1777, William Murdoch learned that gas may be utilized for light. Then in 1824, the birth of gas cooking emerged, and naturally evolved to become employed 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 born. He is generally accepted since the inventor of the Combination ‘Combi’ Boiler, which he called “the Geyser”.
Maugham invention disappointingly, was seen as dangerous along with a health risk as it had no temperature controls so scalding was possible and it also had no flue for ventilation, meaning people could be subjected to lethal emissions. He had not been an engineer and would make virtually no 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 style plans and making a few improvements, Ruud launched he’s own water heater in the US, after emigrating from Norway. Hes new Ruud Manufacturing company had been a huge success and is still running today in Pittsburgh.
Initially, a combination boilers were popular in the united states, and was exported to Europe where it absolutely was highly popular, however in the united kingdom, many individuals prefered the standard system boiler which utilized space in the loft and allowed many individuals to bathe simultaneously. It really is only during the last 10-20 years that Combi Boilers Yorkshire started to emerge as the number one boiler system in the united kingdom, attributed with more than 50% of all new boiler installations.
Probably the most commonly asked questions i get asked is: why there is not any very hot water inside my taps? In order to diagnose this problem we need to establish the sort of heating system that is installed at the property under consideration. Generally you will see many options to choose 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 series of articles will handle the most common systems in UK beginning from combination boilers also called ‘combi’ boilers. Other systems we will discuss in further submissions are:
No hot water on combination boiler. The first thing to check in case there is not any hot water on combination boiler is to determine if it functions in central heating system mode. To accomplish that you will want to make certain that your wall mounted thermostat is calling for heat. You also may have a programmable thermostat. In that case ensure that it is set to constant on central heating system mode. If boiler fires up we can suspect that a diverter valve is stuck on heating mode. A visit from an engineer will be required to replace this part.
If combination boiler does not operate in both hot water and heating modes there are a few steps which can be done by the owner before calling a heating engineer to get rid of most apparent possible causes. Combination boilers require on average 1 bar pressure in central heating system to operate satisfactorily. Choose a pressure gauge on the front of the boiler or sometimes on central heating system pipe work.
Most boiler makes could 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 reason behind boiler not firing up both in domestic warm water and heating modes. By low we understand below marked field on the gauge. Most boilers will not fire up if pressure drops below .5 bar. If low pressure continues to be detected following step would be to top up system pressure. Most of boilers on the market would have been fitted having a filling zdodxn that comprises of no.2 valves along with a flexible metallic connector. Good plumbing practice necessitates that filling loop should be detached and left through the boiler with no.2 valves capped of to avoid accidental over pressurising the program and leaks from PRVs (Pressure Relief Valve). In fact however 90% of installation have filling loops attached. Let’s assume we have our filling loop set up.
Some filling loops will have a singel tap while other could have 2 taps or a flat screwdriver point. On single tap ones it is sufficient to turn one tap on. On filling loops with 2 taps you should turn both on. On filling loops without taps you might need a small flat screwdriver to change them off and on.
Be aware that some combination boilers and never fitted with filling loops. The most effective example is Worcester Bosh CDi variety of boilers that require a special plastic key to top them up.
With energy prices rising year on year many individuals have prefered the combi boiler because of its advancement in efficiency, energy cost savings and the ever growing necessity for more storage area in their homes when compared to the inefficient, high running cost and huge storage needs from the traditional system boilers.
