Pros/Cons Of Various Gas Boiler Installations
- Ideal For smaller Homes
- Can easily fit in cupboard/under stairs/loft, no need for separate water tank- space saving.
- Instant hot water due to integral heat exchanger to heat water from mains supply.
- Simple installation of single unit.
- Easy to maintain.
- Reduced water flow rates when hot water at two or more outlets is used simultanouly. For example, two showers at the same time.
- Needs adequate water Pressure to function properly.
- Not compatible with solar water heating systems.
Conventional Boiler
Advantages
- Work well with older heating systems as they don’t rely on mains pressure.
- Suitable for homes with greater hot water demands as they provide a higher flow rate.
- Lower replacement costs as regular/conventional boilers are generally the cheapest type of boilers to buy.
Conventional Boiler
Disadvantages
- Hot water isn’t always available on demand, so you may need to wait for a shower.
- Regular boilers are less efficient than combi boilers because of heat loss when water is stored in the cylinder.
- You’ll need plenty of space to house the hot water cylinder and cold water tank.
- Suitable for properties that need a lot of hot water simultanously e.g. more than one bathroom.
- doesn’t have Feed and expansion tank
- Works well with underfloor heating.
- Pumps, valves built into the boiler system.
- Also referred to as closed-vent or system sealed boilers.
System Boiler
Disadvantages
- The water flow rate depends on the mains pressure. If there’s low pressure in your area, the water flow rate throughout your home will be worse.
- Space for the hot water cylinder, for example, an air cupboard.
- If you use up all the hot water in the cylinder, reheat will take a while.
Where a Combi Boiler installation is a possibility but the water pressure is low, we have WRAS-qualified contractors who can upgrade the coming cold mains service pipe. Alternatively, pumps and accumulator tanks can be used.
