Choosing the right Boiler for your Home
Choosing the right boiler depends on your property and individual needs. Some important factors to consider:
- Position – wall hung or floor-standing models are available. The boilers distance from an outside wall or the roof will affect the type of flue you have (‘ Open ' or ‘ Room-sealed' ).
- Size of household – for example, does your boiler need to supply heating and hot water for a number of bathrooms?
- Running costs - look for energy rating labels to compare costs.
- Maintenance – some boilers require stringent servicing than others.
- Safety - all boilers require a regular service by a qualified professional. It is a legal requirement for
to be inspected by a qualified CORGI engineer annually. Boilers or flues must not be altered without seeking expert advice.
Pro's and Con's of Boiler Options
A cast iron heat exchanger heats the water, similar to a gas burner under a kettle.
- operates quietly and has reliable, easily understood controls
- huge range of sizes suit most properties
- fuel consumption is relatively high
The ‘Combi' will provide both hot water for you central heating and your taps.
- ideal for a flat or small house because the lack of tanks saves space
- instant hot water to your taps
- the internal workings are complicated and can be expensive to repair, so a maintenance contract or boiler insurance cover is advisable
- not highly suitable for a large house where a number of people require hot water at the same time
A modern gas boiler available for fully pumped systems or as a combination boiler.
- designed so that water returning from the heating system is used to cool the flue gases - this extracts heat which is normally lost
- works best with radiator temperatures of about 60 ˚C (140˚F), but even at a temperature of up to 80˚C (176˚F) they are significantly more efficient than other boilers
- requires a fan assisted flue
Traditional, combination and condensing boilers can be oil-fired. They are generally floor-standing, though some are wall-hung models.
- one of the cheapest heating fuels available
- servicing costs are generally higher and deliveries must be planned
This boiler type offers gas, oil or solid fuel consumption.
- a ‘cosy' look and feel as it includes a fire facility (solid fuel consumption)
- requires a natural-draught open flue
- solid fuel back boilers work only when the fire is lit so an electric immersion heater is needed for hot water in summer
