It is not only this century and the last, that man has tried to heat their homes and water.
Throughout historical past mankind has attempted to heat their properties, 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 using a system locally known as ‘gloria’, which used hay as being a combustible.
Throughout the middle ages, when fireplaces begun to become popular, heating systems became virtually unknown. Until in 1777, William Murdoch found that gas may be used for light. Then in 1824, the birth of gas cooking emerged, and naturally evolved to be used 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 concept of heating water with gas. Although, Maugham didnt realise it, the technology of heating our homes today came to be. He or she is generally accepted as the inventor in the Combination ‘Combi’ Boiler, that he called “the Geyser”.
Maugham invention disappointingly, was seen as dangerous along with a health hazard since it had no temperature controls so scalding was possible and it also had no flue for ventilation, meaning people could be in contact with lethal emissions. He had not been an engineer and will make little if any money from he’s invention.
Nevertheless 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 creating 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 mixture boilers were popular in america, and was exported to Europe where it had been highly popular, however throughout the uk, many individuals prefered the standard system boiler which utilized space within the loft and allowed lots of people to bathe simultaneously. It is only within the last 10-15 years that Combi Boilers Yorkshire started to emerge as the top boiler system in the united kingdom, attributed with over 50% of new boiler installations.
Probably the most commonly asked questions which i get asked is: why there is absolutely no warm water inside my taps? To be able to diagnose this problem we must establish the sort of home heating system that is certainly installed in the property in question. 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 warm water cylinder, unvented hot water cylinders and variations on above.
This number of articles will handle the most typical systems in UK starting with combination boilers also known as ‘combi’ boilers. Other systems we will discuss in further submissions are:
No very hot water on combination boiler. The first thing to sign in case there is no warm water on combination boiler is to see if it functions in central heating mode. To do that you will want to make sure that your wall mounted thermostat is calling for heat. In addition, you could have a programmable thermostat. If so ensure that it 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 required to replace this part.
If combination boiler will not operate in both very hot water and heating modes there are a few steps that can be done by the owner before calling a heating engineer to get rid of most apparent possible causes. Combination boilers require typically 1 bar pressure in central heating system to work satisfactorily. Choose a pressure gauge on the front in the boiler or sometimes on central heating system pipe work.
Most boiler makes will have markers in green or red pointer (as on the picture) showing required system pressure. If system pressure is low then that could be the reason behind boiler not firing up both in domestic hot water and heating modes. By low we understand below marked field on the gauge. Most boilers is not going to 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 could have been fitted having a filling zdodxn that includes no.2 valves as well as a flexible metallic connector. Good plumbing practice requires that filling loop should be detached and left from the boiler without any.2 valves capped of 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 place.
Some filling loops will have a singel tap while other could have 2 taps or perhaps 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.
Be aware that some combination boilers and not fitted with filling loops. The most effective example is Worcester Bosh CDi variety of boilers that require a unique plastic key to top them up.
With energy prices rising year on year many people have opted for the combi boiler due to the advancement in efficiency, energy financial savings as well as the ever growing necessity for more space for storage inside their homes compared to the inefficient, high running cost and huge storage needs in the traditional system boilers.
