It is not only this century and the last, that man has tried to heat their houses and water.
Throughout history humankind has attempted to heat their homes, 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 heat up their public baths and villas and the Spanish radiated their floors using a system locally referred to as ‘gloria’, which used hay being a combustible.
Throughout the middle ages, when fireplaces began to become popular, heating systems became virtually unknown. Until in 1777, William Murdoch learned that gas might be used for light. Then in 1824, the birth of gas cooking emerged, and naturally evolved to be 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 idea of heating water with gas. Although, Maugham didnt realise it, the technology of heating our homes nowadays came to be. He is generally accepted since the inventor from the Combination ‘Combi’ Boiler, that he called “the Geyser”.
Maugham invention disappointingly, was seen as dangerous as well as a health risk since it had no temperature controls so scalding was possible plus it had no flue for ventilation, meaning people may be in contact with lethal emissions. He had not been an engineer and would make little or no money from he’s invention.
Nevertheless in 1889, 21 years later a Norwegian Engineer Edwin Ruud discovered Maughams ‘Gas Geyser’ prototype and after studying the design plans and building 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 united states, and was exported to Europe where it was highly popular, however in the united kingdom, lots of people prefered the conventional system boiler which utilized space within the loft and allowed lots of people to bathe simultaneously. It is only within the last 10-20 years that Combi Boilers Yorkshire have started to emerge as the main boiler system throughout the uk, attributed with well over 50% of new boiler installations.
Probably the most commonly asked questions i get asked is: why there is no hot water inside my taps? To be able to diagnose this challenge we have to establish the type of home heating system which is installed on the property involved. Generally there will be many options to select from such us: instantaneous electric 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 combination of articles will handle the most common systems in UK starting with combination boilers also called ‘combi’ boilers. Other systems we will discuss in further submissions are:
No warm water on combination boiler. The first thing to check in case there is no very hot water on combination boiler is to see if it works in central heating system mode. To do that you will need to ensure that your wall mounted thermostat is calling for heat. Additionally you could have a programmable thermostat. If so ensure that it really 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 will not operate in both warm water and heating modes there are several steps which can be performed by the homeowner before calling a heating engineer to get rid of most obvious possible causes. Combination boilers require typically 1 bar pressure in central heating system to operate satisfactorily. Search for a pressure gauge on the front from 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 which may be the reason for boiler not firing up within both domestic very hot 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 has been detected next step is to top up system pressure. Majority 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 necessitates that filling loop ought to be detached and left through 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 now have our filling loop in position.
Some filling loops may 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 turn them off and on.
Bear in mind that some combination boilers rather than fitted with filling loops. The most effective example is Worcester Bosh CDi selection of boilers that require a special plastic factor 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 cost benefits and the ever growing necessity for more storage space in their homes compared to the inefficient, high running cost and huge storage needs in the traditional system boilers.
