Conventional Boiler – Gas Heat Only Boilers

 

A conventional boiler comes with a hot water tank or cylinder where hot water is kept. Gallons of water can be heated, stored and readily used. Cold water from the tank is heated up in the hot water storage cylinder, which feeds into the household's taps and faucets.

The water tank in the loft maintains the right water level whilst a pump circulates the hot water to your home's radiators. Conventional boilers (also known as regular boilers, heat only boilers or open vent boilers) are designed to provide both heating and hot-water with the use of an additional cold-water tank and hot-water cylinder.

Conventional boilers are great for larger homes and those with more than one bathroom. Just bear in mind that you will need enough space for the hot and cold water tanks and that you can’t get hot water on demand like you can with a combi boiler.

 

Disadvantages Conventional Boiler

  1. Pressure flow for showers and hot water can be low.
  2. You’ll need space for the hot and cold feed tanks.
  3. Conventional boilers aren’t as efficient as combi boilers – there will be heat loss as hot water is stored.
  4. Your hot water can run out and take time to reheat.
  5. Hot water isn’t supplied on demand – you need to heat it in advance.
  6. You’ll need space for the hot and cold feed tanks.

Advantages Conventional Boiler

  1. They still work well even if your mains pressure is low.
  2. You’ll still get hot water even if someone is running the shower and the kitchen taps at the same time.
  3. They’re easy to maintain as they have a simple design.
  4. You can install an immersion heater to the hot water cylinder to use if the boiler breaks down.
  5. Conventional boilers are compatible with older central heating systems.
  6. You can install an immersion heater to the hot water cylinder to use if the boiler breaks down.
