Hi guys - here's a quote from the 'Supply requirements' information for a combi boiler I'm interested in :
http://www.worcester-bosch.co.uk/index.php?fuseaction=product.detail&con_id=231281&detail_id=127860
"Where back-flow prevention devices, including water meters, are fitted the expansion of hot water into the cold water main can be prevented. This can result in a pressure build-up that may cause damage to the boiler and household devices such as showers, washing machines etc. In these cases we recommend that a mini-expansion vessel (Part No. 7 716 192 105) be fitted adjacent to the boiler in the cold water main."
Are expansion vessels fitted to the mains water inlet pipe as standard practice on combi systems, or aren't they generally necessary ?
I didn't have a separate expansion vessel fitted to the combi system in my last house, but then I didn't have a water meter.
I do have a water meter in my current house which is located in the pavement outside.
Will I need to get one of these expansion vessels fitted do you think ? Are there any other factors that I need to take into account ?
Cheers.
