Aftercare and boiler insurance
Once you have bought your new boiler, it could be a good idea to look into getting some boiler insurance as well.
Although you would not expect your new boiler to breakdown immediately, if it did and you are not insured it can be costly.
Boiler cover will give you peace of mind that if the worst happens and you are left without any heating or hot water. I recommend you save the money in a separate account, by the time the boiler goes wrong there is easy enough in the account to cover the cost, the remaining money is considered profit.
There are three types of condensing boilers, Combi boilers, system boilers and rgular boilers. The main difference between these is the use, or elimination of, various parts within a typical system such as the hot water cylinder or the expansion tank. For more information see the relevant pages in this site.
Possible side effects
Condensing boilers are often noted for their ‘pluming’, a feature sometimes mistaken for ’steam’ coming out of the flue. This is caused by water droplets held in suspension in the flue gases condensing in the colder outside atmosphere. Although non-hazardous ‘pluming’ may be a nuisance if the condensation interferes with windows so care is needed in positioning the flue pipe to avoid this. Also a small pipe need to be run to a drain to allow the condensate to flow away.
The law in England & Wales changed in April 2005, which means only a condensing boiler can be fitted as a replacement boiler or complete new installation. There is a minor loophole to this law where, in exceptional circumstances, the local authority, can agree to an exemption certificate allowing a non-condensing boiler can be fitted.
