How can some people get their boiler replaced for under £1,800 and others pays over £4,000?
The differences in boilers can be vast. They produce different amounts of power and come with different warranties, different components and different applications. There are 3 main types of boiler:
Hot water and heating usage
The size of the property that the new replacement boiler needs to heat
For a modest sized house with one bathroom and perhaps an en-suite, a combi boiler will be more than adequate for the hot water needs.
In a large house with multiple bathrooms and hot water outlets, a combi boiler would be less suitable. A combi is directly supplied by the water mains coming into the property, so the flow can be affected by opening other taps. A heat-only or system boiler uses an insulated cylinder of stored hot water. This means that several taps can be used at the same time.
A property with 30 radiators will need a new boiler with significantly more power than a property with 8 radiators.
Our engineer can help you decide which type of boiler would be best for you, along with the KW output
Some Dynamic Gas customers change their boiler when it breaks down and doesn't work anymore. This can cause distress as having no heating or hot water, particularly in the Winter, can be a very unpleasant experience for you and your family. Other customers know a boiler replacement needed soon and decide to get a new boiler fitted before the old one breaks down. When you decide to change yours is completely up to you.
An engineer can tell you when your boiler is about to break, but often you'll see the signs yourself. However, you may not understand the engineer's technical jargon. We've simplified the signs and terms for you below:
A gas engineer might describe your boiler as beyond economic repair, so you need a replacement boiler. However, it doesn't mean that it can't be repaired. It just means that repairing it may cost you more than purchasing a new boiler. Older units contain parts that are harder to source, older boilers tend to be more complicated to fix. When some parts start to fail, the other parts are just as old. It would be cheaper and safer to have a new boiler replace the older unit than to pay for multiple repairs.
No matter what state your boiler is in, Dynamic Gas can replace your boiler. Unlike other schemes and government-backed grants, the only criterion we look for is that you own the property. It's that simple.
An older boiler can be extremely inefficient. Boiler efficiency is rated on a SEDBUK band (Seasonal Efficiency of Domestic Boilers United Kingdom). Both the Viessmann Vitodens and the Worcester Bosch boilers are in group A. Older boilers can be in any group up to G, which is less than 70% efficient. According to the Energy Saving Trust, a new group A boiler can save you over £300 per year on gas.
This is a common feature on older boilers and a real waste of gas. All the time the pilot light is lit, it's burning gas and costing you more. New boiler installations have automatic ignition, meaning no gas is burned unless it's needed.
If your boiler is mounted on the floor, it's likely to be very old and inefficient. A wall-mounted replacement boiler will be more efficient.
If you're making changes to your property. If you are extending either the heating system or the demand for hot water, you need to check what the boiler can cope with. Boilers can often be working at their limit. Once more load is added, it may not be able to produce the heat required, or worse, may break down. Changing your boiler may also add to the value of your property.
In the very early stages, we suggest that you establish the amount of power you need your new boiler to have. A boiler that produces 24KW is much cheaper to buy and install than one which produces 34KW. But be aware that if your boiler can't produce enough heat, you won't have a warm home.
This can be a key difference in the quotes you might receive. As smaller Kilowatt boiler will be cheaper to install, but might cost you more in the long run in parts as it struggles to heat your property. Likewise, an over-large high power boiler will run inefficiently and cost you more money on your energy bills. The Institute of Domestic Engineers has a good online calculator that can work out the size of the boiler that you need.
Alternatively, you could just ask the Dynamic Gas surveyor when they visit your property. They will be using a similar formula to calculate the size of the boiler you'll need.
There are many different boiler brands on the market. Each company will have their preferred brands as that's what they are used to. We focus on two boiler manufacturers; Viessmann and Worcester Bosch. We believe these manufacturers to be the best available.
The Worcester-Bosch Greenstar i combi boiler is the replacement for the well-established award-winning Greenstar i Junior, which has been installed in over one million homes across the UK.
Perfect for small to medium sized homes with one bathroom, the boiler's new features have been designed based on feedback. These boilers now include increased outputs, higher hot water flow rates of up to 12.3 litres/min, a user friendly control panel and a larger condensate siphon that eliminates the risk of condensate freezing.
With its downward-firing gas to water primary heat exchanger, the Greenstar i range is in a league of its own, ensuring maximum heat displacement per KW of gas used.
The Viessmann boiler is the number one best seller in Germany with an astonishing 1 in 3 homes having one installed.
Its innovative Inox Radial heat exchanger is one of the best in the business.
The Viessmann range also comes with a fully comprehensive 10 year warranty.
Worcester Bosch is the biggest name in boiler replacements.
They have been around for decades and have boilers installed in all parts of the country.
Their customer service is excellent, as is the quality of the boilers they build.
Which? Magazine produced a really good boiler guide which we recommend you read before speaking to anyone about boilers and which brand to go for.
The longest one available – what most customers want is a 10 year guarantee. Just remember to get the boiler serviced according to the manufacturer's guidelines and their guarantee will typically last longer than the payment period you have with us.
