WARRANTY CONDITIONS 

With due regard for the conditions indicated below, Intergas Heating 
Ltd warrants to the authorised installer the soundness of the 
materials used in and the correct operation of its Central Heating 
products, when used for the purpose for which they are delivered. 
As the occasion arises we should be enabled to ascertain, on site if 
necessary, the soundness of the warranty entitilement. 

The warranty comprises: 

The warranty is limited to the free-of-charge resupply of parts that 
during the warranty period, entirely in our judgement exhibit 
material or manufacturing faults that are not the result of normal 
wear etc. Such parts should be sent to us carriage paid together 
with an indication of the defect and after replacement become our 
property. 

1.

 

The warranty period on parts is 2 years calculated from the 
date of installation. The extended warranty period on parts is 3 
years calculated from the date of installation. The extended 
warranty is effective only if the annex to the warranty 
certificate has been signed by the purchaser and returned to 
us within 8 days of the date of installation.  

2.

 

The warranty period on the water tightness of the boiler’s heat 
exchanger is 10 years, provided however that if, as a result of 
corrosion, leakages arise which in our view cannot be rectified 
on site, we will exclusively supply that boiler part on the basis 
of old for new, calculated at the time of replacement from the 
installation date. 

3.

 

The warranty ceases to apply if it is ascertained that the 
defects, damage or excessive wear are attributable to 
improper use or injudicious treatment or inexpert repair, 
setting, installation or maintenance by unauthorised installers 
or to the product being exposed to substances containing 
aggressive chemicals (including hair lacquer) and other 
harmful substances. 

4.

 

The warranty also ceases to apply if pipes and couplings have 
been used in the installation which can cause oxygen 
diffusion, or if the defect is the result of depositing of boiler 
scale (harmful to the boiler and the installation). 
Surface damage and transport damage are not covered by the 
warranty. The right to warranty ceases to apply if it cannot be 
demonstrated that, after commencement of use, the central 
heating boiler has been serviced at least once a year by an 
installer authorised for that purpose by or on behalf of the gas 
company. The instructions for installation and use which we 
issue for the boilers concerned should be complied with in full. 

5.

 

The manufacturer’s liability under the agreement is expressly 
limited to fulfilment of the warranty obligations defined in this 
article. All claims for compensation, except for those relating 
to failure to fulfil the warranty obligations, are excluded. With 
due regard for the mandatory provisions regarding product or 
other liability, no rights may ever be derived at any time with 
regard to any consequential loss, loss of net worth or any loss 
whatsoever that might arise from defects in materials 
delivered or work performed by the manufacturer.                                                                                                                                                                    
In addition, all offers and agreements concerning deliveries 
and/or services to be made or provided by us are governed by 
the Conditions of Sale. A copy of these conditions will be sent 
to you free of charge on request. Conditions to the contrary 
are expressly rejected.  

 
 
 

 

6.

 

The warranty is effective only if the annex to this warranty 
certificate has been signed by the purchaser and returned to 
us within 8 days of the date of installation. By signing the 
warranty card the purchaser states his/her agreement that the 
items have been delivered in good condition. 

7.

 

If the installer’s business has been terminated before the end 
of the warranty period, the user may invoke our warranty 
obligations to the installer. 

 

 

 

Installers are required to carry out installation, commissioning and 
servicing work in accordance with the Benchmark Code of Practice 
which is available from the Heating and  Hotwater Industry Council 
who manage and promote the scheme. Visit 
www.centralheating.co.uk for more information.
