Flow rate for cold water and then boiler
Anonymous user 28/02/2024 - 3.46 PM
I have a cold water flow rate of around 14l/min and my current boiler is a baxi duotec 28 he which is on its last legs. Would a similar lowered boiler be sufficient for the cold water flow rate? I only just bought the property so not really sure how the current boiler performs in the coldest of days but wondering if a boiler with a flow rate of 12l/min is good enough or if I definitely need one that covers my cold flow rate
Are you a tradesperson and able to answer this question?

I would go with a boiler that can heat 14l per minute. You might not notice the difference, but the price of a boiler that can do 12 isn’t going to be much different to one that can do 14

Hi
You're looking for around a 35kw combi I would say. Then the heating load to be regulated down on the boiler to suit the size of the central heating system for maximum energy & cost efficiency 👌
Any advanced installer or boiler technician can advise you what boilers can be fine tuned to save you money 😁

It really depends on how many hot water outlets you have and amount of people in the property but even a combination boiler with a hot water flow rate of 10ltrs a minute would do the job.

Meeting the flow rate would mean good hot water flow rate, however to find a boiler to hest 14l/min maye mean a bigger more expensive boiler. Just getting a bigger boiler doesnt mean better performance. Condensing boilers are more efficient when they are working harder, i.e correctly size for the property and hot water demand
