Can anyone advise the kw / BTU rating of my GlowWorm Swift flow 80 fanned flue combination boiler with Honeywell gas control.
My builder has installed a Aqualisa Quartz Digital shower which requires a minimum domestic hot water rating of 24kw (80,000BTU) and the type fitted with a fully modulating gas valve.
The shower is not functioning properly and I suspect its the kw/BTU rating.
Any help you can give me would be appreciated.
