Why Gas Call Services?
Gas Call Services has been carrying out installation work for a number of prestigious clients since it’s inception. We have a dedicated Central heating Installation department who will deal with the whole job, from the survey through to quality audit upon completion of the job. We will typically install around 2000 central heating systems a year. Our labour and parts are guaranteed for two years.

Are you paying too much for your fuel?
Keeping your home warm and having hot water is important to us all -but have you ever considered that it could be costing you far more than necessary? Gas Call Service's range of condensing boilers and central heating systems mean more than just reliability. Their tried and tested modern features offer many extra benefits and cost saving efficiencies, all installed by fully qualified CORGI registered Engineers.

Our fully qualified Heating Surveyors are able to advise you on our range of boilers and central heating systems. Their modern features offer the following:

• Up to 30% lower fuel bills and higher efficiency
• Environmentally friendly patented technology
• Flexible siting - floor or space saving wall mounted
• Stylish and unobtrusive design in a range of sizes
• Free, 2 years parts and labour guarantee
• A range of ‘combination’ boilers that give instant hot water without needing a hot water cylinder
• Easy to use control packages that can add to further savings
• Choice of new technology radiators that gives instant heat with minimum use of fuel

Which boiler is right for you?
Although boilers differ in size and whether they stand on the floor, hang on the wall or sit inside a fireplace, probably the most important difference is the way they produce hot water for washing, bathing and showering. Traditional boilers and system boilers heat water in a storage cylinder, typically sited in an airing cupboard. Combination boilers heat water instantaneously (via a special heat exchanger inside the boiler) only when you open a hot tap.

Traditional boilers are the simplest kind, with the fewest components inside. System boilers and combination boilers are more complex and tend to be larger because they always include the pump which circulates water through the radiators, and an expansion vessel to accommodate the increase in volume when it gets hot.

Traditional and system boilers with stored hot water systems are best suited to family homes where hot water demand is usually greatest. The average combination boiler is best suited to single households or couples with modest hot water needs.

A Traditional Boiler
Traditional boilers are available in a wide range of designs and outputs to suit almost any situation. Back boilers save space by sitting inside a fireplace opening and are cost effective like-for-like replacements. Wall mounted boilers can be small enough to fit inside a kitchen cupboard and still be powerful enough for the larger property. A traditional or system boiler (one with some system components built into the case) can deliver lashings of hot water to several taps simultaneously. You need space for a cylinder as well as a boiler but modern versions are often surprisingly compact. You also have to anticipate your hot water need but modern controls make it easy to plan around your daily/weekly routine and the new generation of 'high recovery' cylinders are designed to cater for unexpected demand.

A Combination Boiler
A combination boiler heats water instantaneously whenever you open a hot tap, so you don't need space for a storage cylinder. In Summer there's often a delay until it reaches working temperature but the supply is endless. The temperature at the tap is dependent on the temperature of the mains supply and the flow rate. In Winter the delivery of usefully hot water can be very limited - perhaps taking two or three times longer to fill a bath than a traditional system - and simultaneous demand by a shower and, say, a washing machine can result in a trickle at each. The latest models feature high outputs, small stores or pre-heating systems designed to supply more hot water and with minimal delay to save wasting water.

Look how inefficient old boilers can be
Even the best maintained boiler can end up costing you more than it should. Most boilers that are older than 10 years are typically only 67-70% efficient, which means around a third of the fuel they use goes to waste. As they get older, they become even less efficient and less reliable. By comparison the new technology of Gas Call Service’s range of condensing boilers make them ultra efficient. They have not one but two heat exchangers and convert up to 93% of the gas burned in to heat.

The above table shows the average gas fuel bill costs and you can see that in a semi-detached house a new condensing boiler could save you as much as £142 per year.

How modern technology is driving down fuel bills
The new condensing boilers can save between 15-20% on gas consumption over standard boilers. Compared to boilers over 10 years old, the energy savings can be as high as 35%. Modern boilers convert up to 93% of the gas burned to heat.

This effectively extracts more heat from the gases to heat the water in the central heating system. Only 7% of heat is lost through the flue, so you burn a lot less gas for the same amount of heat.
