It is not only this century and the last, that man has attempted to heat their homes and water.
Throughout history human beings has tried to heat their houses, cave men with the fire. Ancient Asians used hearths and stoves to heat water or air, channelled through their floors. Whilst the Romans used hypocausts to warm up their public baths and villas and the Spanish radiated their floors with a system locally known as ‘gloria’, which used hay as a combustible.
During the middle ages, when fireplaces began 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 become 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 concept of heating water with gas. Although, Maugham didnt realise it, the technology of heating our homes today was created. He is generally accepted as the inventor in the Combination ‘Combi’ Boiler, which he called “the Geyser”.
Maugham invention disappointingly, was viewed as dangerous and a health hazard since it had no temperature controls so scalding was possible plus it had no flue for ventilation, meaning people may be exposed to lethal emissions. He was not an engineer and makes little if any money from he’s invention.
However 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 hot water heater in the US, after emigrating from Norway. Hes new Ruud Manufacturing company was a huge success and is still running today in Pittsburgh.
Initially, the mixture boilers were popular in the united states, and was exported to Europe where it absolutely was highly popular, however throughout the uk, many people prefered the traditional system boiler which utilized space within the loft and allowed lots of people to bathe simultaneously. It really is only during the last 10-15 years that Combi Boilers Yorkshire began to emerge as the number one boiler system in the united kingdom, attributed with well over 50% of all new boiler installations.
One of the most commonly asked questions which i get asked is: why there is absolutely no hot water in my taps? So that you can diagnose this challenge we must establish the sort of home heating system which is installed at the property under consideration. Generally you will see several choices to choose from such us: instantaneous electric water heaters (electric), instantaneous gas water heaters, storage water heaters, electric showers, gas fired combination boilers, gas fired traditional boilers and hot water cylinder, unvented warm water cylinders and variations on above.
This combination of articles will handle the most common systems in UK beginning with combination boilers also known as ‘combi’ boilers. Other systems we are going to discuss in further submissions are:
No warm water on combination boiler. The first thing to sign in case there is not any very hot water on combination boiler is to find out if it works in central heating system mode. To do that you will want to ensure that your wall mounted thermostat is calling for heat. You also could have a programmable thermostat. If so 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 hot water and heating modes there are a few steps which can be done by the property owner before calling a heating engineer to remove most apparent possible causes. Combination boilers require typically 1 bar pressure in central heating system system to work satisfactorily. Search for a pressure gauge on the front from the boiler or sometimes on central heating 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 for 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 has been detected next phase is always to top up system pressure. Majority of boilers on the market might have been fitted with a filling zdodxn that consists of no.2 valves as well as 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 prevent 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 may have a singel tap while other may have 2 taps or perhaps a flat screwdriver point. On single tap ones it is enough 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 change them on / off.
Be aware that some combination boilers and never fitted with filling loops. The best example is Worcester Bosh CDi selection of boilers that require a unique plastic answer to top them up.
With energy prices rising year on year many individuals have opted for the combi boiler because of its advancement in efficiency, energy financial savings as well as the ever growing need for more storage space in their homes when compared to inefficient, high running cost and huge storage needs of the traditional system boilers.
