Its happened  your 15 year old gas boiler has stopped working  again free-boiler-grantsand is on its last legs and you dont want to spending money on repairs again.  You have even had it power flushed but It’s finally time to start thinking about getting a new one, but you have no idea what it’s going to cost as the last time you purchased a new boiler is a fuzzy distant memory.

This guide to gas boiler replacement costs will provide you with greater knowledge to make the task of upgrading your central heating system a bit less scary another option wich could save you mony would be to get a power flush caried out.

How do you figure out what system you have? Well if your hot water is heated from your gas boiler for immediate use and you don’t have a hot water cylinder then you probably have a combination boiler or “combi”. If you do have a hot water cylinder then the gravity fed system can be identified if you have a cold water tank and an expansion overflow tank (often in the loft of a house).  High pressure (unvented systems) are less common however do not use tanks in the loft and provide water at mains pressure.

If you currently posses a combination boiler and you are pleased  with its performans then a like-for-like replacement is a great option. after considering the output of your old boiler you may wish to consider chosing a more powerful boiler if you want to boost the hot water supply for a more powerful shower.  Combination boilers of 30kW and upwards are presently available.

 Well now you have a better view of what system you want, let’s try and get a better idea of the gas boiler replacement cost. There are some general costs and a number of costs that depend on the state of the current system.

Below are some broad costs for various elements of the replacement:

regarding gravity fed central heating systems the choice gets more complicated. not many heating engineers at the moment will suggest you get a gravity fed system for a completely new installation because  they have a few limitations – not least a cold water tank in the loft that has the potential to burst and result in water damage.  but if you are on a budget and happy with the heating system then a like-for like replacement is certainly a realistic option. For flats and 1-2 bedroom houses where the hot water use is relatively low then a combination gas boiler can also be a descent option. Replacing a gravity system with a combi is usually quite easy and will make space where the hot water cylinder is sited.

There are two sorts of boiler that can be used when replacing: system boilers and heat onlyboilers. alot of older boiler systems have external pumps that move the heated water around and for these a heat only boiler could be used. A system boiler has the pump built into the boiler itself, which lessens the plumbing an installer is required to do but it does increase the cost of the boiler. So if the rest of your system is fine then a heat only boiler can be a good option whereas if you need to replace other elements it may be worth considering a system boiler instead. another option which could sovle alot of issues for a fraction of the price would be to get a central heating power flush. visit here to find out about the central heating power flush cost
