Boiler Replacement

[hagan10]

Evening All,

I currently have a potterton prima b (vented system) fitted to a 4 bedroom detached house (around 21 years old the boiler), i have only recently moved in.

The heating is on but is not getting the house warm.. (radiators only getting warm, not hot hot when boiler on highest setting)

Microbore is fitted

I am wondering could it need a boiler replacement or a magna cleanse? there is no filter fitted to the system at the moment, not sure if the previous owner had a system flush etc

Would i notice a difference with a magna cleanse?

thanks

systems sludged up as heat wont travel through it

21 yr old system, be worth replacing the lot for a well designed and specced system

A good clean might help, but to be honest, after 21 years, and bearing in mind that its microbore, if you can afford it - start again from scratch.

21 years ain't that old for a ch system. I would look at a new boiler, magnacleanse the old system, add a filter in the return plus trv's on the radiators.

Do you know if the pipework is plastic pushfit or copper pipe throughout. I would advise on replacement if its pushfit. If Copper a good cleanse of the system and being microbore i wiuld be inclined to take the rads off and flush through and cleanse pipework and fit a good quality filter and trvs afterwards

Agreed, I was at an house the other day with a 17 year old system and works absolutely fine - no issues at all.

I agree with GasSafe.

Hope you get it sorted

my home has a system that was in place when we moved in 23 years ago on microbore which works very well

It is a good boiler,it could be the boiler not working correctly,is it taking a long time to come on maybe even though controls are on or it could be a circulation problem,just because micro bore ,no reason to jump to the conclusion blocked ,if chemical inhibitor has been added,should be ok,best to get a gas safe engineer out with boiler certification,to check out the system

I would change boiler and all the rads if you can afford to as the newer radiators put out more heat and for the boiler to be covered under warranty etc you would have to pay someone to remove rads and flush through which won't get all the rubbish out anyway so i would put money towards new radiators and flush the pipework through also i would try to seal the system (get rid of the small tank in the loft)
I Would fit a Magnaclean or equivalent If fitting a new boiler

Wooow!!! maybe a new bathroom as well

Why ?

In my opinion if you change a boiler it is sensible to upgrade radiators too as new rads put out more heat as said above and if the boiler is 20 years old most likely the rads are too and have probably been painted 10 times which would also insulate the radiator reducing the output

If you flush the system which you should for a new boiler then most of the clean time is in the radiators so if you were to change the rads rather than spend time flushing each through the labour to flush a radiator would cover the labour to fit a new rad

I do agree with what you have said though about checking if boiler is running correctly and pump is working etc

B4 you go spending out loads of money, get someone in to check out boiler, may just need a service, and gas chacking
