Gas Boilers

  1. 1. GAS BOILERS<br />
  2. 2. Gas Boilers are known for their saving money & energy quality. Though inefficient boilers should be avoided for the betterment. It is durable if maintained properly. <br /> Lot of modifications have been made to make these boilers absolutely perfect. <br /> Among these, one such plus point is its hot surface igniter, which helps in avoiding the pilot completely.<br /> Getting energized electronically, the igniter ignites the gas instantly. The vent dampers in them prevents excess loss of heat in the flue when the main burner is switched off. <br />
  3. 3. Types of Gas Boilers<br />Conventional Gas Boilers<br />Heats the water which is burn fuel in a combustion chamber surrounded by a water jacket.<br />This heats the water, which is then dispersed around the heating system.<br />Though its not necessary that all heat produced would be used for this purpose as mostly its lost to the surrounding air. <br />Therefore, condensing boilers extract more heat from fuels.<br />
  4. 4. Combination Gas Boilers<br />Combination boilers provide both instant hot water and central heating, but not at the same time - they are "hot water priority", which means that when hot water is being run there is no heat output to the radiators.<br />This also means they have low water rate, so they can only feed one tap at a time.<br />
  5. 5. Provide two things at the same time & instant hot water and central heating. <br />They do not occupy much space.<br />Their installation is not at all complicated.<br />Though they are quite expensive when it comes to their maintenance.<br />
  6. 6. Benefits of Combination Gas Boilers:<br />Instant, unlimited domestic hot water<br />Compact, easy to fit if space is limited<br />Disadvantages:<br />Unable to run multiple showers or baths at the same time <br />Lower flow rate for hot water than an open vent or system boiler <br />
  7. 7. System Boilers<br />Are equipped with extras built in necessary to fit to a sealed & fully pumped system.<br />They are larger in size but their installation is absolutely easy. <br />They are cheap & dependable boilers. However, their installation will give one a run for their money! <br />
  8. 8. A system boiler is like a low water content boiler, but have all the necessary extras built in to fit to a sealed, fully pumped system.<br />Provides central heating and hot <br />water via a storage cylinder housed in an airing cupboard - no need for water tanks in the loft, as with an open vent boiler.<br />
  9. 9. Benefits of System Boilers: <br />High flow rate for domestic hot water <br />No tank(s) in loft <br />More than one hot tap / shower can easily operate at same time <br />Disadvantages:<br />Hot water is not instant. <br />Once the water in the storage cylinder runs out you have to wait for it to reheat. <br />Need to find space for the cylinder (usually an airing cupboard) <br />
