Combi boilers have 6 copper pipes exiting the boiler which is easily identifiable - There could be 2 pipes popping out the top and 4 exiting the bottom or ANY combination.
If in any doubt just send us some photos on WhatsApp showing the pipes like the photo here 07914008149 - No mad panic we are here to help.
Let's be clear this set up will pump out at least 8 litres of hot water per minute 40 Degrees centigrade - Electric showers will only manage 2 litres per minute at the same temperature.
If you have a hot water cylinder then what you really need is a Power shower !
So you have a primary boiler with a hot water cylinder similar to the image - This is stored hot water vented cylinder, you will probably have a large plastic tank above the cylinder or in the attic. You may not have a boiler connected to this cylinder - Some are electrically heated by an immersion inside the cylinder.
We can get 8 litres per minute from this cylinder with one of our Power Showers.
