Unfortunately, boilers do not last for ever. The useful working life is reckoned to be 15 years and older ones lose efficiency and become prone to breakdown, usually during those cold spells when you depend on your system to keep the house comfortable. That's the bad news: the good news is that modern boilers are so much more efficient, quicker to warm up, quieter in operation and cheaper to run. Your investment will quickly pay for itself.

If because of age, inefficiency or lack of capacity your current boiler needs to be replaced, we can advise you on the latest developments in boilers and tankless water heaters. See similar questions...

This is dependent on the challenges imposed on the cushion. The average person passes gas 14 times a day. Not all outbursts however will be made on the specialty formulated membrane and we therefore based our design criteria on five outbursts per day. Based on this, our sample study shows a life span of six months for a women and half that for a man. The technically advanced filter in GasMedic will last two to four times longer.

Vaillant's solar DHW heating system will provide around 50-60% of annual domestic hot water requirements, but an auxiliary power source is required to ensure there's always hot water on demand. In addition, the boiler is also necessary to operate the central heating system. See similar questions...

The boiler size needed depends on the construction of the house, the size and type of heating system, the geographical location of the house and the amount of radiation in an existing structure. Boucher Energy will perform a detailed heat loss to determine proper sizing. See similar questions...

That depends on whether you choose soft bifocals or GP bifocals. In general, soft contact lenses become cloudy with protein deposits over time; they are also easy to tear. GP contact lenses are made of a more durable plastic that stays clear over time. With GP bifocals, you may need new ones only when your presbyopia progresses so that you need a stronger near vision prescription. Read a comparison of soft contacts vs. GP contact lenses. back to menu See similar questions...

In most cases, you will need to install a chimney liner if your chimney has an over-sized or deteriorated terra cotta (clay) liner. You must always install a liner if you have an unlined masonry chimney. Both the National Fuel Gas Code (NFPA 54) and the national Installation of Oil-Burning Equipment code (NFPA 31) compel installations of the chimney liner in these circumstances. boilers have increased in efficiency, the temperature of the flues gases has declined.

Heating output is specified in kilowatts, kW, (metric units) or BTUs (Imperial units) and represents the rate at which the system can deliver heat energy. Sizing of heating systems should be done by a qualified heating engineer. It is dependent on many factors including levels of insulation and draught proofing of your home, lowest outside temperature of your locality and patterns of use. See similar questions...

The only way to determine what your actual requirement is to have a heat load done on your home by a qualified heating technician. This calculation looks at the size of the structure, insulation, doors and windows along with your climate area for outdoor design temperature. A heat loss is then calculated to determine what is required for the boiler and the heating elements to heat the structure. See similar questions...

This depends on what type of filter(s) you have, and the loading (loading refers to the amount of particles the filter has trapped). Essentially, you must replace the filter once it starts to reduce the air flow excessively. This can result in your furnace's heat exchanger over-heating, your safety limits getting damaged; it can even create a fire hazard1 It is also the leading cause of air conditioner services calls: a plugged filter can cause the evaporator coil to "freeze up".
