Hi there,
I've a Potterton Puma combination boiler which fires up okay when the hot tap is turned on, but fails to stay hot for very long. After 20 secs or so the water turns cold and then back to hot after another 20 secs. Makes a shower of any length rather hard work.
I'd be really grateful for any advice and also an estimate for any work required.
Huge thanks in advance
