When it comes to doing work on the house one of the biggest things you will ever need to do is replace the heating system, and this usually means spending quite a bit of money. Many people are put off changing the heating system because of this fact, but it must be remembered that replacing the old gas boiler will usually mean much better heating and therefore long-term savings due to less fuel being used.
In order to get the best deal when buying a new gas boiler it is important to think about the boiler efficiency rating, since this will affect the price but will also affect how much fuel the unit will use in order to create a certain amount of heat. Buying a high efficiency boiler is much more expensive than the average boiler type, but this will usually lead to much better heating and probably result in lower fuel bills, especially over the long term. Many high efficiency models also get a tax credit, which means the unit can be bought more cheaply to a certain extent.
Another thing that will affect the price is how much installation work will need to be done. If you already have a gas boiler installed and all the pipework and ventilation ducts are in existence, the job can be done fairly cheaply in many cases. However, if you need to run new pipework and have new ventilation systems installed this can add several hundred dollars or even $1000 or more to the overall bill.
You also need to bear in mind that government regulations may have changed since you had the last boiler installed, which can mean there may be extra work needed to be done. Make sure that the estimates you get from a heating contractor includes all the work that needs to be done and will not give you any surprises for extras once the project is completed.
Some of these extras can include electrical work, venting, and also getting rid of the old boiler itself. Make sure that all these are part of the contract before you sign.
Installing a new heating system will always be a large job, but by making sure you do all the proper research and understanding exactly what the job entails you are much more likely to be able to get the job done at a decent price, and end up with a heating system that will not only keep your house warm but also save on fuel bills for many years to come.
