Heat only boiler to combi upgrade

[Brambles]

Yes, buy a flow (weir) gauge from screwfix - about £15

You could write a review too after you have used it!

Great, so if its over 16 litres per min go for the combi?

 

[Riley]

Get a container you know he volume of and fill it from an outside tap ideally and time it.

 

[Riley]

Ha ha buddy you are on a professional/diy plumbing site I don’t think any of the guys here are going to say that the combi is the way to go

 

[Brambles]

I would say that to get the full dhw output at the boiler (40kw) you would probly need nearer 19 litres/minute at the mains outlet. If you are getting a lower flow look at the 32kw version or consider adding a pumped accumulator

I'm smelling DIY gas work about to take place.

1st of all a mate was going to sell him a 40kw boiler cheaper than anyone else could ever get one now looking at screwfix to buy a boiler.

Had a person lined up to convert from cylinder to combi for £600!

I'm out 😎

Lol i was looking for reviews on the boiler in question no harm in doing that! How have you come to that conclusion by me just posting a review that i found on screwfix if it was DIY i wouldn't have raised the point!

Thanks for your input thus far

A storage combi is a perfect compromise. Problem is it wouldn’t fit in the same position the existing boiler is fitted.

Could it be located elsewhere?

Yes. All of these things are relocatable in 95% of cases. Your limit is your budget.

Apologies i thought it was something separate that would connect to the boiler🙄

No it’s one huge boiler with a small water store built into it

Well I say huge it’s not but it’s a damn site bigger than a normal boiler

Haha no worries, thanks for all your help and advice and others, will buy a flow gauge and report back on the flow rate

Easy way to test how long to fill a 1l bottle for 16lpm your looking for around 4 seconds maximum
