My house is coming up for 20 years old and the boiler in there is still the original which, I understand, is likely to be worth replacing given how poorly it performs on the energy efficiency tests at the moment. I understand that there's a direct replacement available in the shape of the Greenstar 440 CDI. Can anyone comment if this is the best thing to go for - a direct replacement, or have things moved on significantly in 20 years that something else is a better option? The current unit has shown no problems - we've owned the house for around 6 months now. Had it inspected when we moved in and the chap said it's in decent nick but not worth repairing if anything does go wrong.

House is five bedroom, four bathroom (1x main with bath, sink; 1x ensuite with shower/bath, sink; 1x ensuite with shower and sink, 1x downstairs with sink). It has a total of 15 radiators, a mix of double and single panels. Total floor space is around 2100sqft. Searching through and reading other posts on here, I'm not sure what size the various pipes are - I can find this out later on. The current boiler is in the garage and easy to get to, there's plenty of space around it if something else needed to be installed. Pipework is all easily accessible to facilitate this if required. I don't know what the flow rate of the water is - not sure this is something I could easily find out. Do I just see how many litre jugs I can fill in a minute from the cold tap on full whack?

Total residents: Me, wife, 1x 18 month old.

Thoughts welcome!

The 440 really is a Rolls Royce, made in Britain top quality. If you get a new boiler get the system flushed. You can get up to 10 year warranty if fitted by an accredited installer.
The controls are a lot better than you have now.

Really great boiler

Personally if there's space I'd always go for a system boiler and unvented cylinder - far less complicated if things go wrong :wink:

As always help on here is free, however if you think you have saved a decent sum of money why not click the link to find out about the charity we're currently supporting? A couple of quid makes a real difference.
