I currently have a 4 bed converted bungalow which has 2 showers, a bath and 10 radiators. The property is being converted to have 5 bedrooms, 3 showers, a bath and 12 radiators. The boiler is a Worcester 24Kw combi. It works ok but we do get pressure issues sometimes when someone is in the shower and a toilet is flushed or the washing machine is on.
One of the builders who has quoted for the job has said that the combi needs to be replaced for a pressurised system and a tank. Another builder says that a combi will be ok but a bigger one will need to be fitted. I mentioned it to a plumber who said that combi's can be used for larger properties but its not recommended due to the pressure issues.
I am not sure what to think. A bigger combi will be the cheaper option but if there are pressure issues once installed, we are stuffed.
Any advice greatly received.
Thanks
