This is a flow cup, and with this, we can measure the incoming cold water supply and size your combi boiler to suit.

This is where a proper home survey is necessary. If someone has been out to survey your home for a new combi boiler, and they didn’t use one of these. This could be costing you money!
Let’s look at Worcester Bosch as an example. There are four different sizes in the Cdi range
|Hot water flow rate litres per minute @ 35* rise|
|29 Cdi||30 Kw||11|
|34 Cdi||30 Kw||12|
|38 Cdi||30 Kw||14|
|42 Cdi||30 Kw||15|
As you can see from the chart above. The heating output is the same across all four models. The only difference other than price is the hot water performance. This is where the flow cup comes in to play.
If the cold water coming into your house is at 11 litres per minute. You are only ever going to get 11 litres per minute out the other side of your combi boiler. In this scenario, there would be no point going with anything other than the 29Cdi.
The difference in price between the 29kw and the 42kw is near £600.
The reasons for having a proper home survey done by a reputable company should be clear. You could save yourself a few hundred pounds!
