Hi,
First off great forum, it’s kept my 28 year old Worcester PJ12/14 combi oil boiler running for waaaay longer than it should have and that brings me to the reason for my post.
I bought the house I live in 5 years ago and carried out two extensions during which I moved and re installed the oil boiler in its current location. I've just fitted a new oil pump to the PJ12/14 to get it up and running (again!) but the time has come for me to bite the bullet and retire the old girl.
I have contacted a local OFTEC engineer who was recommended to me by the builders who carried out a couple of extensions to my house a few years ago.
He visited last night and made some recommendations and statements regarding new boilers which I would appreciate a second opinion on.
First off he informed me that if I fit another combi boiler it will give me more problems than my current boiler due to the nature of manufacturing of new boilers and he also stated that the likely life of a regularly serviced combi boiler would be about 7 - 10 years.
His reasons were that living in a very hard water area (Norfolk) that degradation to the heat exchanger would rapidly reduce the efficiency of the boiler. Working as a Commissioning Engineer for Anglian Water I can appreciate that 1) mechanical and electrical components are no longer built to last and that 2) calcification due to hard water are real problems.
Based on this his advice was to fit an unvented cylinder system which he stated will last longer and not suffer from calcification and will be providing me with a quote for installing both types of system.
He also said he would install a magnetic "water conditioner" to help prevent calcification in the combi boiler which as an engineer working in the water industry I an extremely sceptical about as many chemical engineers I work with have said they don’t work.
I would appreciate your comments on the above considering the following:
1) I have a small family just me the wife and our son and we are very water and energy conscious keeping heating and hot water usage to a minimum.
2) We have an open fire in the kitchen / living room and an solid fuel stove in our living room which we use as secondary heating sources or as primary heating when we only need to warm the place a bit.
3) We have a 4.5 bar cold water supply pressure (measured last night).
4) I can and do fix and service just about every appliance I own.
Could anyone also comment on water conditioners and recommend makes of oil boilers, the engineer recommended Worcester Camray for a combi.
Sorry it’s such a long post but this will be an expensive decision which I do not want to get wrong.
