Hello forum.
I am currently in the middle of a loft conversion in which we are installing a second shower in the new ensuite. I'd be really grateful for advice on what heating system upgrade we require to be able to adequately serve the ensuite shower in the loft while the existing shower is running.
Current system
We currently have a slightly temperamental 15/20+ year old combi boiler and the mains pipe feeding the house is 15mm. I have measured the flow rate at the outside tap to be around 18 l/m. The cold water flow rate out the cold tap in the first floor bathroom is about 16 l/m. I don't have a pressure gauge to measure mains pressure, but can get one if necessary(?).
What we are aiming for
We would like for both showers (the existing first-floor shower and as yet unbuilt ensuite shower) to be able to run concurrently at adequate pressure and temperature.
What are our options?
Whatever route we go down, we will need to replace the existing boiler. We had planned to install an unvented cylinder and system boiler, but I am unsure if we require it and whether we might instead need a system that will provide additional pressure to the system (eg. an accumulator tank + new combi or Homeboost + new combi).
I'm struggling to get my head around what the most suitable route to go down is. I'd be grateful for any advice on what setup would likely work best or if there are a few options that could work. Let me know if you need further information.
Thanks
